Maretron's J2K100 attaches directly into J1939 networks of compatible engines, transmissions, and gensets and converts the J1939 engine data to the NMEA 2000^® marine digital interface. Critical engine, transmission, and genset data is then distributed throughout the vessel over a single cable where it can be monitored by any NMEA 2000^® compatible display. All the information you need is available anywhere and everywhere you need it.

The J2K100 only listens to the J1939 network and draws no power from it (power is derived from the NMEA 2000^® interface). The J2K100 does not transmit any information over the J1939 network so it will not interfere with existing engine control or status data in any way.

The J2K100 can also be used as part of a complete fuel computer. Simply connect the J2K100 together with the Maretron universal display (DSM150 or DSM250) and GPS antenna/receiver (GPS200) and you have a system capable of displaying gallons per hour and/or miles per gallon.
