A warning symbol means people might be injured if procedures are not followed. CAUTION: ! A caution symbol is used when equip- ment may be damaged if procedures are not followed. Below is a list of related publications you may need to refer to when using the scanners. • Publication No. 2755-921 Bar Code Basics Describes bar code symbologies, equipment, and typical applications. • Publication No. 2755-2.44 Product Data for the family of Visible Laser Diode Hand-Held Scanners Warning and Caution Symbols Related Publications

This chapter gives an overview of the scanner including: • Function of Scanner • Operating Modes • Scanner Setup Parameters • Scanner Accessories The scanner is a keyboard wedge interface that is capable of scanning, decoding, and transmitting bar code data to a host computer or terminal. As a keyboard wedge interface you can use the scanner with most manufacturer’s terminals. The scanner connects between the keyboard and display of the terminal. In this mode the scanner draws power directly from the terminal. The wedge translates scanned data so that it appears as if it was entered at the keyboard. When the wedge is transmitting scanned data, the computer ignores data entered at the keyboard. You configure the scanner for keyboard wedge mode by modifying scanner setup parameters. Parameters are selected based on the terminal type and the types of bar codes used in your application. The scanner is easily configured by scanning the appropriate bar code labels in Chapters 4 through 7 of this manual. When a configuration label is scanned, the scanner sends a 1 or 2 line acknowledgement message to your terminal display. Important: It is your responsibility to provide the appropriate application program on the host computer/terminal to receive and store the data. Chapter Objectives Function of Scanner

Chapter 2 2–2 The scanner functions in one of two operating modes: Hand-Held Mode or Autosense Mode. Hand-Held Mode In hand-held mode, you hold the scanner in your hand and press the trigger every time you want to scan a bar code symbol. Chapter 3 provides details on using the scanner in hand-held mode. Autosense Mode In this mode the scanner operates in an optional Autostand (Catalog No. 2755-NS2) for hands-free operation. The scanner uses a low level laser beam as an internal object sensor. When the scanner is placed in the stand it becomes immediately active for reading any bar code label presented to it. The scanner is triggered when a bar code label breaks the scan beam path (between the reflector on the stand and the scanner). You also have the option of removing the scanner from the stand and using it as a conventional hand-held scanner. The low level beam will not interfere with hand-held use of the scanner. When replaced in the stand the scanner reverts automatically to the Autosense mode. Note: Autosense mode can also be set up using a PHOTOSWITCH reflector. See Accessories. Operating Modes

Chapter 2 2–3 The built-in setup parameters of the scanner fall into four general categories: • Keyboard Wedge • General Setup • Message Format • Symbologies Each category controls parameters that relate to specific functions of scanner operations and its operation in wedge mode. Keyboard Wedge Parameters Parameters that configure the scanner to operate in keyboard wedge mode include: • Enable Wedge Mode • Select Terminal Type Chapter 4 shows how to enable the scanner to operate in wedge mode with a specific terminal type. General Setup Parameters General setup parameters are basic to the operation of the scanner. These parameters control: • System Status Display • Power Consumption • Beeper Operation • Capture Count • Spotter Beam • Autosense Mode General parameters are set by scanning bar code labels in Chapter 5. Setup Parameters

Chapter 2 2–4 Message Format Parameters Parameters that control the format and speed of messages transmitted to the host include: • Prefix • Suffix • Scanner Identifier • Code Identifier • Preamble • Postamble • Intercharacter Delay Message format parameters are enabled or disabled by scanning bar codes in Chapter 6. Symbology Parameters The scanner can be configured to read the following bar code symbologies: • Code 39 • UPC • EAN/JAN • Interleaved 2 of 5 • Standard 2 of 5 • Code 128 • Codabar Symbologies are selected based on the requirements of the application. You enable or disable symbologies by scanning bar codes in Chapter 7.

