  2. How can I tell if an engine or engine network requires a Maretron Gateway such as the J2K100 or a Network Bridge? Generally, marine engine CAN bus networks have one of two popular types of protocols:J1939NMEA 2000Most outboards offered since about 2006 support NMEA 2000 natively. Maretron always recommends first contacting the engine manufacturer to determine wh... Read More
  3. What is a J2K100? The J2K100 is a gateway or bridge between a J1939 network and an NMEA 2000 network. The J2K100 receives messages (or PGNs) from a J1939 network and converts the messages into NMEA 2000 messages (or PGNs). In some cases, J1939 messages are the same as... Read More
