Utility Connections

3.4.1 Alarms Connector, P1
At present, Asynchronous Engineering Channel operation is not implemented in the
CDM-710/710L; this connection is therefore non-operational.
The P1 Alarms connector is a 15-Pin Type 'D' male (DB-9M) interface with
threaded jack nuts. The pinout depends upon whether the unit is in the Normal or
Redundancy mode for use with the CRS-170A (L-Band) 1:1, CRS-180 (70/140
MHz) 1:1, or CRS-300 1:N redundancy switches. The unit is put into 1:1 mode
under the Config: AUX
The connector pinout is as follows:
Pin #
8 Rx Traffic (De-energized, Faulted)
15 Rx Traffic (Energized, No Fault)
7 Rx Traffic
14 Tx Traffic (De-energized, Faulted)
6 Tx Traffic (Energized, No Fault)
13 Tx Traffic
5 Unit Fault (De-energized, Faulted)
12 Unit Fault (Energized, No Fault)
4 Unit Fault
11 Rx I Channel (Constellation Monitor)
3 Rx Q Channel (Constellation Monitor)
10 No Connection
2 AGC Voltage (Rx signal level, 0-10 volts)
9 Ext Carrier Off (TTL Lo = Mute, Open = Tx)
1 Ground