This chapter covers some basic topics on the operation and use of the scanner including: • Physical Description • LED Indicators • Safety Labels • Scanning Ranges • Operating Scanner • Beep • Operating Tips • Troubleshooting The scanners use a low power visible laser diode light source for non-contact scanning applications. The trigger in the handle of the scanner turns on the light beam. The beam exits the window on the front of the scanner. Trigger Cable Connection Scanning Window LED Indicators Note: If your scanner is enabled for Autosense mode, the internal object sensor is automatically triggered when bar codes are presented to it. Chapter Objectives Physical Description

Chapter 3 3–2 Light, reflected off the bar code symbols, passes back through the window and is detected by light sensors. When a label is read, the laser is automatically turned off until the next pull of the trigger. The laser beam looks like a narrow red line of light. It is actually a tiny spot of light traveling very fast. The laser spot moves across the bar code symbol at approximately 35 scans/second. The bar code is scanned many times in a short period of time. The rear of the scanner has two indicators that provide a visual indication of scanner operation. GOOD READ SCANNING Table 3.A defines the color and function of each LED indicator. Table 3.A LED Indicators LED Label Color Function GOOD READ Green The GOOD READ light momentarily turns on (and you will hear a beep) when a bar code symbol has been successfully decoded. SCANNING Yellow The SCANNING light turns on when the device is scanning. LED Indicators

Chapter 3 3–3 The scanners use a low power visible laser diode. As with any bright light source, such as the sun, you should avoid staring directly into the beam. Momentary exposure to a CDRH Class II laser is not known to be harmful. The following figure shows the location of all safety labels as they appear on the scanner. CAUTION: ! Use of controls, adjustments, or perform- ance of procedures other than those specified herein may result in hazardous visible light exposure. Safety Labels

Chapter 3 3–4 The scanners can read bar code labels at various distances depending on the bar code width (width of narrowest element in bar code, either bar or space). Table 3.B defines the scanning ranges for both the standard and long range scanner. Scanning ranges are listed for symbols with bar code widths from 6.0 mil to 55.0 mil (.15 mm to 1.40 mm). Table 3.B Scanning Ranges: Standard and Long Range Scanners Bar Code Width Standard Range (2755-G3-W) Long Range (2755-G6-W) 6.0 mil (.15 mm) 3.0 in - 5.0 in 7.6 cm - 12.7 cm N.A. 7.5 mil (.19 mm) 2.5 in - 7.5 in 6.4 cm - 19.0 cm N.A. 10.0 mil (.25 mm) 1.0 in - 10.0 in 2.5 cm - 25.4 cm N.A. 15.0 mil (.38 mm) 1.5 in - 14.0 in 3.8 cm - 35.6 cm 8.0 in - 22 in 20.3 cm - 55.9 cm 20.0 mil (.51 mm) 2.5 in - 18.0 in 6.4 cm - 45.7 cm 12 in - 36 in 30.5 cm - 91.4 cm 40.0 mil (1.02 mm) 9.0 in - 25.0 in 22.9 cm - 63.5 cm 23 in - 60 in 58.4 cm - 152.4 cm 55.0 mil (1.40 mm) 12.0 in - 30.0 in 30.5 cm - 76.2 cm 23 in - 66 in 58.4 cm - 167.6 cm Figure 3.1 illustrates the scanning ranges in graphic form.

Chapter 3 3–6 Follow these basic steps to operate scanner. 1. Check Before using the scanner, check all cable connections to make sure they are secure. Chapter 4 defines the wedge interface connections for the scanner. 2. Test Aim the scanner at the work surface and press the trigger. You should see the red beam on the work surface, and the SCAN- NING indicator on the back of the unit should be on. 2. Scan Aim the scanner at the bar code and press the trigger. Adjust the scanner position so the beam is centered on the bar code and overlaps it on both sides. When the scanner has read the symbol: • You will hear a beep and/or ... • The GOOD READ light will turn on momentarily. • The red beam will turn off. If you fail to scan, see the Trouble- shooting section. Operating Scanner

Chapter 3 3–7 When scanning a bar code symbol, listen for one short, high tone. It means the bar code has been decoded successfully. Hold at an Angle Do not hold the scanner directly over the bar code. In this position light can bounce back into the scanner and prevent decoding. Angle the scanner slightly. Scan the Entire Symbol • Move the scanner so the beam crosses every bar and space on the symbol. • The larger the symbol the farther away you should hold the scanner. • Hold the scanner closer for symbols with bars that are close together. • If you have difficulty reading a label hold the scanner beyond the recommended range in Figure 3.B and then move the scanner closer. Beep Operating Tips RIGHT WRONG

