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

I found an example program here that may help you. I'm not sure if you've tried this one.

Hope this helps!
