https://ni.lithium.com/t5/LabVIEW/Generating-a-pulse-train/m-p/123544#M74331 Hi all,<BR /><BR />I'm using PCI 1200 and i'm trying to generate a 2kHz signal from<BR />the output pin of counter 1 (pin 43). What i did is just placing <BR />a "Pulse Train" icon on the diagram window and connected the <BR />device # and the freq. I entered 1 for the counter #. When I ran the<BR />vi i got the following message:<BR /><BR /> " Error 10403 error occured at CTR Group Config.<BR /> The specified device does not support the requested<BR /> action "<BR /><BR />I tried using the "Generate Pulse train (DAQ-stc).vi" and i got a similar<BR />error. I don't think this vi works for PCI1200. I foud another one<BR /> "Generate Pulse train (8253).vi", I placed a while loop around the case<BR />structure and it ran without errors but i couldn't<BR />measure any freq signal from the output pin using my scope. I can pic<BR />k up<BR />a voltage from the output but it's constant.<BR /><BR />Any help is appreciated.<BR />thanks <BR /> Fri, 12 Mar 2004 20:14:05 GMT sami 2004-03-12T20:14:05Z https://ni.lithium.com/t5/LabVIEW/Generating-a-pulse-train/m-p/123544#M74331 Hi all,<BR /><BR />I'm using PCI 1200 and i'm trying to generate a 2kHz signal from<BR />the output pin of counter 1 (pin 43).

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).<BR /><BR />I found an example program <A href="http://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=B45EACE3DD3556A4E034080020E74861&amp;p_node=DZ52328&amp;p_source=External">here</A> that may help you. I'm not sure if you've tried this one.<BR /><BR />Hope this helps!<BR /><BR />Jeremy L.<BR />National Instruments <BR /> Tue, 16 Mar 2004 15:30:15 GMT https://ni.lithium.com/t5/LabVIEW/Generating-a-pulse-train/m-p/123545#M74332 Jeremy_L 2004-03-16T15:30:15Z
