Wireless: Interfacing Tempest base station 4-wires with RTS RVON I/O audio
The Tempest series of base stations (Tempest 900 and 2400) can route their 4-wire audio to the RVON DB-9 voice over IP interface unit using a custom RJ-45 cable to DB-9M connector. See cable diagram below for audio input and audio output pin outs.
Note: the Tempest basestation has both a 2 wire and 4wire connector so can be connected to a variety of 3rd party devices
