1.01  How do I connect my touch screen to my PC.
Carefully connect the Touch Screen 9 pin D-type connector ( shown circled below ) to COM1 or COM2 on your PC. Ensure that your touch screen is properly connected as listed in the instruction manual that came with your monitor. Also check that the monitor image is correctly centered and aligned before installing the TouchKit software.




1.02. How do I install the touch screen software.
Insert the TouchKit V3.1.5. CD into the your CDROM, the CDROM should automatically run ( depending on the settings for your CDROM drive), if it does not, navigate to D:\autorun.exe where "D" is the letter or equivalant for your CDROM drive. Double click autorun.exe to begin the installation.



Select your preferred operating system by click on the menu buttons. In the example below Windows 2000/XP has been selected....

The installation process will now begin. Click Next to continue....

When the Setup Type screen appears, do not check the PS2AUX box as this is not required for your serial touch screen. Click on Next to continue....

If you wish to install utilities to Rotate the screen or Shutdown your PC, then select the boxes below however the installation of these utilities is not covered by this tutorial so it is suggested that you do not install these items at present, they can always be installed at a later date. Click on Next to continue....



Choose the destination folder where the software will be installed. The default location is C:\Program Files\TouchKit otherwise select Browse to change the destination folder.



Choose the folder to which the program icons will be added. The default folder is TouchKit.
Click Next to continue the installation..



The screen below will appear momentarily as the TouchKit drivers are installed.



After installation the TouchKit software will automatically search for the touch controller inside your monitor. In the example below, a touch controller has been detected on COM1. If you connected your monitor serial cable to COM1 click Yes to register the touch controller with the TouchKit software. If the software does not find a touch controller, the most likely cause is that the serial cable is not connected to your PC.



The software will continue to search the remaining serial ports on your computer for touch controllers. If the software detects a touch controller on COM3 for example and there is no touch screen monitor connected to COM3 click No to ensure this controller is not added.



After all COM ports have been searched for Touch Controllers the Setup Complete screen below will be displayed. It is recommended that the Yes, I want to restart my computer now option is selected. Select Finish to complete the installation.
