Paging Model
Under this model, the NV9641 provides a set of button pages, through which the operator may
scroll using the up/down buttons. In this case, the term “button page” means a set of buttons
accessed by the up/down buttons. In this model, the button pages are
not organized as a tree.
There are no navigation buttons under paging mode.
Function Buttons
The NV9641 has an array of 16 LCD buttons. The buttons can display one of seven colors dynam-
ically: nominally red, green, blue, purple, amber, yellow, or grey.
Each LCD button has three operational levels: high tally, low tally, and off.
Some buttons functions are assigned by the system. For example. the panel software adds a
“forward” button and a “back” button if there are more sources than buttons in a category page.
The LCD buttons display a menu if the operator presses a menu button.
Configurers can define ‘Selection’ buttons that select a level during a breakaway setup or that
select destinations in multi-destination (MD) mode. (You must do so if the operator is to make
such selections.)
Up/Down Buttons
The two small backlit buttons (next to the printed arrows) illuminate when scrolling is possible.
The up button illuminates when you can scroll up; the down button, when you can scroll down.
Scrolling is necessary when a list of items exceeds the number of buttons available for the items.
Operators use the up/down buttons to view different button pages when the panel is config-
ured according to the paging model.
Tally Interface
At the rear of the panel is a DB25 connector that provides 8 tally inputs and 4 tally outputs. (The
outputs are solid state relay outputs.) Both inputs and outputs are optically isolated.
See GPIO on page 197.
Modes of Operation
Under the paging model, the panel operates in a limited X-Y mode only.
The primary modes of operation are:
• X-Y Mode — individual control of all router levels. Choose a destination, optionally choose
desired breakaway levels, choose a source, and press ‘Take’ to complete a desired route.
• Single-Destination Mode.
Single-destination” mode is not a distinct mode, but it is a mode on some other panels and
can be simulated on the NV9641. It can be combined with the other two modes.
• Limited X-Y Mode.
When the panel is configured according to the paging model, we can say it is in limited X-Y
mode. In limited X-Y mode, takes are all-level and apply to a single destination.
• Multi-Destination Mode — lets you control multiple destinations. The LCD buttons display
destinations and sources. Select a destination, choose a source, and repeat for all desired
routes. Then press ‘Take’. Takes are “all level,” and breakaways cannot be performed.
