REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 7 of 119 1 Introduction The REA VeriCube is a measurement device for the quality control of printed 2D matrix codes and 1D barcodes. This is a stationary device, which has to be connected to a PC via an Ethernet network. The application software along with the device driver and the display of the test reports run on a computer running Microsoft Windows. In contrast to a scanner for barcodes and matrix codes, REA VeriCube is an optically operating measurement device. Measurement devices are subject to a regular adjustment and calibration (monitoring of testing equipment). Adjustment and calibration (monitoring of testing equipment) can be performed by the operator and as long as calibration is successful, there is no need to return the unit to the manufacturer. An overview of all Verifier variants and brochures can be found on our website: https://www.rea-verifier.com 2 Delivery scope The REA VeriCube in its basic configuration is delivered in cardboard packaging and fitting foam padding with the following parts: 2.1 Basic configuration 1 REA VeriCube, test unit with operating unit as per delivery note (see following chapter for available types) 1 optic module, exchangeable, according to the delivery note (built into the unit) 1 Plexiglas dust-protection cover – built-in in transport (must be replaced with a glass plate during commissioning) 1 anti-reflective glass plate (08316280) (separately packaged) 1 GigaBit PoE power supply unit (100–240V, 30W) (06113003) 1 power cable for the ordered plug standard (Euro, UK, US) 2 network cables, highly flexible, RJ45 CAT7 (08316608) 1 printed operating manual (this document) 1 USB stick with software and documentation (08316300) 1 calibration card, serialized, in a protective envelope (90031702) 1 test report of the reference code of the calibration card, created with the delivered VeriCube for documenting the delivery status 1 test report of the reference code (req. for test equipment monitoring)

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 12 of 119 3 Transport, storage and operating conditions The REA VeriCube can only be transported in the supplied case or transport packaging. Transport: The REA VeriCube is delivered in a case or in a cardboard box with adequate foam padding. This package should be preserved for possible transportation. The REA VeriCube should only be transported in its original packaging, especially with parcel services and similar means. In case, it is shipped without the original packaging though, it should be packaged with good padding, so that the device cannot move in the cardboard shipment box. The glass pane must always be removed for transport and the plastic pane must then be used as a protection. The glass cover must always be removed prior to the transportation and then the plastic cover must be used as protection. After transportation, the device must be warmed up to room temperature because the optical parts can be fogged by the temperature change. Storage: The device should always be stored in dry, dust-free rooms and at room temperature. When not in use, the device should be covered or stored in the transport packaging to protect it from dust deposits. For storage, remove the glass pane and insert the plastic pane. Dust on the optically effective surfaces leads to misalignment of the optical measuring paths. This leads to incorrect measurement results. Operation: Humidity, cold, heat and mechanical impacts incurred when the equipment is dropped, can lead to a situation where the measuring chamber cover as well as the mechanical and electronic parts can be damaged or destroyed. If the device still provides measurement results with these damages, there is a high risk that these results are incorrect or deviate too far from the correct values. The device is delivered with a plastic cover and a top plate, which protect the measuring chamber. The plastic cover serves as dust protection during the storage and transportation of the REA VeriCube. The glass plate serves as a top plate in the event that the codes to be measured need to be placed on the surface. The glass top plate must always be removed prior to the transportation and the plastic cover used as protection. ATTENTION N

In dusty environments, it is recommended to protect the device and cover it if possible. Electrostatic sensitive parts Electrostatic discharges should be avoided as they can destroy the device. Functional test It is recommended to do a monthly review (calibration) of the accuracy of the verifier by measuring the supplied test code.(See Section 11 Calibration)

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 15 of 119 4.2 Additional safety instructions for REA VeriCube UV In addition to the safety instructions in chapter 4.1General safety the following must be observed when operating the REA VeriCube UV: Attention! The device works with UV radiation. It must only be used with appropriate protective measures in accordance with EU Directive 2006/25/EC In countries outside the EU, it is obligatory to comply with the occupational safety regulations that are in force in that country. The warning sign "UV radiation” must not be removed from the device or concealed or made unrecognisable in any other way. UV protective glasses are supplied with the unit. It is recommended that these glasses be put on before the installation or commissioning process and before each power-up. The unit switches on the UV-LED's during continuous operation. The unit should therefore only be installed in a room where it is not possible to enter without taking protective measures (wearing UV glasses). With REA VeriCube UV the irradiation values according to EN 62471:2008 for the skin directly on the device are exceeded. For longer-term work at the radiation source it is therefore recommended to wear opaque clothing and gloves. During operation, please always cover the field of view with the black plate or black cover cloth after the object has been positioned. The use of the device is the sole responsibility of the user. The manufacturer REA Elektronik GmbH is not liable for any damages caused by the use of the device. This exclusion of liability is only limited by legal regulations that apply to contracts or transactions between companies (BtB). The manufacturer REA Elektronik GmbH has designed this product, REA VeriCube with UV LED's 365nm, exclusively for commercial use with appropriate protective devices. Use in private areas and / or without protective equipment is NOT intended use. The liability for damage resulting from such improper use, lies exclusively with the user.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 16 of 119 4.3 Electrical hazards Warning: When mains plug is unplugged or a main switch is switched off during cleaning, maintenance or repair work, appropriate measures must be taken to prevent unauthorized re-establishment of the mains connection. This applies to the power supply. The verifier itself falls under the category of Low Voltage.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 17 of 119 5 REA VeriCube Version 5.1 REA VeriCube Standard The REA VeriCube, in the standard design, has 13 screws on the upper side. With the exception of any two screws, all the others can be removed. The plate is either in blue or silver in color. The screws have Torx T10 heads. The screws are there to close the threaded holes. The threaded holes are provided for fastening the used fixtures when, for example, auxiliaries and other measurement aids must be affixed to the device. The advantage of this is that frequently made measurements of identical products can be performed by the device without the positioning aided by the live image function. 5.2 REA VeriCube Pharma The REA VeriCube in the Pharma design has a closed plate at the top without screw holes. This design is intended for use in areas in which it must be possible to clean the surface easily and quickly.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 18 of 119 5.3 REA VeriCube UV The REA VeriCube UV has an ultraviolet illumination as an alternative to the red light illumination with 660 nm. For this alternative illumination there are arranged 16 UV- LEDs with a wavelength of 365 nm in the unit. This applies to VeriCube devices with UV illumination  Devices can be identified by a warning sign:  Please read this manual completely before you start using the device! Please pay particular attention to the safety instructions for the REA VeriCube UV in chapter 4.1General safety + 4.2Additional safety instructions for REA VeriCube UV With REA VeriCube UV the irradiation values according to EN 62471:2008 for the skin directly on the device are exceeded. For longer-term work at the radiation source it is therefore recommended to wear opaque clothing and gloves. During operation, please always cover the field of view with the black plate or black cover cloth after the object has been positioned. The Level correction when adjusting this type of test instrument differs from the standard procedure. The greyscale card must be used here instead of the luminance card. Please refer to the note in chapter Level adjustment procedure for this type of verifier. Attention should be paid to the fact, that upon UV illumination, dirt will get visible, that was invisible with natural light before, like for example thin layers of fat, fingerprints etc. Extremely precise attention to cleanliness is a prerequisite for reproducible measurements. It is recommended to always wear gloves (e.g. Monochrom article no.: 5241L) when handling the device in order to avoid contamination of the verifier, the calibration / adjustment cards and the measuring objects.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 19 of 119 For the reflectance adjustment the blue component of the UV-LED light is used, which is within the sensitivity range of the camera. An absolute reference to national standards is not established in this case, but only a reference to the reflectance values measured with red light as a reference. This adjustment is used to obtain repeatable, stable measurement results that refer to a defined standard. The typical measurement objects are markings with dyes / inks / printing colors that are invisible or completely transparent in visible light. In UV light, these markings generate fluorescence in the visible range of the light spectrum. This light, which is generated by fluorescence is evaluated as if it were a reflected light from the surface. Due to the adjustment, described above, the UV light source has an always identical intensity. Thus, the fluorescence is evaluated with stable lighting values. The evaluation must be in accordance with ISO/IEC TR 29158 (DPM). Attention: The focusing plane of the camera module in UV is shifted in relation to that in red light. If the REA VeriCube UV is to be used for measurements with red light, it is essential that a suitable camera module is then used for red light.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 20 of 119 5.4 REA VeriCube IR The REA VeriCube IR has an infrared illumination as an alternative to the red light illumination with 660 nm. REA has two different versions for infrared lighting in its portfolio. The REA VeriCube IR can be purchased as a variant with 855 nm or with 945 nm. With these types of device, IR is always the alternative lighting to red light. For this alternative lighting, the device contains 16 IR LEDs with a wavelength of 855 nm or 945 nm. Handling, adjustment and calibration are the same with the REA VeriCube IR as with the standard device. However, it should be noted that due to unavoidable reflections through the glass pane, a warning appears during Level correction: "Level correction finished with a warning. Warning: the calibration card seems dirty. Please clean it. However, on this occasion the adjustment result has been accepted. [0x20081285].“ This warning can be noted in this case, but work can still continue normally. The reflections can only be prevented if both the adjustment and the measurements afterwards are performed without the glass pane. This is also permitted. However, it must be taken into account that the mirror in the device and the camera lens will then become contaminated by dust more quickly and therefore have to be cleaned regularly. As long as the device is not in operation it should be protected against dust. Attention: The focusing plane of the camera module with IR lighting is shifted in relation to that in red light. If the REA VeriCube IR is to be used for measurements with red light, it is essential that a suitable camera module is then used for red light. 6 Commissioning 6.1 Power supply The power for the VeriCube is supplied via a network cable connected to the device. This type of power supply is designated as Power over Ethernet (PoE) (power supply over a network cable). The delivered power supply unit provides power to a connected device only when the device is designed for a power over Ethernet supply. It is not recommended to connect a non PoE-enabled power supply device to the OUT connection of the power supply unit. A second cable or additional separate power supply unit is not necessary. The delivered network cables are, apart from the increased flexibility, standard off-the-shelf network cables.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 21 of 119 6.2 System requirements For the device power supply a mains connection in the range of 100 - 240 V AC, between 50 and 60 Hertz is necessary. The Windows software TransWin32 needs a standard off-the-shelf computer with a Microsoft Windows operating system, - Windows 10 Pro/Home, 64-bit. - Microsoft .net framework from version 4.5 or newer - One or optionally two Ethernet network interfaces (2 Ethernet network interfaces are recommended (at least 1Gbit/s, Auto detect between normal and Crossover) - Main memory: The minimum requirements of the used operating system must be respected. It is usually 4GB or more - Hard disk: The minimum requirements of the operating system must be respected - CPU: The minimum requirements of the operating system must be respected (a slow CPU increases the cycle time). - Mouse (with mouse wheel) / keyboard (supplementary touchscreen, if necessary) - Screen / graphics: Non-glare, minimum 48cm (19“), at least 1280 x 1024 pixels in resolution, color - Optionally: PDF program for the creation of test reports as PDF files (as printer simulation) - PDF display program - Firewall. The firewall must permit the network operation of the REA VeriCube The REA software TransWin32 is a single user software. The license is connected to the REA Verifier and not to the PC installation. The software does not need a dongle and can, if needed, be installed multiple times. Operation on a server is not a tested and verified installation by the manufacturer. As long as the server offers the REA program TransWin32 an environment, which reacts as a single workplace for the program, the server installation should work properly (virtual environment, sandbox, etc.). An installation under Windows XP does not function and is not supported. The minimum computer requirements are sufficient to run the system, however higher specifictions like the recommended configuration of the appropriate operating system in use, should be preferred. 6.3 Temperature change When the REA VeriCube is subjected to temperature changes (e.g. when it is utilized in heated rooms after transport in winter), condensation can occur on the optical parts. In such an instant, wait for about 15 min before the REA VeriCube can be used.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 22 of 119 6.4 Connecting The REA VeriCube is delivered with two identical network cables. Picture of PoE power supply and network cables The REA VeriCube is connected with one of the two Ethernet cables to the PoE power supply unit. The socket, which is marked on the power supply unit with "Data&Power Out”, is intended for the connection to the device. When the other "Data In" socket is used, the device does not receive power and will not power up. The "Data/In" socket on the PoE power supply unit is connected with the second network cable and with the computer (directly or indirectly). The picture shows an example of the connection of the Data-In socket to the network installation (here shown by the Ethernet switch).

