Summary
The NV9641
1
is a 1RU control panel featuring 16 LCD function buttons (illuminated in
various colors and having 1 to 3 lines of text) and 2 up/down (scroll) buttons.
This 1RU panel is organized as shown in figures 2-1 and 2-2:
Fig. 2-1: NV9641 Front
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:

Behavioral Models
Configurers can place the NV9641 in one of two behavioral model: XY/MD and paging. The
behavioral models are distinct and it is not possible for the operator to switch from one
model to the other.

a GUI that is called a “virtual panel”—
is available. It emulates the NV9641.
