CHAPTER 4: CONNECTING TO DEVICES AND NETWORKS
RS-232 connections
The D400 accepts connections to RS-232 type devices through the RS-232 Adapter. The
RS-232 Adapter (GE Item No. 520-0207LF) is an RS-232 serial I/O adapter card that plugs
into any serial communication slot (slots 1 through 8) on the D400. It contains two
independently isolated RS-232 serial ports (
Port 1
and
Port 2
) each with a DB-9 connector.
The required RS-232 cable is a serial null modem, DB-9F to DB-9M cable. The cables must
be shielded and DB-9S connector covers must provide EMC shielding (e.g. metallized
plastic or die-cast metal covers).
See “RS-232 adapter” on page 36 for configuration options.
To connect RS-232
type devices to the
RS-232 adapter
Use the cable connection shown in Figure 31.

RS-485 connections
The D400 accepts connections to RS-485 2-wire and 4-wire type devices through the RS-
485 Adapter. The RS-485 Adapter (GE Item No. 520-0208LF) plugs into any serial
communication slot (slots 1 through 8) on the D400. It contains two independently isolated
