MultiDyne Video & Fiber Optic Systems has introduced the COMMS-2000 two-wire-to-four-wire intercom interface.
The COMMS-2000 interface allows the conversion of a single channel of standard or TW party-line intercom to four-wire audio, while also converting call signals to RS-422 data. It also can convert the signal to its original form.
The resulting audio and RS-422 data from the COMMS-2000 can then be sent to a Clear-Com Matrix port, fiber optic converter, such as the MultiDyne Fiber-Comms or connected to another COMMS-2000 over twisted-pair cable such as CAT-5E.
With hybrid null, offering superior isolation between sender and caller audio, and wide-range level controls, the COMMS-2000 may also be used as a stand-alone two-to-four-wire converter. It is also an integrated component for the LiGHTBoX field portable fiber optic transport system.
