DH485/RS-232C Interface Module 5

Publication 1747-IN006B-EN-P - October 2005

The DF1 port is used to interface the module with user devices or a modem using
DF1 protocol. This port is a serial port that accommodates RS-232/423, RS-422, and
RS-485 communication modes. The DF1 port is capable of operating full-duplex at
300, 600, 1200, 2400, 4800, 9600, and 19200 Kbps. It is electrically isolated to 500V
dc.

The DH485 port is used to interface the module with the DH485 network. This port
is not isolated and cannot directly drive a multi-node DH485 network. You must
use a 1747-AIC link coupler to link port DH485 with the DH485 network that
includes multiple SLC 500 controllers.

Refer to Figure 2 for the location of the communication ports.

Locate the LED Indicators

There are eight LED indicators on the front of the module. These LED indicators are
used for module diagnostics and status indication.

Refer to Figure 2 for the location of the LED indicators.
