(DG) Smart controller x5 nmea

[Dkdoyle]

Nmea mux supports: gps, vhf with ais and gps, depth, c80.
Smartcontroller supports: c80, tiller motor, fluxgate, st70.

With the above everything worked except go to waypoint.

Now my C80 has died so I am looking at moving to NMEA2000 unit like a B&G Zeus.
I think in order to do that I need to bring up an 2k backbone and plug in (with Ray cable) the other port of the ST70 to the backbone. Get a 2k to 183 converter to plug in the nmea mux to the backbone. Finally plug in the new chartplotter.

Does that sound right?
