Issue Details

When trying to create a stimulus/response application using NI-HSDIO, I receive an error:

Error -1074118636 occurred at niHSDIO Initiate.vi
Possible reason(s): 
Driver Status: (Hex 0xBFFA4014) Resource requested by this session has already been reserved by a different session.
Property: SupportedDataStates
Reserved Value: Disabled
Requested Value: Stimulus and expected response
Status Code: -200022


What could be causing this error?

Solution

This error is occurring because the Supported Data States property was not being set in both the acquisition and generation setting.  This property must be set in both sessions to properly configure the device for a stimulus/response application.
