NV9640 (and NV9640A)
Panel Description
 The NV9640A is a revision of the NV9640 that uses slightly different LCD buttons. Otherwise,
the NV9640A is the same as the NV9640. NV9000-SE Utilities does not list an NV9640A. For
an NV9640A, choose an NV9640 configuration.
The NV9640(A) is a control panel (2RU) featuring 30 LCD function buttons (illuminated in various
colors and having 1 to 3 lines of text) and a small vacuum fluorescent display having 8 lines of 42
characters. It can operate in X-Y mode or in multi-destination (MD) mode. Operators can switch
between modes at any time:
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 NV9640V — a “virtual panel”— is available. It emulates the NV9640 (and the
NV9640A).
The NV9640(A) provides a tree-structured (or hierarchical) button layout. Configurers can define
a “tree” of button pages 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 30 button functions at any partic-
ular place in the tree.
(Configurers use ‘Navigate’ buttons to create new button pages (subtrees). During operation,
NV9640(A) 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.
