[CA] [CA11] VHF TO GPS HOW DO I CONNECT

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum jaberwoky,

Q1. The VHF is a standard horizon 1600e which I believe works on the NMEA 0183 which has 4 split wires to connect to gps blue green gray and brown
A1. As you have suggested, the SH 1600e supports NMEA 0183 communications. The SH 1600e does not support NMEA 2000 communications.

Q2. Can i strip the end off my ST ng cable to reveal 4 wires? or buy a plug with 4 split wires to connect together?
A2. Negative. The a6x/a7x MFDs support NMEA 2000 communications. These MFDs do not support NMEA 0183 communications. Please click here to view a FAQ addressing how GPS data from your a-Series MFD may be supplied to your VHF radio. Per the SH 1600 installation guide, its NMEA 0183 IN+ lead is features a blue insulator and its NMEA 0183 IN- lead features a green insulator.

A3. Can I buy a separate gps Arial and connect direct?
A3. While this may be possible, it would require a GPS sensor supporting NMEA 0183 communications, which Raymarine no longer manufactures.
