How do I set the master clock output frequency on the PCI-1424?

[Jeff Rienstra]

I want to use the master clock to generate the pixel clock to the imaging chip.

Try inserting the following text immediately before the last closed bracket in your camera file and let me know how this works for you.

Oops...change the "Precision (0)" tag to "Precision (1)"

Thanks. This does exactly what I wanted.

Hi,
We have tried everything to be able to set the Master Clock Frequency (please confirm pins 89 and 90 on the 100 pin connector). Everything we try including opening NI supplied camera files sets the Master clock to 40MHz.

You're code however does do something, the Master clock frequency is set to 5MHz when we open a camera file with your code included. All the attributes show up in MaX but changing the values from Max has no effect, and the frequency remains at 5MHz. We undertake an apply and snap after each change of value with no effect.
Am I missing something as the command OnBoardClock is supposed to be used to set the Master Clock Frequency, but you don't use that in your text at all. I would appreciate an explanation of the text yo
u use, if you have the time, as I cannot find any reference to how the software knows what "Frame Grabber Clock" is.
Thank you in advance for your help.
