Pull a proper NMEA
2K stranded twisted pair/shielded cable. In you want extra pairs pull an additional cable.
I havn't boned up yet on NMEA 2000
since I don't have anything yet that needs it. Is it full-duplex, so that one pair both transmits and receives? All my stuff is NMEA 0183
, so it needs one pair to transmit, and a separate pair to receive. Then with one high speed and one low speed signal both in and out, that's 8 conductors right there. The chartplotter
needs the high speed, but I think the autopilot
is happy with low speed.
So I may run a NMEA 2000
cable for future use, then an 8 conductor for all the 0183 stuff, and I should have all I'll ever need.
