  1. What is an SSC200? The Maretron SSC200 is a solid state, magnetic compass that is capable of measuring heading, pitch, roll, and rate of turn. The information is broadcast over an NMEA 0183 connection or an NMEA 2000 network where the information is available for any o... Read More
  2. Why is the SSC200 compass better than other marine compasses that use fluxgate technology? The SSC200 compass is better than other marine compasses that use fluxgate technology because there are no moving parts in the SSC200. Compasses using fluxgate technology have a coil floating in a liquid, and once this coil is set in motion (vessel i... Read More
  3. What information does the SSC200 compass provide? The SSC200 compass provides the following information:magnetic headingrollpitchrate of turn... Read More
  4. What messages (or PGNs) does the SSC200 transmit? The SSC200 compass transmits the following messages (or PGNs):PGN 127250 - Vessel Heading (Fields: 1-SID, 2-Heading Sensor Reading, 3-Magnetic Heading Correction 4- Magnetic Heading Correction 5-Heading Sensor Reference)PGN 127251 - Rate of Turn (Fie...

  5. Why doesn’t the SSC200 compass transmit true heading? The SSC200 is a magnetic compass, which means that it measures the direction of Earth's magnetic field relative to the magnetic poles (magnetic heading). This is different than a gyrocompass, which measures heading relative to the Earth's r... Read More
  6. I navigate using magnetic heading and not true heading; how do I use the SSC200 compass and Maretron’s DSM150, DSM200, or DSM250 display to view my heading in magnetic? The SSC200 compass outputs heading information in magnetic format, so you just need to properly configure the DSM150, DSM200, or DSM250 to display heading in magnetic. To view magnetic heading on the DSM150, DSM200, or DSM250, do the following:Enter ... Read More
  7. I navigate using magnetic heading and not true heading; how do I use the SSC200 compass and N2KView software to view my heading in magnetic? The SSC200 compass outputs heading information in magnetic format, so you need to properly configure N2KView to display heading in magnetic. To view magnetic heading within N2KView, click on the "Units Setup" tab, and select "Magnetic from the "Headi... Read More
  8. I navigate using true heading and not magnetic heading; how do I use the SSC200 compass and N2KView software to view my heading in true? The SSC200 compass outputs heading information in magnetic form and before N2KView can display true heading, the variation must be known. One source of variation is the Maretron GPS antenna/receiver (GPS200). If an SSC200 and GPS200 are connected tog... Read More
  9. How do I display the SSC200 magnetic heading on Maretron’s DSM150, DSM200, or DSM250 display? You display the SSC200 magnetic heading information on a DSM150, DSM200, or DSM250 in the following way:Enter menu mode, scroll to "Favorite Screen Setup..." and press < Enter >Scroll to the favorite screen where you would like to view the magnetic h...

  10. Why does the heading coming from the SSC200 appear to be in error? The SSC200 measures the Earth's magnetic field and before it will provide an accurate heading, it must understand how the Earth's magnetic field is affected (or deviates from normal) due to the ferrous metals found on the vessel. Fortunatel... Read More
