BIRD STATUS
When PARAMETERnumber = 0 during EXAMINE, The Bird returns a status word to tell the user in
what mode the unit is operating. The bit assignments for the two byte response are:
B15 1 if Bird is a Master Bird -Only setting possible for laserBIRD
0 - Not used with laserBIRD
B14 1 if Bird has been initialized
0 if Bird has not been initialized
B13 1 if errors exist in the SYSTEM ERROR register (error(s) detected)
0 if no errors exist in the register (no errors detected)
B12 1 if Bird is RUNNING
0 if Bird is not RUNNING
B6-B11 Not used by laserBIRD
B5 1 if The Bird is in SLEEP mode. (Opposite of B12)
0 if The Bird is in RUN mode
B4, B3, B2, B1
0001 if POSITION outputs selected
0010 if ANGLE outputs selected
0011 if MATRIX outputs selected
0100 if POSITION/ANGLE outputs selected
0101 if POSITION/MATRIX outputs selected
0110 factory use only
0111 if QUATERNION outputs selected
1000 if POSITION/QUATERNION outputs selected
B0 0 if POINT mode selected
1 if STREAM mode selected
(Note: in STREAM mode you can not examine status)
SOFTWARE REVISION NUMBER
When PARAMETERnumber = 1 during EXAMINE, The Bird returns the two byte revision number
of the software located in The Bird's PROM memory. The revision number in base 10 is expressed
as INT.FRA where INT is the integer part of the revision number and FRA is the fractional part.
For example, if the revision number is 2.13 then INT = 2 and FRA = 13. The value of the most
significant byte returned is FRA. The value of the least significant byte returned is INT. Thus, in
the above example the value returned in the most significant byte would have been 0D Hex and
the value of the least significant byte would have been 02 Hex. If the revision number were 3.1
then the bytes would be 01 and 03 Hex.
