$PMAREXE,SSHS,,F0,,,,<CR><LF>
This command causes the SSHS to be reset and is useful for initiating deviation calibration.
$PMAREXE,SSHS,,FD,0,,,<CR><LF>
This command causes the SSHS to stop outputting normal periodic data (like heading) and is
useful for observing non-periodic sentences such as status sentences during deviation
calibration.
$PMAREXE,SSHS,,FD,1,,,<CR><LF>
This command causes the SSHS to once again output periodic data. Normally, periodic data is
disabled during the calibration process such that status messages are easy to see and not lost
within normal periodic data. This sentence is used to turn the periodic data back on.
$PMAREXE,SSHS,,24,”known heading in tenths of degrees”,,,<CR><LF>
This is the command used to perform installation-offset where the compass is aligned to a
known heading and the pitch and roll are zeroed to the vessel’s current attitude. If the current
or known heading is 177.0°, then a value of 1770 should be programmed.
$PMAREXE,SSHS,,5D,0,”variation”,,<CR><LF>
This command causes the SSHS to use a manual entry for variation (variation is programmed
using 1/10 of a degree resolution – as an example use 2.3 in the
“variation”
field for a 2.3°
variation.
$PMAREXE,SSHS,,5D,1,,,<CR><LF>
This command causes the SSHS to use variation data from the NMEA 2000 interface and
ignore all other variation sources (i.e., NMEA 0183 interface and manual entries).
$PMAREXE,SSHS,,5D,2,,,<CR><LF>
This command causes the SSHS to use variation data from the NMEA 0183 interface and
ignore all other variation sources (i.e., NMEA 2000 interface and manual entries).
$PMAREXE,SSHS,,5D,3,,,<CR><LF>
This command causes the SSHS to use resort back to the factory default where variation data
is used from either the NMEA 0183 interface or the NMEA 2000 interface.
$PMAREXE,SSHS,,5E,2,”damping period”,,<CR><LF>
This command causes the SSHS to use a rate of turn damping rate corresponding to the value
programmed in
“damping period”
. The damping period is programmable from 100 to 60000,
which represents 100ms to 60 seconds.
