Hello everyone,
i hope someone can answer our questions, on some we already think we know the answer but we want sureness on this issues, because our application is not working as intended so far.
1) We try to trigger our 1428 framegrabber with a regular TTL signal on the T0 entrance of the IMAQ D6804 cable. The grabber now sends a trigger signal to the camera, is this correct?
2) If so, which type is this trigger signal (LVDS/TTL)?
3) Why do we always get an image which is a little bit later (about 0-2 ms) as our triggerpulse on the grabber (whether we run our camera in free running, external triggered or internal triggered mode)?
4) What is the right value to change our camerafile to trigger on the grabber?
Best Regards,
Niklas
what we use:
TTL signal: 1 Hz frequency, 1 ms pulse width
camera: SVS204MFCL (by SVS-Vistek) [cameralink]
camerafile: SVS-Vistek SVS 204MFCL_0.icd (from
www.ni.com/camera/)

software: LabView 7.1, IMAQ 3.5, IMAQ Vision 7.1.0, NI Camera File Generator 2.0.1
