1.1 Introduction
Congratulations on your purchase of the Maretron EMS100 Engine Monitoring System.
Maretron has designed and built your engine monitoring system to the highest standards for
years of reliable, dependable, and accurate service.
The EMS100 plugs directly into engine wiring harnesses (through the use of a Maretron wiring
harness, purchased separately) and converts analog signals such as water temperature and
oil pressure to the NMEA 2000
throughout the vessel over a single cable where it can be monitored by any NMEA 2000
compatible display. 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
traditional analog instrument panel.
The Maretron EMS100 is designed to operate within the harsh demands of the marine
environment. However, no piece of marine electronic equipment can function properly unless
installed, configured, and maintained in the correct manner. Please read carefully and follow
these instructions for installation, configuration, and usage of the Maretron EMS100 in order to
