Thank you for your reply!
So I tried to read the data and then perform the calculation in the LabVIEW program, the problem was that my math calculation is using data from two groups (A and B), but the LabVIEW seems can only read from one group once everything is setup. I have to re-configure in order to read data from the other group, this will reduce the data acquisition speed due to time spent to re-configure the group.
So could you help me to have the LabVIEW code read two groups at the same time? Thank you so much!
