Not all Humminbird products have an NMEA0183 Output suitable for connecting our Sonar Server to, but the 700, 800, 900 and 1100 series all have an NMEA0183 output that transmits Depth and GPS data. Also some of the other Fish Finders with an internal GPS also have an NMEA0183 Output such as the 161, 363 and 383c Combo units.
You will need the optional AS-HHGPS Cable Kit (P/No. 700030-1) that connects to the rear of the unit.

Make sure that the NMEA Output is set to ON in the Advanced Setup menu of the Humminbird unit.
