Operation
Summary
At any particular time, some of the buttons are enabled or disabled. Some are high-tally; some
are low-tally; and some might be off (undefined). The buttons have different colors, the choices
of which depend on the configurer’s intentions.
S Please refer to the NV9000-SE Utilities User’s Guide (or the NV9000-SE Utilities help files) if you
are unfamiliar with the concepts used in this chapter.
Modes of Operation
The panel operates primarily in either “X-Y mode” or a “multi-destination mode.” An XY/MD
button can toggle between the modes. (The configurer can specify the default mode.)
The primary modes of operation are:
• X-Y mode — individual control of router levels . Choose a destination, optionally choose
desired breakaway levels, choosing a source or sources, and press ‘Take’ to complete a
desired route. Sources are taken only on selected levels.
• Multi-destination (MD) mode — lets you view and control multiple destinations. The button
tree presents destination devices on selection buttons. You can scroll through the MD device
list using ‘Page Up’ and ‘Page Down’ buttons. Select one or more MD devices, choose a
source, and repeat for all desired routes. Then press ‘Take’. Takes are “all level,” and break-
aways cannot be performed.
MD mode allows you to make multiple routes in a single take.
• Single-destination mode — A single destination is defined during configuration. You have
only to choose a (quick) source. The take is automatic when you are using quick sources.
Single-destination mode is not a distinct mode and actually need not involve only a single
destination. It can be combined with X-Y mode or multi-destination mode.
Secondary modes are:
• Setup mode — where the NV9640A is freshly powered up, but disconnected from the network .
In this mode, the configurer can preset the NV9640A’s panel ID and perform a few diagnostic
tasks.
Usually, only configurers need be concerned with setup mode.
See Setup Mode on page 73.
• Salvo mode — pressing a ‘Salvo’ button and then a ‘Take’ button executes a salvo. The dura-
tion of a salvo is indeterminate.
•
Menu mode — pressing a ‘Menu’ button places the NV9640A in “menu” mode. In menu
mode, the LCD button array becomes a menu button panel that changes as needed during
menu operation. Some menu data are presented on the alphanumeric display.
There is nothing in the menu that concerns operators except LCD brightness. An operator
may use the menu to set LCD brightness. Administrators and configurers may use the menu
to view or change the panel ID, or to determine the software and firmware revisions.
See Menu Mode on page 70.
Button Legends
There are many different button function types (about 32) and the legend that appears on any
button varies with the type and depends on the configurer’s intentions. Button legends have 3
lines of 8 characters. One or more lines of a button legend can be blank.
