Product Overview

 J2K100 gateway between your engine's J1939 network and your boat's NMEA 2000 system displays critical information about your engine.

Maretron’s J2K100 attaches directly into J1939 networks of compatible engines, transmissions and gensets and converts the J1939 data to the marine digital interface (NMEA 2000). 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.

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) or DSM410 and GPS antenna/receiver (GPS200) and you have a system capable of displaying gallons per hour and/or miles per gallon.

Adapter for Caterpillar engines: The MCF-2M-D12CAT cable is designed to allow the J2K100 to have a parallel J1939 connection to the Caterpillar MPD display ONLY. Compatibility with other engine makes not supported.

Key Features

  • Sealed waterproof (IP67-rated) enclosure
  • Translates J1939 engine and transmission messages to equivalent NMEA 2000 messages
  • Capable of passing J1939 diagnostic messages
  • Passes J1939 AC generator parameters through to the NMEA 2000 network
  • J1939 Interface is opto-isolated from NMEA 2000, eliminating potential ground loops
  • Obtains power from NMEA 2000® port (No power drawn from or data transmitted on J1939 interface)
  • Interfaces Dometic MarineAir Elite and CruiseAir Q-Logic air conditioners to NMEA 2000 network
  • Interfaces Dometic Eskimo icemalers to NMEA 2000 network
  • The J2K100 is waterproof, so it can be mounted in a damp or dry location
  • The orientation is not important, so the J2K100 can be mounted on a horizontal deck, vertical bulkhead, or even upside down if desired
  • The J2K100 is temperature rated to 55°C (130°F), so it should be mounted away from engines or engine rooms where the operating temperature exceeds the specified limit
