laserBIRD 2
- Troubleshooting Guide
 |
| No audible sound when Scanner
plugged in |
No Power.
System in SLEEP mode.
System in REST.
|
Check AC connections to
power supply. Check that
d-sub connector is fully
seated. Reset hardware by
cycling AC power.
Check BIRD STATUS for SLEEP
mode; issue RUN command.
Run the laserBIRD utility
and check for status of
the 'reset on CTS' setting.
If enabled and you are running
Windows, either disable
it or ensure that your application
takes control of the COM
port.
|
| Utility doesn't run |
No serial communication.
Software installation unsuccessful.
|
Check the suggestions outlined
in 'Not able to communicate'
below.
Re-initialize the HOST
PC and run the installation
again.
|
| Power-up defaults did not
change after configuring with
the utility |
Configuration
download interrupted.
laserBIRD did not reset (restart)
after burning the Flash settings. |
Restart the
laserBIRD and the utility
and set the defaults again.
Be sure to click APPLY to
send the settings to the Scanner.
Cycle Power to the laserBIRD,
and re-check the settings. |
| Not able to communicate with
the system |
Baud rate
incorrect.
COM port incorrect.
RS232 cable disconnected. |
Default Baud
rate for the laserBIRD is
38,400. Start the laserBIRD
utility using this setting,
and configure the default
for your needs. See Chapter
3 of user's manual for details.
Specify to your HOST PC the
COM port that the tracker
is connected to.
Check that the serial connections
at both ends of the cable
are fully seated. |
| Can communicate with the system,
but data not changing |
Detectors
occluded.
Detectors saturated.
Sensor connection faulty.
|
Use the utility
to check for valid data from
each detector.
Sensor may be too close to
the scanner; increase distance.
Also check for the presence
of high intensity light sources
in the operating region.
Check that sensor connector
is correctly installed and
locked. Inspect coaxial pins
for wear or damage. |
| Data is too noisy (jittery) |
Filters OFF.
DC Filter not optimized.
Reflective surfaces in the
operating region.
Interference from another
laserBIRD.
|
Check FILTER
STATUS for present state of
filter configuration. Enable
AVG and Adaptive filters as
necessary.
Check settings of VM and
Alpha_Min. Adjust until data
acceptable. See command reference
in Chapter 4 for details.
Remove object or surface
causing reflection, or adjust
Scanner mounting to minimize
effect.
If running dual scanners,
check the configuration of
the 'laserBIRD ID' setting.
Configure as detailed in the DUAL SCANNER OPERATION section in Chapter
3 of user's manual.
If configured correctly,
adjust Scanner mounting such
that the 'Performance Motion
Boxes' do not overlap. See DUAL SCANNER OPERATION in Chapter 3 of user's manual. |
laserBIRD
also contains a built-in troubleshooting
utility.
It provides a fast
and easy way to evaluate how each
of the three detectors in your sensor
is performing throughout the operating
region.
For example, if you
were experiencing interruptions
(static or noisy data) during your
tracking application, you can run
the utility and determine which
of the detectors is returning invalid
data. An occluded detector or a
saturated detector most often causes
invalid data. The utility refers
to the three detectors as Sensor
1, Sensor 2, and Sensor 3. Note
that to compute a correct measurement,
laserBIRD must receive valid data
from all three detectors in the
sensor triad.
See your User’s Manual
for further information on using
this utility.
