Hello - I am trying to connect my Humminbird 947C to my West Marine VHS 580 radio so the radio can receive the boats current GPS coordinates, so far - no love - the radio makes no indication it is connected to anything.
On the Humminbird I have connected Power (of course), Speed/Temp, GPS Antenna, and 3D Transducer, the four plugs grouped together.. The 947C has NMEA Enabled in the Advanced menu, the GPS Wire to the antenna has a pig tail with a RED / WHITE / BLACK wires under a cap. The 947C is running software version 4.75.
The radio has two versions of its manual out there showing the NEMA+ wire as being either Yellow or Green and the NMEA GND as being the bare wire. I have connected both Green and Yellow and neither has worked.
I have made these connections;
Humminbird White (NMEA+) to WM580 Yellow - not functional
Hummingird White (NMEA+) to WM580 Green - not functional
Humminbird Black (NMEA GND) to WM580 Bare
Humminbird Red - not connected.
Per the discussion here ;
http://forums.sideimagingsoft.com/index.php?topic=4014.0I was thinking about trying the AS-HHGPS Cable in the second accessory port labeled #4 on page four of the 947C Manual. I was then going to connect AS-HHGPS White cable to the WM580 Yellow.
Is this the right thinking or should I be doing something else.
Thanks - Steve
