I am using a PCIe 1427 frame grabber to capture images from a linear CCD camera.
In the MEA, I can the synchromization to "Free Run" and the "signal levels" panel as that in the below figure. The card has a 15 pin D-SUB connector and I connected a signal cable to the pin 1 and 9 in order to reach the External Trigger 0. However, I did not see the trigger TTL signal output.

You must use IMAQ trigger route to route trigger from one line to another.

Hi, Kate,
Thanks a lot!
I am wondering if it is possible to set the trigger from the frame grabber in the IMAQ.
Do you have an example for that?

Hello Ling_Wang,
Where is your trigger signal coming from?
Is it an external trigger signal.
If yes, then you should be able to use the following method:

If your trigger signal is coming from somewhere else, then please explain a bit more in detail how your complete system looks like.

Hi, Thierry
Thanks a lot! Yes, I understand to trigger the camera using an external source.
however, I prefer to use the inner trigger from the frame grabber (or the camera), so that I can set the camera to run with the highest speed.
