The SV-COM-425 is a remotely controlled VHF communications transceiver. All
functions are controlled using a binary protocol over a serial RS-232 data link. The user
will require a SV-COM-450 panel mounted control head to control this transceiver.
Installation:

structure of the user’s aircraft. The supplied harness connects the SV-COM-425 to the
SV-COM-450 control head. Power for both the units should be connected to the Red wire
in the harness, and the Black wire should go to the bus power’s return point.
