Product Details

NMEA 2000 Engine Monitoring Unit - Analog to NMEA2000 Engine Gateway

Share engine information on the NMEA 2000 bus.

The Actisense EMU-1 is a specialized analogue to NMEA 2000 Gateway which converts data from analogue engine gauges/senders into NMEA 2000 data. The EMU-1 enables the sharing of engine data throughout the NMEA 2000 bus. It digitizes analogue engine sensors, enabling NMEA 2000 display devices to monitor the connected engine(s) on a vessel.

The EMU-1 can monitor vital engine parameters such as temperature, pressure RPM and fluid levels from up to two engines.

The EMU-1 has a PC-based configuration tool that allows the settings inside the EMU-1 to be changed to best suit the engine it is working with, making it a flexible solution for many engine makes and models.

An Actisense PC to NMEA 2000 Gateway (NGX-1/NGT-1) is required to configure the EMU-1.

The NGX-1 or NGT-1 must be used to update the firmware, connect the Toolkit and display data on a PC for diagnostic and information purposes, using NMEA Reader. Please visit the NGX-1 page and/or NGT-1 page for product details.

Features:

  • Enables analogue signals to be converted to NMEA 2000 messages
