I have purchased a boat with a Raymarine 4000+ autopilot and a Magellan FX324 plotter. I'm not sure how to connect the two uning NEMA outputs. The Magellan talks about "RS422 orange wire,and "RS422 yellow wire" outputs but the Raymarine talks about "Data out +ve"and "Data out -ve" Has anyone experience of pairing these two? If I wire them up irrespective of polarity am I likley to cause any damage ?

4000+ Manual
I have a 4000+ with a Navman 5500i interfaced. The 4000+ "data in -ve" should be connected to ship's ground and the "Data in +ve" should be connected to the NMEA output of the GPS. This is per the Raymarine support site at http://www.raymarine.com/raymarine/default.asp?site=1§ion=3. You can download the 4000+ manual at the above site, and you should reference your plotter's manual for further guidance. My Navman works in the above configuration. Please consult the Raymarine help site and your GPS manual for your installation, and don't make any connection you aren't sure of just to "try it out". You also need to consult the 4000+ manual to see what NMEA "sentences" it will read, and confirm that your GPS outputs those "sentences" You should also confirm the version of NMEA the GPS puts out. I believe the 4000+ will read v2.5 or greater (this can be confirmed on the Raymarine help site as well, I think). Good luck!

NMEA to ST4000+
The ST4000+ Wheel Pilot only has NMEA input, but your GPS/plotter probably has both input, and out put. If you are sure which are + and - output wires, connect them to the NMEA terminals on the auto pilot. Remember that you have to be actively navigating to a point before the auto pilot will see any information from the GPS. The auto pilot understands NMEA0183, so check that the GPS is talking in NMEA0183. There is a new version called NMEA2000 which most new equipment can use (AIS receivers are the most common user of this new standard as it is much faster). You can read about NMEA at this link.
