4. To enable transmission of the HDM sentence at intervals of 1000 ms:
• $PMARSETPX,SSHS,,01,1000

9. To disable transmission of the PMAROUT sentence:
• $PMARSETPX,SSHS,,04,0
10. To enable transmission of the PMAROUT sentence at intervals of 1 sec:

SSHS NMEA 0183 Initiated Deviation Calibration
NMEA 0183 initiated deviation calibration is accomplished by turning the vessel through at
least 3 complete circles after the SSHS receives a manufacturer’s proprietary NMEA 0183
sentence.
The procedure is as follows:
1. Ensure that the compass has been properly installed per
Installation

.
2. Warm up the compass by operating it approximately 10 minutes.
3. Turn the vessel (either direction) such that you complete a full 360° turn in 2½ minutes
or less (try not to go below 1 minute for a complete circle),
4. Send the following manufacturer’s proprietary NMEA0183 sentence to the SSHS while
continuing to turn the vessel:
• $PMAREXE,SSHS,,FD,0,,,<CR><LF> This will turn off all periodic transmissions
such that you can easily see status messages associated with the calibration
process
• $PMAREXE,SSHS,,F0,,,,<CR><LF> This will initiate a reset and force the SSHS
to start the calibration process.
