3.0.2 (2010-05-28)

- Corrected a problem where a heading of 0° was occasionally mistakenly output when actual heading was 180°. This could be seen by a "flipping" of a course-up display using the SSC200 as a heading reference.

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
