Maretron RIM100 1 Introduction

1 Introduction

Congratulations on your purchase of the Maretron Run Indicator Module (RIM100). Maretron

has designed and built your RIM100 to the highest standards for years of dependable and

accurate service.

Maretron’s RIM100 monitors both AC and DC electrical circuits and reports, over an NMEA

2000® network, whether or not the electrical circuit is energized and running. The RIM100

works equally as well for monitoring manually switched loads (e.g., running lights, anchor

lights, or deck lights) as it does for automatically switched loads. Monitoring automatically

switched loads (e.g., bilge pumps, engine exhaust/intake fans, and transfer pumps) via the

RIM100 is especially useful because you know exactly when equipment is, or isn't running.

The Maretron RIM100 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 RIM100 in order to

ensure optimal performance.

This manual corresponds to RIM100 firmware revision 1.0.2.
