Install the Controller Chapter 2
To connect a workstation to the serial port, use one of these cables:
• 1756-CP3 serial cable
• 1747-CP3 cable from the SLC
product family (If you use this cable,
the controller door may not close.)
If you make your own serial cable,
follow these guidelines.
• Limit the length to 15.2 m
(50 ft).
• Wire the connectors as shown.
• Attach the shield to both
connectors.
Follow these steps to use RSLinx software to configure the RS-232 DF1 device
driver for serial communication.
1. In RSLinx software, from the Communications menu, choose Configure
Drivers.
