j
Reset button — The Reset button initiates four
levels of reset on the matrix switcher. Use an
Extron Tweeker or a pen to press and hold the
button while the switcher is running or while you
power up the switcher for different reset levels.
See "Performing soft system resets (reset modes 3, 4, and 5)" in chapter 3,
"Operation", for details.
• Events (mode 3) reset — Hold Reset for 3 seconds, then release and press it again
to toggle events monitoring on and off.
• IP settings (mode 4) reset — Hold Reset for 6 seconds, then release and press it
again to reset the switcher’s IP functions.
N IP settings reset does not replace any user-installed firmware.
• Absolute (mode 5) reset — Hold Reset for 9 seconds, then release and press it
again to restore the switcher to the default factory settings.
• Hard reset — Hold Reset while powering up the switcher to restore the switcher
to the default base firmware, user settings, and files.
N Hard reset does not clear the current configuration.
External sync (systems with MAV Plus video BMEs)
The MAV Plus video switcher BME 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
connector on BNC 0 for genlocking the video signal in broadcast or other
sync-critical applications.
N In systems with multiple low resolution video BMEs (such as component video
and S-video systems), only the External Sync connector on the luminance (Y)
video plane’s BME needs to be connected to the black burst generator. This BME
should be BME 0.
Figure 2-12, on the next page, shows a basic external sync configuration.
The Ext Sync connector receives the timing signal. A tee connector on the
BNC allows the signal to be passed on to another video device, if required.
Terminate the tee connector if desired.
If no external sync timing source is connected to the switcher, switching
occurs immediately.
