Configuration
Commitment Buttons
• Create pages (subtrees) of buttons. (Do this using the Navigation button type).
• Define logic for some or all of the tally inputs and outputs.
A configuration should lead the operator through required tasks. It is possible to make naviga-
tion through the tree structure of panel operations intuitive through the judicious use of color
and text on the LCD buttons.
The configurer must keep in mind that the operator generally cannot view the entire button
tree at a glance.
The configurer must also keep in mind that the operator must be able to reach any page in the
tree. In particular, the operator, having navigated down a subtree, must have some way to navi-
gate back up the subtree. There are several ways to ensure this. Two are listed here:
•
Place a “Back” button on each subpage. The “back” button causes the NV9640 to redisplay
the
previous page.
• Place a “Navigate” button on each page, where the navigate button causes the NV9640 to
display a
specific page.

The operator can always return from system-generated pages (e.g., device lists) using the
‘back’ button.
The panel operator, in most cases, needs a ‘Take’ button and at least one selection button. In
addition to their basic function, selection buttons provide feedback about the preset source
device and level mapping. A ‘Clear Preset’ button is strongly recommended.
 We recommend that you place exactly 8 selection buttons on a page and that they reference
all display indexes.
Commitment Buttons
Two buttons at the bottom of the configuration page are self-explanatory and present on most
configuration pages:
• Revert to Saved. Press this button if you want to discard any recent changes you have made.
• Save. Press this button to commit all your recent changes.
Neither of these actions is reversible.
