Troubleshooting
If you have any problem with the operation of the Digidata 1322A, follow this
section to check out some possible problems and solutions. If your problem is still
not resolved,
please go through the "Before You Call" checklist below prior to
contacting us
.
1. If you suspect that the Digidata is not working properly, isolate the problem!
Disconnect any external instruments and test the Digidata by itself. If you
suspect problems with the analog or digital outputs, use a voltmeter or
oscilloscope to monitor the signal. If you suspect a problem with the analog or
digital inputs, hook up a known signal source such as a signal generator, or even
the analog output if you know it is working properly.
2.
The Power light on the front panel is off.
Check the fuse. The fuse box is found in the middle of the Power Unit on the
rear panel. Simply remove the power cord and then reach underneath the fuse
box to open.
3.
The screen shows a straight line instead of the input signal.
Are all external connections properly made? Check cables for continuity
problems. Make sure the SCSI cable is securely attached to both the card and
the interface box. Try rebooting the computer and restarting the Digidata.
4.
Noise is introduced when the data is digitized.
If noise is added to the signal on the analog input, make sure that all cables are
routed away from switching power supplies, power cords, monitors, or any other
major sources of noise. Check for proper ground connections. See below for
more information on proper grounding practices.
5.
The Ready light on the front panel flashes continually during operation.
The Digidata 1322A is in a problem state. Call Technical Support at Axon
Instruments for a Return Merchandise Authorization (RMA) number before
returning the unit for repairs.
