Most modern electronic engines have a digital interface called J1939. Maretron’s J2K100 is a gateway that converts the J1939 protocol to marine industry standard digital protocol called NMEA 2000. The J2K100 converts many engine parameters including RPM, boost and oil pressure, oil and coolant temperature, voltage, fuel rate, engine hours and more depending on the particular engine.
The following table shows the products included within this example system plus a list of the information or data available for display.
| Product | Description | Available Data List |
| DSM410 | Display | Displays data in this list, monitors the data and sounds an internal buzzer if there is a problem |
| J2K100 | Engine Monitor | Monitors RPM, boost and oil pressure, oil and coolant temp, voltage, fuel rate, hours, and more depending on the particular engine |
This file requires Maretrons free NMEA 2000® network design tool N2KBuilder® to be installed on your PC.
