VOIP Interconnect Board

DSCN2325

The VOIP Interconnect board was designed for interfacing with Masters Communications RA40/RA42 USB Radio Interface board and our SA-818 Carrier board.

Connection is easy for other types of USB radio interfaces and other two-way radios with proper configuring.

Two versions of this board are available.

Vertical header pins on .1″ centers to connect to external devices and horizontal header pins for installations where vertical clearance of the interconnect cabling is an issue.

Components are on-board for providing the DC voltage needed by some electric condenser type microphone elements or microphones with DTMF encoder circuitry.

Below is an example showing a complete radio Allstar node built into an obsolete 800MHz MOSTAR chassis using our VOIP Interconnect Board, providing local control of the radio’s DTMF microphone, the radio’s On/Off switch, volume control potentiometer, front panel speaker and led indicators.

The best of both worlds…Local Control or use your HT and move around your house while still operating your Allstar node.
