  1. questionUsing the N2KAnalyzer how do I recover a device?
    The N2KAnalyzer software can restore a devices software using the following method: Select the affected device(represented by a row with light gray serial number shown), right-click to highlight the row, select "Update selected device software". A window will prompt you to enter the device' ...

  2. questionWhat firmware changes have taken place on the Maretron DCR100?
    What firmware changes have taken place on the Maretron DCR100? Update your device today using the N2KAnalyzer software tool. DCR100 Firmware Versions 1.1.2.3(2013-07-19) -Removed support for the deprecated 127502 Switch Bank Control parameter group -Added support for hardware timers and counters ...

  3. questionThe DCR100 will not allow me to switch on/off a relay channel, why?
    The DCR100 has a DC current calibration option. If you have connected a DC load to a channel of the DCR100 and have not set the Zero, this may affect the command of this channel especially if the DCR100 detects a negative DC current value to load. You can set the DCR100 "Current Sensor Zero Offs ...

  4. questionCan I use the DCR100 to switch AC loads?
    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. Any relay can be used to switch an AC load as shown in the illustration below. The illustration below shows a SSR (opto22) used to switch AC loads.

  5. questionWhat are the Voltage specifications for each Maretron device?
    Maretron Model Device Description NMEA2000 Operating Voltage Engine/Battery Interface SSC200 NMEA 2000 Solid State Compass HW 1.0 9 to 16 Volts USB100 NMEA 2000 / NMEA 0183 Gateway 9 to 16 Volts DSM200 NMEA 2000 Multi-function Display 9 to 16 Volts GPS100 NMEA 2000 GPS Antenna / ...

  6. questionWhat type of solderless connector is ideal for mating sensor wire to Maretron multi-channel products?
    A #4 Nylon Double-Crimp Insulated Ring Terminal( P/N:WT-651045) is the ideal choice when connecting sensor wire to any of Maretron's multi-channel devices. The following link provides a great color selection to choose from: http://www.wiringproducts.com - Mike Voorhees from Yacht Masters ...

  7. questionCan I use the DSM250 to configure a DCR100?
    Yes, you can use a DSM250 to configure a DCR100. Please watch the following video to see how it’s done.

  8. questionCan I use the DCR100 to detect burnt out lights or burnt out loads?
    Yes, you can use the DCR100 in conjunction with Maretron's display products (e.g., N2KAnalyzer 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 and manually observe when the current is zero and the ...

  9. questionIn addition to switching On and Off DC loads, can I use the DCR100 to monitor current flow to the loads?
    Yes, you can use the DCR100 to monitor DC current flow to loads using one of Maretron's display products (e.g., N2KView or DSM250). Each of the six channels within the DCR100 reports how much current is flowing to the load, which is useful for several reasons. For example, if a circuit is switch ...

  10. questionCan I turn On and Off loads connected to the DCR100 using the DSM250?
    Yes, you can turn On and Off loads connected to the DCR100 using the DSM250. To do so, you should understand a few things about the DSM250 and its favorite screens. First, you need to understand how to setup a favorite screen within the DSM250 and second, you need to understand how to place t ...

  11. questionWhat is a DCR100?
    Maretron's DCR100 contains 6 Direct Current (DC) relays, each capable of switching up to 10 Amps at 12VDC or 24VDC. The DCR100 connects directly to an NMEA 2000® network, so you can turn on and off the relays from a Maretron DSM250 display or any device onboard or remotely running Maretron&# ...

  12. questionDoes the DCR100 provide over current circuit protection?
    No, the DCR100 does not provide over current circuit protection. The DCR100 contains six Solid State Relays (SSRs), which need to be individually over current protected using an external method (e.g., circuit breakers or fuses). The following diagram shows the individual SSRs within the DCR100 p ...

  13. questionDo the Solid State State Relays (SSRs) within the DCR100 turn off if the NMEA 2000 power is removed from the DCR100?
    Yes, the SSRs within the DCR100 turn off if the NMEA 2000 power is removed from the DCR100. Once NMEA 2000 power is reapplied to the DCR100, the individual SSRs will return to the state that they were in at the time power was removed. In other words, the DCR100 remembers whether each SSR was On ...

  14. questionIs it possible to wire a manual override switch around the DCR100?
    Yes, you can use a manual switch to override the DCR100. Please see the attached diagrams which shows three different circuit configurations. The first circuit diagram shows how the DCR100 is wired into a circuit without any type of manual override. With this configuration, the light is con ...
