i use NI PICIe 1429 frame grabber to acquire image by Linescan Basler SpL4096 camera under LabWindows/CVI.
The interface, session and grab function work well in free-run mode.
I need to acquire line synchronized with external trigger generated via PCI 6731 and passed to frame grabber via RTSI bus.
I have checked that the trigger signal is correctly on the RTSI bus on the frame grabber.
I configure the External trigger with the imgSessionTriggerConfigure2 or imgSessionLineTrigSource2, but i have always a timeout on the grab or snap function when try to acquire, because the camera/framegrabber don't see the trigger signal.
