Hi Everybody,
My problem is using the CWDIO components to control NI USB-6525.
Information:
OS: Windows 7
Programming Language: C# & VB
Question:
I add the components CWDIO, but it always throw out "run time error 68: Invaild device" when I execute this "CWDIO1.SignalWrite 0"
But if I use the NI PCI-6503 with same command , it works properly well.
1. Is this components able to control the the USB-6525?
2. Why there is no error message throw out when there is no DIO card connected using this component?

USB 6525 has no digital out lines, only digital in. Therefore you get runtime error as soon as you call SignalWrite (meaning OUT).
