pxi-6259 digital waveform trigger

Hi,

I need to be able to trigger the start of digital waveform acquisition or generation. And I use AI Sample Clock or AO Sample Clock as the
source of DI/DO Sample Clock.Could you please provide me more info of how to initiate pulses on AI Sample Clock (and therefore on DI Sample Clock)?

 

I use the founction DAQmxCfgDigEdgeStartTrig() in CVI to configuer the trigger, but there is an error:-200452.

 

Please provide me general idea of how to  resolve such thing in the LabWindows/CVI.

Thanks.
