Touchscreen Serial Interface
All touch controllers are configured by default to provide serial
communication at 9600 baud, 8 data bits, 1 stop bit, and no parity.
For monitors equipped with touchscreens, a serial 2 m (6 ft)
communication 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 communication 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.