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 23 of 119 The power supply unit has an IEC socket for connecting to the electricity supply. The mains cable is delivered adapted to the specified country standard according to the part number supplied. The socket type is C14 (IEC-60320). The plug type is C13. Picture of a socket, low-power mains plug type The power supply through the PoE is characterized by the fact that the power supply unit first checks whether a connected device is designed for a PoE power supply. In this test period, the device cannot yet be turned on. As long as the testing takes place, no LED lights up on the Ethernet socket of the REA VeriCube. As soon as the device receives power, the left LED lights up (light- orange) Picture of LED OFF Picture of LED ON ATTENTION: REA has a complete range of code verifiers in its product line. In all products, the power supply utilises PoE power. The REA VeriCube requires 30W type POI-3000 (or POI-3002 or POI-3004). The other devices use the 15W type POI-2002. When these power supply units are interchanged, the REA VeriCube gives the appearance of functioning. However, the measurement and the lighting do not function correctly. Therefore, the power supply units should not be interchanged. 6.4.1 Own Ethernet port The PC has one or two network connections, one of which is used exclusively for the operation of the VeriCube. The "Data/IN" socket of the power supply unit is connected directly with a cable to this socket.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 24 of 119 6.4.2 Network operation The PC is connected to a company network LAN. The REA VeriCube is connected from the "Data/IN" connection with an available and connected (patched) network socket. The server (DHCP) in the network automatically assigns the network addresses. When the company network is subjected to heavy network traffic, disruptions (the device shows network errors) may occur during operation. When these disruptions become too frequent, the network must be isolated by the network administrator or alternatively the REA VeriCube needs to be connected to the computer with a separate network connection (see the previous section). 6.4.3 PoE in switch Operation using an Ethernet switch, which supplies PoE power (instead of using the supplied PoE power supply) is possible. A connection, which can provide 30W power, is required. This mode of operation is the responsibility of the User and cannot be certified by the manufacturer. The PoE power supply is an industry standard and is, therefore, usually non-critical as long as a PoE switch is correctly specified and is not overloaded by too many devices. 6.4.4 MAC addresses Every network-enabled device receives a MAC address from the manufacturer. The MAC address is provided on the type label. Some network environments are configured in such a way that only known devices are allowable. In this case, please inform your IT department of the unit’s MAC address. 6.4.5 Firewall and network type When a firewall is active, it must be configured in such a way that the network operation between the PC and the REA VeriCube can pass safely through the firewall. During initial installation, the security rules are usually required. When the operating system recognizes a new network, it is asked whether this is a public network. This must be answered “NO” because Public networks are WLAN (at a railway station, airport, etc.) and not applicable for this device. When there are particularly strict security rules in a company or if the network is heavily loaded with data traffic, REA recommends using a second Ethernet port on the PC which is dedicated to the REA VeriCube. Supplied with the delivered unit, there is a document which describes the network integration in detail and also designates port details. In difficult installations, please refer to this document.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 25 of 119 6.4.6 Firewall and Network ports The installation contains several modules (see chapter 6.5). Communication between modules is performed via network components (Sockets, Ports). Ports that are utilized are listed in the following table. The Firewall must open the ports and let the program module communication pass through the Firewall. Transwin32.exe Port 127.0.0.1:23945 ServiceTool.exe Port 127.0.0.1:21947 MorpheusHost.exe Port 127.0.0.1:21946 MLV_Control_PC.exe Port 127.0.0.1:10061 VeriCube_Control_PC.exe Port 127.0.0.1:10051 Morpheus Broadcast PC-IP/device-IP: 10049 readb.exe (Article database) n/a If any of the program modules or ports are blocked then the application will not work or show odd behavior. 6.4.7 Using a gateway The REA VeriCube is using the camera protocol GigE Vision. This is primarily specified for a direct communication between two devices (PC and Camera). Operation over a Gateway is not recognized and does not work. 6.4.8 Fixed IP Addresses In some network environments fixed IP Addresses are demanded or required. This is usually solved by a manual configuration of the network settings of the PC and the VeriCube. A manual network configuration restricts the flexibility of use of the verifier. Therefore the use of a DHCP server is always recommended. The DHCP server manages devices which are identified by their MAC addreses. For each device requiring a fixed IP address the server is configured to provide such devices always and automatically the same (fixed) IP address.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 26 of 119 6.5 Software The REA TranWin32 software is necessary for the operation of the VeriCube. Only one REA VeriCube can be used by a PC at any one time. Other REA Verifier products can be used on this PC at the same time but not a second REA VeriCube. 6.5.1 Software installation When the system prerequisites are met (see chapter 6.2

