When the gauges are to remain in-circuit, the EMU-1 has to be powered from the same supply that is powering the gauges for the engine that it is monitoring. The best way to do this is to wire directly from the back of the positive and GND terminal on the back of the gauge closest to the EMU-1. If the EMU-1 is used to replace the gauges, it will automatically take over the powering of the senders and can be powered as is convenient. Full wiring instructions for the EMU-1 can be found in the EMU-1 User Manual available on our website.
When using a single EMU-1 with two engines, the engines and their senders/gauges must share a common ground.
Data not displayed from EMU-1
When the engine information you were expecting from the EMU-1 isn't available on your Multi-Function Display (MFD), we recommend checking the configuration settings of your MFD to ensure it has been setup correctly to receive data from the EMU-1. ...
EMU-1 Engine Compatibility and Setup
In order to confirm that the EMU-1 will be compatible with your system, please identify the manufacturer of the gauges (VDO, Faria, US Marine, Yanmar etc...) and the range of values (40 to 140 degrees C, 0 to 5 Bar etc...). Once confirmed, refer to ...
Configuring The EMU-1 with more than 1 Engine
A single EMU-1 can be used to monitor up to two engines, so long as they both share the same power supply. For installations where this is not the case, a dedicated EMU-1 will be needed for each engine. This article will explain how to set up your ...
Converting Engine Data from NMEA 2000 to NMEA 0183
The conversion of Engine Data PGNs to NMEA 0183 sentences is very limited. Visit this article for more info: https://www.actisense.com/knowledge-base/hottest-articles/converting-engine-data-from-nmea-2000-to-nmea-0183/
NMEA 0183 device not receiving data from NGW-1
If your NMEA 0183 Listener is not showing any data when connected to the NMEA 0183 output of an NGW-1, the first step for fault finding should be to see if the NGW-1 supports the conversions you need. For more information on the steps taken when ...
