External sync (MAV Plus video models)
The MAV Plus switcher switches between inputs during the vertical interval
period, resulting in glitch-free video switching. The MAV switcher can use an
external signal to synchronize switching during the vertical interval. Without the
external sync locking feature, switching between inputs can result in a brief rolling
(sync loss) or a brief change in the picture size.
k
Ext(ernal) Sync connector — Connect an external sync signal to this BNC
connection for genlocking the video signal in broadcast or other sync-critical
applications.

Figure 2-23 shows a basic external sync configuration. The Ext Sync connector
receives the timing signal. A tee connector on the connector allows the
signal to be passed on to another video device, if required. Terminate the tee
connector if desired.
