Generating a pulse train

[sami]

Hi all,

I'm using PCI 1200 and i'm trying to generate a 2kHz signal from
the output pin of counter 1 (pin 43). What i did is just placing
a "Pulse Train" icon on the diagram window and connected the
device # and the freq. I entered 1 for the counter #. When I ran the
vi i got the following message:

" Error 10403 error occured at CTR Group Config.
The specified device does not support the requested
action "

I tried using the "Generate Pulse train (DAQ-stc).vi" and i got a similar
error. I don't think this vi works for PCI1200. I foud another one
"Generate Pulse train (8253).vi", I placed a while loop around the case
structure and it ran without errors but i couldn't
measure any freq signal from the output pin using my scope. I can pic
k up
a voltage from the output but it's constant.

Any help is appreciated.
thanks

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. Also, remember that you will not be able to use new DAQ features (e.g. DAQ Assistant, DAQmx, etc).

Hope this helps!
