EMU-1-BAS Analogue Engine to NMEA2000 converter
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 digitises 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.

EMU-1 Engine Monitoring Unit
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 (NGT-1) is required to configure the EMU-1.
It is recommended that an NGT-1 is available for every EMU-1 installation. The NGT-1 can 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 NGT-1 page for product details.
