Touchscreen Serial Interface
All touch controllers are configured by default to provide serial
communications at 9600 baud, 8 data bits, 1 stop bit, and no parity.
For Allen-Bradley monitors equipped with touchscreens, a serial (6 ft)
communications cable is included. You can also create your cable.
The cable is a straight-wired serial (RS-232) cable with a male DB-9
D-shell connector on the monitor end.
The cable provides a communications channel between the
touchscreen controller, which is mounted inside the monitor, and an
RS-232-C serial port on the host computer. Because the touch
controller obtains power from the monitor’s power supply, no
external touch power connections are necessary.
Software supplied with the touchscreen must be loaded on the host
computer to handle communications with the touch controller over
the channel.
Because the touchscreen emulates a mouse, there may be
compatibility issues involving how the touchscreen emulates mouse
buttons, especially multiple buttons. For a complete discussion of
these issues and how to troubleshoot them, refer to the touchscreen
documentation.
