Maretron introduced their J2K100 gateway, which attaches directly to SAE J1939 networks of compatible engines and transmissions and converts the SAE J1939 engine data to the NMEA 2000 marine digital interface. Critical engine, transmission, and genset data are distributed throughout the vessel over a single cable, which any NMEA 2000® compatible display can monitor. All the information you need is available anywhere, and everywhere you need it. 

The J2K100 only listens to the SAE J1939 network and draws no power from it (derived from the NMEA 2000® interface). The J2K100 does not transmit any information over the SAE J1939 network, so it will not interfere with existing engine control or status data in any way. 

The J2K100 can also be used as part of a complete fuel computer. Connect the J2K100 with Maretron universal displays (DSM Series, N2KView®) and GPS antenna/receiver (GPS200), and you have a system capable of displaying gallons per hour and/or miles per gallon.

The Maretron J2K100 is designed to operate within the harsh demands of the marine environment.

SAE J1939 ECU Simulator Board With USB Port

The jCOM.J1939.USB gateway board is a high-performance, low-latency vehicle network adapter for SAE J1939 applications. It allows any host device with a USB COM port to monitor SAE J1939 data traffic and communicate with the SAE J1939 vehicle network.

The board supports the full SAE J1939 protocol according to J1939/81 Network Management (Address Claiming) and J1939/21 Transport Protocol (TP). It is also supported by an extensive programming interface for Windows and Linux/Ubuntu applications, including full C/C++/C# source code for short time-to-market developments.

In addition, the gateway is supported by our jCOM1939 Monitor, an SAE J1939 Monitoring, Analyzer and ECU Simulation software under Windows.
