Wiring my Humminbird to my Simnet

[High Bidder]

I once again am trying to connect my new Humminbird 858c to my simnet system for my autopilot. I can splice the cables but I need to know which wires to connect together. The Simnet cable has 4 wires, Red(power), Black(grd), Blue and yellow(data). The Humminbird has 3 wires on the GPS puck cable, Green( GPS NMEA out), Black(grd), White(control head NMEA out). I bought a Humminbird unit because my boat has a Airmar thru hull transducer with Humminbird wiring.

 

Thanks

Simnet is essentially NMEA-2000. The Humminbird description sounds like NMEA-0183. Does the 858c have NMEA-2000? I'm not sure what you are trying to do, but to interface NMEA-0183 with Simnet you need an AT-10 adapter.

It amazing that my old Lowrance Globalmap is a NMEA 2000 system but this new Humminbird is not. Thanks for the info.

I think your unit has Ethernet, and there are also Ethernet to NMEA-2000 adapters, like the Humminbird AS-ETH-NMEA2K.

Thanks for the info. The Ethernet adapter would work. Now I have to decide if I want to spend the $200 for the adapter and cable. I don't know how long my old Globalmap will last and I wanted to be prepared to change to the Humminbird. I hate to be on a two week fishing vacation and not be able to keep fishing because of equipment failure.
