Assembly
1. The complete picture after assembly

2. Get the product in hand, assembly steps are as follows：First, face up flat the main screen, and
connect the screen data cable to the small adapter board, be sure to insert the black clip card of
two ends of the slot into inside. IF the card is not tight enough, it may cause abnormal display. In
the tutorials, all have clips apply the same settings.

3. Connect the other end of the adapter plate to a small boost driver board.

4.Connect the “screen menu control button board” to the “boost driver board”. Please do not
anti-plug.
5.Connect the power supply line of the screen to the “boost driver board”. Please do not
anti-plug.

5.Connecting the touch USB cable, Please do not plug it in the opposite direction. The easy way
to check is to straighten the touch screen control cable flat and “the flexible flat cable” with ‘silk
printing’ should face up.
The order of 4-pin plug wire is black, green, white, and red, as below shown.

Then, connect the other end of the 4-pin USB cable with the control board. Please do not
anti-plug.

Connect the other end of the USB control board to the a standard USB interface

Connect 12V DC power supply and HDMI VGA plug to the boost driver board. Reminder: before
power supply to the boost driver board, take away all conductors, under the boost drive board,
which may cause a short circuit, such as electronic components, metal plates, and other
electronic boards. In this case, the 2 welding foot under the boost driver board power supply
terminal have nothing to be protected, and positive and negative legs are very close, so it is easy
to incur power pin short circuit of power pin, as well as will burn the entire display device.

At this point, the connection assembly of the whole equipment has completed.
Tutorials
1. Plug the HDMI of the signal source pc (windows ubuntu) raspberry pcduino (here HDMI cable
needs connected before powered) or VGA cable into the corresponding boost driver board
interface tightly.
2. Plug the USB touch drive line into the source device
3. power supply the boost driver board with DC 12V
4. device source to power On
How to use screen control panel buttons
1. Power ON / OFF, press boot, press again shutdown, cycling
2.MENU / confirmation, control the language, brightness, contrast and other parameters set
of the screen, set and press confirmation again then return to previous menu
3. - PAGE DOWN
4. + PAGE UP
5. Select the video source

Windows System
Connect PC / laptop's video output cable to the boost driver board, and connect the USB cable of
touch screen driver to the PC / laptop, and then install XP-win7-win8 driver.rar.
You can calibrate the screen after the installation is completed.
LINUX
Similarly, connecting with linux kernel system, connect the video output devices to the boost
driver board, and connect the USB cable of touch screen drive to the device. Then follow the
tutorials of linux.rar to install the driver.
How to 32/64Touchkit drive：

1. Press ctrl + shift + t, open a terminal window, enter sudo uname --m ，
press enter
2. 2
If shows i686, means it installed the 32-bit operating system
If shows i686, means it installed the 64-bit operating system
After install the driver, calibrate the touch screen, then it can be used normally.
Mobile linux（take Raspberry for example）
The touch-screen calibration of mobile LINUX system is more complicated, so we here provide a
well configured xinput_calibrator (touch screen calibration procedure) raspbeery pi system
firmware. Customers just need to burn the firmware, and then below steps.
operating steps：

1. Please compile the system image ( Recommend to use 8G card
to Import mirror, the 4G card may be not enough ) on latest
debain-02-09 version.
Network location :
https://s3-ap-northeast-1.amazonaws.com/sain-amzn/20/20-011-208/raspbian0209_4G_touchsc
reen.zip
2. refresh system and Start the raspberries pie，using “ lsusb”
command to check if the touch screen is recognized or not :
pi@raspberrypi ~ $ lsusb
Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
Bus 001 Device 004: ID 1c4f:0002 SiGma Micro Keyboard TRACER Gamma Ivory
Bus 001 Device 005: ID 0eef:0001 D-WAV Scientific Co., Ltd eGalax TouchScreen
If you see A eGalax, it means that you had found the touch screen，if you do not find the
touch screen, would you please check if the USB interface contacted well，confirm the
touch screen chip is eGalax.
3. Login raspberries pie, enter into the graphical interface，Run
xinput_calibrator Program software, Calibration the screen（mirror
had installed the software）
pi@raspberrypi ~ $ xinput_calibrator

The screen will have a notice and mention you to click the Small fork diagonally，After you clicking, the
screen will prompt a adjustment of information，as following：
Calibrating EVDEV driver for “eGalax Inc. USB TouchController” id=8
current calibration values (from XInput): min_x=1938, max_x=114 and min_y=1745,
max_y=341
Doing dynamic recalibration:
Setting new calibration data: 121, 1917, 317, 1741
–> Making the calibration permanent <–
copy the snippet below into ‘/etc/X11/xorg.conf.d/99-calibration.conf’
Section “InputClass”
Identifier “calibration”
MatchProduct “eGalax Inc. USB TouchController”
Option “Calibration” “121 1917 317 1741″
Option “SwapAxes” “1″
EndSection
4.Coping the following content according to the notice
Section “InputClass”
Identifier “calibration”
MatchProduct “eGalax Inc. USB TouchController”
Option “Calibration” “121 1917 317 1741″
Option “SwapAxes” “1″
EndSection
5. open File ”/usr/share/X11/xorg.conf.d/01-input.conf“，
delete the data in the file already exists，then put the content you
copped to the file，then saving.

pi@raspberrypi ~ $sudo nano /usr/share/X11/xorg.conf.d/01-input.conf
6. Restart the raspberries pie, then you can enjoy your touch
screen well.