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 27 of 119 System requirements), the TransWin32 program can be installed. For this purpose, the "Setup.exe" is launched. Depending on the version, the TransWin32 installation is offered directly or the TransWin32 button comes first and then "Install TransWin32". Administrator rights are required for the installation to be completed successfully. For normal operation, the normal user rights are sufficient. When the software for all users is installed, the "All users" documents folder is used. This general application folder must be available to all users without administrator rights. It is strongly recommended that all users have full access to the set directory for document storage. Restriction to read and write access may result in restrictions to some functions. The most secure and trouble free installation allows the user account for the installation to be an administrator account. In this instance the installation is performed only for this user and therefore only the Documents folder of the logged- in user is used. When the installation is carried out with "Execute as administrator", the installation is performed with the administrator account and not with the user account. In this case, it should be installed for all users and it should be ensured that all users have read and write permission to the "All users" document folder. In case of communication trouble (disconnects, error messages like Sensor errors) two basic solutions are available: 1. Within the TransWin32 menu “Tool” the installation of the Vericube Network driver is performed 2. A second Ethernet port is added to the PC and the REA VeriCube is exclusively connected to this port.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 28 of 119 6.5.2 Software and device options Select the desired language for the installation process The next step is to agree to the license terms.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 29 of 119 The following dialog offers a selection of the components to be installed TransWin32 The main program for displaying and managing the test reports Check ER The REA Verifier model REA Check ER is used PC Scan LD3 The REA Verifier model REA PC-Scan/LD3 is used ScanCheck 3n The REA Verifier model REA ScanCheck 3n is used MLV-2D The REA Verifier model REA MLV-2D is used VeriCube The REA Verifier model REA VeriCube is used The installation option ADB Client installs the REA article database software. The option ScanLink Assistant is an option for installing and using the ScanLink software for extended analysis and evaluation of ISO standardized data structures. These two software options should be installed only when these software options are purchased with the REA Verifier.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 30 of 119 Selecting the installation type gives you several installation options, depending on the desired type of installation. a. "install the programs for all users", all users of the computer can use the software. The configuration and adjustment data are stored by default in the directory C:\ProgramData. The users need read and write access to this directory. i. With activation of “Restore the backup of old configurations”, the following data will be restored for REA VeriCube: 1) TW32 settings (all items in menu >configure >options 2) Printer settings (the printer that was used, settings of the printer) 3) The verifiers that were connected in last session. 4) Serial number of measurements on one day 5) All settings of VeriCube, profiles, adjustment data b. “install the programs individually for each user”, only the respective user can use the software. The configuration and adjustment data are stored in the directory of the respective user under %AppData%. This means that each user then has his or her individual adjustment and configuration data. c. “Install the programs as Audit Trail System” (this is a chargeable option)": with this option all relevant actions are recorded and the data is stored in a secure area, the DataServer. This installation requires that the license is activated in VeriCube or that a license key is ordered from REA. Please also refer to the separate Audit Trail manual.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 31 of 119 Next, installation paths are displayed and can be modified, if desired. The programs are installed in the Programs (or Program Files) folder. The path C:\ProgramData is the file system for installation and programrelevant data, which normally remain invisible for the user. This path should be changed only when there are specific administrative reasons for that. The actual user data folder is always in the Documents section of the user or in the one for all users. The folder for saving the reports can be changed in the saving settings in TransWin32.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 32 of 119 At the end, the installation can be tested again. If at this point the installation is cancelled, this means that the old version has already been removed and the new one has not yet been installed. After clicking Install, the software is installed and the process is displayed in the window with a progress bar.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 33 of 119 When the installation was successful, this is shown as follows. Depending on the selected installation, the following icons can then be found on the desktop. In the actual release only the TransWin32 and maybe the REA ADB icon is there. The other two icons are not required because these programs are started and stopped automatically together with the TransWin32 program. With the icon TransWin32, the REA Verifier software is launched. "VeriCube Barcode Verifier" and "MLV-2D Barcode Verifier" are programs which are launched as device service (no window, only an icon in the task bar). Both are launched automatically at the start of TransWin32 and are also closed when TransWin32 is closed. REA ADB is the article database; it is used for management, recording and data import, which can be used with the REA Verifiers. The program is launched by the operator when needed. The article database (REA ADB icon) is optional and can only work with the REA Verifier when the program license is bought and also activated with the device.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 34 of 119 6.6 Mounting and exchanging the camera lens module Four different camera lens optic modules can be obtained for the testing of very small or very large codes. The optic modules are interchangeable and can be exchanged by the operator without the need for any tools. The different variants with focal length, minimum code size and field of view size are described in section 2.2. When changing the camera lens module, the device must be turned off. The knurled- head screw is unscrewed and the module can be removed. Picture of an camera lens module The black dust-protection cap on the lens must be removed prior to mounting. For each optic module type, one calibration dataset is saved. When a given camera lens module is used for the first time, the calibration must be performed prior to any measurement. ATTENTION: The lens of the optic module is optically measured and is preset. The alignment shall not be changed and the lens shall not be mounted on other electronics.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 35 of 119 7 Correct handling 7.1 General considerations The REA VeriCube is an optical measurement device with a camera and built-in lighting. The device should be lifted only by the recessed grips provided for this purpose. The camera module should never be used as a handle. Falls and impacts will damage the REA VeriCube Picture Recessed grip Picture of a built-in camera module The network cable is locked in the socket. The lock is loosened with a small plastic lever on the plug for removal. This socket/plug combination is relatively sensitive mechanically (robust industrial plugs were deliberately not used because they are very large and require expensive and special cables, which are hard to source). The cable should not be pulled without releasing the lock. The plug should not be subjected to any pulling, pressure or other impact. Any lateral strains lead to high risk of damage. The pulling strains can lead to damage or destruction of the cable and, additionally, of the socket installed in the device.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 36 of 119 7.2 Checklist for measuring The following points must always be observed for performing correct measurements: 1. The distance between the code and the device should vary only slightly. The depth of field is contingent on the small distance between the lens and the inspected area, limited to +/- 1 mm or 39,37 mils.. 2. The code should always be positioned centrally in the middle of the field of view. 3. The code should be aligned, as much as possible, in parallel or at an angle of 90° to the field of view in order to minimize any imprecisions due to staircase effects at the code edges. 4. The automatic determination of the position defines the measuring area for 2D codes and barcodes. The measuring area in the case of 2D codes is shown by a superimposed green square and in the case of barcodes, by red measurement lines. The square must surround the code in parallel to the code sides. The measurement lines must cross the bars of the code at an angle of 90°. If this is not the case, the measuring area must be determined manually. (See section 11.2) Picture: 2D code with manual ROI (region of interest = determining the measuring range) Picture: Barcode with manual determination of the ROI

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 37 of 119 5. When determining the measuring area manually, the parallel alignment or the 90° angle must be observed. When the barcodes are positioned diagonally in the field of view of the camera (when they are otherwise too wide), the measuring area must be determined at an angle of 90° with respect to the bars and not in parallel to the edges of the field of view. Picture: Manual ROI at a more slanted position of the code 6. It should not be measured in direct sunlight, under direct (spot) light rays or close to infrared sources (heat emitters). Ambient light will lead to changes in the measured results and the sunlight leads to unusable results 7. The test sample must be positioned flat on the measurement surface. If this is not observed, there are distortions in the measured picture level, which lead to incorrect measurement results. The risk is particularly high in foils and labels, which are processed as rolls. From the device position, the camera must always record the code in perpendicular and the lighting must always be at an angle of 45° (only the DPM measurements have particularities) 8. The transparent materials must always be measured on a flat, unchanging and impermeable black base (usually with a reflection of maximum 5%). When different measurement bases are used, the measurement results are also not comparable 9. The synthetic aperture should always be in the range of about 80% of the module width in order to obtain good decoded results. In case of 2D code measurements according to ISO/IEC 15415 or DPM (ISO/IEC TR 29158), the synthetic aperture is automatically determined 10.When there are several codes in the field of view and a code, which is not the one centered in the middle, is recorded, the codes that are not required must be covered. 11.The REA VeriCube must be regularly adjusted and has to be controlled with the help of test equipment monitoring for measurement accuracy (calibrated)(see sections 9 and 10)

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 38 of 119 12. Automatic recognition and decoding may recognize the codes incorrectly or not at all. In such a case, the operator must evaluate whether the result is valid or not and, if necessary, he should repeat the measurements with corrected settings or perform them several times. 8 Operating the device In some basic functions, the REA VeriCube can be operated with the device buttons The on/off button With this button, the device is turned on and off. The PoE power supply needs to communicate with the connected device, this results in some turn-on delay. It ends as soon as the left orange LED on the Ethernet socket of the device lights up. Prior to that, the device cannot be turned on. The Scan button A measurement is performed by observing the ROI, which is determined (manually or automatically) on the PC The F1 button The F1 button turns on the live picture display so that the code can be positioned. The live picture has a lower resolution than the measurement picture, and the brightness is adjusted automatically so that something becomes visible in the picture. This adjustment of the brightness can be completely different than the adjustment for the measurement with calibrated exposure settings.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 39 of 119 The F2 button The F2 button toggles between red and white light illumination. The F3 button The F3 button is provided for subsequent extension, e.g. a function, which can be assigned to the button by the operator through the TransWin32 software. The LEDs above the buttons have the following meaning: ON button LED The LED lights up permanently as soon as the device is ready for operation. SCAN button LED The LED shows the testing result. Red means "failed" and green means OK/ passed. F2 button LED The LED shows the type of light used for measurement. It is either white or red.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 40 of 119 9 Adjustment and Calibration of the REA VeriCube The terms “adjustment” and calibration are used in the sense of DIN 1319-1 and JCGM 200:2012. Calibration: The device measuring accuracy is checked against a known reference. For this process the device adjustment shall not be changed. Adjustment: The device settings (Exposure, white level, compensation of lens distortions) are changed until a specific result is achieved. The following calibration checks if the required measuring accuracy is achieved. The REA VeriCube must be calibrated in regular intervals of between 4 and 12 weeks. In the setting >configure >configure calibration and adjustment the validity period of the calibration can be entered from 1 to 90 days. (Up to and including TransWin32 version of CD9.16a (16607r) the validity of the adjustment was entered here. It had to be adjusted via the software within this entered period. Calibration with the REA calibration card was carried out in a further manual step, just like the calibration of additional test cards.) The REA VeriCube must necessarily be adjusted after installation of TransWin32 and first connection to the device. Afterwards it must only be adjusted if the calibration cannot be completed successfully, if a software update has been made or if you are working with another computer. In this case the menu item >Configure >Adjustment and calibration must be selected and the complete adjustment procedure as described in the next chapter must be performed. At the end, a calibration report is generated, which can also be saved as a pdf, printed and signed. If the calibration still fails after this, REA has to be contacted under email [email protected] , possibly there is a hardware error which has to be repaired. A new calibration is always necessary if the ambient and lighting conditions change significantly in the meantime or if the last calibration has expired. It can be activated, that the operator won’t be able to go on with evaluation if the calibration is not valid anymore. This setting can be found in >configure >evaluation:

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 41 of 119 If the function “Only evaluate images with valid adjustment and calibration” is not activated, the user only receives a warning when the calibration has expired. This information is then also printed on the test report. Note: this setting is saved individually in each profile The instructions for performing a correct measurement must be observed particularly closely during calibration (see section 7.2). The adjustment and calibration data of the REA VeriCube are, in contrast to the other REA Verifiers, saved in the PC – not on the device. Therefore, software installations on other PCs must always be adjusted again or the adjustment data must be imported from the first PC (see section 12.6) if the device is swapped to another PC. The REA calibration cards are used for adjustment and calibration. The following instructions for handling the calibration cards must be observed.  The calibration cards must not be dirty or scratched and their surface should not be touched.  The card for adjustment of the white level correction is protected in the delivered condition with a blue plastic foil. It must be removed prior to adjustment.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 42 of 119  If the card is damaged or contaminated, it must be replaced.  The date of the first use must be noted. This date determines the start of the lifespan of 2 years.  Before, the cards should not be stored unused for more than 2 years.  No calibration and adjustment can be performed with a photocopy of the original calibration card because as a result of the copying, the metrical and reflective properties change significantly. For the same reason, the calibration card shall not be laminated.  The calibration cards may be cleaned. The recommended cleaning agent is 3M Novec 71IPA  Adjustment and calibration must be performed in the same manner employed for measurement. If a mounted glass top plate is used for measurement, calibration and adjustment must also be performed with a mounted glass cover. When work is conducted without a glass top plate, calibration and adjustment shall also be executed without a glass top plate. The adjustment and calibration data are stored for each camera module depending on the respective s/n. For each camera module, adjustment and calibration must therefore be performed first. In the following they must be calibrated regularly. After changing to another optics module or after the respective calibration interval has expired, a new calibration is required. The calibration cards show a black reverse side. This is necessary in order to be able to perform calibration and adjustment without influence from the reflectance on the work table (the normal materials let the light penetrate). During the operation of an adjustment step, the device should not be moved. 9.1 Adjustment of REA VeriCube The device adjustment is initiated through the REA TransWin32 software. For this purpose, the menu item >configure, >Adjustment and calibration must be selected in TransWin32. Make sure that the adjustment does not take place directly after switching on the LEDs. You should start TransWin32, connect the device, make sure that the LEDs are

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 43 of 119 turned on and leaved them turned on for about 5 minutes, before starting the adjustment procedure. The REA VeriCube is delivered with a transparent plastic top plate, which covers the inside space of the camera, as well as with a glass top plate. The plastic top plate simply serves as dust protection during storage and transportation. The glass top plate is meant for measurements. Adjustments and measurements can be done with or without a top plate. Be aware that the measurement is only valid, if you measure in the same combination of verifier device and top plate, as you have adjusted the device. Adjustment is performed in three consecutive steps: 1. Level correction (level correction calibration card Art. No. 90031703) 2. Reflectance adjustment (calibration card Art. No. 90031702) 3. Scale adjustment (calibration card Art. No. 90031702) The adjustment status is shown after selecting the meue >configure >adjustment and calibration If an individual step is not executed correctly, there is a possibility to repeat this individual step separately. If an adjustment step was not successful, its old data are retained for this step. In this way, the device always remains functional. With the icon “Next”, it will be checked if there are valid target values for calibration available.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 44 of 119 If the target values are missing, the error message above will pop up and with the icon “OK”, you get into the input window.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 45 of 119 Explanation: Point 1 and point 4 must be taken from the calibration card: Point 2: here you enter the day when the card was unpacked and used for the first time. Point 3: the best before date is automatically calculated by the system according to the production date and the day of first use. Point 5: the 7 parameter values used for calibration must be transferred from the reference test report. Please refer to chapter 9.2.2 9.2.2Calibration for white light Attention: It is also possible to enter the parameters for several reference symbol sizes if a reference test report is available for them. For each reference symbol, however, all entries must be complete so that no error message will come up. The calibration of several symbols may be necessary if additionally e.g. an 8mm camera module or 50mm camera module is to be used and calibrated. The reference values entered for adjustment and calibration remain saved afterwards. However, it is essential to ensure that when using another calibration card (e.g. after a card has expired) the new values of the new calibration card are entered and afterwards an adjustment and calibration must be performed. After the input of the reference values is completed, an overview of the entered data appears after pressing the OK button.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 46 of 119 It is recommended to always make the adjustment for both types of illumination. This means that both red and white light should be checked. It is possible to do adjustment and calibration only for one type of illumination though. By selecting the icon the input window for the reference values appears again. This becomes necessary when a new calibration card is inserted. The "Next" button takes you to the menu for the adjustment:

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 47 of 119 9.1.1 Level correction For the level correction, the white card with article number 90031703 is used. Exception: The level adjustment with REA VeriCube UV The white card (90031703) is not suitable for UV light. Instead, a white area of the calibration card is used (90031702). The card is positioned so that a completely unprinted area of the map is in the field of view of REA VeriCube. The blue square in the image below shows the position that should be shown in the field of view.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 48 of 119 After the white card is placed on the REA VeriCube, the level correction is started by selecting the OK icon. Picture of a level correction card (original size 22 x 25 cm) Picture: The level correction card on the device The level correction corrects the uneven lighting of the measurement field (tolerances of the LEDs, construction, optics, etc.). Level correction adjustment can fail, can give a warning or is successful. If the highlight correction fails due to the fact that the adjustment data cannot be saved, it must be checked whether the Windows user also has access rights to the folder in which the adjustment data is saved. By default, these data are stored under a. Installation of the software for all users: C:\Programdata\REA Elektronik GmbH\Verifier\ MorpheusVeriCube b. Installation of the software for individual user: %APPDATA%\REA Elektronik GmbH\Verifier\MorpheusVeriCube In this folder, including subfolders, all users who perform an adjustment must have full access. The adjustment data are saved by: C:\Program Files (x86)\REA Elektronik GmbH\REA Verifier\MorpheusVeriCube\VeriCube_Control_PC.exe

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 49 of 119 If level correction fails or if there is a warning, the glass pane, the mirrow and the lens of the objective in the optic module must be cleaned (make sure you use optics cleaning cloth for glasses and lenses only, please see chapter 14). It may also be necessary to clean the level correction card with a slightly damp cloth and then to repeat level correction. If level correction does not function and a defect in the device can be excluded, a new level correction card must be provided. This can be checked with a simulated level correction using a new high-quality photographic paper. If this adjustment is accepted, the card must be replaced. If not, there is possibly a defect in the device and the device must be checked at the manufacturer or by an authorized service center and repaired if necessary. This does not apply to REA VeriCube IR. With this device the warning can only be avoided by making adjustments and subsequent measurements without a disc. However, it is also possible to continue working with this device despite the warning.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 50 of 119 9.1.2 Reflectance adjustment Please use calibration card (90031702) for this step. After level correction is finished, the menu item “reflectance adjustment” is automatically selected. However, it can be switched in between the different types of adjustment by selecting the appropriate icon. The device must be positioned with the help of the live video representation in such a way that the red cross hair is in the middle of the picture of the four reflectance fields, which are in the middle of the "Reflectance calibration field" field. The software automatically detects in which quadrant the bright field lies so that the direction is not relevant. Picture: Cross hair in the gray value field Then the Reflectance adjustment is started with the button.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 51 of 119 During the reflectance adjustment, a progress window appears. The adjustments for the red and white lighting are always performed one after the other and last for about 2-3 minutes. After finishing this process, the scale adjustment will automatically be selected: 9.1.3 Scale adjustment As a third step, the scale adjustment is performed. Picture: position of calibration card for scale adjustment With the help of the live video representation, the Data Matrix code, which is designated with Dnom = 0.5, is now positioned as precisely as possible in the middle of the cross hair and perpendicular to the image section. With OK button the scale adjustment can be started. Exception: Camera modules with 8mm and with 50mm focal length have to be adjusted and calibrated with the other symbol sizes:

