DEF — RE−DEFINE INPUT OVERRIDES
The control panel overrides permit a quick selection of switcher inputs and level selections. The overrides must first be
defined on the Override Set table (Figure 5−78). For each definition, there is a choice of allowing or not allowing the override
to be edited from the front panel.
Important: Front−panel editing of overrides is temporary. Download or loss of power to the SC−3000 Serial Con-
trol Interface will cause the overrides to revert to the definitions in the Override Set table.
The operator edits the override by first selecting a switcher input via the category and selection keypad. If level selection is
required, use the LEVEL menu selection mode. In other words, input selection must be complete but TAKE is not pressed.
The operator then presses MENU and MORE to display the DEFINE override soft−key. This displays the first page of existing
override names. The operator then selects the override to be edited by pressing the corresponding function key. The MORE
push button is pressed if the desired override name is on another page.
Note: Only existing overrides can be edited. The override cannot be entered on an empty display position.
If entry of a password is requested, please see Passwords on page 6−22.
Important: This procedure does not change the name of the override as established by the Override Set table. This
could result in a situation where the operator selects CAM1 but gets VTR5. For overrides that will be allowed to
be to be edited from the front panel, it is a good practice to use generic names such as “Usr1” or “Ovr1”on the
Override Set table.
ID — DISPLAY CONTROL PANEL DEVICE ADDRESS
The panel ID menu selection displays the system address used to select and service this control panel. The ID is determined
at time of panel manufacture and cannot be changed by the operator.
The operator presses MENU, MORE (twice), and then the ID soft−key. The display prompt line is cleared and the current
control panel identification is displayed. (See Figure 6−25.) The display remains until the operator presses CLEAR or TAKE.
