Thanks for Your Help.
I don't have all the NI Cards which I listed but the user of my application will use it. I don't know in which slot he will put the card. I need to know the dev code for all these cards , so that in my function which does enumeration using 'Init_DA_Brds' will compare the dev code returned by it with the list of dev codes. In the Init_DA_brds function in manual does not list for all the cards. If u can tell me where I can find out the dev codes for all the NI cards will be very useful.I still need to know the dev code for PXI 5404 and PXI 5401.
once again thanks
