1. GENERAL INFORMATION Dear customer, thank you very much for choosing our product. In fol- lowing, we will introduce you to what to observe while starting up and using this product. Should you encounter any unexpected problems dur- ing use, please do not hesitate to contact us.

2.1 Assembly of the Display Take out the display, the foot and the socket neck from the package. Insert the metallic rectangle of the socket neck into the matching conduction on the display case (near the USB imprint). Fixate the socket neck by tightening the round washer, which is located directly in front of the metallic rectan- gle. Now insert the socket neck into the foot and tighten it with the provided screws.

If you wish to operate the display with a Raspberry Pi , you can use the mounting platform provided for this purpose. Remove the provided mounting platform and attach your Raspberry Pi onto it. After you have fixated your Raspberry Pi, place the mounting plate on the back of the display and mount it to it (screw holes 9 - Vesa). The display is now completely assembled and should correspond to the following picture.

First, plug the power supply into the display. Then, con- nect the display with the device, which should be used, using the HDMI cable. To use the Touch functions as well, the display must also be connected with the device to be used with the pro- vided USB cable. ! Caution! Do not confuse the USB ports! You have to use the port with the imprint "touch" on the display to be able to use the touch functions.

3.1 Installation of software Install the LCD image on your SD card with the help of the „Win32 Disk Imager“-program, which you can find as preinstalled Raspbian system for your Raspberry Pi as download by the following link: https://joy-it.net/de/products/RB-LCD10-2 3.2 Manual Installation & Calibration (experienced user) -Usage with a Raspberry Pi 4: For the usage with a Raspberry Pi 4, a setting in „/boot/ config.txt“ must be edited. For this, please enter the sudo nano /boot/config.txt 1. Choose Image 2. Choose Device 3. Write SD card with image

lowing command: dtoverlay=vc4-fkms-v3d. This should look like the following: If you do not want to use our prepared Image or inte- grate the display into an existing system, you can also install the display manually, of course. First, connect the both devices with the provided HDMI cable. Connect both the display and the Raspberry Pi with the matching power supplies. [pi4] # Enable DRM VC4 V3D driver on top of the dispmanx display stack # #dtoverlay=vc4-fkms-v3d max_framebuffers=2 <- This setting has to be commented out with # ! Caution! When starting the display for the first time, the Raspberry Pi has to be started AFTER the Display! Otherwise, the transmission of pic- ture data will not function.

is started with the Raspberry Pi, the „config.txt“-file has to be edited first. Open it with the following command: Now enter the following lines at the end of the file. Afterwards, you can save the file using the key combina- tion CTRL+O and exit the file with the combination CTRL+X. Now install the Touchscreen driver with the following command: To ensure, that the installed drivers are always initial- ised after the existing drivers, please copy the configu- ration file with the following command (please write the command in one line !): Next, the calibration tool can be installed and started with the following command: sudo nano /boot/config.txt hdmi_force_hotplug=1 hdmi_group=2 hdmi_mode=27 sudo cp /usr/share/X11/xorg.conf.d/10- evdev.conf /usr/share/X11/xorg.conf.d/45- evdev.conf sudo apt-get install xserver-xorg-input-evdev sudo apt-get install xinput-calibrator

Before your can start the calibration tool, you have to create the file for the calibration settings (please write the command in one line !): Now enter the following settings in this file: Restart your Raspberry Pi then: Now you can start the calibration tool with the follow- ing command (please write the command in one line !): The display will now show four consecuting points that you will have to press. After that, four calibration val- ues will be outputted to you, which you must enter in sudo reboot sudo nano /usr/share/X11/xorg.conf.d/99- calibration.conf sudo reboot Section "InputClass" Identifier "calibration" MatchProduct "eGalax Inc. USB TouchController" Option "Calibration" "4094 -35 4026 10" Option "SwapAxes" "1" EndSection xinput_calibrator --device "eGalax Inc. USB TouchController"

For this, please enter the following command (in one line): Enter the following content here and amend the four values of the "calibration" option with those, which have been outputted to you in the previous step: Finally, you have to restart the Raspberry Pi for the last time: Now the Touch function is ready to use. Section "InputClass" Identifier "calibration" MatchProduct "eGalax Inc. USB TouchController" Option "Calibration" "4094 -35 4026 10" Driver "evdev" EndSection sudo nano /usr/share/X11/xorg.conf.d/99- calibration.conf sudo reboot

Connect the display with the provided power supply. Then, connect your computer with the display, using an HDMI– or VGA-cable, depending on your preference. You can further connect your computer with the Touch interface using the USB cable, if the operation via Touchscreen is desired. This requires an additional driver installation though. The drivers for the Touch function can be found on this website. In order to ensure the touch function of the display even when using several screens, the multiple moni- tor function must be activated in the eGalax Touch program. For this, please first open the program: ! Attention! On some systems, it may happen that the the lastest drivers are not fully func- tional. In this case, better results can be achieved with older drivers. You can download an older driver here.

After activation, you will be prompter to perform anoth- er calibration. If this does not take place automatically, please proceed as follows:
