data is on the same N2K network, and the converter allows the Raymarine
to see the data coming from Zeus2. The converter makes it backwards compatable, IMHO. Not using NMEA0183 wires.
I looked up the ST70, and it says it is SeatalkNg. So it should hook directly into the N2K network using a spur cable. SeatalkNg and NMEA2000 (N2K) are the same thing. OMG, just ignore NMEA0183, sixth pin, or whatever. This is not difficult, but it has to be done exactly correct. Just need to get the right cable and pay attention to backbone and spur connections to instruments. If I were you, I would concentrate on getting all data onto the N2K network, and avoid any extra NMEA0183 hookups. Very clean installation
. All one language (i.e., N2K). All equipment
on the network (N2K) can see data from other instruments. Don't confuse your daisy-chained, Seatalk cable-connected instruments as sharing N2K network data, because they are not. But one end of that daisy chain needs to be hooked up to N2K network, so that Zeus MFD can see that data.
Am I missing something here?