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 52 of 119 Camera modules with 8mm focal length: Latest calibration cards contain a REA reference test report for the symbol Dnom = 0.75 and for Dnom = 0.5. For adjustment and calibration of the 8mm lens the symbol with Dnom = 0.75 should be used and thus the reference values from the test report of the 0.75 symbol should be transferred to the software. Nevertheless, it is also allowed to use Dnom = 0,5 for the 8mm camera module. Camera modules with 50mm focal length: For adjustment and calibration of the 50mm lens, the symbol with Dnom = 0.25 must be used and thus the reference values from the test report of the 0.25 symbol must be transferred to the software. When ordering a new calibration card, it is absolutely necessary to specify if a reference test report is required for the symbol Dnom = 0.25, because this is not part of the standard scope of delivery. The scale adjustment sets the pixel size automatically in such a way that exactly the known correct size of the calibration symbol appears in the measurement result. 9.2 REA VeriCube calibration Calibration (Test equipment monitoring) is a process with which the values measured by the device are compared with known reference results of a certified test code. The values measured by the device shall deviate from the reference values only within the specified tolerances. Calibration should be repeated in regular intervals (e.g. monthly). Calibration shows if the device is misaligned since the last calibration. If results show values out of tolerance all measurements since the last calibration needs to be checked and re- evaluated. The amount of deviation is taken into account. For extended calibration, the calibrated GS1-DataMatrix test card (Art. No. 90031704) and / or the calibrated test card for the EAN/UPC Code Verifier (Art. No. 90031705), which can be obtained as optional accessories, can be used in addition. The interval for calibration with these extended cards must be specified by the user. A detailed description can be found in chapter 9.2.4 9.2.1 Admissible device tolerances for calibration with red light The individual measurement values of the control measurements must be compared with the corresponding reference values. The requirements for the precision of the measurements are specified in the standards ISO/IEC 15426-2 for matrix code verifiers and ISO/IEC 15426-1 for barcode verifiers.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 53 of 119 The following data must be examined in order to make sure that the correct symbol with the settings for the test equipment monitoring has been used.

This report is created at the end of the manufacturing process. In case white light is used and white light shall also be calibrated, then the process described in chapter 9.2.2 is used too. The reference is also in this case the report created by using red light. This simplification is possible because black and white is supposed to provide the same reflectance values under red and white light. To prove that the method is working the performance has been checked by using calibrated reflectance standards (barium sulfate) which provide reflectance value for the visible light range from 400 to 700nm wavelength. The following data must be examined in order to make sure that the correct symbol with the settings for the test equipment monitoring has been used. Further measurement data and threshold values, which are shown, in addition, in the test report in the context, shall be ignored for this testing.

For better understanding, we report these parameters in %. So we do have a tolerance of +/-6 and +/-2. In the standard ISO/IEC 15426-2, Modulation is specified instead of contrast uniformity. This is also correct in the sense of the control, but difficult to follow. A footnote in ISO/IEC 15426-2 states that it is a per cent value. This per cent value refers to the Contrast Uniformity value specified for the test symbol 5 (see the card with the REA article number 90031704).

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 56 of 119 If the calibration fails, i.e. one or more parameters are outside the permissible tolerances, the "Adjustment and Calibration..." function must be performed. If the calibration still fails, the glass pane, mirror and objective lens must be cleaned and then "Adjustment and Calibration..." must be selected again. If the calibration still fails, please contact REA Support. By selecting the icon the last calibration report can be viewed again and if necessary a pdf can be created. Via the button "Next" the overview with reference values will pop up:

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 57 of 119 The reference values can be edited and modified by “Edit reference values” A test report with the reference results of REA is supplied with all calibration cards. The test reports with the reference results carries the following stamp: Picture: Stamp on the reference test report To avoid confusions, the certified calibration card has a serial number which is mentioned in the reference test report. Picture: User comment with the serial number of the calibration card The serial number and maybe also the verifier type indicated on the reference test report are different from those of the customer instrument. This is because the reference test reports are generated with a REA reference instrument. For calibration, the parameters listed in chapter 9.2.1 have to be checked. For 8mm camera modules, the code Dnom=0.75 should be used. (Dnom=0.5 is also possible though) For 12mm, 16mm, 25mm, 35mm camera modules, the code Dnom=0.50 must be used. For 50mm camera modules, the code Dnom=0.25 must be used. The values from the actual measurement report are compared with the target values from the reference test report. The deviations of the current measured values from the reference values must not exceed the maximum permissible instrument tolerances. This comparison is done automatically by calibration function.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 58 of 119 The parameters to be compared, which must also be entered as reference values in the calibration menu, are marked in the example report below: With the icon “Next”, the calibration routine is edited: The appropriate reference symbol (depending on the camera module that is to be calibrated) is positioned in the crosshairs at 90° and calibration is started with "OK":

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 59 of 119 A calibration protocol is then automatically created and opened: If both types of illumination have been adjusted and calibrated, an overview sheet is obtained and subsequently the results of the calibration for both types of illumination. If only one type of illumination is adjusted and calibrated, the overview sheet is not created as not necessary. The calibration report differs from the measurement report for quality measurement, as the tolerances from ISO/IEC 15426-2 are used as a basis here. The calibration report can now be exported to pdf, then printed, signed and filed via Windows if required.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 60 of 119 Calibration card 90031704 Calibration card 90031705 9.2.4 Calibration with extended calibration cards For this purpose, the extended calibration uses test cards, which are sold by REA and its authorized resellers, but are otherwise manufactured fully independently of REA and are measured with other reference devices (traceable back to national standards). Optional accessories for extended calibration are the calibrated GS1-DataMatrix test card (Art. No. 90031704) and / or the calibrated test card for the EAN/UPC Code Verifier (Art. No. 90031705. The interval for calibration with these extended cards must be specified by the user. Each symbol on the extended calibration card is optimized in print for the parameters listed on the front panel. For the extended calibration, only those parameters are compared that are specified directly on the calibration card. This means that the reference test reports supplied with the cards, which were measured with a high-resolution camera system, are not required for calibration.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 61 of 119 As an example, the contrast uniformity according to ISO/IEC 15426-2 is calibrated with a certain symbol with a dark module, completely surrounded by light modules ("dark widow"). This is found in symbols #6 and #9 and thus the contrast uniformity is only calibrated for #6 and #9. The Symbol Grade is not calibrated and may differ, because some symbol parameters are close to the threshold between two gradings. Permissible device tolerances from chapter 9.2.1 also apply with these cards. For most users the calibration with our calibration card is completely sufficient. The more reference codes are used for calibration, the safer it can be said that the measuring instrument actually measures accurately. However, it should also be considered that this requires more time for calibration. For this reason, we have listed various "safety levels" in the following as a guide to make it easier for the user to decide for himself how to calibrate. Additionally, it must be considered whether the built-in camera module is even suitable for measuring a code as small as the symbols #5, #10, #11 and #12 with X=0,200. A resolution of approx. 10 pixels per module is recommended.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 62 of 119 10 Synthetic aperture / measuring opening Under aperture or opening we normally understand the diaphragm opening of a camera lens. In this context, this is not the case. The diaphragm opening of the lens of the REA VeriCube has a fixed presetting from the plant, which achieves the best compromise between the maximum possible depth of field and the minimum possible diffraction effects. The synthetic aperture simulates the spot of light of a laser scanner. This takes place through mathematical filtering of the recorded measurement image. Depending on the aperture used in the code testing, the measurement results can vary. The synthetic aperture is always automatically set to 80% of the module width of the tested 2D matrix codes. Alternatively, the synthetic aperture can also be set manually The synthetic aperture forms an optical filter from the picture processing view, which causes certain blurring. This makes sense for suppressing the smaller and up to the smallest distortions in the picture, which are not relevant for verification. The symbols, which show many distortions, can disrupt the automatic determination of the synthetic aperture. When this is the case, the measurement results oscillate or there are invalid measurements. In this case, a manual determination of the synthetic aperture is recommended (under the condition that the symbols always have the same module size).

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 63 of 119 11 Execution of the measurements 11.1 Positioning of the device The REA VeriCube can be operated in different measuring positions. 11.1.1 Camera downwards In this mode, the device is positioned, for example, on a printed sheet or on another flat product with the camera pointing downwards. On a printed sheet, the device can be moved from code to code and the measurements are made in this position. In this case, the glass top plate must be removed, so that the cover is not contaminated or scratched by moving on the product or the printed sheet. As in this case the device largely covers the measurement area, the effect of the ambient lighting is negligible. Nevertheless, intensive light sources such as direct sunlight must be prevented. Picture: Camera downwards on the printed sheet

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 64 of 119 11.1.2 Camera upwards In this mode, the product is positioned on top of the measurement window of the device and the product is moved into the measurement field. For this type of measurement, the glass top plate should be used, so that the inside space of the camera (mirror, lens) is not contaminated. The ambient light influences the measurement and, therefore, the measurement area must be covered with the delivered black cover plate or with the black cover cloth in order to protect it from the ambient light. Picture: Camera upwards with the product on the glass top plate

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 65 of 119 11.1.3 Camera sideways The device stands either on its long side or on its short side. Plastic strips are inserted in the side walls, so that they are not scratched when the device is moved on the table. The codes to be measured are, for example, on cans, bottles or parts, which can be positioned in front of the device, so that the measurement conditions are maintained correctly. Since the long sides and the short side change the distance from the floor space, the respectively optimal position can be selected in this way. If this is not sufficient, the product or the REA VeriCube and the product can additionally be placed on a lifting table and thus the optimal measurement position can be set. Picture: Device positioned sideways with the product in front of the device

