1 Introduction
Congratulations on your purchase of the Maretron DC Monitor (DCM100). Maretron has
designed and built your DC monitor to the highest standards for years of dependable and
accurate service.
Maretron’s DCM100 is a device which monitors DC power sources or batteries and outputs
information about these sources onto the industry standard NMEA 2000
®
marine data network
so that these data can be monitored with networked NMEA 2000
®
displays such as the
Maretron DSM250 or with NMEA 2000
®
compatible software such as Maretron N2KView.
The Maretron DCM100 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 DCM100 in order to
