Description
Maretron J2K100 NMEA 2000/J1939 Bridge | Boat Supply Store
Integrate proprietary J1939 engine data into your universal NMEA 2000® network with the Maretron J2K100 bridge, enabling comprehensive monitoring of critical vessel systems without altering existing engine controls. This device converts J1939 engine, transmission, and genset data, including tachometer, engine hours, and various pressures and temperatures, to the NMEA 2000® marine digital interface. It seamlessly supports AC generator parameter monitoring and can be configured as part of an advanced fuel computer system when paired with a DSM200 display and GPS100 for precise fuel rate calculations, ideal for offshore fishing vessels off the Texas coast.
Key Features
- Seamlessly bridges J1939 engine data to the NMEA 2000® standard.
- Comprehensive monitoring of AC generator parameters, including current, frequency, and voltage.
- Detailed engine diagnostics displayed, such as tachometer, engine hours, and fluid pressures/temperatures.
- Accurate fuel rate monitoring for precise consumption analysis.
- Transmission data including gear, oil pressure, and temperature displayed.
- Non-intrusive operation, drawing power only from the NMEA 2000® network and not transmitting on J1939.
- Integrates with Maretron displays for enhanced fuel computer functionality.
- Prevents interference with existing engine control systems by not transmitting on the J1939 network.

Common Concerns Answered
Are all J1939 engine parameters supported by the J2K100?
The J2K100 supports a comprehensive list of common J1939 parameters, but may not cover every proprietary parameter offered by all manufacturers. It is recommended to verify specific parameter needs against the product's supported list.
Do I need additional components for full fuel computer functionality?
Yes, for full fuel computer functionality, the J2K100 requires integration with a Maretron DSM200 display and a GPS100. These components work in tandem to provide precise fuel management capabilities.
Can the J2K100 interfere with my engine's onboard computer?
No, the J2K100 is designed to be non-intrusive. It only listens to the J1939 network and does not transmit any data, ensuring it will not interfere with your existing engine control systems.
Frequently Asked Questions
What specific engine data can the Maretron J2K100 bridge display?
The J2K100 can display tachometer, engine hours, coolant pressure and temperature, oil pressure and temperature, boost pressure, fuel rate, percent engine torque, rated engine speed, VIN, and software ID, along with transmission gear, oil pressure, and oil temperature.
How does the J2K100 connect to J1939 and NMEA 2000 networks?
The J2K100 connects to the J1939 network via a standard J1939 harness and integrates into an NMEA 2000® network by connecting to a drop cable on the backbone.
Does the J2K100 draw power from the J1939 network?
No, the J2K100 exclusively draws its operating power from the NMEA 2000® network, eliminating the need for separate power wiring and preventing any power draw from the J1939 system.
Can the J2K100 be used as part of a fuel computer system?
Yes, the J2K100 is designed to be a key component of a Maretron fuel computer system when combined with a DSM200 display and a GPS100 for accurate fuel calculations.
What Maretron displays are compatible with the J2K100 for fuel computer functionality?
The Maretron DSM200 display is compatible with the J2K100 for enabling full fuel computer functionality when paired with a GPS100.
