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

A category button selects a category. 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.
Source category buttons operate in level mode; destination category buttons do not.
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 not disabled in either mode.
Category buttons that have only a suffix configured are disabled until a category becomes
selected.
A typical NV9649 configuration has a "keypad" 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.
The names of devices in categories are composed of the category name followed by one or
more digits or suffixes. NV9000-SE Utilities allows configurers to designate a separator
character which is inserted between the parts of the device name. (Device names are
limited to 8 characters, however.)
You cannot perform a name set change using a 'Nameset Toggle' button while a cate-
gory selection is in progress.
