Do the triggering signals for the DALSA CL-P1 4096 camera work properly?

Question

(Since I wasn't sure if anyone had seen my additions to the question "How do the DALSA CL-P1 4096 attributes correspond to the i/o trigger signals?" 6/3/2002, this is an addition to that question.)
We are using a DALSA CL-P1 4096 camera with the NI IMAQ PCI-1422 image acquisition board, and we believe the signals are not triggering properly on the "Controlled" integration setting. All images are coming out black, but all signals are present. What we, as well as DALSA's support believe the problem is is that the PRIN signal goes low before LVAL goes high. Attached are the timing diagrams that we are getting and which we should be getting (provided by DALSA support). We would like to
know if there is anything you can do for us if this is actually a problem with how the board is triggering the control signals (i.e. if there is a patch you can provide us, or a way to program how the board triggers the signal). Thanks for all your help.

Answer 1

I was wondering why I hadn't heard from you and when I looked at your previous question I saw that my last post didn't make it to the page. But I see what you mean from the timing diagrams that you attached and we should be able to extend the length of time that the PRIN is high so that it doesn't go low until after the LVAL goes high. However, to do this it means changing the camera file (.icd) for that camera and that would probably be best while talking on the phone if possible so that we make sure that it all works correctly. Just go to www.ni.com/ask and generate a phone support request and it will give you a toll-free number to call. I'll be on the lookout for your call.
