About the DH485/RS-232C Module
The DH485/RS-232C interface module, catalog number 1747-KE, is a
communication interface module that acts as a bridge between DH485 networks
and devices requiring DF1 protocol. The DF1 port on the interface module can be
configured for RS-232/423, RS-422, or RS-485 devices.
Residing in an SLC 500 chassis, the module is ideally used as an interface module,
linking remote DH485 networks via a modem to a central host.

Before You Begin
Before you begin to install the module, you need to:
• identify the communication ports,
• locate the LED indicators, and
• set the module jumpers.
Identify the Communication Ports
There are three communication ports on the front of the DH485/RS-232C interface
module. They are:
• CONFIG
• DF1
• DH485
The CONFIG port is used to configure the module with an ASCII terminal. This port
is a serial port that accommodates RS-232/423, RS-422, and RS-485 communication
modes. The CONFIG port is capable of operating full-duplex at 300, 600, 1200,
2400, 4800, 9600, and 19200 Kbps. It is electrically isolated to 500V dc.
