NV9642 Panel Description
The NV9642 is a control panel featuring 34 LCD function buttons (illuminated in various colors
and having 1 to 3 lines of text) and a small vacuum fluorescent display having 4 lines of 22 char-
acters. It can operate in X-Y mode or in multi-destination (MD) mode. Operators can switch
between modes at any time. Up and down buttons allow you to scroll the display:
At the rear, in addition to power, serial, and network connectors, is a 25-pin GPIO (tally)
connector that supports 4 optically isolated relay outputs and 8 optically isolated inputs:
An equivalent NV9642V — a “virtual panel”— is available. It emulates the NV9642.
The NV9642 provides a tree-structured (or hierarchical) button layout. Configurers can define a
“tree” of buttons in such a way that each of the 30 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 34 button functions at any partic-
ular level in the tree.)
Configurers use ‘Navigate’ buttons to create new button pages (subtrees). During operation,
NV9642 users press such buttons to access different subtrees.
The panel can also display predefined button pages. For instance, a “category” button, when
pressed, will display one or more pages of sources or destinations through which the operator
may browse. A “menu” button presents a page of menu options.
Function Buttons
The NV9642 has two rows of 17 LCD buttons — a total of 34 LCD buttons. Each has 3 lines of text.
The buttons can display one of seven colors dynamically: nominally red, green, blue, purple,
amber, yellow, or grey. If the button text occurs on only one or two lines, the button displays
larger text, centered on the button.
Each LCD button has three operational levels: high tally, low tally, and off.
Some buttons functions are assigned by the system depending on the context. 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, viewable data are displayed on the LCD buttons.
