Control Panels
NV9654
An equivalent NV9654V — a “virtual panel”— is available. It emulates the NV9654.
The panel can be configured in either of two behavioral modes:
• ‘Display and Button’ mode
• All-Button mode
Under ‘Display and Button’ mode, the left-most 15 buttons function as an alphanumeric display.
These buttons display the same information as some other panels that have displays, such as
the NV9640. Under this mode, the panel operator can turn the “display” on and off. When the
display is off, the 15 buttons can have other configured functions. (It is with the ‘Toggle Display’
button that the operator hides or reveals the display.)
Under ‘All-Button’ mode, the panel provides no display. Note that under ‘Display and Button’
mode, the panel has 3 additional button functions that relate to the display.
The panel can operate in X-Y mode or in multi-destination (MD) mode. Operators can switch
between modes at any time.
The NV9654 provides a tree-structured (or hierarchical) button layout. Configurers can define a
“tree” of button pages in such a way that each of the 54 LCD buttons 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 54 button functions at any partic-
ular place in the tree. A panel that is configured in ‘Panel and Button’ mode shows the “display”
only on the top level page of the button “tree.”
Configurers use ‘Navigate’ buttons to create new button pages (subtrees). During operation,
NV9654 users press such buttons to access different subtrees.
The panel can also display predefined button pages. For instance, a “category” button, when
pressed, can display one or more pages of sources or destinations through which the operator
may browse. A “menu” button presents a page of (pre-defined) menu options.
Function Buttons
The NV9654 has an array of 54 LCD buttons. Each button has 1, 2, or 3 lines of text. When there
are one or two lines of text, the characters are large; when there are 3 lines of text, the characters
are smaller. The buttons can display one of seven colors dynamically: nominally red, green, blue,
purple, amber, yellow, or grey.
Each LCD button has three operational levels: high tally, low tally, and off.
Some buttons functions are assigned by the system. For example. the panel software adds a
“forward” button and a “back” button if there are more sources than buttons on a category
page.
The LCD buttons display a menu if the operator presses a menu button. When the operator
make a menu selection, the panel displays viewable data on the LCD buttons.
Configurers can define ‘Selection’ buttons that select a level or an MD device. (They must do so if
the operator is to make such selections.)
Scrolling is necessary when a list of items — for instance, levels or MD devices — exceeds the
number of buttons available for the items. Panels that use multi-destination mode will probably
require ‘Page Up’ and ‘Page Down’ buttons.
