Digital Triggering With Pretrigger Samples

[EZimney]

I am unable to trigger the PCI-6115 using the Digital Trigger A when the number of Pretrigger samples is greater then 0. Everytime I run the VI the acquisition times out. When I set the number of Pretrigger samples equal to 0 the VI works fine. I need to acquire pretrigger samples. What do I need to do to get the card to trigger properly?

EZimney,

Are you currently using the onboard memory of the PCI-6115? Currently, pretriggering is not supported in this mode. Please see the following Knowledge Base article for more information.

How Do I Use the NI 6115 and NI 6120 Onboard Memory to Store Acquisition Data for Later Retrieval?
