Hello;

You don't need to configure the DAQ device to perform DMA data transters. It's set as DMA by default.

The error you are getting can tell you more about the problem itself. I'm wondering if the problem is on the FIFO overflow which is caused by overhead in the while loop where the AI Read.vi is in. If that is the case, you will need to optimize the code inside the loop so you can retrieve data faster from the on board FIFO.

Hope this helps.
