Parallel sampling - different rates

[lopez]

NAKeel,

you are very astute.  I have recently changed what the NI 9221 is docked into. I switched from a compact DAQ chassis to a USB single module port.

However, I did switch the source in my VI.

never the less, I did got back into MAX and reset the device and restarted the whole system. Lo and behold it now works.

thanks for your help very much.

I also must thank CoqRouge for suggesting a single loop and pointing out how the read operations affect timing.
