How to enable triggered acquisition for NI 4472 PCI card? while defining the task which signal has to select as external trigger PCI0 or any other option as I am connecting the external signal to external trigger terminal.

Using DAQmx it's easy to specify which external trigger terminal to use in your task. If you are using LabVIEW, you can drop the DAQmx Trigger VI onto your VI and configure whether it is a start or reference ( a.k.a stop trigger) trigger, and also specify the terminal which the trigger signal is connected to, in your case it would be PFI0 (I'm assuming you meant PFI0 and not PCI0).

Let me know if you need any further clarification.
