CommLink Physical Configurations
ADVANCED DSP AUTO-NULLING
Once the two-party system is connected, a toggle of the AUTO NULL switch provides a digital
system null of the two-wire system, no matter what the load, without the need for manual
adjustments.
BELT PACK POWER
Each CommLink™ module can be powered from the Party line intercom circuit without an
external power supply, like a belt pack. Alternately, with a 12VDC power source, the
CommLink unit can act as a Party line power supply, providing enough 30VDC current to
support approximately ten belt packs.
FOUR-WIRE MATRIX MODE
The system links a MatrixPlus/Eclipse (Clear-Com®) or Adam (RTS®) family matrix frame and
two of the system's key panels over a fiber strand. All of the key panel functionality is
supported, including displays, controls, and communications to the matrix frame.
HYBRID MODE
The CommLink system can be used to connect a matrix frame in a control room or truck with
two party line channels in the venue, without the need for a separate hybrid adaptor.
A single CommLink unit can also act as a standalone digital system interface/system-to-
system adapter, utilizing the digital auto-nulling system. Connect two-wire intercom
systems to legacy fiber systems, two-way radios, satellite links, TV cameras, and other
communications devices with 4-wire circuits.
