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 CameraLinkTM lines CC1 and CC2 respectively as described in Reference A, and must be asserted by the frame grabber.