Chapter 3 3–8 This section provides a list of things to check if you are having problems scanning. Note: Scanning problems are most often caused by poor quality bar code symbols. If scanning problems arise test your bar code system using the high quality bar code test symbols supplied in Appendix A. • Make sure the scanner is configured to read the the type of bar codes you are trying to scan. • Check if the bar code symbol is worn or damaged. • Verify that you are holding the scanner at an angle. • Make sure the beam crosses every bar and space on the symbol. • Check for loose cable connections. • Check that there is power to the scanner and the host computer or terminal. If you perform these checks and the symbol still does not scan, contact your Allen-Bradley representative. Troubleshooting

• Installing the Wedge Interface • Enabling Wedge Mode • Selecting Terminal Type • Scanner Configuration Guidelines • Scanner Default Settings Figure 4.1 shows the basic connections for installing the scanner as a keyboard wedge interface. The installation uses two cables: the scanner interface cable and the wedge interface cable. Cables for the different terminal types are listed in Table 2.A.

Failure to do this could result in damage to the scanner. CAUTION: ! To remove the interface cable, follow these steps. 1. Turn power to computer/terminal off. 2. Disconnect optional power supply from AC power source. 3. Disconnect scanner from wedge interface cable. 4. Insert a straightened paper clip into the cable release hole as shown in Figure 4.3. 5. Press down firmly on the paper clip to release the retainer and gently pull the connector out of the scanner. Figure 4.3 Removing Interface Cable Cable Release Hole

The wedge interface cable connects the scanner to the terminal keyboard and the terminal. You select a wedge interface cable based on the the terminal you are using. The available cables are listed in Table 2.A. The wedge interface cable has a connector housing and a ”Y” cable. The housing contains 1 or 2 plug-in sockets for the scanner and an optional power supply. The two legs of the ”Y” cable connect to the terminal keyboard and the terminal. Do not connect scanner to terminal until power to the terminal is off. Failure to do this could result in damage to the scanner. CAUTION: ! To connect the wedge interface cable: 1. Turn off power to the computer/terminal to which the scanner will be connected. 2. Plug the DB9 squeeze-to-release connector of the scanner interface cable into the connector housing of the wedge interface cable. 3. Unplug the keyboard from the terminal and replug the keyboard into the short leg of the ”Y” cable. 4. Plug the remaining long leg of the ”Y” cable into the terminal where the keyboard was connected. 5. Arrange the fully connected unit so that all cables run freely.

Some terminal interfaces require an external power supply. One end connects to a standard AC receptacle supplying the appropriate voltage level. The other end plugs into a receptacle located on the housing connector of the wedge interface cable. The Catalog No. 2755-PW1 Power Supply has the following polarity: CAUTION: ! + If using another power supply, the polarity must be the same. +5 V Ground To install the power supply: 1. Power to the terminal must be turned off. Do not connect power supply until the terminal is turned off. Failure to follow this caution could result in damage to the scanner or terminal. CAUTION: ! 2. Plug the circular connector of the power supply into the receptacle on the housing connector of the wedge interface cable. 3. Plug the power supply into a standard AC power source. Terminal Power Up Sequence Turn on the power to the terminal to which the scanner is connected. The unit will issue a series of beeps which are intentional and indicate that the terminal/keyboard power-on reset routines have been completed.

VT420, VT1000 You have now completed the process of installing and configuring the scanner to operate in wedge mode. The rest of the manual covers additional parameters that can be set for the scanner and your application. Review the configuration guidelines and factory default settings in the following sections to determine if changes are required.

