USB 6251 Compatibility

[older versions of driver]

Hello...

I hope some one can help me out here. I have a USB 6251 DAQ device, LABVIEW 8.5, DAQ driver 8.6.1 and running on Windows XP.

I have configured USB 6251: I am able to see it on MAX and also the test panels work well.

I also wrote a simple VI using DAQ assistant to acquire Analog inputs on channels 0 and 1 and it works just fine.

But when I ran the VI was initially programmed for PCI 6024 E, the Labview gives me error: 10401.

I don't have any other device other than the USB 6251 attached to my computer. On MAX USB 6251 is configured as Dev1 and also the VI that I am running also calls for Dev 1.

The VI written for PCI 6024 E uses traditional VI: AI Config, AI Start etc...  So my question is whether USB 6251 will work when I run traditional VI's? or am I missing something here.

Pls help me out.

Thanks

Krithika

No, you cannot run a program that uses the traditional DAQ functions with the 6251 hardware. The 6251 is only compatible with the current driver - DAQmx.

Thanks for the quick response!!

I am using the DAQMX driver 8.6.1. Its just the VI code that I am running has VI's like:  AI config, AI Read etc... The VI's are not DAQmx VI's.

So from what you are saying I need to use only DAQmx VI's?

Pls do let me know.

Thanks

I understand what you are using now and what the old program is using. My answer is still the same. You cannot use the old daq functions with your new board. You have to rewrite the old program.

Hi Krithika,

Here is a tutorial which may help you as you upgrade your code from traditional DAQ to DAQmx.

If you wanted to rewrite your program or look at examples, there are some in the Example Finder which can be accessed through the Help menu. The DAQmx examples can be found browsing by task under Hardware Input and Output » DAQmx.
