J2K100 gateway between your engine's J1939 network and your boat's NMEA 2000 system displays critical information about your engine.Maretrons 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 FeaturesNMEA 2000 and J1939 InterfacesWaterproof connectorsSealed waterproof (IP67-rated) enclosureTranslates J1939 engine and transmission messages to equivalent NMEA 2000 messagesCapable of passing J1939 diagnostic messagesPasses J1939 AC generator parameters through to the NMEA 2000 networkJ1939 Interface is opto-isolated from NMEA 2000, eliminating potential ground loopsObtains 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 networkInterfaces Dometic Eskimo icemalers to NMEA 2000 networkThe J2K100 is waterproof, so it can be mounted in a damp or dry locationThe orientation is not important, so the J2K100 can be mounted on a horizontal deck, vertical bulkhead, or even upside down if desiredThe J2K100 is temperature rated to 55C (130F), so it should be mounted away from engines or engine rooms where the operating temperature exceeds the specified limitFunctions Monitored by the J2K100The J2K100 converts the following information:AC Generator CurrentAC Generator FrequencyAC Generator VoltageTachometerEngine HoursCoolant PressureCoolant Water
