Appendix A—
Interfacing a Model 400-001 RigCom Station to a
MS39xx RigCom Station System
The Model 400-001 RigCom Station is designed to operate as a field replacement or system addition in
systems containing MS39
xx
RigCom stations.
The MS39
xx
stations use an unbalanced system for communication and the negative of the audio pair is
used for the ground reference of the control signal. The Model 400-001 can operate in an unbalanced or
balanced system. In a balanced system, the audio pair is not ground referenced and the control signal
requires a ground signal.
Configure the Model 400-001 for unbalanced operation by placing jumper
P3
in the
UNBAL
position for
interoperability between the Model 400-001 and the MS39
xx
Series stations. No changes are required to
the MS39
xx
Series station(s). For Master/Slave operation:
1.
Connect the
AUDIO
−
to
AUDIO
(WH)
terminal.
2.
Connect the
AUDIO+
to
AUDIO
(BLK)
terminal.
3.
Connect the
EXT
CONT+
to the
KEY
.
Only the audio wires require connection for common line operation.
The following wiring diagrams are for the different configurations of a RigCom system:
