5. Continue turning the vessel through at least 3 circles until you see one of the following
manufacturer’s proprietary sentences:
• $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.
• $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 manufacturer’s
proprietary NMEA0183 sentence to the SSHS - $PMAREXE,SSHS,,FD,1,,,<CR><LF>
7. Proceed to Installation-Offset Correction.
SSHS NMEA 0183 Installation-Offset Correction
Installation-offset correction can be performed by sending a manufacturer’s proprietary NMEA
0183 sentence to the SSHS. The procedure is as follows:
1. Make sure the vessel is laying in flat water on a known heading.
2. Send the following manufacturer’s proprietary NMEA 0183 sentence to the SSHS:
$PMAREXE,SSHS,,24,”known heading in tenths of degrees”,,,<CR><LF>
Where “
known heading in tenths of degrees
” is expressed in 10
th
of degrees (i.e., 121.7°
would be programmed as 1217)
Sending this manufacturer’s proprietary NMEA 0183 sentence to the SSHS causes the
heading, roll, and pitch offsets to be written to permanent memory.
