With the OEM boards
NI USB-6212
NI MIO USB-6423
i can easy internally read back the value on AO with the task string like:
Dev1/_ao0_vs_aognd
with the NI USB-6451 , i just get error -200170
Physical channel specified does not exist on this device.
Refer to the documentation for channels available on this device.
Unfortunately i cannot find any information about all internal channels supported by the 6451
Any idea how i can internally readback AO ?
1000Tnx in advance
