Button Functions
The NV9649 has 3 behavioral models. The sets of button functions differ in the 3 models.
Buttons for the Server Model
There are 16 button function types for a panel in server mode (not counting ‘Undefined’):
Assign Broadcast Category Chop
Clear Destination Lock Destination Mode Destination Protect
Menu Quick Source Salvo Source
Source Mode Src/Dst Mode Take Take All
Assign
When the panel is in destination mode, the button begins the assignment of a selected destina-
tion to an NV9648 control unit.
When the panel is in source mode, the button begins the assignment of a selected source to a
source button of an NV9648 control unit.
See Operating Methods on page 110 for detail.
 Destinations and sources assigned with this function are preserved (in the system controller)
even when power fails. Destination and source assignments can be grouped into different
sets to be used perhaps by different users or at different times of the day, or for any reason.
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
Broadcast Routes on page 90 for more information.
 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 3 items: a source category, a destination category, and a device
suffix (or a numerical index).
A category button displays 2 lines of text: (1) either the source category name when the panel is
in source mode, or the 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.
When you first press a category button, the category mnemonic appears in the ‘Preset’ display.
After the category is thus selected, you uses a keypad (which is a button array) to enter the
device index within the category. (The keypad is a set of category buttons to which indexes or
suffixes have been assigned.)
(Typically the category buttons are arranged to form a keypad on your panel in which the digits
or suffixes are logically arranged.)
Pressing a category button when the panel is in source mode starts the “construction” of a
source device name. Pressing a category button when the panel is in destination mode starts
the construction of a destination name.
