Configuration Tasks
The person configuring an NV9641A panel will want to consider how best to use the button
page tree under the XY/MD model or the list structure of the button page list under the paging
model to support the devices and routers in the router control system at hand. The task is non-
trivial. The paging model is simpler but the XY/MD model is richer.
In support of that effort, the configurer will do the following:
• Select panel options.
• Assign functions to buttons.
• Create pages (subtrees) of buttons. (Do this using the Navigation button type).
• Define logic for some or all of the tally inputs or outputs.
A configuration should lead the operator through required tasks. It is possible to make naviga-
tion of the panel 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
page structure at a glance.
For XY/MD configurations, and for global navigation templates, 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 navigate 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 NV9641A to redisplay
the previous page.
• Place a “Navigate” button on each page, where the navigate button causes the NV9641A to
display a specific page.
 The operator can always return from system-generated pages (e.g., device lists) using the
‘up’ button.
For paging configurations, the operator can always use the up and down buttons to move from
page to page.
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 also recommend that you place exactly 8 selection buttons on a page.
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.
