The J1939 protocol is increasingly being adopted in marine applications, providing monitoring and control for engines, propulsion systems, generators, and electrical networks. To support this trend, a self-contained J1939 diagnostics tool has been developed, featuring a built-in web interface that allows any device with a browser to connect and analyze data seamlessly. With wireless connectivity to mobile devices, users can access critical information from anywhere on the vessel without the need for physical connections.

This diagnostics tool not only monitors the J1939 network but also checks its physical characteristics, including voltages, bus load, and frame errors. Users can view all devices connected to the network and drill down into specific data for detailed analysis. Its flexibility is enhanced by an M12 connector, which supports a wide variety of third-party patch cables and breakouts, making it compatible with diverse setups.

Easily monitor and manage device fault codes with our user-friendly interface. Click the Fault (Red Cross) icon to view active and historical codes in a clear pop-up. The DM1 Table displays the currently active fault codes, while the DM2 Table provides a record of historical faults.

If a fault condition remains active after clearing, the system automatically detects and displays it again during the next PGN transmission, ensuring you always have accurate, up-to-date diagnostic information at your fingertips.
