Figure 2-7 — Simple external sync connection example
Figure 2-8 shows another configuration, in which the timing source passes through
three video cameras and a video scan converter before connecting to the switcher.
This type of video camera is capable of synchronizing with the external timing
source for video editing applications.
If no external sync timing source is connected to the switcher, switching occurs
immediately after a front panel, RS-232, IR, or contact closure switch command.
