Hi,
Error 200077 means that the operation you are trying to perform or the values you selected are not supported on the device you are using. You might be designating options for the data acquisition that are not available on your device, such as in triggering or clock configurations. Likewise, you might be trying to configure invalid ports or self-calibration parameters.
Also, whenever you get the error -200077, LabVIEW will indicate why the error is occuring. More often than not, it is because the value that you have requested is out of range. In order to correct this error, note what the accepted value range is and change your configuration accordingly. If you need to read in values that do not fall within the range, you can scale the values by using custom scales that can be created either in MAX or in LabVIEW.
I hope this helps.
George
