The Furuno FCV range of salt water Fish Finders all have an NMEA0183 output that can drive our Sonar Server.
The FCV585, FCV587, FCV620 and FCV627 all share the same wiring details for the Power/Data cable and the wiring diagram can be seen by clicking here.
It is important that you check that the Depth and GPS sentences are turned ON in the Installation>NMEA menu.
