  1. I would like to see NMEA2000 Engine and Transmission warnings on my N2K network, what J1939 diagnostic codes will the J2K100 convert? The J2K100 will convert J1939 Diagnostic SPN/PGNs to NMEA2000 Engine and Transmission Warning messages. Consult the engine manufacturer to determine if an engine will transmit these messages over the NMEA2000 bus.The following table (figure 1) provid... Read More
  2. Can the J2K100 convert Volvo-Penta engine data to NMEA2000? Yes, a J2K100 can be used to convert a Volvo Penta standard J1939 messages to NMEA2000.  Prior to a purchase of a J2K100(Per engine) examine the existing cabling provided by the engine manufacturer. Engines with EVC, EDC systems can be connected to t...

  3. How do I connect a Maretron Field Makable Connector or Field Attachable to an NMEA2000 Cable? The heart of the NMEA2000 system is the cabling infrastructure and it is vital that field connections are made correct to avoid damage to sensors or non-intelligent components such as tees, multi-ports, power-taps. Maretron offers four types of Field... Read More
  4. Can I install more than one SMS100 in the same NMEA 2000 network? No, an NMEA 2000 network can only contain a single SMS100.... Read More
  5. How do I make a custom NMEA 2000 cordset cable? Does Maretron offer a field attachable connector? Maretron offers several accessories that allow you to make a custom NMEA 2000 cable.It may be necessary to make a custom cable for the following reasons:Cable runs longer than 10m in lengthRouting raw cables micro/mid through bulkheads, wire trays, a...

  6. Is there a list of NMEA 2000 messages (a message is identified by a Parameter Group Number, or PGN)? Yes, the National Marine Electronics Association (NMEA) publishes a list of PGNs, which can be found via this link:  ... Read More
  7. I want to update my NMEA 2000 network to include fuel management data; which Maretron devices do I need? The FFM100 can update your existing NMEA2000 network to include engine fuel rate. Several components are needed to offer you calculative information for Fuel management such as distance to empty, time to empty, and fuel consumption, to name a few.  T... Read More
  8. Do the Solid 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. By default, 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 ... Read More
  9. How do I transfer display settings from one DSM150 or DSM250 to another DSM150 or DSM250 on the same NMEA 2000 network? The DSM250 has the ability to clone its settings to another DSM250 display on the same NMEA2000 network. For example if you want one DSM250 in one part of the ship to have the same settings at the helm DSM250 follow these simple steps.Go to the DSM25... Read More
  10. How do I know how much current an NMEA 2000 product will draw from the network? Manufacturers of NMEA 2000 equipment are required to disclose the amount of current drawn from the NMEA 2000 network. The amount of current used from the network is expressed as a Load Equivalence Number (LEN) where each LEN is equal to 50mA. For exa... Read More
