Table 5—PGN 126270 Status Codes
SSHS NMEA 2000 Received PGNs
PGN 126208 – NMEA Command Group Function – Manufacturer’s Proprietary Reset
This will initiate a reset and force the SSHS to start the calibration process.
Field 1:
Complex Command Group Function Code (8 bits) – set this field’s value to 0x01,
which denotes a command PGN.
2:
Commanded PGN (24 bits) – set this field’s value to 126720, which denotes the
Manufacturer’s proprietary PGN.
3:
Priority Setting (4 bits) – set this field’s value to 0x8, which indicates to leave priority
settings unchanged.
4:
Reserved (4 bits) – set this field’s value to 0xF, which is the value for a reserved field
of this size.
5:
Number of Pairs of Commanded Parameters to Follow (8 bits) – set this field’s value
to 0x4, indicating that four parameters will follow.
6:
Number of First Commanded Parameter (8 bits) – set this field’s value to 0x1
7:
Nobeltec Vendor ID and Industry Code (16 bits) – set this field’s value to 0x9889
8:
Number of Second Commanded Parameter (8 bits) – set this field’s value to 0x02
9:
Product Code (16 bits) – set this field’s value to 0x1B2, which is the NMEA 2000
product code for the SSHS.
10:
Number of Third Commanded Parameter (8 bits) – set this field’s value to 0x03
11:
Software Code (16 bits) – set this field’s value to 0x0001, which is the identifier for
this version of the Manufacturer’s proprietary protocol.

Deviation Calibration Turning
Too Slow During calibration, the vessel must not turn too slowly
where the SSHS is unable to reliably develop deviation
data. If the SSHS senses the vessel turning to slowly, it
will issue this message and restart deviation calibration
as long as it has not failed five times.
06
Deviation
Calibration Invalid
Movement During calibration, the vessel must not jerk or reverse
directions where the SSHS is unable to reliably develop
deviation data. If the SSHS senses an invalid
movement, it will issue this message and restart
deviation calibration as long as it has not failed five
times.
