All models are supplied in a MiniMussel Shell enclosure suitable for use in harsh
environments.

The system provides flexibility in the types of intercom systems that can be used, in that the
system can link one type of party line system to another type of party line system, a matrix
frame to two key panels, or act as a two-wire to four-wire hybrid adaptor via fiber or as a
stand-alone local unit. Each of these operating modes is explained in detail later in this
document.
TWO-WIRE PARTYLINE MODE
Plug two channels of Clear-Com® PL (two XLRs) or RTS® TW (one XLR) into each CommLink
module and connect them with a fiber cable. The system will "translate" between two
systems so that you can have Clear-Com® at one end and RTS® at the other. It also translates
the call lights.
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.