certain scanner operating parameters. The host computer/terminal and the types of bar codes that will be encountered will determine which parameters should be enabled or disabled. Follow three basic steps to configure your scanner: 1. Review the rest of the manual to familiarize yourself with each group of scanner parameters. 2. Review the requirements of your application This will enable you to determine if the factory defaults must be changed. 3. Enable or disable the relevant parameters by scanning the bar codes in Chapters 4 through 7. The section that follows describes this process. All configuration bar code labels in this manual are Code 128, Character Set B. Scanning Menu Labels The scanner does not have a distinct configuration mode. Instead, it automatically recognizes and reacts to labels you scan. You do not scan an enter or exit label to begin or exit configuration mode. Most parameters are set by scanning one label. For example, assume your application uses Codabar labels. By default, this symbology is disabled. To select the Codabar symbology, locate the Codabar menu in Chapter 7 and scan the label to the left of Enable Codabar. The correct label is shown below. VB Enable Codabar A successful scan is indicated by two short-high beeps. An unsuccessful scan produces no beeps and requires you to rescan the Codabar label. Most parameters are modified in this way. When you are finished with modifications you can resume normal bar code scanning. Scanner Configuration Guidelines

sure the scanner beam illuminates only one symbol at a time. The layout of this manual minimizes the accidental scanning of multiple labels. Some parameters require that you scan multiple labels to modify a setting. An example is the Intercharacter Delay parameter. To set the intercharacter delay to 5 milliseconds (msec): 1. Scan the Intercharacter Delay (GB) label and listen for one short beep. GB Intercharacter Delay=xx msec + The dotted boxes to the right of the label indicate that you must scan two additional labels; one for the digit 0 and the second for the digit 5. 2. After the beep, scan the bar code beside 0 in Appendix B, and listen for one short-high beep. 3. Scan the bar code beside 5 in Appendix B and listen for two short beeps. The two beeps indicate that you scanned the last parameter argument. If you scan the Intercharacter Delay (GB) label and then scan a normal data label (instead of 0 and 5), a normal tone is emitted in response to the data label, and the programming command is ignored. No exit code is required to resume normal operations. Note: Any parameter that requires multiple scans will display dotted boxes to the right of the primary label. The number of dotted boxes indicates the number of additional labels to be scanned.

Chapter 5 5–3 You can select one of two power consumption modes for the scanner. Option @A supplies full power to the scanner at all times. Option @B allows the scanner to revert to standby mode after a successful read. This mode is a power conservation feature whereby the scanner uses extremely low power (microwatts) from the host terminal. To supply full power to the scanner at all times, scan label @A. @A Enable Continuous Full Power * Note: The scanner automatically uses full power when configured to operate in Autosense mode. To allow the scanner to revert to standby mode after a successful read, scan label @B. @B Enable Standby Power Power Consumption

Chapter 5 5–4 To disable or set the volume of the beeper, scan the appropriate option below. AA Beeper Off AB Beeper On; Volume Low AC Beeper On; Volume Medium Beeper On; Volume Loud * AD Beeper Operation

Chapter 5 5–5 Capture Count determines the number of successful, identical decodes that must occur for a valid read. You can use the capture count to enhance the security of the bar code reader. Option BC sets the capture count to 1 which requires one successful decode. BC Capture Count = 1 * Scan option BD to set the capture count to 2. Two identical decodes must occur for a valid read. BD Capture Count = 2 Because the laser scans a label many times a second, you will notice little or no change in the speed of the decode. Capture Count

Chapter 5 5–6 You can enable the scanner to use a spotter beam which helps when aiming the scanner. Each time you press the trigger, the scanner generates a bright laser spot for a fixed duration, after which the scanner beam is activated. The spotter beam is recommended for long range applications. Scanning label NP disables the spotter beam. Hold the trigger for two seconds after scanning. Disable Spotter Beam * NP To enable the spotter beam, scan label NQ, then scan a digit from 0 – 9 (Appendix B), holding the trigger for two seconds after scanning the digit. Each digit enables the spotter beam for a specified duration as shown in the table below. For example, to enable the spotter beam for 200 milliseconds, scan the NQ label, then scan code 3 in Appendix B. NQ Enable Spotter Beam=xx msec + This Digit Enables Spotter Beam for: 0

  Note: Spotter Beam and Autosense Mode are mutually exclusive parameters. Only one of these parameters can be enabled at a time. Spotter Beam

