Broadcast; Category - GRASS VALLEY NV9649 User Manual

A back button may have any legend and be any color, but typically its legend is just "BACK"
and typically, its color is blue, as it is for back buttons generated automatically for lists. A
back button is never high-tally.

Broadcast

A broadcast button applies to a data (or machine control) level only. The button assigns one
controlling device (the master) to multiple controlled devices (the slaves). The function is
useful in dubbing applications. See

Pressing the 'Broadcast' button turns off the 'Source is Master' button and vice versa.
The default button text is "Broadcast" but a broadcast button can have any legend.

Category

Each category button represents (1) either a source category or a destination category, and
(2) a device suffix (or a numerical index).
A category button displays 2 lines of text: (1) a source category name when the panel is in
source mode or a destination category name when the panel is in destination mode, and
(2) its suffix text. If the button has no suffix text, the second line shows dashes.
A category button selects a category for the purpose of device selection. In source mode, it
selects a source category. In destination mode, it selects a destination category. After you
press a category button, you must then press number or suffix buttons to perform a device
selection within the category. You may also use scroll buttons ('Page Up' and 'Page Down')
to select device indexes and suffixes within the category if the panel has scroll buttons.
When the panel is in source mode, a category button places the category mnemonic in the
'Preset' display. As you enter suffixes to select a source, the name of a source constructed
from the category name and suffixes thus far entered appears in the 'Preset' field.
In destination mode, a category button places the category mnemonic in the 'Preset'
display. As you enter suffixes to select a destination, the suffixes are appended to the
contents of the 'Preset' field, and the name of a destination constructed from the category
name and suffixes thus far entered appears in the 'Destination' field.
When the panel is in source mode, category buttons that are not configured with a source
category become disabled. When the panel is in destination mode, category buttons that
are not configured with a destination category become disabled. Category buttons
configured with both source and destination categories are available in either mode.
Category buttons that have only a suffix configured are disabled until a category becomes
selected and the set of device names in the category include the digit or suffix on the
button. If, for example, the devices in the category number from 1 to 7, buttons for the
digits 8 and 9 will be disabled.
A typical NV9649 configuration has a "keypad" — possibly on a suffix page — with which
you can enter device indexes or suffixes. Keypad buttons are actually category buttons. Any
keypad button can also be a source category button and a destination category button.
 Note that category buttons in server mode function differently from category buttons
under LCD XY/MD mode and NV9609 mode. There are differences in the configuration
of these buttons too.
