HSDIO PXI-6552 TClk with Onboard Clock

[engwei]

Hi,

When I use TClk VIs, the acquisition clock cannot be configured as OnboardClock. A error message will be prompt out. 

Then I insert this, and the error message will not prompt out anymore. 

Why the error can be occur ? I place the vi (PXI 10 line) to eliminate the error. Should I do this ? Any suggestion there ? Thanks for your time.
