NMEA 0183 how to connect my new plotter
I just bought my boat (used) and want to replace the old Raymarine 520 plotter (greyscale) with a new NAVMAN Tracker 5600 (color). All other instruments on the boat are Raymarine (Wind, depth-speed, & Autopilot). I want to understand and learn how to make the connections so the plotter reads the inputs of the other instruments and also connects to the Autopilot. Is this just a matter of creating sound connections or do I need more? The Raymarine plotter seemed to had a bunch of wires coming in, at least I didn't see any additional box (multiplexer???) B.t.w. these connections were made in a horrible matter and secured with electrical tape ....) when I took the instrument of the Nav-Pod today. I expect the new plotter to arrive within a week or two and want to learn what needs to be done so I can install it the proper way. The NAVMAN manual gives me the colorcodes for the wires, but of course doesn't go into any specifics ....
Any help would be greatly appreciated.
