[GPSNavX]

We have since updated iNavX description once we learned Coastal Explorer stand alone could not be a NMEA data server, but only a receiver.

Both Coastal Explorer and iNavX can be setup to listen/receive NMEA data over TCP/IP. It is GPSGate on Windows (or MacENC on Mac) that must be configured to connect to a physical serial port(s) and then repeat that data to a TCP/IP port. So something like this:

GPS (or other NMEA data) -> Com port -> GPSGate -> TCP/IP Port

wireless connection ->

TCP/IP Port -> iNavX
TCP/IP Port -> Coastal Explorer

Typically one created an AdHoc network to achieve this.
