  1. What is a powertap? Every NMEA 2000 network requires a power source, which is usually supplied by a powertap. The powertap is used to energize the 12 volt power and ground wires found within the NMEA 2000 cable.... Read More
  2. What is the maximum current that a single device may draw from an NMEA 2000 network? The maximum allowable current that a device is allowed to draw from the NMEA 2000 network is 1 ampere. Devices requiring more than 1 ampere of current use a separate power supply connection, which is required to be isolated from the NMEA 2000 power s... Read More
  3. How is the Mini Powertap wired? The Mini Powertap has 4 connection points. There are two 5-pin connectors on opposite sides of the powertap that are used as the NMEA 2000 bus connections (marked "BUS"), there is a 4-pin connector on the bottom of the powertap that is used as the po...

  4. Can I use the RIM100 to indicate "Water In Fuel"? The RIM100 can be used to monitor a Parker/Racor "Water-In-Fuel Detection Kit" (Part Number RK30880E) to indicate the presence of water in the fuel filter.First, make sure the RK30880E is properly connected and working (see attachment for wiring diag...

  5. What is the maximum voltage the DCM100 can sense? The DCM100 can sense voltages up to 50VDC on terminals 5 and 6.The maximum voltage that can be supplied to power the DCM100 on is 32VDC on terminals 7 and 8.Pin NumberSignal NameConnection1IACurrent Sensor, Red Wire2IBCurrent Sensor, Green Wire3ICCur...

  6. Can the J2K100 connect to third party protocol converters that support J1708 or J1587? Maretron's J2K100 attaches directly into J1939 networks of compatible engines, transmissions, and gensets and converts the J1939 data to NMEA 2000. For engines that offer protocols such as J1708 or J1587, users may choose to translate the engine... Read More
  7. What does Maretron recommnend to determine whether coolant water is supplied to my engine when running? Using a RIM100 channel, you can tell whether water coolant flow is feeding to the engine when the engine is running. Is some cases, the user is unaware that water is not cooling the engine until it is too late. This method below allows for an early w... Read More
  8. How do I change my N2KView operating mode? You can configure alerts to operate in one of several operating modes:Disabled – All alerts are disabled. This mode should be used when the vessel is in storage, drydock, or otherwise out of operationMoored - This mode is used when the vessel is secu... Read More
  9. How close can I install wires to the SSC200 before I start adversely affecting the compass? Small wires carrying small currents (less than 1 amp) should be kept at least 18 inches away from the SSC200 and even further if practical, while larger wires with large currents need to be even further away from the compass. Additionally, after the ... Read More
