Engine Monitoring Unit

The Actisense EMU-1 is a specialised analogue to NMEA 2000 Gateway which converts data from analogue engine senders into NMEA 2000 (please refer to FAQ #9 for sender/gauge compatibility details). The EMU-1 enables NMEA 2000 display devices to monitor the engine on a vessel.

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. Capable of measuring a wide range of engine parameters, the EMU-1 reports how the engine is operating and shares the information across the network.

Designed to simplify the conversion of analogue engine parameters (e.g. Temperature, pressure and RPM) into NMEA 2000 engine PGNs, the EMU-1 simplifies processes and reduces the number of input/output wires required at each engine. Additionally, the EMU-1 also supports the conversion of analogue transmission parameters and battery status to the associated NMEA 2000 PGN's.

Now available with the SeaTalk NG 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.

The two-part screw terminal connection system allows for an easy pluggable connection to an engine wiring harness.

The EMU-1 can monitor two engines where each engine has three (or less) gauges that require monitoring. Where dual engines have more than three gauges each to monitor, multiple EMU-1 units are required.

Alternatively, the EMU-1 can be used to monitor fluid levels in up to six tanks at any one time. The addition of a configurable 'instance' for each tank allows the user to identify which tank the data is coming from.

The customised case ensures that the electronics are sealed while allowing quick access to the electrical connections.

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.

It is recommended that an Actisense NGT-1 NMEA 2000 PC Interface is available for every EMU-1 installation. The NGT-1 can be used to update the Firmware, connect the Configuration Tool and display data on a PC for diagnostic and information purposes, using NMEA Reader.
