Connecting with other digital matrix intercom systems
Because FS II 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 FS II 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.

Connecting with other 4-wire devices
Various other 4-wire audio devices can be connected with FS II. The Clear-Com
EF-701M 4-wire interface can be used to attach additional partyline channels to
FS II, converting them from partyline on the wired side to 4-wire on the FS II
side.

The Clear-Com IF4W4 interface can be used similarly. The audio input side of the
FS II 4-wire connectors could be used for additional program or other audio inputs
that could then be accessed by FS II beltpacks. The audio output side of the FS II
