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
communications cable is required. A suitable cable can be obtained from
Rockwell Automation or you can create one. The cable is a straight-wired serial
(RS-232) cable with a male DE-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.
Setting Up the Touchscreen
Interface This section describes how to set up the touchscreen system. Setup involves
the following:
• Enabling the touchscreen interface
• Installing the software on the host computer that will handle
communications with the touchscreen controller
• Performing a calibration
