A-EMU-1-BAS Engine Monitoring Unit

A-EMU-1-BAS Engine Monitoring Unit

ACTISENSE

$625.00

A-EMU-1-BAS Engine Monitoring Unit, Analogue to NMEA 2000

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.
