Any recomendations? When I bought my GPS/Map It didn't occur to me to be NMEA compatible. I guess I could always just use an other fixed mount as well. My DSC VHF and future radar would be better suited connected.

The Lowrance Ifinders are waterproof and double as a good back up chart GPS. For less than $200 bucks, its good insurance.

I think some of the $99 blister pack handhelds might not be, but I think over the last few years even most of those got nmea out capability. Don't expect them to have NMEA inputs that support the return DSC sentence from your radio, but damn near every handheld out there is going have a nmea out to either an autopilot, vhf, or radar.

OK...I checked my owners manual on my throw-around Garmin etrex Legend. It says it is NMEA 0183. So is there a special cable I need to use to make connections? Are the cables universal for all brands? Can I only connect 1 other unit or is there some type of splitter?

I looked for the same thing for a lowrance H20, go to garmins website and look for what you need - you may be able to find a part #. You could also contact BOE here on THT.

Normally each bit of equipment will require its own specific cable/connector. In most garmins the NMEA in/out is generally included in the power cable. The cables are not universal but the NMEA connections are basically standard.

For a simple one way connection

NMEA OUT wire from the talker (say GPS in this case) to the NMEA IN wire of the listener (FF, Radio etc)
Ground to ground or specific NMEA common wire.

For 2 way comms then the NMEA IN wire connects to the NMEA OUT wire of the other device (say to receive depth on a GPS from a FF etc)

In general NMEA0183 will normally be able to connect 3 listeners to the one talker before things can start getting complicated and requiring other devices etc.

Regards, Kerry.

Forgive my ignorance...so do I need another power cable and then just splice the end of that to the new equipment's cable? How do I configure one cable to split to more than one piece of equipment?
