Hi,

I'm trying to run two U3s from 1 LabView program and it can only see one of them at a time. When using the ListAll() function, I can see the serial numbers from both, but I keep getting error# 1007 for 1 of them when I both are connected. I have a third U3 that I tried in place on the one that wasn't connecting and I get the same problem. Any ideas? This was using the example, "Multiple U3 with Multiple AIN.vi."

Thanks, Rob

I tested that example and it

I tested that example and it was working properly with UD driver 3.50. Only one process can use a U3 at a time. Make sure all applications that can use your U3s are closed, such as LJControlPanel and the examples. Then open the "Multiple U3 with Multiple AIN.vi" example and see if can use both U3s.

If you are still having issues:

Make sure you are running the latest Windows software:

Close all other applications using a U3 and check if our LJControlPanel has issues with finding and using both U3s.

Hi,

I installed the latest software and that seems to have solved the problem. The program is connecting to both of them now.

Thanks,

Rob
