External Sync Connections (HDXP 3232 only)

d
External sync connectors for bi-level and tri-level — Connect an external
sync signal to this BNC connector to genlock the video signal in broadcast or other
sync-critical applications.
The HDXP switchers switch between inputs during the vertical interval period,
resulting in glitch-free video switching when the input devices are also using the same
sync timing. The HDXP can use an external signal to synchronize switching during the
vertical interval. Without this external sync locking feature, switching between inputs
could result in a brief rolling (sync loss) or a brief change in the picture size.
Figure 5 shows a basic external sync configuration. The Bi-level or Tri-level sync
connector receives the timing signal. A T connector attached to the cable allows the
signal to be passed on to another video device, if required. Terminate the T connector
if desired.
