  1. What configuration options are available for the FPM100? You can use the N2KAnalyzer software program or a Maretron DSM150, or Maretron DSM250 to perform the configuration. This article will show methods for configuring the FPM100 Using Maretron's N2KAnalyzer software tool. Pre-requisits:PC with N2KAn... Read More
  2. What information is available from the fluid pressure monitor (FPM100) and can be viewed on Maretron’s displays?  The FPM100 is capable of transmitting the following information: Pressures:Atmospheric PressureWater PressureSteam PressureCompressed Air PressureHydraulic PressureUser Defined 129 to 144Tank Types:Fuel Level, CapacityFresh Water Level, CapacityWast...

  3. I see that the FPM100 has an accessory for measuring pressures in the range of -1Bar to 1 Bar. Can I use this sensor to monitor my fuel filters? Yes, the FPM100 can transmit vacuum pressure data on the NMEA2000 bus by using Maretron sensor part number PT-V-0-1BAR-01. This sensor must be installed on the vacuum side of your fuel filter to help you determine fuel filter health displayed on a Ma...

  4. Is the FPM100 compatible with non-Maretron 4-20 mA pressure transducers? Maretron highly recommends using Maretron pressure transducers to achieve the specified accuracy; However, the FPM100 will support other linear 4-20mA transducers even though Maretron can't guarantee overall system accuracy.The 4-20mA sensor mus...

  5. What firmware changes have taken place on the Maretron FPM100? 1.0.2.2 (2014-10-31)Added support for real-time display of current readings during calibration1.0.1 (2011-11-03)Initial Release ... Read More
  6. Why do some of the FPM100 pressure transducer accessories have a small plastic tube within the cable? Some pressure transducers measure gauge pressure (pressure above atmospheric). These transducers have a small plastic vent tube enclosed in the connecting cable. Special care must be taken not to block or kink the vent tube, and not to expose the ven... Read More
  7. Using N2KAnalyzer, how do I recover a Maretron device? Occasionally, a device can be in "boot mode" (represented in N2KAnalyzer by an orange highlight of the device's entry in the device list). This can happen due to a software update which fails due to network problems.A Maretron device that is not... Read More
