Enabling the Touchscreen Interface
The RAC6185 Industrial Flat Panel Monitor (6185-F) provides a female DE-9
connector on the bottom panel. This connector provides the serial interface
for the touch controller.
Interconnecting wiring to the host serial port connection is shown in the
following table.
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.