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 66 of 119 11.1.4 Turning the keyboard The keyboard of the device can be taken out and then replaced in an appropriate position with respect to the measurement position or the position of the device. Attention: The keyboard is connected to the main electronic using zero force connectors and a flat cable. Be careful when you pull out the keyboard. It is not allowed to pull at the cable! Loss of warranty, if you disconnect the flat cable from the connector! 11.1.5 Testing 3D parts It is possible to measure 3D parts (eg. automotive, electronics, machine building, and aerospace industry, etc.) if they shaped in irregular geometries. In some cases, these parts can be measured with one of the three or four standard positions. In other cases, this cannot be done. For such cases, a measurement fixture must be manufactured, which ensures that the code to be measured can be positioned correctly according to the handling instructions (angle, distance, shadows from components). Those parts are usually direct marked parts, marked by laser or other methods, for such DPM parts, the additional software license for DPM verification is needed (please see chapter 2.3). In simple cases the fitting of the glass top plate is used for a fixture. A part fitting instead of the glass top plate is manufactured and this holds a part exactly in the correct position. The advantage is the ease with which you can replace and modify such a fixture.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 67 of 119 11.2 Measuring process using the Windows software. A prerequisite for performing the measurement is the observation of the handling instructions (see section 7) as well as the selection of the desired position of the device (see section 11.1) The live video is turned on for the positioning. For this purpose, the F1 button on the device can be used or the symbol button for the live video on the PC screen. Start the live video Stop the live video The measurement area can be set in various ways. Most simply, only the red cross hair is displayed. The code is moved in the middle of the cross hair and then the measurement is started. To start the measurement, either the "Scan" button on the device or the "Evaluation" button in the Windows software can be used. Cross hair in the barcode Cross hair in the 2D code The evaluation is started with the "VERIFY" button. Pushing the evaluation button stops the live video and starts taking the measuring image in the full camera resolution. Afterwards, the evaluation is initiated. In a normal case, the symbology and the code type (1D or 2D) are recognized automatically. If the automatic recognition fails, the measurement area must be set manually.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 68 of 119 The icon with the blue square is the default for the measurement of a 2D code If the function is active, the three corners of the matrix code in the measuring image are clicked on by the mouse one after the other. This causes a blue square to appear, with which the measurement area (Region of Interest – ROI) for the code is determined. The thickness of the blue frame is not relevant for the measurement; it can be changed by turning the PC mouse wheel. Only the outside contour is taken into account. By changing the blue frame (the size, the precision with which the code is targeted), the stability of the evaluation can be improved in difficult measurement cases. If a barcode is being measured, then a red measurement area is positioned perpendicular to the barcode lines. The height of the bar determines the measurement area through the height of the barcode. The measuring width is determined automatically (up to Version 1.0.20.1) Version 1.0.20.1/13914r and later limmits the measuring width to the left and right position points.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 69 of 119 11.3 Automatic measurement mode If the automatic mode is activated, the measurement does not have to be started manually via the "Verify" button in TransWin32 or via the "Scan" button on the verifier. In this mode the user positions the code so that it is in the crosshairs and the software recognizes it. As soon as the software recognizes the code, this is represented by a green square or red bars: After a delay time, which is specified in the settings, the measurement is then automatically triggered. The result is then displayed and after a further specified waiting time, the live image is shown again so that the next sample can be positioned. In automatic mode, the test reports are always saved automatically in the file path set in menu >Configure >Options >File Saving "Default data path" and in TransWin32 Explorer only the last measurement is displayed ("single mode active" in the display options). In order not to disturb the automatic process, requests for job number, printing or saving are not displayed, even if this is selected in the settings. These settings with prompts apply only to manual operation. In the menu >Configure, >Others, >Automatic mode, the mode is activated and the time settings are made:

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 70 of 119 With the buttons you can pause and restart the automatic mode. pause: restart: 11.4 Automatic ROI The setting "Automatic recognition of the measurement area" is made with the icon: The 2D codes are framed automatically. In the case of barcodes, the measurement lines are determined automatically. In contrast to the mode with the cross hair, the measurement area is limited to the code size. This reduces the amount of data to be processed and increases working speed. 11.5 Mirror live image With this function the live image can be mirrored. This function can facilitate the positioning of the code in the crosshairs.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 71 of 119 11.6 Setting the brightness of the live image With some samples, the live image is very dark. To make it easier to position the code into the crosshair in these cases, you can manually adjust the brightness for the live image. This setting does not influence the measurement. 11.7 Recording the image The REA VeriCube can take an image without making an evaluation. Icon. Old icon New icon 11.8 Opening the image file With the icon Old icon New icon BMP, PNG and JPG image and several other formats can be processed. The loaded picture can be evaluated and thus a rough assessment of the code in the image can be made. The image data read in this way is not calibrated and no calibration data is included in such images. Similary, the test reports in TWS format or the images in XML format can be opened. The images can be saved again for documentation purposes, for example, as BMP or JPG files but because the previously set ROI as well as the calibration data are contained within the image, a full-value evaluation is possible afterwards.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 72 of 119 11.9 Saving the image file The images, which have been loaded and which have been obtained by measuring or by recording, can be saved (for analytical or documentation purposes) This takes place with this ICON Old icon New icon The images in PNG, BMP and JPG format can be used for documentation purposes only whilst the images which are saved in XML format contain the calibration data and can therefore, when opened again, provide a full-value testing evaluation. This is useful for comparing different software releases or for support purposes. 11.10 Static reflection measurement In a given measurement image (without evaluation, see section 11.7), a static reflection measurement is performed A red measurement point appears in the image

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 73 of 119 If the mouse pointer points to the measurement point, the point can be changed to the desired size with the help of the mouse wheel in order to obtain an adequate measurement section. With the help of the function, the reflection values can be determined in order to see in advance whether the contrast between the bright and dark areas (or the color selection between bright or dark) is sufficient. Depending on the type of the light (white or red), the measurement values can change. The displayed value of 26.3 is the reflection value that corresponds to the Rmin or Rmax reflection values. The X and Y data are the pixel positions in the image. D is the diameter of the simulated light point adjusted by the user. The usual synthetic apertures (the simulated light point diameter) are between 100µm (4mil) up to 500µm (20mil). This area is exceeded above or below in exceptional cases only. 11.11 Preset the measurement image size The measurement image can be presented considerably magnified or reduced in size. With the help of the buttons the display is changed. The piece of data in percentage shows the magnification. The value 45.8µm/pixel depends on the focal length of the lens used and is set by the adjustment. If the mouse pointer is positioned in the image, the image can be displayed smaller or larger by turning the mouse wheel. It can be magnified to such an extent that the individual pixels of the camera chip are visible and distinguishable. 11.12 Rotating the image Depending on the orientation of the REA VeriCube, the movement of the image does not follow what is maybe intuitively expected. For this reason, the image can be rotated with the help of the green arrow symbols until the movement of the image moves as expected.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 74 of 119 11.13 Behaviour of the software TransWin32 when locking the PC In the settings of the software you can specify how TransWin32 should behave, if during a session in TransWin32 the PC is locked or the screen saver is activated. In the menu >Configure >Options >General Settings it can now be selected, if the TransWin32 session should be closed automatically when the PC is locked or if the event should be ignored and thus the TransWin32 session remains: When a Windows user logs off, the TransWin32 software is always closed. If unsaved measurements were previously open, they are automatically saved in the default path from “file saving”. 11.14 View of the Reports Depending on the preset values in the options, the level of detail of the individual test reports displayed can be adjusted and changed based on the individual requirements. After a new installation of the software, the simple report will be displayed by default with every measurement, like shown in the following:

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 75 of 119 Screenshot1: simple report For the user who only performs measurements, it is easy to see whether the test result is good or bad without being loaded with too much information on the screen. There are two ways to change this initial view: 1. subsequent modification of the view to see more information about the measurement parameters 2. change the default setting, which view is always displayed after a measurement ref. 1: the selection of the appropriate view is done with these icons: The icon on the left shows the detailed graphical test report on the PC monitor (graphic view). This view is designed for qualified personnel with appropriate background knowledge and shows all test parameters in detail, partly in editable sub-windows.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 76 of 119 Screenshot2: Graphic view The second icon shows the evaluation comparable with a printout of the report (Text Report, long printout). Here the details are listed one after the other. Screenshot3: Text report The third icon shows a short view. This view provides all testing results in a compressed form, which can be used by the trained routine personnel. (Screenshot1) The fourth icon shows a report with GS1 format. This view is available for GS1 barcode symbologies only, not for 2D codes.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 77 of 119 Screenshot4: GS1-Report (only selectable subsequently) ref.2: In the settings (>Configure >Options >View), the default view can be set for single measurements and for multiple measurement. This view will be shown after each verification. The icons described before change the view on demand without changing the default setup.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 78 of 119 11.15 Details in the test reports In the graphical view of a given test report, the following icons are available: Binarization With this icon, everything in the image which is evaluated as dark is highlighted in yellow. This makes it possible to recognize the places where shadings or too bold / thin prints shift the thresholds to such an extent that the individual code elements become invisible Edge grid With the help of the edge grid, the reconstructed grid matrix is displayed. In this way, it can be recognized where the matrix cells lie and whether the symbol has been recognized correctly. The symbols with irregular brightness or with distortions (for example, through rounding) are subject to the risk that the matrix is inadequately recognized. With the help of this highlighting, it can be checked very quickly as to whether the recognized matrix corresponds to the actual code picture. If there are large deviations, this is an indication of invalid erroneous measurement, which must be repeated. Center grid In this grid representation, the lines cross in the middle of the matrix cells. Apart from that, the function and the meaning are the same as in the edge grid. The light margin (quiet zone)

