The Maretron J2K100 converts data from J1939 engine networks to NMEA 2000 so engine parameters and fuel information are available across your vessel; when paired with Maretron DSM displays and a GPS200 antenna it can show fuel rate and efficiency in litres per hour (gallons per hour) and kilometres per litre (miles per gallon).

• Protocol conversion: maps J1939 PGNs to NMEA 2000 PGNs
• Common data types: engine speed, fuel rate, coolant temperature, oil pressure, battery voltage
• Works with DSM250, N2KView and GPS200 for fuel-economy readouts
• Connects to your NMEA 2000 network for plug-and-play integration (Micro‑C compatible)
• LED status indicators for quick diagnostics
• Compact, sealed marine enclosure suitable for engine spaces
• Configurable PGN mapping and filtering via N2KView
