9-2 Communicating with Devices on a Serial Link

Step 1: Configure the hardware

The RS-232 port is an isolated serial port built-in to the front of the controller.

Refer to Access Procedures on page C-1 to understand how to gain access to

the front of the DriveLogix controller.

To connect to the serial port:

1. Select the appropriate cable.

The 1756-CP3 cable attaches the controller directly to the controller.

If you make your own cable, it must be shielded and the shields must be tied to

the metal shell (that surrounds the pins) on both ends of the cable.

You can also use a 1747-CP3 cable (from the SLC product family). This cable

has a taller right-angle connector housing than the 1756-CP3 cable.
