5.2 Video Input/Output panel
This panel allows input selection, control of the deglitcher and
freeze functions, and timing delay.
Input Select: use the pulldown list to select between the
copper input (BNC) and the fiber optic input (if available)
• The list will only be active if an Optic Fiber module is
installed in the rear panel. Otherwise it will be grey and
locked as BNC
5.2.1 Fiber Input/Output tab
This tab will only appear when a fiber optic module is
installed in the rear panel. The panel will be appropriate to
the type of module installed.
• The “Detected” data box shows the type of module that
the AMX-3981 has identified.
• The controls that appear allow the inputs and outputs
on the fiber module to be configured.
Options: OFF or ON
5.2.2 Deglitcher tab
When the Deglitcher is active, the card supports a
hot-switch between two signals without producing a
freeze on the frame buffer, and without producing
artifacts on the output.
• In order to enable the deglitcher, the URS
signal must be selected as the reference in
the Reference panel (see section 5.11)
Deglitcher: select OFF or ON from the pulldown
