Maretron J2K100 NMEA 2000® / J1939 Bridge – J2K100-01

Integrate your vessel’s engine and propulsion data into your marine electronics network with the Maretron J2K100 NMEA 2000® / J1939 Bridge (J2K100-01). This advanced interface bridges the J1939 CANbus used by many diesel and gasoline marine engines with the NMEA 2000® network, allowing critical engine parameters such as RPM, temperature, fuel rate, and alarms to be shared seamlessly with chartplotters, multifunction displays (MFDs), and monitoring systems.

Designed for professional marine installations, the J2K100-01 makes it easy to unlock rich diagnostic and performance data from engines, generators, and propulsion controllers that communicate over the J1939 standard. Once bridged to NMEA 2000®, this data becomes accessible to your marine network for display, logging, and alarm generation alongside navigation, tank, environmental, and other vessel systems.

Built by Maretron with rugged, waterproof connectors and marine-ready hardware, the J2K100 helps bring unified system visibility to complex engine setups, making it ideal for recreational vessels, commercial boats, and professional fleet applications.

Summary for the User

The J2K100 is an essential tool for modernizing an older helm. Instead of relying on analog dials, you can use this bridge to move all your engine data onto a single digital screen. It is highly reliable and virtually maintenance-free once configured.

Pro Tip: If you have twin engines, you will typically need one J2K100 per engine to properly map the data as "Port" and "Starboard" on your network.

WARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm. For more information go to P65Warnings.ca.gov.
