User’s Guide
Configuration Tasks
The person configuring an NV9641 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
navigation 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 NV9641 to
redisplay the
previous
page.
•
Place a “Navigate” button on each page, where the navigate button causes the NV9641
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.
