(AES/EBU (Audio Engineering Society/European Broadcasting Union). AES and EBU are standards
organizations.
Breakaway A condition where a destination has multiple sources on different levels.
Category A category represents a set of devices. (The concept of categories exists to make it easier to
select devices at a control panel.) A category can contain sources, destinations, or devices
that are both sources and destinations. Each device in the category has a unique selection
index within that category. Each category has a mnemonic ID associated with it.
The NV9649 does not support categories or category selection.
Data routing Data routing (a.ka., machine control routing) is a bidirectional form of routing. Routes are
characterized by a controlling device and controlled device(s). The NV9649 provides certain
data routing options including a 'Broadcast' button.
Device A "device" is a grouping of input and output ports that define a logical entity. (The logical
entity often represents a real device, but it does not have to be a real entity.) For example, a
system might have 3 levels: video, AES, and time code. A hypothetical device in this system
is Camera 1, which consists of video on input port 1 of the video router, AES on input port 5
of the AES router, and time code on input port 8 of the time code router.
GPIO General Purpose Input and Output. A generic term for the NV9649's tally interface. The tally
interface is called the "GPI Interface" at the rear of the NV9649.
Level set A level set is a group of virtual levels that are commonly used together when switching
devices. A level set also defines the mapping of each virtual level within the level set to a
single physical level. All levels in a level set have a unique display index within that level set.
Multi- A mode on an NV9000 control panel that presents many destinations at once, in contrast to
Destination X-Y mode. An operator may route sources to multiple destinations in a single take. Multi-
(Mode) destination mode does not permit the selection of breakaway levels.
Operator The term operator (a.k.a. user) usually refers to users other than the system administrator or
configurer. An operator is responsible for making the routes.
Physical level Multiple routers provide different "physical levels" on which to switch the signals of devices.
Any particular device might send or receive HD, SD, AES, time-code, or machine-code
signals.
PIN The system administrator may create a single "super user" personal identification number
(PIN) that functions as a passcode. A PIN is 4–6 digits in length. The PIN allows certain
operators to perform functions such as (1) forced release on a control panel that is
configured for normal release or (2) changing the ID of a control panel.
Port A port is the physical connection on a router. A port can only be an input port or an output
port.
Salvo A salvo is a stored group of commands that can be recalled and executed at an NV9000
control panel.
