NAME
FUNCTION

N.C.
No Connection. Not internally connected.
1
INB
Transmitter 1 Logic Control. Drive INB high to connect NC3 and NC4. INB logic is ignored
when SWITCH asserts low.
2
COM3
Common Terminal 3. Transmitter 1 positive differential terminal. Connect COM3 to the transmit
interface transformer.
3
COM4
Common Terminal 4. Transmitter 1 negative differential terminal. Connect COM4 to the
transmit interface transformer.
4
GND
Ground
5INC
Transmitter 2 Logic Control. Drive INC high to connect NC5 and NC6. INC logic is ignored
when SWITCH asserts low.
6
COM5
Common Terminal 5. Transmitter 2 positive differential terminal. Connect COM5 to the transmit
interface transformer.
7
COM6
Common Terminal 6. Transmitter 2 negative differential terminal. Connect COM6 to the
transmit interface transformer.
8
SWITCH
Protection Switch Control. Assert SWITCH low to connect all switches to protection bus. When
SWITCH asserts low, SWITCH overrides all IN_ inputs. Assert SWITCH high to enable all
switches and let the respective IN control the switches.
9, 32
V+
Positive Supply Voltage. Bypass V+ to ground with a 0.1F ceramic capacitor.
10
IND
Receiver 2 Logic Control. Drive IND high to connect NC7 and NC8. IND logic is ignored when
SWITCH asserts low.
11
COM7
Common Terminal 7. Receiver 2 positive differential terminal. Connect COM7 to the receive
interface transformer.
12
COM8
Common Terminal 8. Receiver 2 negative differential terminal. Connect COM8 to the receive
interface transformer.
13
NO8
Normally Open Terminal 8. Receiver 2 differential protection terminal. Connect NO8 to the
protection bus.
14
NC8
Normally Closed Terminal 8. Receiver 2 differential terminal. Connect NC8 to LIU receiver.
15
NO7
Normally Open Terminal 7. Receiver 2 differential protection terminal. Connect NO7 to the
protection bus.
16
NC7
Normally Closed Terminal 7. Receiver 2 differential terminal. Connect NC7 to LIU receiver.
17
NO6
Normally Open Terminal 6. Transmitter 2 differential protection terminal. Connect NO6 to the
protection bus.
18
NC6
Normally Closed Terminal 6. Transmitter 2 differential terminal. Connect NC6 to LIU receiver.
19
NO5
Normally Open Terminal 5. Transmitter 2 differential protection terminal. Connect NO5 to the
protection bus.
20
NC5
Normally Closed Terminal 5. Transmitter 2 differential terminal. Connect NC5 to LIU receiver.
21
NO4
Normally Open Terminal 4. Transmitter 1 differential protection terminal. Connect NO4 to the
protection bus.
