I can not use two PCI-1407 cards together.Why?

[lincoln]

When I installed two PCI-1407 cards on the same computer, I can find one card in the M&A Explorer,and that card can work well.But another card is invisible in the M&A Explorer.I can find the card in the source manager of windows 2000.I can't find the reason.Give me a hand,please.

If either of the PCI-1407 cards is rev E or higher, then you need to have NI-IMAQ 2.5.1 or higher installed. You can find the revision by looking at the assembly number on the card, 184895x-01, where x is the revision. Otherwise, I would troubleshoot this like any other NI PCI card. Make sure you have the latest version of the NI-IMAQ driver. Try the cards in multiple slots and in multiple computers if feasible. Does each card work fine when installed by itself? Is there anything unusual about this computer (industrial PC, unusual chipset, etc)? Narrow down the problem to one particular card, slot, or computer. You can also try updatin
g to the latest win2k service pack.

Dear Sir,

Adding to the answer posted by Brent, I would really check if you have done a refresh in MAX. You can go to View >> Refresh inside MAX, or press F5. This is a very common issue so that is why I believe is worth mentioning here.
