Boresight Compatibility Mode
MBF<> Switch system to Fastrak Compatible mode.
MBI<> Switch system to Firmware Version 2.x Compatible
mode.
In firmware versions prior to 3.00 the B{stationNum}<>
command was implemented as the Heading Boresight (see
below) and full boresight was not available. To maintain
compatibility with the user software written at that time, two
Boresight Compatibility modes are available. In Fastrak
Compatible mode B{stationNum}<> command executes full
3-DOF boresight and MB{stationNum}<> effects heading
only. In the Firmware Version 2.x Compatible mode the
meanings of these commands are reversed.
Default Firmware Version 2.x Compatible, MBI<>
Boresight B{stationNum}<> (Fastrak compatibility mode)
MB{stationNum}<> (Firmware Version 2.x compatibility
mode)
Boresight a station. If boresight reference angles have
been specified by the G{stationNum}[yawref, pitchref,
rollref]<> command prior to issuing of Boresight command
then that orientation becomes the new reference point.
The angles output by the tracker at that orientation
become zero. Otherwise, system uses current station
orientation and that becomes the new reference line of
sight. Please make sure that the object being tracked (like
an HMD) is leveled and is pointing down the x-axis when
boresighting a station.
Unboresight b{stationNum} <> (Fastrak compatibility mode)
Mb{stationNum}<> (Firmware Version 2.x compatibility
mode)
Unboresight a station. Reference angles are cleared for
the specified station.
Heading Boresight B{stationNum}<> (Firmware Version 2.x compatibility
mode)
MB{stationNum}<> (Fastrak compatibility mode)
This command has no effect with the IS-900.
