Hi Sami, The PCI-1200 Legacy DAQ Board is not supported by new versions of NI-DAQ. If you have a newer version, I would go uninstall DAQ and reinstall DAQ version 6.9.3, which can be found <a href="http://www.ni.com/support/daq/versions.htm">here.</a> Also, remember that you will not be able to use new DAQ features (e.g. DAQ Assistant, DAQmx, etc).
I found an example program <a href="http://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=B45EACE3DD3556A4E034080020E74861&p_node=DZ52328&p_source=External">here</a> that may help you. I'm not sure if you've tried this one. Hope this helps! Jeremy L. National Instruments
