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 to
the MS39
xx
RigCom Stations.
The MS39
xx
uses an unbalanced system for communication and uses the negative of the audio pair as the
ground reference for the control signal. The Model 400-001 has the ability to operate unbalanced or
balanced. In the balanced system, the audio pair is not ground referenced and the control signal requires a
ground signal.
For interoperability between the Model 400-001 and the MS39
xx
Series, configure the Model 400-001 for
an unbalanced system by placing jumper
P3
in the
UNBAL
position. No changes are required to the
MS39
xx
Series station(s). For Master/Slave operation, connect
AUDIO–
to
AUDIO
(WH)
,
AUDIO+
to
AUDIO
(BLK)
and
EXT
CONT+
to
KEY
. For common line only the audio wires require connection.
The following wiring diagrams are for the different configurations of a RigCom system:
