My DAQ card is NI6503,I use DAQmx write "digital waveform 1chan Nsamp.vi" in order to write digital data to device teminal,but why I can't get the result I want as depited in the picture.(accessory).
In addition, I input four samp "1001" via DAQmx write "digital waveform 1chan Nsamp", I hope to get "1001" from DAQmx read "digital waveform 1chan Nsamp.vi",but the result is "1111". It seems that the first three signal "100" has nothing to do with the result, why?
Thank you for your reply
sincerely friend
