Navman GPS to Horizon VHF Link
Had to replace our VHF and bought an Horizon GX1500E. Fitted OK, but now want to link the DSC facility to existing Navman Trackfish 6600 GPS. Can anyone help with wiring? Navman has what appears to be a DIN socket! Horizon, has Blue, Green, Grey and Brown wires [brown apparently not needed - so says manual].
Pin 1 - Black, Ground: power negative NMEA ground
Pin 2 - Brown, not used
Pin 3 - White, NMEA out
Pin 4 - Blue, NavBus - [negative]
Pin 5 - red, Positive power in [10 - 35V DC]
Pin 6 - Orange, NavBus + [positive]
Pin 7 - Yellow, Auto Power in
Pin 8 - Green, External beeper.
NavBus is apparently proprietary system to Navman!
Blue -NMEA Input + [Connect to NMEA (+) output of GPS
Green - NMEA Input - [Connect to NMEA (-) output of GPS
Gray - NMEA output + [Connect to NMEA (+) input of GPS
Which of these three goes to which pin on the DIN Plug?
How is the DIN plug pins numbered - orientation of plug obviously critical?
All assistance on this one appreciated.
