Alignment Offset
If GNSS Compass is installed into the vehicle with the positive X axis pointing forwards and the positive Z axis
pointing down, then no alignment offset is required and the roll, pitch and heading offset values can remain at
the factory defaults of zero.
If the unit is installed in a different orientation then the roll, pitch and heading offset must be entered. For
example if the unit is installed on its side with the X axis pointing up and the Z axis pointing forwards and no
change to the Y axis, then this would result in a pitch offset of +90 degrees with roll and heading remaining zero.
If there is a small misalignment due to mechanical mounting error this can be compensated for by setting the
vehicle stationary on a level surface and pressing the Zero Current Orientation button.
Note : This will only correct for roll and pitch offsets, the Heading offset must be entered manually and
saved before using this function.
All the other offsets will be measured in the realigned body co-ordinate frame (X positive forward, Z positive
down) after being corrected for any alignment offset entered.
8.2.7.3 Port Mode and Baud Rates
When changing baud rates, some Microsoft Windows machines are unable to function at the higher baud rates.
It is recommended to test the baud rate first without selecting the Permanent box. This way, if it is not possible
to communicate at the higher baud rate, a power cycle can be used to revert to the previous baud rate.
The factory default baud rate value for these ports is 115200 bps.