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 79 of 119 The light margin (also called a white field, bright field or quiet zone) is indicated by the aid of this icon. This is in order to be able to easily recognize whether this area contains spots or other disorders which should not be there (homogeneous white in positive symbols or homogeneous black in negative symbols is necessary) Details measurement With this icon, the details measurement is turned on. A red point appears in the measured image, whose diameter shows the size of the synthetic aperture. The point can be moved with the mouse to different places of the code. The display then provides information about the code word number, bit number, reflection values and modulation values at the selected location.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 80 of 119 Matrix middle points The middle points of the matrix cells are highlighted with green dots Warnings With this button, all matrix cells (when active) are marked yellow, which, in relation to the modulation and the contrast measurement values, are close to the limit between two grades. The more such modules appear, the higher is the risk for a given measurement result to oscillate between two grades. Error indication All matrix cells which can be handled by the error correction are highlighted with red dots. This always occurs when a given matrix cell is recognized as dark instead of bright or vice versa. Depending on the symbology and code size, the error correction can recognize these errors and facilitate the correct decoding to a certain limit. When the capacity is exhausted, it is attempted to obtain a result with a non-standard decoding (error: Reference decode failed). If this does not aid the decoding, then no further decoding is possible. 12 Configuring the evaluation and symbologies In this section, the essential REA VeriCube configurations are described. This configuration is performed with the help of the Windows software TransWin32. The detailed description of TransWin32 is in a separate operating manual.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 81 of 119 12.1 Evaluation The presetting for the evaluation is done in the menu Configure / Evaluation. The important setting is "selected grade". For this purpose, the desired minimum quality in the area of the grade Sufficient (Grade 1), Satisfactory (Grade 2), Good (Grade 3) or Very good (Grade 4) is determined according to the respective test standard. A measurement result which has achieved, for example, Grade 2 – the grade Satisfactory, is thus evaluated in the previously selected Grade 1 as "Passed" and in the selected Grade 3 as "Failed". The barcode evaluation (1D) permits the choice between the ISO/IEC 15416 and ANSI X3.182 evaluation (this ANSI standard has subsequently been withdrawn. The evaluation and the measurement result do not change depending on the setting of ISO or ANSI. It is just the presentation of the measurement result that changes from numerical data to letters for the class (A instead of 4, B instead of 3, C instead of 2, D instead of 1 and F instead of 0). ISO/IEC 15416 is available in the version from year 2000 (integer grading) and alternatively in the version from 2016 (continuous grading with one decimal). The matrix code evaluation (2D) permits the choice between the method according to ISO/IEC 15415 for printed codes, for example on labels, or the DPM method according to ISO/IEC TR 29158, which is used, for example, for etched codes, dot peen marking or laser marked on metal (remember DPM software and/or model is optional). Note: The standard REA VeriCube has 45 °lighting from all four sides. This illumination type shall only be modified for DPM codes.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 82 of 119 Also the two transformation options shall be enabled for DPM codes only. This setting is not according to ISO/IEC 15415. Coordinate Transformation: Activating this function is useful for 2D codes applied to cylindrical parts. A distortion of the codes caused by the radius of the part is compensated by coordinate transformation. It is planned to use this function for checking in production, as inaccuracies in the alignment of the code may occur. The approval of printing layout/laser marking should be based on a measurement without activating the coordinate transformation. Reflectance Transformation: If enabled, bright spots on very glossy metal material will be ignored for verification. 12.2 Symbology selection The symbology selection determines which of the symbologies and with which respective properties they are verified. The selection and the properties determine the respective use.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 83 of 119 The left column shows the symbologies available in the software version. The right column shows the active symbology selection. To the right of this there are the properties of the respectively selected code. In this case, it is "GS1 Data Matrix ECC 200". This designation of the symbology is a short form for practical use, which, correctly formulated, would be "Data Matrix Code according to ISO/IEC 16022 with the error correction method ECC200 for the applications which are specified by the organization GS1-International". However, this is much too complicated. Only symbologies which have also been activated in the pre-settings can be tested and evaluated. All other non-activated symbologies are evaluated with a "Not decoded" error message and cannot be recognized and evaluated!

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 84 of 119 12.3 Lighting and aperture The lighting setting is in the menu Configure / Device. As light type (color of the lighting), red light with 660nm wavelength and white light with 4000°K can be selected. The normal setting for the direction of the lighting is the 45° quadripartite group. In certain cases, a single-sided lighting can be used. However, in the ISO/IEC 15415 mode, these cases are not calibrated and thus they can only be reasonably used in DPM mode. For testing purposes or for in-depth analyses, the adjustment can be turned off. As soon as the check mark next to "Use adjustment" is removed, the manual exposure setting is active. ATTENTION: Changing the manual exposure setting leads to changed and non-calibrated measurement results

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 85 of 119 The DPM lighting is performed according to a preset algorithm of ISO/IEC TR 29158 when "DPM Automatic Exposure" is turned on. When "DPM Automatic Exposure" is turned off, a manual exposure is active, which can also lead to measurement results which are different to the ones with the automatic exposure according to the ISO/IEC TR 29158 specification. The manual setting can be useful if the automatic is not set up as desired or leads to no decoding. The "Duration" entry field is the manual exposure setting. In addition, the aperture can also be changed here. In a normal case, the aperture will stay at the automatic setting. In this case, the aperture is set at 80% of the module width. For all application specifications the aperture is used according to the appropriate specification (e.g. GS1 specifications or PPN specifications for barcodes). The aperture entry takes place in the "mil" measurement unit. Mil means milli- inches. One inch is equal to 25.4 mm. Milli means 1/1000. Therefore, 1 mil is 25.4 µm (corresponds to 0.0254mm). The typical apertures, such as 6 mil or 10 mil, correspond to 0.15mm or 0.25 mm. The aperture is a subsequent formation of a light spot created by a laser. Since it is a subsequent formation, the aperture is called "synthetic aperture". The synthetic aperture is an image processing filtering whose purpose is to suppress the small, irrelevant disruptions in the code. Further details about the opening can be found in the REA training manual.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 86 of 119 12.4 Profile management The settings for evaluation, symbology selection, minimum quality and aperture setting are extensive and too complicated for most standard users. For this reason, settings can be stored in profiles. (Configure / Others / Manage profile) Up to 80 profiles can be defined. In practical use (e.g. production), a user selects the matching profile for a production job. Selection and activation of a profile sets a complete device configuration within one step.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 87 of 119 Profile selection is carried out using the icon in the icon bar. Along with the profile selection, password protection can also be used. With password protection, no settings can be changed. The task-related selection of the settings profile and the entry of the order number are excluded. 12.5 File Saving Options The test reports can be easily identified with the help of the entry of the order number. The order number is entered under Configure / Order number or by using the appropriate icon in the icon bar. This icon opens the window for inquiring the order number to appear automatically before or after any measurement, allowing the user to confirm or change the order number. The intention is to prevent users to forget the entry of new order numbers. The last order number that was in use will be shown in the text. This allows the user just to confirm with the OK button the last order number. Under Configure / Options / File Saving, it can be specified how the filename of the reports is to be given. For example, an order number or user name can be automatically added as a prefix in the file name of the test report. This function is valid for both manual and automatic saving. Additionally, a part of the decoded code content can be included into the report filename. For this mode the configuration “Configure / Options / Saving” needs to enable this function and to specify the part of the code content. The part of the code content defines the first digit and the data length. Counting of the first digit can be configured from the end or the beginning of the code (left to right or opposite).

