i would like to configure Physical channel in the fillowing Vi. when i set 0 as physical channel input i get error 200170(physical channel specified does not exist on thi device. I am using board AT-MIO-16XE-50 for signal generation. if i use other conventional DAQ Ao config, there i can set channel 0 as input. why not here? please explain? i attached my VI. thanks

The AT-MIO-16XE-50 is not supported with DAQmx. (The PCI version of the card is, but not the AT version.) The AT card is supported with Traditional DAQ however. This is why you got the error using the DAQmx VIs but not with the traditional daq VIs.
