PXI 6602 shared DIO Counter lines

Hi,

 

I have a question regarding the PXI-6602. From the manual I see that some of its PFI channels are shared. If I wanted to use a counter to generate a timed pulse. Can I use the associated gate and source PFI as digital output lines without affecting the counter?

 

Here's a concrete example: Let's say I'm using the counter 7 to generate a timed pulse on PFI 8 which is the CTR OUT. Can I simultaneously use PFI 10, which is listed in the manual as having possible signals CTR 7 Gate and P0.10, as a digital output? Can I simultaneously use PFI 11, which is listed in the manual as having possible signals CTR 7 Source and P0.11, as a digital output?

 

Thank you!

Hi,

 

Here is a good KB that explains how to work with PFI lines on the 660x boards :

Thank you Luis for this kb. It will be useful.

However, I am still not sure if I can associate the gate and source PFI as digital output lines without affecting the counter. i.e. use the gate and source PFI of the counter as digital output and still use the counter out for the counter at the same time.

 

Thanks

Hi,

 

Take a look at this example related to routing counter signals through the RTSI lines.
