How does a line scan camera trigger Frame grabber (1433)?

Hello everyone!

I have a line scan camera (e2v OCTOPLUS) and I linked the camera to 1433 through camera link. I want to know How does a line scan camera trigger Frame grabber (1433)? Does the camera use the signal of HSYNC?

Or, the camera doesn't trigger 1433. And in this situation, how does 1433 know when to acquire the line from the line scan camera?

I want to use the function,imgSessionTriggerDrive2(),to output signals representing the trigger or clock, according to which 1433 acquire a line from the line scan camera.

Thanks!