Chapter 5 5–7 In Autosense mode, the scanner has an internal object sensor allowing you to operate the scanner in an optional Autostand (Catalog No. 2755-NS2) for hands-free operation. When the scanner is placed in the Autostand it becomes immediately active for reading any bar code label presented to it. The scanner is triggered when a bar code label breaks the scan beam path between the reflective label on the stand and the scanner. To activate Autosense mode, scan the Enable Autostand (NO) label. You must hold the trigger down for two seconds after scanning the label. NO Enable Autosense Mode The scanner will respond by emitting a continuous, low level, red beam of light. Note: The scanner is automatically configured to use full power (not standby power) in Autosense mode. For details on how to set up the scanner to operate in the optional Autostand, see Appendix C. To deactivate Autosense mode, scan the Disable Autostand symbol (NN). You must hold the trigger down for two seconds after scanning the label. NN Disable Autosense Mode * Note: Spotter Beam and Autosense Mode are mutually exclusive parameters. Only one of these parameters can be enabled at a time. Autosense Mode

This chapter defines parameters that control the format of transmitted bar code messages including: • Prefix and Suffix • Scanner Identifier • Code Identifier • Preamble and Postamble In addition to these parameters, you can program an intercharacter delay to prevent data overruns with your host computer/terminal or wedge. A message transmitted from the scanner upon a successful decode has the following format: Prefix Scanner Identifier Code Identifier Data Postamble Suffix Preamble Some of these message parameters may not be required or may vary from one host system to another. You select parameters based on the requirements of your application and the host system. To select message parameters, you scan the appropriate bar code labels in each section. Note: Throughout this chapter default settings for parameters are flagged by an asterisk (*). Chapter Objectives Message Format

Chapter 6 6–2 A prefix is a subset of the preamble normally formatted to some industry standard. It is represented by a specific ASCII code. An example of a prefix is the STX (Start of Transmission) code. Scan the appropriate prefix label. IA Prefix=None * IB Prefix=STX Pref IC Prefix=SOH Prefix

Chapter 6 6–3 A suffix is a subset of the postamble. Like the prefix, it is normally assigned to a specific ASCII code. Examples of suffixes are CR (Carriage Return) and LF (Line Feed). Scan the suffix appropriate for your application. MA Suffix=None * MB Suffix=ETX Suffix=CR MC MD Suffix=LF ME Suffix=HT MF Suffix=CR and LF Suffix

Chapter 6 6–4 Scanner ID characters are used to identify individual scanners when more than one scanner is interfaced with the host system. Options available are none (Disabled) or digits 01 through 99. Scanning label JA disables the scanner identifier. JA Disable Scanner Identifier * To enter a scanner ID, scan label JB and then two separate digits from Appendix B. The ID characters cannot exceed 99. JB Enable Scanner Identifier + plus two characters For example, to enter a scanner ID of 01, scan the JB label, then scan codes 0 and 1 in Appendix B. Scanner Identifier

Chapter 6 6–5 A single-character code identifier may optionally be transmitted with a message. This option allows the host computer to identify the type of bar code scanned, as well as the encoded information. Scan option FA to disable the code identifier. FA Disable Code Identifier * Scan option FB to enable the code identifier. FB Enable Code Identifier Table 6.A shows the code identifier character assignments. Table 6.A Code Identifier Characters Symbology Code Identifier Code 39 a Interleaved 2 of 5 b Standard 2 of 5 c UPC/EAN/JAN d Code 128 f Codabar h Code Identifier

Chapter 6 6–6 Preambles and postambles consist of up to four ASCII characters. Each ASCII character is encoded as two hexadecimal characters. Use Table 6.B, Hexadecimal Conversion Table, to look up the hexadecimal equivalent. To use the conversion table: 1. Find each ASCII character in the table and locate the corresponding bold hexadecimal equivalent character in the top row and the left column of the table. For example, the ASCII character ”Q” is represented by the hexadecimal numbers 5 (top) and 1 (left). 2. Scan the bar code symbols that correspond to the hexadecimal equivalent characters. First scan the bar code symbol that corresponds to the bold hex character at the top. Then scan the bar code symbol that corresponds to the bold hex character at the left. For example, for the ASCII character ”Q”, first scan the bar code symbol labeled 5, then scan the bar code symbol labeled 1. If your preamble or postamble contains an ”N”, first scan 4 and then E. 3. Repeat this procedure for each ASCII character you want to enter. Note: If you select a preamble or postamble you must scan four ASCII characters, even if the preamble or postamble is less than four characters in length. Do this by scanning null (NUL) characters for the additional characters. For example, if your preamble is ”AB” (in ASCII code), enter A, B, and two null characters by scanning the hexadecimal characters 4,1 4,2 0,0 0,0. Because each ASCII character is represented by two hexadecimal characters, you need eight scans. Preamble or Postamble

