NMEA2000 Testing & Troubleshooting

My brother in-law bought a sailboat and was having some issues with the mast mounted wind sensor. Not only was it hard to access (it’s over 60 feet high) but the boat uses the NMEA2000 data bus to connect all the instruments. A further complication is that it uses the SIMRAD SIMNET network cabling. I did some research and found a way to make a very cost effective DIY adapter to allow you see the NMEA2000 traffic in real-time using very good free software.
