All touch controllers are configured by default to provide serial
communications at 9600 baud, 8 data bits, 1 stop bit, 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 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.
This section describes how to set up the touchscreen system using the
6157- C Industrial Monitor. 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
