•Part 10. Integration Procedure
1. Connect controller with 5-wire resistive touch screen
2. Connect the controller to the motherboard via either USB port or
RS232 port
3. Connect the controller to 5VDC power (USB port can provide 5 VDC
Key board port or mouse port can provide 5VDC power for RS232
controller)
4. Install the appropriate touch system driver in correspondence with
operation system, (windows XP, 2K etc.)
•Part 11. Install Touch system Driver
1. Available Touch system Driver
Drivers can be downloaded from V Touch Driver CD or website:
Windows 2000 (for both home version & professional version)
Windows XP (for both home version & professional version)
Windows 2003 Server
Windows Vista
Windows 2008 Server
Windows CE 5.0 & 6.0
Linux
2. Driver installation and Touch System calibration guide:
A. Preparation: connecting 5- wire resistive touch screen, controller and application
device or computer with correct cable on the integration procedure.
B. Insert the V Touch Driver CD in to application system;
C. Find the instruction to complete the driver installation for Windows 2000/XP as
following:
Double click at the setup.exe file to start software driver installation. Then, the setup

program will guide user to complete software installation.
Press Next button to continue installation, then, a new dialog popped up as below,
his dialog shows to ask user if the PS2 filter driver for touch screen to be installed.
User can check this check for PS2 filter driver installation. The standard PS2 mice
can still work well after this filter driver installed because Touchkit PS2 filter driver can
work with both standard PS2 mice and PS2 touchscreen. But, this filter driver may
does not work with other devices with the PS2 mouse port. After check or uncheck
this check box, press Next button to continue installation. Then, it shows new dialog

as below,
Also, Touchkit software provides user with 4 points calibration. If the system needs 4
points calibration to make sure the touch accuracy every system reboot, user can
check every system boot up. If the system need 4 points calibration later, user can
check none. Press Next button to continue installation. The setup program prompts a
message box to hint
User to make sure that the Touchkit USB controller devices were well connected with
system USB ports to guarantee the USB touchkit device drivers updated after driver
installation. Then, just press OK to continue

•Part 12. How to Test the 5-Wires Resistive Touchscreen
Calibration, draw test tools and the linearity curve of the touch screen were listed shown
as below for user to do touch screen calibration and touch position test.
User can do calibration or draw test by pressing the function push buttons.

VTouch 5-Wires Resistive Touchscreen User Manual

1. Linearization Curve
Linearization curve of the touch screen is list in this page for reference and trouble
shooting purpose.
2. 4 points calibration
It needs calibration before the touch screen can work accurately. Whenever the user
feel the accuracy lost, user can do calibration again to get a more accuracy touch
function.
Pressing this button, a new window will be popped-up at the location when the touch
screen was mapped to area for this touch system to guide the user do 4 points
calibration.
User should follows the guide to touch and hold the blinking X symbol in the calibration
window until it does not blink to make sure that the utility can gather enough data for
computation. In addition, a time line bar is shown in the bottom of the window to
indicate time elapsed. If the touch screen was not touched before the time line bar
going to right end, the calibration task will be terminated
automatically.
3. Clear and Calibration
Press this button to erase the 25 points calibration/linearization parameters and force
user to do 4 points calibration again.After 25 points calibration data was clear, the 4
points calibration data will be invalid. It needs to do 4 points calibration.
4. Linearization
Linearization ( 25 or 9 points calibration ) function is used to compensate the touch
screen linearity. After linearization completed, the linearity of the touch screen will be
shown in the Linearity curve window.
Pressing this button, a new window will be popped-up at the location when the touch

screen was mapped to area for this touch system to guide the user do 25 points
calibration. User should follows the guide to touch and hold the blinking X symbol in the
calibration window until it does not blink to make sure that the utility can gather enough
data for computation. In addition, a time line bar is shown in the bottom of the window
to indicate time elapsed. If the touch screen was not touched before the time line bar
going to right end, the calibration task will be terminated
automatically.
5. Draw Test
This function is used for accuracy and performance check. Press this button and a new
pop up window will be popped up in the location where the touch screen was mapped
to the touch system as below,
