Reset Button
j Reset button — The Reset button initiates various levels of reset to the
matrix switcher. Press and hold the button while the switcher is running or
while you power up the switcher for different reset levels.
See Rear Panel Reset Operations on page 78, for details.
NOTE: The CrossPoint 450 Plus and MAV Plus 2412, 2424, 3216, and 3232 do not
have the Reset LED shown in the figure at right.
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 25 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.
