read/write analog input and output

[satvrn5]

hello!

I have the card PCI 6221 and I have to manage 5 analog inputs and 1 analog outputs.  I have no problem reading analog inputs and writing analog outputs. however, I would like to read the analog output by routing it to an internal port. But I see an error: -50103ressource reserved.

How can it be possible to do this measure? 

Thanks.

Since this DAQ card uses multiplexing to read/write inputs/outputs make sure you use only 1 task for analog input and 1 task for analog output.

Hope this helps.
