Troubleshooting and
Common Questions
This appendix describes how to troubleshoot problems and answers some
common questions.
Missing Board in the NI-CAN Configuration Utility
The NI-CAN Configuration utility contains configuration information for
all of the CAN hardware it is aware of that is installed in your system. To
start the NI-CAN Configuration utility, double-click on the NI-CAN
Configuration icon in the Control Panel:
• Windows NT 3.51–Open the Control Panel in the Main group of
the Program Manager.
• Windows NT 4.0 or later–Select Start»Settings»Control Panel.
If your board is not listed under NI-CAN Configuration, the board is not
properly installed. For the PXI-8461 or PXI-8460, this means that the board
is not physically present in the system. If your board is firmly plugged into
its slot and the problem persists, contact National Instruments.
Diagnostic Utility Failures
The following sections explain common error messages generated by the
NI-CAN Diagnostic utility.
Resource Errors
This error occurs if the memory resource or interrupt resource assigned to
a board conflicts with the resources being used by other hardware in the
system. If a resource error occurs, click on the Resources button in the
NI-CAN Configuration utility to view the board resources. For the
PXI-8461 or PXI-8460, if legacy hardware in your system is using the
resources, change the resource configuration of the legacy hardware. If you
need help, refer to the documentation that came with your hardware. If the
problem persists, contact National Instruments.
