I have a 5413 in a PXIe-1075 chassis. I'm having a problem getting signals out the PFI 0 an PFI 1 connectors. I want to use those outputs to trigger other 5413 cards.
I get the intended signals out of Ch 0 and Ch 1 so I can communicate with the card and have no reason to think there's a hardware issue. I've verified no pulse/trigger out on the PFI connectors with an oscilloscope. A screen grab of my code is attached (sorry, can't send actual code).
See any problems with the code?
It's unclear which PFI line you configure first in the screenshot of the code. But what is happening is that the second call re-configures and overwrites the first one.
Try making the configuration call once with value "PFI0,PFI1" if you want to export the signal to both destinations, rather than overwrite the configuration by calling twice.
Hi Marcos, thanks for the reply.
Sorry about the overlap of constants in the screen shot. It was one of those things you see after you hit send.
Changing the configuration call as you suggested didn't change the performance, and actually caused an error further down the line.
I did find/learn two things:
