external signal to synchronize switching during the vertical interval. Without the
external sync locking feature, switching between inputs can result in a brief rolling

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2-22showsabasicexternalsyncconguration.TheExtSyncconnector

signal to be passed on to another video device, if required. Terminate the tee
connector if desired.
