Connects J1939 to NMEA 2000 network

Maretron offers the J2K100 gateway, which can be attached to the J1939-based network of marine engines. On the other CAN interface it features NMEA 2000 (IEC 1162-3).

The gateway by Maretron collects J1939 engine data and forwards it to the NMEA 2000 connected display. It listens to the J1939 network and draws no power from it (power is derived from the NMEA 2000 interface). The product 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 gateway can also be used as part of a fuel computer; just connect it together with the display (DSM150, DSM250, or DSM410) and GPS antenna/receiver (GPS200). This system is capable of displaying gallons per hour and/or miles per gallon. The gateway can also read other parameters from the engine network, e.g. transmission gear, engine oil pressure, and AC generator voltage/current.

CANopen-to-NMEA 2000 gateway
In maritime electronics, some companies use CANopen networks. For such applications, ADFweb offers a gateway to NMEA 2000 networks. The HD67250 converts CANopen process data into NMEA 2000 messages and vice versa. The product is also available in a robust metal housing. This version is resistant against shocks and vibrations. The temperature is specified from -40 °C to + 105 °C.
