If it works the way the manufacturer's website indicates, the touch screen is an overlay on the LCD or CRT video screen. The pointer function is plugged into a PS2 mouse port.

Unplug the touchscreen from the mouse port and plug in a mouse. The video should not be affected, as it is transmitted through the monitor port. The manufacturer says you have to turn off the mouse acceleration setting to use the touchscreen, so you will probably need to turn that back on.

You might want to upgrade / convert to a capacitive or resistive type screen that will interface to any afore mentioned ports. It will have it's own software and screen / display can be configured easily by the operator.

AND, It may be significantly cheaper replacement than an IR model.

Example can be seen here:

No, I don't sell them - we use them in our machines that we manufacture.
