Touch Screen

The Panel C includes a resistive overlay touch screen on the flat panel display.

The touch screen has a resolution of 1024 x 1024 touch points (independent of screen
size) and provides an efficient and reliable method of entering information. The screen
responds to the touch of your finger with or without a glove.

The touch screen is connected internally to the COM3 serial port. If you install a card that
has settings that conflict with those of the COM3 serial port, you will need to change the
card’s configuration.

Touch Screen Driver for Windows

The integral touch screen of the Panel C is internally connected to COM3. Parameters
must be set within the driver so that they match the hardware settings. The factory default
settings are:

COM Port = 3
Address = 3F8 Hex
Interrupt = Com3 IRQ 9

These parameters are written into the system registry file by the driver setup utility. The
driver is installed, configured and calibrated at the time of manufacture.
