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 EMU-1 when using a single unit for two engines or multiple EMU-1 on the same NMEA 2000 network...
