"EMS100 - NMEA 2000® Engine Monitoring System
Maretron's EMS100 plugs directly into engine wiring
harnesses and converts analog signals such as water
temperature and oil pressure to the new marine
digital interface (NMEA 2000®). Critical engine data is then distributed throughout the vessel over a single
cable where it can be monitored by any NMEA 2000® compatible display. All the information you need is available anywhere and everywhere you need it.
The EMS100 is compatible with existing instrument panels
and key switches so you don't need to remove them while upgrading to newer digital technology. For new installations, the EMS100 and a compatible NMEA 2000® display can replace the traditional analog instrument panel."
