Operation
Summary
Because the panel's buttons can have arbitrary legends, a button's legend might or might not
indicate its function. Operators and configurers will have to communicate about the meaning of
the buttons in the button tree.
Physically, you will find
• Navigation buttons to go up or down in the button tree, or to a specific page in the tree.
•
Function buttons (e.g., select a source or lock a destination).
•
Lists of sources, destinations, source categories, destination categories, or salvos.
•
Sets of virtual level buttons (in X-Y mode) or sets of MD destinations (in MD mode).
•
Two scroll buttons (up and down).
At any particular time, some of the buttons are enabled or disabled. Some are high-tally; some
are low-tally; and some are off (undefined). The buttons have different colors, the choices of
which depend on the configurer's intentions and on Grass Valley convention.

Please refer to the other router system documentation if you are unfamiliar with the
concepts used in this chapter. See

Modes of Operation

Because the panel operates under either the XY/MD or the paging model, we can say there are
four primary modes. Under the XY/MD model, the panel operates in either "X-Y mode" or a
"multi-destination mode. " A single button (XY/MD) can toggle between the modes. (The config-
urer can specify the default mode.)
Under the paging model, the panel operates in limited X-Y mode only.
The primary modes of operation are:
• X-Y mode — control of individual router levels. Choose a destination, optionally choose
desired breakaway levels, choose a source, and press take to complete a desired route.
Sources are taken only on selected levels.
•
Multi-destination (MD) mode — control of multiple destinations. The button tree presents
MD destination devices on selection buttons. You can scroll through the MD device list using
the 'Up' and '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 breakaways cannot be per-
formed.
MD mode allows you to make multiple routes in a single take.
•
Limited X-Y mode — individual control of router levels. Choose a destination, optionally
choose desired breakaway levels, choose a source, and press take to complete a desired
route. Sources are taken only on selected levels.
• Single-destination mode — not a distinct or a real mode, but a specific way of using any of
the other modes. Single-destination mode is typically an application of 'Quick Source' but-
tons.
Secondary modes are:
• Setup mode — where the NV9641A is freshly powered up, but disconnected from the network.
In this mode, the configurer can preset the NV9641A's panel ID and perform a few diagnostic
tasks.
Usually, only configurers need be concerned with setup mode.
