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 Operations" in chapter 3, "Operation", for details.
N 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 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.
