Appendix B Touchscreen Serial Interface
Enabling the Touchscreen Interface
The monitors provide a female DB-9 connector on the side of the
panel. This connector provides the serial interface for the touch
controller.
The table shows how to connect the wiring to the host serial port.
Installing the Touchscreen Driver Software
To install the touchscreen driver software correctly, obtain the
following information about the host hardware:
•
The COM port in use for the touchscreen
Verify that the RS-232 cable is properly installed between the
monitor port and the host’s COM port.
•
The baud rate at which the controller is operating
You will need to match the baud rate at the COM port. The
controller baud rate is factory set at 9600.
Once you have obtained this information, install the software using
the installation disks found in the touchscreen accessory package.
Calibrating a Touchscreen
After installing the driver software, follow the calibration instructions
in the touchscreen documentation accessory package.
Following installation of the touchscreen software and calibration, the
touchscreen is ready to use.
