Summary
The NV9642
1
is a hierarchical 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 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.
1. An equivalent NV9642V — a GUI that is called a “virtual panel”— is available. It emulates the NV9642.
