I don't have hands-on experience with the NX2, but from a quick peruse of
the server manual, the only connection, and path between the NX2 and your PC for NMEA data, is the
serial cable.
So, you need something in your PC to 'serve' the NMEA data from the NX2 onto the LAN or
wifi. I had a quick peek at the seaPro site - they mention a
network option but I couldn't find out much about it. You should contact seapro for more information
There's likely some
commercial software to do that serving, but there's also
an open-source NMEA server... which is a bit harder than
plug and play, but not too hard. And
software does not like sharing
serial ports with other software, which means some form of
hardware or software serial splitter, if you want to stil use seapro AND serve that same NMEA data elsewhere. (It might be as simple as feeding the serial from the NX2 into two serial
ports, since you're just going to be reading NMEA data over it, i believe)
Another idea - split the NX2 serial out into the PC for seaPro, and into a small single-board computer like the Raspberry Pi running the aforementioned NMEA server, with a USB-wifi dongle... and then you wouldn't need the iNavConnect ...
Hope there's something useful here.
