The J1939 Yamaha adapter kit shown above is a direct connect to the Garmin j1939 port and so is isolated from the House power and/or N2k power bus. There is a "NMEA2K Power Isolator" available out there to accomplish this. N2k connected to engines has to isolate the power from the N2k network so that it powers with the engine (key switch on) and does not power on from the House 12V.
An N2k backbone is connected to +12V that is on with your House power.
Many devices like gps and sensors and GHC20s are even powered by N2k and will not work without it.Įdit: There is a quirk to connecting to engines though. Everything out there now uses N2k to share everything. Without that, you can connect to N2k but get slightly lesser functionality. Newer 7400 & up have J1939 and software specificaly for Yamama. The difference between J1939 and N2k is in the communication protocol that the Yamaha/Garmin use. See our warranty terms section on our website for details.The J1939 Yamaha adapter uses the same plug as NMEA2k. These cables come with a two year free, no questions asked replacement warranty. This will give you NMEA 0183 output from the NMEA 2000 network, and provide this data in the correct format to the Speedometer connection.
For them, the solution is our Better Connected™ Yamaha CommandLink Speedometer to NMEA 2000 Network Adapter Cable. Some fish finders, such as the Raymarine Element series, do not have an NMEA 0183 output.
Just give us a shout if you need information on compatibility. We’re always pleased to talk to customers if they are not certain about connections. But the color can vary widely from one manufacturer to the other. This is usually blue and white wires in an extra cable. It also provides connection for fuel sender level display from up to two fuel tanks/sending units.Ĭompletely identical with Yamaha Part Number 6Y8-8356N-01-00, but we have added a few more inches of wire length to help you out with the installation.īefore ordering this cable, you need to check if your fish finder / chart plotter / GPS has an NMEA 0183 output. This cable provides the connections from your fish finder / GPS / chart plotter to a newer Yamaha CommandLink 6Y8 Series Speedometer (round or square version).