Chapter 6 6–7 A preamble is a string of characters that prefixes a message that is transmitted to the host. The preamble may be used to identify the scanner that sent the message. The maximum preamble length is four ASCII characters. KA Preamble=None * To enter a preamble, scan the KB label, then refer to Table 6.B to enter the four ASCII characters. The procedure on the previous page explains how to enter preamble characters. KB Preamble = 4 ASCII (8 Hex) characters + A postamble is similar to a preamble, except it is appended to the message which is transmitted to the host. Its maximum length is four ASCII characters. LA Postamble=None * To enter a postamble, scan the LB label, then refer to Table 6.B to enter the four ASCII characters. The procedure on the previous page explains how to enter preamble characters. LB Postamble = 4 ASCII (8 Hex) Characters + Preamble Postamble

Chapter 6 6–10 Certain terminals and computers require an intercharacter delay to simulate the effects of keystroke delays. Selecting an intercharacter delay causes the characters to be sent at the slower rate required by the device to which you are interfacing. Scanning label GA disables intercharacter delay. GA No Intercharacter Delay * To set Intercharacter Delay to a value other than zero, scan label GB, then two separate digits from Appendix B. The intercharacter delay cannot exceed 31 milliseconds. GB Intercharacter Delay=xx msec + For example, to set the delay to 15 milliseconds, scan the GB label, then scan codes 1 and 5 in Appendix B. Intercharacter Delay

Use the following labels to insure that your scanner is functioning properly. The only label the long range scanner can read below is the Interleaved 2-of-5 (15 mil) label.

using the optional Autostand follow the steps below while referring to Figure C.1. 1. Enable the scanner to operate in Autosense mode by scanning the Enable Autosense (NO) label in Chapter 5. 2. Attach the Stand Riser to the Stand Base using two of the supplied #6-32 thumb screws. 3. Attach the Scanner Holder to the top of the Stand Riser using the other two #6-32 thumb screws. 4. Verify that the reflective label is affixed to the Stand Base. 5. Place the scanner in the stand as shown in Figure C.1. 6. Check that the red beam of light is aimed at the reflective label on the stand. The Autostand is now ready to read bar code labels presented to it. While the scanner is activated in Autosense mode you are able to remove the scanner from its holder and use it for hand-held applications. When the scanner is removed from the Autostand the scanning beam is turned on automatically to read a bar code label. If the scanner does not see a label the scanning beam will turn off after four seconds. Scanning is re-initiated by manually pulling the trigger. The scanner can then be placed into the stand once again and it will function in Autosense mode.

#6-32 Thumb Screws Stand Riser Label 1 Important: When the scanner is to be powered from a battery such as in a hand-held terminal, you should disable Autosense mode. In this application, you may need to use the power conservation mode of the scanner when drawing power from a battery. Auto- sense mode will function only in full power mode. 1 Reflective tape is supplied with the autostand. Additional reflective tape is available by ordering Catalog No. 2755-NT1.

information for your scanner. You may need to clean the window of the scanner. Carefully clean the window by first removing loose particles of dirt with clean air. Then use a soft, lint free cloth moistened with an optical quality cleaning fluid for plastic lenses and wipe the window in a single direction (don’t wipe cloth back and forth across window). Do not leave streaks. CAUTION: ! Do not use abrasive material or sol- vents (e.g., alcohol or acetone) on the window. These items may damage the window or finish on the scanner. WARNING: ! The scanner has no serviceable parts. Do not open the housing of the scanner. Periodically inspect the cable on the scanner for wear and other signs of damage. A worn or damaged cable may interfere with the operation of the scanner. Contact your Allen-Bradley representative to order replacement cables. Cleaning Window Inspecting Cables

