ExSync Line Synchronization with Electronic Shutter Control is the fourth mode (Figure 3.4.5).
It gives the user asynchronous hardware control both start and end of integration.
The control lines ExSync and ElectronicShutter are CameraLink
TM
lines CC1 and CC2 respectively
as described in Reference A, and must be asserted by the frame grabber.
