SV-COM-425 User Manual 1 Dynon Radios LLC 19825 141st Pl NE Woodinville, WA 98072 Ph:(425) 402-0433 Fax: (425) 984-1751 SV-COM-425 User Manual 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: The SV-COM-425 transceiver is intended to be bolted or riveted onto the 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. Serial Protocol: 8 bit binary 1 stop bit odd parity 38,400 Baud Electrical Interface: 15 pin male DSUB-15 connector Pin Description Pin Description 1 Microphone, audio input 9 Ground 2 Ground 10 Audio out 3 Enable, ground to activate power 11 Ground 4 Ground 12 Ground 5 Push To Talk, ground to transmit 13 Ground 6 RS-232 TX out of Unit 14 RS-232 RX in to Unit 7 Supply Voltage 15 Ground 8 Supply Voltage
