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. The process for this will be different from each manufacturer to the next, so please check with the manufacturer of your MFD for instruction on how to do this.
If you have checked the configuration settings, the next thing that you can do is use your NGT-1 with our NMEA Reader software to check if the NMEA 2000 messages (PGNs) are being transmitted to the network from your EMU-1.
Details on the process of using NMEA Reader and a further explanation can be found here: https://www.actisense.com/knowledge-base/nmea-2000/emu-1/data-not-displayed-from-emu-1/
