Common Control Equipment Installation
Unselect Voice +/- (Uns +/-)
This balanced pair of audio signals from the CIC provides the dispatch console with a
nominal 0 dBm output of the unselected channel's receive audio. It is important that these
two signals are physically paired (twisted) for most of the wiring run.
Microphone Voice +/- (Mic +/-)
This balanced pair of audio signals from the dispatch console provides the CIC with a
nominal 0 dBm output of the microphone's transmit audio. It is important that these two
signals are physically paired (twisted) for most of the wiring run.
IC Data +/- (IC +/-)
This differential pair of data signals from the CIC provides the dispatch console with
status of the system. The data rate is selectable between 1200 and 9600 baud. It is
important that these two signals are physically paired (twisted) for most of the wiring run.
CI Data +/- (CI +/-)
This differential pair of data signals from the dispatch console provides the CIC controls
of the system. The data rate is selectable between 1200 and 9600 baud. It is important that
these two signals are physically paired (twisted) for most of the wiring run.
Ground-Data (GND)
These two signals carry a ground reference for the data signals between the CIC and the
dispatch console. Ground signals are required when passing the data directly over metallic
connections.
Mon A Audio (MON A +/-)
This balanced pair of audio signals from the console interface card provides receive audio
to an external speaker. The source of this audio is programmable by the operator.
Mon B Audio (MON B +/-)
This balanced pair of audio signals from the console interface card provides receive audio
to an external speaker. The source of this audio is programmable by the operator.
