The problem, however, could be as simple as a missing/damaged terminator or loose/dirty connectors. This is because if there is a short or open in the trunk or drop lines it can affect the entire network, downgrading overall performance or even taking down the network. So how likely is it that this will happen? Let me quote from the ON article (emphasis mine).īecause cabling problems are especially troubling for bus or linear topology networks such as NMEA 2000, the cabling should be checked first if any malfunctions start to manifest. That’s going to be fun! As a famous ocean racing skipper was heard to say after nearly running aground on Cape Sable in the fog, “only your laundry knows for sure”. Murphy will make absolutely certain that all of this happens just as you are making an approach to a tricky harbour crawling with traffic…in the fog.

You see, the thing is that many devices use the NMEA backbone not only to communicate with other devices, but to communicate with their own sensors. You knew there was a “but” coming, right? Most every techy type in the marine journalism community has been waxing eloquent about how cool this is.

For those of you who are not aware, NMEA is a standard backbone cabling system that allows you to connect every piece of electronic gear on your boat together, regardless of what company manufactured each piece. I was just reading an article on the NMEA 2000 marine network standard over at the excellent Ocean Navigator blog.
