We built a LabVIEW application, using digital inputs from a PCI-6510 card.
By the way, next to that card we have a RS-232 card from NI with 4 serial outputs in our PC.
The DIO card was installed using the automation explorer and everything worked fine.
BUT...
Sometimes after rebooting the computer, the LabVIEW application doesn't work anymore.
We looked at the automation explorer and the card seems to be registered twice in the automation explorer,
once with 'dev1' and once as 'dev2'. Using 'dev2' and the Automation Explorer shows us that the card is still OK.
But, our application using 'dev1' failed. After removing the 'dev2' instance from the Automation Explorer, everything works again...
But some reboots later, the problem araised again. The same card was registered again (as 'dev2'), while we didn't do anything (did not startup the automation explorer, neither is it stored in the startup page of windows).
How can we avoid that the same card was registered twice in the Automation Explorer??
Please help
Thanks in advance.
