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.
Cabling required to make physical connections to the D400 are as follows:
Media
Fiber Optic Ethernet
Twisted Pair Ethernet
Redundant Twisted Pair Ethernet 10/100BaseT
PPP Serial Over External Modem
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).
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.
