Issue Details

I am running an output task in NI Measurement & Automation Explorer (MAX). When the Generation Mode is set to anything other than 1 Sample (On Demand), I receive the following error. Why is this occurring?

Error -200077 occurred at DAQ Assistant

Possible Reason(s):

Requested value is not a supported value for this property. The property value may be invalid because it conflicts with another property.

Property: SampTimingType
Requested Value: Sample Clock
Possible Values: On Demand



This error occurs when the MAX task attempts to use an onboard clock with hardware that does not support a Sample Clock. Use 1 Sample (On Demand) as the Generation Mode to prevent this error.
