Button Definitions - GRASS VALLEY NV9640 User Manual

•
Jump back after destination selection.
After you make a destination selection, the panel reactivates the default button page.

Jumping back to the default page is usually helpful, but in some configuration designs,
might not be. You can design your panel configuration to take advantage of the jump-
back behavior.
• Src/dst immediate take.
A 'Src/Dst' button connects a source to a destination. When this box is checked (as it is in the
default NV9640 configuration) the button performs an immediate take. When the box is
clear, the button sets up the take and the operator must press a 'Take' button to complete
the take.
•
Page VFD only.
You can configure the panel so that when the operator presses 'Page Up' or 'Page Down' ,
either the display (a vacuum fluorescent display or VFD) scrolls, the items on selection but-
tons scroll, or both the display and the items on the selection buttons scroll:
Scroll the VFD only
Scroll either the VFD or
the selection buttons
Scroll both at the same
time

Button Definitions

There are four classes of button functions:
• Dedicated functions, such as 'Default State' or 'Chop' .
•
Variable functions, such as 'Category' or 'Source' . With this type of button, additional selec-
tions are needed to complete the button configuration.
•
Special functions, such as 'Navigate' and 'Back' . These functions allow the panel operator to
move from one button page to another. (The Navigate button is unique: it initiates a dialog
in which you create a subtree.)
• System-generated button functions. These are buttons that are generated dynamically (by
the router control system) during operation. An example of system-generated buttons is a
device list generated when the user presses a category button. The set of devices in a cate-
gory can change over time (as the configuration database changes); the NV9640 device list
changes also.
The number and names of categories can also change over time and the NV9640 will track
those changes too.
