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. Ensure 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.
Note: If you are using older touchscreen software, you may be
prompted for the type of touchscreen controller being used.
