Great for diagnosing NMEA networks
I paired this with a Yacht Devices NMEA 2000 WiFi gateway (YDWG-02) and can now see all the traffic on the NMEA 2000 (or SeaTalk NG) network. Either a dump of all the traffic or seeing the data organized by source and signal. For example, I can see that my chart plotter is not talking on the network (problem with chart plotter) and that my wind direction and wind speed are reasonable even though the wind display is out to lunch (need to fix the display, not the sensor). I can even record the data in the raw format and email it to myself for analysis later on.
