GNS >From your program, all you need to do is add a control that will allow you so specify the time you want to acquire data. Then multiply this value by the 'Scan Rate' which is currently at 40000. This will give you the total number of samples to acquire. (You will also need to multiply by the number of channels if you are acquiring from more than one) Then send this value to the 'Buffer Size' node on 'AI Config'.
Let me know if you have further questions. Brian
