Introduction
Panel Organization
Behavioral Models
Configurers can place the NV9641A in one of two behavioral model: XY/MD and paging. The
behavioral models are distinct and it is not possible for the operator to switch from one model
to the other.
XY/MD Model
Under this model, the NV9641A provides a tree-structured (or hierarchical) button layout. You
can define a “tree” of buttons in such a way that each of the 16 LCD buttons (illuminated in
various colors and having 1 to 3 lines of text) can either (1) execute a function or (2) select a
subtree (i.e., present an entirely new set of functions at a different level in the tree). The tree,
with its subtrees, is not limited in size.
We use the term “button page” or “page” to mean the set of 16 button functions at any partic-
ular place in the subtree.
Configurers will use ‘Navigate’ buttons to create new button pages (subtrees). During operation,
NV9641A users will press a ‘Navigate’ button to access a subtree. However, ‘Navigate’ buttons
are typically not labeled “Navigate”; they would be labeled according to the specific function
they perform in your system.
 The up/down buttons scroll through lists of devices, through levels in X-Y mode, and
through pages of multi-destination devices.
When the operator is scrolling through devices, and is at the first page of devices, the up
button returns the panel to the “parent” page
— the page that contained the category but-
ton that accessed the device pages.
Paging Model
Under this model, the NV9641A provides a list of button pages, through which the operator may
scroll using the up/down buttons. In this case, the term “button page” means a set of buttons
accessed by the up/down buttons. The button pages are not organized as a tree. There are no
navigation buttons under paging mode.
The paging model has fewer functions than the XY/MD model.
Panel Organization
Function Buttons
The NV9641A has an array of 16 LCD buttons. Each has 3 lines of text (up to 8 characters per
line). The buttons can display one of seven colors dynamically: nominally red, green, blue,
purple, amber, yellow, or grey. We say a button is “dark” when its LCD is turned off.
During configuration, you can assign any of the 7 colors to a button.
Each LCD button has four levels of brightness: off, low, medium, and high, and supports three
operational levels: high tally, low tally, and off. High tally can be either medium or high bright-
ness and low tally can be either low or medium brightness. High tally is always constrained to be
brighter than low tally. See
LCD Buttons , page 85, for a color chart.
Although a configurer can see the tree or list of pages during configuration, the structure of the
button pages is not evident on the panel itself. The panel operator must commit the structure to
