i need help here

i have a 6009 USB

and at MAX it is called DEV 1

and in the program is appearing this error =x

give me some feedback please!

So you want to acquire data at your DEV1, but in LabVIEW you selected a Dev2.

Either you change the alias of your USB6008 in MAX to Dev2 or you select DEV1 in LabVIEW.

ok the first problem is solved...

but now in the another program

its appearing:

Error 1 occurred at Read File+ (string): Read File
 

Possible reason(s):

LabVIEW:  An input parameter is invalid. For example if the input is a path, the path might contain a character not allowed by the OS such as ? or @.

NI-488:  Command requires GPIB Controller to be Controller in Charge.

Obviously, it has nothing to do with NI-488 so check the path that you are providing.
