Because CellCom 10 features standard 4-wire ports, with an input pair and an
output pair, virtually any 4-wire signal can be connected with it. Make sure to
properly match the input and output pairs between the digital matrix port and
the CellCom 10 4-wire port (see diagram below).
The pinouts for the first two 4-wire ports contain both audio and data
connections, though the data connections are not currently used. Those pinouts
are shown in the following table.
...
The remaining two 4-wire connections are audio only, and the data connections
are unterminated.
Within the configuration software of the other digital intercom system, configure
its connected port to 4-wire or similar. Adjust the input and output levels either
at matrix side or within the CellCom 10 front-panel display for the particular
CellCom 10 4-wire port.
CONNECTING WITH OTHER 4-WIRE DEVICES
Various other 4-wire audio devices can be connected with CellCom 10. The
Clear-Com EF-1M 4-wire interface can be used to attach additional party-line
channels to CellCom 10, converting them from party-line on the wired side to
4-wire on the CellCom 10 side.
The Clear-Com IF4-B interface can be used similarly. The audio input side of
the CellCom 10 4-wire connectors could be used for additional program or other
audio inputs that could then be accessed by CellCom 10 beltpacks. The audio
output side of the CellCom 10 4-wire connectors could be used to route a
CellCom 10 wireless beltpack user’s voice out of the system for paging or other
reasons, similar to the SA OUT connector.
When using the CellCom 10 4-wire ports in this way, make sure that proper
connections are made between CellCom 10 and the other device. Adjust the
input and/or output levels either at the 4-wire device or within the CellCom 10
front-panel display for that particular 4-wire port.
