Yacht Devices YDOD-01 Engine Gateway NMEA Sensor

The Gateway is designed for petrol engines without digital interfaces, and provides NMEA 2000 equipment with engine revolutions (RPM), alternator voltage (measured at the NMEA 2000 interface) and engine hours. It can also be programmed to use data from NMEA 2000 temperature or pressure sensors and send these data as coolant and oil pressure or temperature, boost or fuel pressure.

To connect the Gateway, you only need to connect it to the NMEA 2000 backbone and make 4-5 turns of its wire around the spark plug wire, and affix the loops with tape. In most cases, no additional settings are required, but you might need to set the RPM divider according to the ignition system and type of your engine.
