PRODUCT INFORMATION
EMU-1 NMEA 2000® Engine Monitoring Unit
EMU-1 - Convert your Analog engine data to NMEA 2000.
(Please note that an Actisense NGX-1-USB or NGX-1-ISO, is required to configure the EMU-1. This is an optional item and is not included with the EMU-1)
The Actisense EMU-1 is a specialized analogue to NMEA 2000 Gateway which converts data from analogue engine senders into NMEA 2000. 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.
The two-part screw terminal connection system allows for an easy pluggable connection to an engine wiring harness.
Multiple engines are supported by the setting of the engine instance using the EMU-1 configuration tool. Currently one EMU-1 per engine is supported. Support for multiple engines on a single EMU-1 is currently planned as a future firmware update.
The customized 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 NGX-1 NMEA 2000 Gateway is available for every EMU-1 installation as the EMU-1 can not be configured without one. The NGX-1 can also be used to update the Firmware, connect the Configuration Tool and display data on a PC for diagnostic and information purposes, using NMEA Reader. Please visit the Actisense Engine Monitoring Solution page for product details.
Now Includes Support for Tilt & Trim Tabs!
