APPENDIX C: JUMPER SETTINGS
The base station has internal jumpers that are used to set ISO broadcast restrict, power detect by-pass, and 2-wire
channel termination.
ISO Broadcast Restrict
This feature prevents ISO communication from being broadcast from one COMMUNICATOR
®
to other Communicators.
Local headset ISO will still be broadcast, and the local headset will still receive ISO communication. To enable this feature,
set JP4 to ON.
WARNING! If no termination is present on the line, enabling this feature will cause feedback in the headsets.
2-Wire Channel Termination
If termination of the base station is necessary (such as when multiple base stations are daisy chained), set the JP5 (A)
and/or JP6 (B) jumpers to the ON position on one base station, when connecting multiple base station together via 2-wire
connection. Only one base station should be terminated per channel.
