Hi

You can use the PFI lines as trigger to the hardware. It means that you can setup your board to wait for the trigger signal on the PFI line. The board will wait for the trigger. The trigger will not activate the vi (sotware), but will start A/D conversion of the PCI-6024 (the hardware).

You can take a look on the example "Continuous Acquisition & Graph (Buffered) Using Digital Triggering" and then go to the function AISTART. This vi is calling the function Trigger Config. Take a look on the help description on this function. It explains how to setup a digital trigger by the PFI lines.

Hello,

By the way here are the places to find the trigger related examples.

LabVIEW Help>> Find Examples>> Hardware Input and Output>>DAQ >> Analog Input.

Please do let me know if you have any questions.
