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.
