Issue Details

I am using a DAQmx Device with model number 61xx, 62xx or 63xx, which is multiplexed. The AI sampling clock initiates the AI convert clock on which the individual channel samples are measured.


Can I change the channel order? For example, I want to measure channels ai0 to ai3 in the order 3, 1, 0, 2.

Solution

You may change the order of channels that are scanned by changing the order in the physical channels parameter of the analog input virtual channel.

In LabVIEW the above example of channel order would look like this:

Additional Information

C Series multiplexed analog input modules 92xx do not allow changing the order of channels.
