Summary
The NV9642
1
is a hierarchical control panel featuring 34 LCD function buttons (illuminated in var-
ious colors and having 1 to 3 lines of text) and a small vacuum fluorescent display having 4 lines of
22 characters. It can operate in X-Y mode or in multi-destination (MD) mode. Operators can switch
between modes at any time. The up and down buttons allow you to scroll the display.
This 1RU panel is organized as shown in figures 2-1 and 2-2:

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:

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 particular
level in the tree.
1 An equivalent NV9642V — a GUI that is called a “virtual panel”— is available. It emulates the NV9642.