Manufacturers. alphanumeric: The character set containing letters, numbers, punctuation marks, and symbols. ASCII: American Standard Code for Information Interchange. It is a seven-bit code with an optional parity bit used to represent alphanumerics, punctuation marks, and control codes. bar: The dark element of a printed symbol. bar code: The parallel bars and spaces found in a bar code symbol. bar code density: The number of characters which can be represented in a linear inch. bar code label: A label that carries a bar code and is suitable to be affixed to an article. bar code symbol: A group of parallel bars that represent a character or group of characters whose spacing is determined by a specific set of rules. In most cases, human readable characters are printed below the bars. bar length: The bar dimension perpendicular to the bar width. bar width: The thickness of a bar measured from the edge closest to the symbol’s start character to the trailing edge of the same bar. character: A single group of bars and spaces representing an individual number, letter or punctuation mark. A graphic shape representing a letter, number or symbol. check digit: A digit included within a symbol whose value is based mathematically on other characters included in the symbol. It is used to mathematically check the accuracy of a symbol.

precedes the start character of a symbol and follows the stop character. Codabar: A numeric symbology consisting of 16 data characters and 4 start/stop characters. Codabar is primarily used by the medical community. Code 128: A symbology representing the full 128 ASCII character set. Numeric data may be represented in a double density mode where two digits are represented by one character. Code 39: An alphanumeric symbology recognized by most nations, widely used in the manufacturing industry. code type: See symbology. decode: The process of translating a bar code into data characters using a specific set of rules for each symbology. decoder: A device used to decode, or make usable, a digital or analog signal transmitted from a scanning device. The scanner contains a decoder. EAN: Acronym for European Article Numbering system, the international standard bar code for retail food packages. element: Dimensionally the narrowest width in a character, bar or space. encoded area: The total linear dimension consisting of all the characters of a code pattern, including start/stop characters and data. guard bars: Bars at the ends and center of a UPC and EAN symbol. They ensure a complete scan of the bar code. hex: Abbreviated form of the word hexadecimal. See hexadecimal. hexadecimal: A base-16 numbering system that uses the symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F.

manner that its overall length dimension is parallel to the horizon. The bars look like a picket fence. Interleaved 2 of 5: A symbology in which characters are paired together using bars to represent odd number char- acters and spaces to represent even number characters. ladder orientation: See vertical bar code. modulus 43 check character: Used in Code 39 for data security in addition to the builtin self-checking characters. The check-character is the modulus 43 sum of all of the character values in a given message and is the last character in the code. orientation: The alignment of bars and spaces to the scanner. Often referred to as vertical (ladder) or horizontal (picket fence). parity bit: An additional non-data bit attached to a binary word to provide a check of the data integrity by making the sum of the number of ones in a word always even or odd. picket fence code: See horizontal bar code. scan: The search for a symbol or marks which are to be optically recognized. scan area: The area intended to contain a bar code symbol. scanner: A device that optically scans bar code symbols and converts the optical information into digital or analog form and sends it to a decoder. self-checking: A bar code or symbol using a checking algorithm which can be applied to each character to guard against undetected errors. Codes that are not self-checking may employ a check digit or other redundancy in addition to the data message. space: The lighter element of a bar code formed by the background between bars.

the scanner with information on how the code is bounded and its orientation. The start character is normally at the left end of a horizontal code and adjacent to the most significant character. The stop character is normally at the end of a horizontal code and adjacent to the least significant character. symbology: The conventions, or rules, which govern the formation of characters and strings in bar codes. The language of the bar code symbol. symbol density: The number of characters per linear inch. symbol length: The length of the symbol measured from the beginning of the quiet area adjacent to the start character to the end of the quiet area adjacent to a stop character. UPC: Acronym for Universal Product Code. The standard bar code for retail food packages in the United States. vertical bar code: A code pattern in which the overall coded area from start to stop is perpendicular to the horizon. The individual bars appear as rungs of a ladder. wedge interface: A programmable device with resident memory capable of translating scanned bar code data so that it appears that the data was manually entered on a keyboard.
