USB-6210: Differential input pairings - error

[traindoor]

Hello,

I have been having a problem reading differential inputs. For my particular DAQ model USB-6210, the differential inputs are AI0:AI8, AI1:AI9, etc. I have been unable to use those to inputs for my block diagram as I keep getting the Error -200077 (Requested value is not a supported value for this property.... - this error is for AI8, 9, etc, i.e. the other end of the differential input pairing). Please find the attached VI. The RSE readings work fine. 

Thank you!

Once a channel is configured as Diff, you can not aceess the other input. DAQ knows which pair of cahnnels get paired together.

Just change the I/O spec to daq/Ai0-3 and adjust your indexing into the array.