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 88 of 119 In addition the configuration has a setting which ensures that each order number creates a subfolder in which reports are stored into. If a test report is converted to a PDF document through a PDF Writer, the generated file name (including the automatic numbering) is transferred to the PDF program. Thus, if the order number is used consistently, manual entry of file names is not necessary for saving and creating PDF documents. Saving measuring reports as PDF files can be configured to work in a background mode. This means that no user dialog is required to create the PDF files. All that is required is a third party PDF writer program. Measuring reports are in this case always available as PDF files without any action required to be done by the routine user. Attention: It is strongly recommended that all users have full access to the set directory for document storage. Restriction to read and write access may result in restrictions to some functions.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 89 of 119 12.6 Device data The calibration and service data can be saved by using Configure / Others / Collect device data. The calibration data can be re-imported on another PC with the TransWin32 installation for a REA VeriCube device. In this way, a new calibration can be avoided if one device is used alternately at different PCs. The device data also contains the settings The service data is required for support, bug fixing and device failure analysis. The import of the data can be executed with the "Configure / Others/ Import Vericube device data" menu item.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 90 of 119 12.7 User management 12.7.1 Simple user name The setting "TransWin32 User …" is a pure text replacement for the names of the respectively logged-in Windows users. If the user is not entered in the TransWin32 setting, the user name of the Windows user account appears in the printed test report. If there is an entry, this setting is always included as user in the test reports. In a next software version, this menu item will be moved into the "User and password" dialog box. 12.7.2 Simple password Independently of the simple user names, there is a simple password protection. The setting can be accessed under "Configure / Others / User and Password Setting". In the displayed setting, the simple password protection is active. In this mode, all settings, except for the profile selection, are inaccessible for the user without a password.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 91 of 119 12.7.3 Setting up the user management After an update of a device without user management or after the first installation, neither the user management nor the password protection is active. The user management must first be activated before becoming effective. It can be temporarily deactivated at any time or completely turned off by deleting all users (see below). The deactivation of the user management changes the following: A list of users with their passwords and their rights status is managed. The management of the list of users, the logging in and logging out of the users takes place centrally on the device. The respective user must authenticate himself with a password prior to using the device. There are two user types: normal users and administrators. The administrator has access and permission to do everything; the normal user can only do tasks which are possible without entering a password when the password protection is active (e.g. performing a measurement, selecting a profile, ...). The name of the logged-in user is stored in a log file. The following actions are stored in the log file:  Calibration  Creating a new user, deleting a user The user management can be applied through two alternative approaches:  User management through TransWin32 (only if the SW option is available) - User management through the service program (relevant for users of REA Check ER and REA ScanCheck 3 without a TransWin32 license) The actual user management dialog and also the subsequent work procedure are the same in both cases. The ways to access the user management dialog are different. In the TransWin32 software, the user management is accessed through the "Configure - > Others -> User and password setting ..." menu item. The service program is started either as a separate program or from TranWin32 under the "Tools" menu. In the service program, the "tab" "Profile and User Management" is selected. The desired device is selected with the search function of the device. With the "User Management..." button, the user dialog is accessed.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 92 of 119 At the first, the user dialog looks as follows: Picture: Selection of the setting "Protection of the device configuration with User ID and Password" When neither user nor password has been assigned, the dialog is confirmed with OK. A dialog appears with the password prompt of the preset administrator (Admin default). If a user has already been created, the dialog for user management can be started directly with the "User Management" button. The preset password is 739485.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 93 of 119 After logging in, the following dialog appears: If "Add user" is selected, the next dialog box pops up: A unique name is assigned as user name. The password is entered below. The user type selection list determines whether the new user is an "Administrator" or a "Normal User". The Administrator has all rights and permissions. The "Normal User" can essentially perform measurements and select predefined profiles.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 94 of 119 Attention: The first user that is entered must have administrator rights. As a result, the Admin default becomes invisible, i.e. it does not appear anymore in the list of the users. Afterwards, the user accounts for the operators can be created. The Admin default user disappears after the creation of further user accounts. Using "Delete Users", a users can be removed with the exception of the logged-in user. After the end of the creation of users, the administrator must log out. This is done in the main display with the Log Out button. If the password is no longer accessible (forgotten, misplaced), a three-time login with an incorrect password takes place. After this, the login can be attempted once more with the Admin default user. 12.7.4 User management during operation If the device is started with active user management, the user ID is always requested first (selection from the list of user names), together with the password belonging to it. Depending on the selection, the use as administrator or as normal user is possible. After logging in, the REA device is ready for measurement, or if an administrator has logged in, it is ready for measurement and configuration.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 95 of 119 Every user must log out after completing their tasks as automatic logout is not provided. A logged-in normal user can only change his own password in the user management. The dialog is accessed through the User management icon or through the menu Configure / Others / User and password setting The following input form appears. The data in parenthesis (here (ww) ) shows that the logged-in user has the name "ww".

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 96 of 119 When an administrator calls up the user management, the full dialog appears: 12.7.5 Transwin32 configuration protection The selection "Transwin32 configuration protection" just locks down settings of the Transwin32 software. Eg. print layout, data saving path and data export settings. Settings related to evaluation, measurement, reporting and calibration are not locked.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 97 of 119 13 Trouble shooting In this manual, only the device operation and the configuration are described. The testing results, their meaning and the search for errors in the case of poor results are not contained in this manual. The measurement results and their interpretation are introduced in the REA training document. Network error Prior to a further search for errors, the cables must be checked as well as the network sockets on the REA device. If the locking mechanism on the plug is broken, the contact is poor. If the socket on the device is defective, the contact may be poor. In this cases, a corresponding repair or replacement of the cable is necessary. Recommendation: Only network hardware supporting 1Gbit/s should be used. Unshielded (UTP) network cable types should not be used. Same addresses The PC and the REA Verifier device have identical network addresses (IP addresses). They must be different or there will be an IP address conflict. Several network cards If a given PC has several network cards, they must be separated with the help of a logical setting. This is done with the help of an IP mask and basic selection Example of a bad configuration Adapter 1 Address: 192.168.111.11 Mask: 255.255.255.0 Adapter 2 Address: 192.168.111.12 Mask: 255.255.255.0 Both network adapters (network cards, including WLAN) work in the same network. The REA Verifier on adapter 1 sends the data to the PC and the PC can send back the data through either adapter 1 or 2. If adapter 2 was chosen, the data no longer comes to the REA Verifier as it is connected to adapter 1. In this case, as an example, adapter 1 should be set to 192.168.113.11 and the REA device to 192.168.113.12. The Adaptor 2 setting remains unchanged. With this setting, adapters 1 and 2 are separated.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 98 of 119 Different logical networks If the REA testing device and the PC with the TransWin32 are in different networks, the connection does not function anymore. The device search is successful and then an error message follows. In this case, please follow the instructions in “temporary change of the IP address”. Example Device: Address: 192.168.1.12 Mask: 255.255.255.0 PC Address: 192.168.2.13 Mask: 255.255.255.0 Sometimes the communication is realized by using a network gateway in such cases. However this does not work with the VeriCube because the GigE Vision network protocol doesn’t support communications via gateways. Speed The REA VeriCube has a network connection with max. speed of 1 Gbit/s. If the REA device is connected directly to a PC with a 100Mbit/s network interface, the speed is automatically restricted to 100Mbit/s. If the REA device and the PC are connected through an Ethernet switch with a speed of 1Gbit/s and the PC can, as before, process max. 100Mbit/s., no automatic speed adaptation takes place because the Ethernet switch connects to the PC with 100Mbit/s and the REA VeriCube with 1Gb/s. In this case, the REA VeriCube sends the data 10 times faster than the PC network interface can process. Connection interruptions Connection interruptions can happen when the REA Verifier is integrated together with the PC in a company network. A high network load can lead to communication errors which are displayed as network errors or sensor errors. In this case, a second network card, which is used for the REA VeriCube only, should be installed in the PC. In some cases, problems might arise if the network adaptor is built with components of the manufacturer Realtek. In this case, a second network card, which works with the chip set of another manufacturer, can help. Version 1.0.20.1/13915r and later offers under Tools / Install or Uninstall VeriCube Network driver an installation of a network filter driver. This driver improves communication reliability. If both, the computer and the REA VeriCube are connected to an Ethernet switch with 100Mbit/s as highest speed communication errors can happen. In such an installation a 1Gbit/s Ethernet switch should be used.

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 99 of 119 Sensor error The correct positioning of the camera modules must be checked. Sometimes the sensor error is also reported if the network communication is not stable (see connection interruptions) Firewall The majority of computers use firewall software which, during day-to-day operation, protects the data from theft by outside parties or from the installation of undesired software from outside. This function is mandatory for all computers which are connected to the Internet. The REA VeriCube works through the network. The firewall must permit the data packages of the device to pass through. In particular, in very strictly administrated networks, the firewall is often set up so restrictively so that no communication is possible. The firewall must allow the GigE Vision network traffic based on UDP to pass. Temporary change of the IP address If a fixed IP has been assigned to REA VeriCube, but this is no longer permitted in the network, then the device can no longer be connected, but is still found. This will also happen, if the REA VeriCube and PC are in different logical networks. The current IP address of the REA VeriCube can be read after selecting “browse device” If the REA VeriCube network settings are set to DHCP ON, the address should be in the following range 169.254.xxx.xxx After selecting the device in the browse window above, the following message will come up To change the IP address temporarily, select “Ja” In the background, usually behind the TransWin window, a new window will start up:

REA VeriCube Operating Manual Version 2.16 – 11/2020 Page 100 of 119 tick on "show unreachable network devices" , select the appropriate unit and click on the icon on bottom left side "Set IP address" Now, an IP address can be set, that is reachable by your PC. But please be aware, that this IP will only be active in your VeriCube until next restart of the device!!! This means, don't turn off the Vericube, but connect it by TransWin32 and change the network settings of the VeriCube in the menue  Configure  Others  Device system
