PFI used as a Digital Input PXI 6355

[JCIV]

I have something  I cant seem to find the answer to and its probably simple to someone.

I have a PXI system with a 6355 card. I need to use 4 of the PFI lines as digital inputs on port 2. I get an error when I try to start the task using port 1 or port 2. Port 0 works fine. Port 0 , Port 1 and Port 2 work fine in MAX. Something simple I am missing for sure. Thanks in advance for an help!

PXI-6355 only supports sample clock timing on Port 0. You can only use On Demand timing on the remaining ports.
