hi ,i am using pci 6014 DAQ card for my project.
now i am trying to take optocoupler o/p on dio line of DAQ card.
but the problem is when i checked the optocoupler module seperately it works fine .when i connect it to the dio pin of DAQ card the voltage ot dio pins droup to 0.7v and remains constant even if o/p of optocoupler is chaged. why is it so?
is it problem if impedance matching?
if yes tell me solution plz
