5. Continue turning the vessel through at least 3 circles until you see one of the following
Maretron proprietary sentences:
a. $IITXT,01,01,02,Deviation Calibration Successfully Completed*17<CR><LF> This
sentence indicates a successful calibration and you can jump to step number 6.
b. $IITXT,01,01,03,Deviation Calibration Failed To Complete*43<CR><LF> This
sentence indicates that the calibration failed (return to step number 1).
6. Turn the periodic transmissions back on by sending the following Maretron proprietary
NMEA0183 sentence to the SSC200 - $PMAREXE,SSC200,,FD,1,,,<CR><LF>
7. Proceed to Installation-Offset Correction
SSC200 NMEA 0183 Installation-Offset Correction
Installation-offset correction can be performed by sending a Maretron proprietary NMEA 0183
sentence to the SSC200. The procedure is as follows:
1. Make sure the vessel is laying in flat water on a known heading,
2. Send the following Maretron proprietary NMEA 0183 sentence to the SSC200:
$PMAREXE,SSC200,,24,"known heading in tenths of degrees",,,<CR><LF>
Where "known heading in tenths of degrees" is expressed in 10
would be programmed as 1217)
Sending this Maretron proprietary NMEA 0183 sentence to the SSC200 causes the heading,
roll, and pitch offsets to be written to permanent memory.
