Pin
Description
1
TX_MUTE (External MUTE Command)
If pin 1 (MUTE COMMAND) is connected to pin 5 (MUTE COMMON) the SSPB
is enabled (RF ON).
If pin 1 (MUTE COMMAND) is not connected to pin 5 (MUTE_COMMON) the
unit is disabled (MUTE).
2
TX_AL_NC (FAULT-NC) Normal closed contact of TX_ALARM (FAULT)
Relay. If closed to pin 2 (TX_AL_COM) indicates the FAULT state of the unit.
3
TX_AL_COM (FAULT-COM) FAULT relay common
4
TX_AL_ NO (FAULT-NO) Normal open contact of TX_ALARM (FAULT) Relay.
If open relative to pin 2 (TX_AL_COM) indicates the FAULT state of the unit.
5
MUTE_COMMON (common)
6-9
N/C (not connected)
4.2 RS-232 INTERFACE
This serial communication interface offers to the operator the essential monitoring and control of
the SSPB using any PC terminal software. An IBM compatible personal computer can be
connected to this port. This interface is located on the back panel of the SSPB (see
Figure 5
at
page 24). The mounting connector is a female, 9-pin DB-type with a pin assignment as shown in
TABLE 4
.
