i have a question about connecting a digital port (e.g. PFI2) to RTSI port (e.g. RTSI3).
My device: PCI6731
i have already sucessfully connected 'Ctr0InternalOutput' to RTSI0.
Now I need a digital input to another RTSI. But I failed to do that and got the prompt message: 'Specified route cannot be satisfied, because it requires resources that are currently in use by another route.'
Please tell me how to connect a digital input to a RTSI?
Thank you!

Greetings lyonco.
This is a great question and can be somewhat of a tricky task at times. For advice on how best to proceed, please refer to the following KnowledgeBase article.
Why Do I Get Error 89137 "Specified route cannot be satisfied..." When Routing PFI Lines Over RTSI?
In the case of the PCI-6731, it appears from the routing table that Counter0 is used as a subsystem when routing from any of the PFI lines to RTSI0-6. I hope this information helps get you on the right track.

Thank you very much Michael G!
From your answer I understand now that PFI cannot be usd if I have already used Counter0. I read the link you provided. It seems like I can use the reserved port of PCI6731. I am not sure if it possible or any other port I can use to connect to RTSI.
Thanks again!
