Troubleshooting Self Test Failures
The following topics explain common error messages generated by the Self
Test in MAX.
Application In Use
This error occurs if you are running an application that is using the
CAN card. The self test aborts to avoid adversely affecting your
application. Before running the self test, exit all applications that use
NI-DNET or NI-CAN. If you are using LabVIEW, you may need to exit
LabVIEW to unload the NI-DNET driver.
Memory Resource Conflict
This error occurs if the memory resource assigned to a CAN card conflicts
with the memory resources being used by other devices in the system.
Resource conflicts typically occur when your system contains legacy
boards that use resources not properly reserved with the Device Manager.
If a resource conflict exists, write down the memory resource that caused
the conflict and refer to the documentation for your Windows operating
system for instructions on how to use the Device Manager to reserve
memory resources for legacy boards. After the conflict has been resolved,
run the Self Test again.
Interrupt Resource Conflict
This error occurs if the interrupt resource assigned to a CAN card conflicts
with the interrupt resources being used by other devices in the system.
Resource conflicts typically occur when your system contains legacy
boards that use resources not properly reserved with the Device Manager.
If a resource conflict exists, write down the interrupt resource that caused
the conflict and refer to the documentation for your Windows operating
system for instructions on how to use the Device Manager to reserve
interrupt resources for legacy boards. After the conflict has been resolved,
run the Self Test again.
NI-CAN Software Problem Encountered
This error occurs if the Self Test detects that it is unable to communicate
correctly with the CAN hardware using the installed NI-CAN or NI-DNET
software. If you get this error, shut down your computer, restart it, and run
the Self Test again.
