Variety of mostly NMEA 0183 splitters and multiplexers. Maze of lines quickly put me off that idea.īrowsing through the 2010 Gemeco catalog, I stumbled on a product (and Theyĭid helpfully send me a Yanmar engine wiring diagram in case I wanted to tryĪnd make up the required harness on my own, but one look at the diagram’s This analog adapter is designed for Yanmar engines, and Maretron doesn’tĬurrently certify its use with motors from any other manufacturer. Solutions for getting NMEA 2000 data out of my analog engines: It took some research, but I came up with three Location near the top of the stairs to the staterooms.) Is especially true of the generator, as its gauge package is in a Lights generator, neither of which supports digital gauges? If I’mĬomplete monitoring system to the boat, it seems wrong to exclude them. Performance data? Or in my case, what about my Lugger wing engine and Lack electronic fuel injection and the engine computer needed to output What about the thousands of sail- and powerboat owners with older That’s all fine for folks with brand new boats, you J2K100 passes J1939 data from the engine network to the NMEA 2000 bus, RPMs on a twin-engine vessel, for example) or to drive physical gauges -Īnalog-looking engine gauges actually receive digital signals viaĮngine messages aren’t the same as NMEA 2000 engine messages, butĬonverter box to bridge the two networks together.

J1939 can be used to exchange data between two engines (to Happens to be the same wiring and communications standard on which NMEAīased).

Protocol called J1939 that runs over the familiar industrial CanBUS In general the same can be said for modernĮlectronically-controlled diesel prime movers most support an engine Harness or digital gauge to make the backbone connection. Have it easy: Mercury, Suzuki, Yamaha, Evinrude, and Honda all outputĮngine parameters in NMEA 2000 format, though you may need a funky Or hard, depending on the kind of motor you have. Gettingĭata onto the NMEA 2000 bus (and from there onto one of those displays) Other two are a wing (get-home) engine and a 12 kW generator. Has a single primary engine, we actually have three diesel motors on
