  • $ 541.98 USD


Actisense - EMU-1-BAS - NMEA 2000 Engine Gateway

Engine Monitoring Unit, Analogue to NMEA 2000, standard configuration.

EMU-1 User Manual Issue 1.06

EMU-1 Data Sheet issue 4.00

The Actisense EMU-1 is a specialised analogue to NMEA 2000 Gateway which converts data from analogue engine gauges/senders into NMEA 2000 data.
Find out if the EMU-1 works with your engine

New features and updates will be added to the Actisense Toolkit (the EMU-1 Configuration Tool) on a regular basis. Please check you are using the latest version of Toolkit and EMU-1 firmware by going to the Downloads page. All EMU-1 firmware updates are part of the Toolkit software.

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 (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.

The EMU-1 is available with the SeaTalkNG to NMEA 2000 adaptor Cable - STNG-A06045
The SeaTalk NG to NMEA 2000® adaptor cable (STNG-A06045) is not available as a standalone product and must be bought as part of a bundle.

An optional DIN rail mounting kit is also available. The kit is suitable for use with a top hat rail, type EN 50 022 or a G section rail, type EN 50 035. Please order the DIN rail kit using part number: DIN-KIT-1.
