SSC200 Firmware Versions

  • Correct Gyro Offset Table Issue (2463)
  • Increase the acceptable error range of Gyro Temperature Offset to 15 degree C (2666)




  • Re-Enabled "store baud command" for 0183 configurations.
  • Hardware improvements 


3.0.2 (2010-05)

  • Corrected issue when 0° would display when heading was truly 180°

3.0.1 (2010-04-23)

  • Increased maximum heading (PGN 127250) transmission rate from 10Hz (100ms) to 40Hz (25ms)


2.0.11 (2009-03-04)

  • Added support for labeling so that the device can easily be identified with a user-programmable string


2.0.10 (2008-03-03)

  • Fixed problem where the device tried to transmit a PGN before it had acquired a node address


2.0.9 (2007-08-30)

  • Corrected a problem with programming of installation offset


1.10.2, 2.0.2 (2006-01-31)

  • Support deviation for calibration ignoring accelerometers (“No Acc”) for calibration on large vessels


1.10.1, 2.0.1 (2005-10-03)

  • Send sequence of headings 0 degrees, 90 degrees, 180 degrees, 270 degrees for one second each after successful magnetic deviation calibration


1.10.0, 2.0.0 (2005-09-09)

  • Added support for OEM product versions
  • Updated supported NMEA 2000 protocol version to 1.2
  • Added support for inverted and backwards installation


1.9.2 (2005-07-14)

  • No user-visible changes (manufacturing improvements)


1.9.1          (2005-07-07)

  • No user-visible changes (manufacturing improvements)


1.9   (2005-05-13)

  • Added ability to configure rate of transmission of NMEA 2000 messages
  • Added support for 40Hz operation on NMEA 0183
  • Added ability to report status of magnetic deviation
  • Added ability to perform rate of turn zero offset calibration
  • Correct the automatic selection of magnetic variation sources when multiple are available


1.8   (2005-03-11)

  • Added the capability to have NMEA 0183 sentences enabled or disabled from a DSM200 or DSM250 display
  • Added ability to automatically receive magnetic variation from either NMEA 2000 or NMEA 0183 interfaces
  • Fixed a heading error when heading changes between 180 and 179 degrees
  • Added the capability to be programmed with a manual magnetic variation entry for use when no variation data is available from other devices
  • Changed to always use the best quality source of magnetic variation when multiple sources are available
  • Changed to not require a checksum on received NMEA 0183 sentences
  • Updated supported NMEA 2000 protocol version to 1.111
  • Changed averaging periods on rate of turn and heading

 1.7   (2005-04-02)

  • Modified NMEA 0183 sentences HDG,HDM,HDT to add leading zero to all heading related fields so that they display in the "xxx.x" format
  • Made the NMEA 0183 sentences VTG and RMC backward compatible to NMEA0183 2.01 (ignore mode indication field if this field does not exist)
  • Made the NMEA 0183 device identifier programmable

 1.6 (2005-01-21)

  • Initial public release
