Maretron J2K100 NMEA 2000 / J1939 Bridge

The Maretron J2K100 NMEA 2000® / J1939 Bridge is an essential component for marine enthusiasts seeking to integrate their engine, transmission, and genset data seamlessly into a unified digital monitoring system. Designed for compatibility with a wide range of marine engines, this bridge directly connects to your vessel's J1939 networks, translating vital engine data into the NMEA 2000® marine digital interface. This integration allows for centralized monitoring across multiple display units on your boat, enhancing situational awareness and operational efficiency.

Seamless Integration with Your Marine Systems

The J2K100 bridge is engineered to attach effortlessly to existing J1939 networks of compatible marine engines, transmissions, and gensets. By converting J1939 data to the NMEA 2000® standard, it facilitates the distribution of critical engine information through a single NMEA 2000® cable. This streamlined connectivity ensures that key performance indicators are accessible from any NMEA 2000® compatible display, providing you with real-time insights wherever you are on your vessel.

Power-Efficient and Non-Intrusive Design

Designed with efficiency in mind, the J2K100 derives power directly from the NMEA 2000® interface, eliminating the need to draw power from the J1939 network. This ensures that the bridge operates without placing additional load on your engine's systems. Furthermore, the J2K100 is a passive device on the J1939 network; it only listens to the data traffic without transmitting any information back. This non-intrusive operation guarantees that existing engine control and status data remain unaffected, maintaining the integrity and reliability of your vessel's systems.

Expand Your Monitoring Capabilities

The versatility of the J2K100 extends beyond data conversion. When combined with the Maretron DSM200 universal display and the GPS100 antenna/receiver, the J2K100 forms a comprehensive fuel computer system. This setup enables precise monitoring of fuel consumption rates, displaying data such as gallons per hour and miles per gallon. This capability is invaluable for managing fuel efficiency and optimizing vessel performance during extended voyages.
