What firmware changes have taken place on the Maretron DCR100 Relay Module? You can update your device using the N2KAnalyzer software tool.   DCR100 Firmware Versions 1.1.2.3 (2013-07-19) Removed support for the deprecated 127502 Switch Bank... Read More

DCR100 channels have two possible operating modes: “Normal”, in which the DCR100 channel responds to standard NMEA 2000 switching commands, and “Annunciator”, in which the channel may be connected to a power source for a... Read More

Yes, The DCR100 can control your audio amplifier by way of the “Remote” input to the amplifier. For vessels with large audio networks an N2KView user can use this feature to selectively control audio amplifiers by way of a single or... Read More

Maretron displays perform switching (on/off) of the solid-state relays in the DCR100 via the NMEA standard method of using an NMEA Command (PGN 126208) of the 127501 Binary Switch Bank Status message. The Switch Bank Indicator field, along with the... Read More

The DCR100 has a DC current calibration option. If you have connected a DC load to a channel of the DCR100 and have not performed the "Current Sensor Zero Offset Calibration", this may affect the command of this channel especially if the DCR100... Read More

The DCR100 offers two types of channel configuration: relay annunciator The annunciator configuration allows for N2KView to command a DCR100 channel to close a relay when an alert is configured to have an action,as shown in Figure 1 below.Figure 1... Read More

Yes, you can use the DCR100 in conjunction with Maretron's display products (e.g., N2KView, DSM150, or DSM250) to detect burnt out loads. You can do this in one of two ways; 1) setup a favorite screen to monitor the DC current for a particular load... Read More

You can not use the DCR100 to directly switch AC loads, but you can use the DCR100 with an external relay to turn On and Off AC loads.- A Solid State Relay (SSR) can be used to switch an AC load as shown in the illustration below. Read More

Yes, you can use the DCR100 to monitor DC current flow to loads using one of Maretron's display products (e.g., N2KView, DSM150, or DSM250). Each of the six channels within the DCR100 reports how much current is flowing to the load, which is useful... Read More
