Section 4 — Control Panels
Chop
This feature is useful for engineering checks and system alignment of gains
and phasing. In this mode the output switches rapidly between two inputs.
Note that you can select chop mode only when a single breakaway is
selected.
To enter chop mode, select valid sources in both the in use and preset
sections of the display. Then press the CHOP button.
The output remains in chop mode until any button on the panel is pressed,
or until a source is changed on the current destination by another control
panel or by an external computer.
Sleep Mode
In this mode the vacuum fluorescent display is blanked during periods of
inactivity to extend its working life. If this mode has been switched on, then
the display is automatically blanked after there has been no change on the
panel for more than one hour. The panel automatically exits the sleep mode
if any button on the panel is pressed or if another panel changes the current
destination on the panel.
Joystick or Microswitch Override
This feature is used for matching the color balance of several cameras.
Microswitches in the camera control units are pressed by the engineer
conducting the line-up to select the camera in use onto the line-up monitor.
It overrides the current selection made on a remote panel. When the
microswitch contact is released the override selection reverts to the
previous selection made on the conventional panel.
Each control panel can support up to eight cameras. The user indicates in
the software configuration which inputs of the matrix are selected by the
joystick contacts. Normally video only is selected by the joystick, but there
is no limitation placed by the system and any level may be selected.
1. Press and hold the joystick to make an override selection.
2. Release the joystick to return to the previous selection made by the
panel.
3. If two or more joystick buttons are pressed, the latest press takes
priority.
