$PAMTC,COMP,VERIFY
Summary
Verify the user compass calibration mode.
Syntax
$PAMTC,COMP,VERIFY*hh
The verify user calibration sequence for the LB150 is as follows:
1. The weather station is installed on the vehicle. The unit under test is powered
up. User calibration has been completed successfully.
2. The $PAMTC,COMP,VERIFY*hh command is sent to the
weather station’s NMEA 0183 input channel to initiate user calibration mode.
3. During the verify user calibration process, the vehicle is rotated slowly (driven
in a circle) and the sensor calculates the resulting score. Once the weather
station has determined that enough data has been collected, it transmits the
following sentence: $PAMTR,COMP,SCORE,XXX*hh
Reply
The weather station will reply immediately with:
$PAMTR,COMP,INPROGRESS,
<1>,<2>,<3>,<4>,<5>,<6>,<7>,<8>,<9>*hh
Where fields <1> through <9> contain the data from the weather station’s
nonvolatile EEPROM, as defined in the “Q”, Query Command.
Upon successful completion the weather station will reply with:
$PAMTR,COMP,SCORE,XXX*hh
Where XXX is a score from 0 – 255, meaning TBD.
Or, upon failure it will reply with:
$PAMTR,COMP,FAILx,
<1>,<2>,<3>,<4>,<5>,<6>,<7>,<8>,<9>*hh
Where x indicates the type of failure, 1 = Timeout, 2 = Tilt Error, or 3 = Other
Error.
