Make an RS-232 Connection to the Controller

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

To connect to the serial port:

1. Determine whether you need an optical isolator.

If you connect the controller to a device outside of the system’s enclosure,

consider installing an isolator between the controller and device.

One possible isolator is the 1761-NET-AIC interface converter.
