Figure 29: D400 Field and Network Connections
The types of communication cards included in your D400 depend on what was ordered for
your substation application.
For a list and detailed description of the types of communication cards available, see
Chapter 3,
Setting Up Communication Cards
.
General cabling requirements
Cabling required to make physical connections to the D400 are as follows:
High-voltage installations
To provide higher EMC immunity and maintain CE Mark compliance, the serial cables used
for permanent RS-232 and RS-485 connections must comply with the following
requirements:
•
Cables must be shielded
•
D-type connector covers must provide EMC shielding (e.g. metallized plastic or die cast
metal covers).
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.
