raw ordering for multiple PXIe 4492 cards

[magnetsu]

Hi,

Can anyone share some insight on the ordering of the raw data for PXIe-4492 cards? For a single PXIe-4492 card, I think the raw data are interleaved. What's the format for the raw data from multiple PXIe 4492 cards acquiring data in a single DAQmx measurement task? Suppose we use two PXIe-4492 cards to acquire 16 input signals, each card acquiring 8 channels. Issuing the DAQmxReadRaw command returns the raw data in a 1D array. Does the first half of the array contains the data from the first PXIe-4492 card and the second half for the second card? 

Thanks,

XR

which API are you using?

Typically you would not need to go to raw measurements and instead use the Read 1D waveform and the waveform order corresponds to the order in which channels are added to the task or you can wire any order required to "channels to read" property and it will be used for the Read 1D waveform.
