Lowrance Elite 7 HDI installation help!
So, got a new Elite 7 HDI today. It is my first higher end fishfinder, so as I was looking at the installation directions, I notice the power cord is a double cord. One side is marked power and is the standard red/black/yellow. Other side is marked NMEA0183, and has 5 wires (yellow/orange/blue/green/ground). This wire is something I was not expecting, and I am not sure what I am supposed to do with it. I think it is for networking, but I do not plan to network this unit at this time. (maybe in hte future) Can I simply wrap this wire and tape the ends? Does this need to be attatched to something? Do I need a professional?
