CHAPTER 3: SETTING UP COMMUNICATION CARDS
Types of communication cards
The types of communication cards included in your D400 depend on what was ordered for
your substation application. The following types of communication cards are available for
the D400:
• Serial (Slots 1 to 8)
– RS-232
– RS-485
• Fiber Optic Serial (glass or plastic)
– IRIG-B (Slots 9 and 10)
–IRIG-B Input
– IRIG-B Distribution
• Network (Slots 11 and 12)
– 4-Port Twisted-Pair Ethernet Switch
– Hot Standby Fiber Optic Ethernet Switch
– Redundant Twisted-Pair Ethernet + COM2 Port
–COM2 Port
• USB KVM (Slot 13)
– Keyboard, Video and Mouse
Changing card settings
The communication cards are factory installed with default settings. You may want to
adjust individual card settings to work with your specific system set up.
To change the
settings on a
communication card
1. At the rear panel of the D400, using a flathead or Phillips screwdriver loosen (but don't
completely remove) the two screws from the top and bottom of the communication
card.
2. Using the flathead screwdriver, gently pry the top of the card from the slot and remove
it from the chassis.
3. Refer to the instructions in the following sections to make any required changes to the
switch settings on the card.
Use a small flathead screwdriver (same as used to remove the communication card
screws) to change switch positions.
4. Slide the card into the same slot you removed it from, and tighten the two screws.
For proper transient protection, the recommended tool torque settings for communication
card screws are 2.6 in-lb [0.294 Nm].
RS-232 adapter
The RS-232 Adapter (GE Item No. 520-0207LF) is a standard 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 J3 and Port 2 J2) each with a DB-9
connector with common shields.
