Operating in an NV9000 Network

In an NV9000 router control system, it is the system controller that is the focal point of the
system
— the “clearing house” for all commands and responses. Remote panels are compara-
tively simple panels under NV9000. Their function set includes these buttons:
• Source
A source button represents a source device (which provides a set of inputs to the NV9000
network. The devices do not necessarily have to be connected to compact routers.
• Destination
A destination button represents a destination device (which comprises a set of outputs in the
NV9000 network. The devices do not necessarily have to be connected to compact routers.
• Salvo
In the context of CR Series remote panels, a salvo is system salvo (as opposed to a “local”
salvo or any other kind). A system salvo is a sequence of NV9000 commands, such as Take,
Lock, Release, or Pause, that executes when the salvo button is pressed. System salvos are
stored in the system controller. System salvos are defined in NV9000-SE Utilities.
 Note that NV9000 system salvos are not the same as CRSC salvos.
• Previous source
A ‘Previous Source’ button is like an “undo” button: when you press it, the connection(s) to
the source(s) previously routed to a destination is restored.
• Undefined.
Some remote panel buttons can be left undefined. These buttons do nothing and are unlit.
A remote panel under an NV9000 network is not the same as a remote panel under a CRSC
network.
A remote panel has two further considerations (during configuration):
• Default destination.
The default destination is a destination selected for the panel at power-up. That destination
remains selected until an operator selects another destination at the panel.
• Status monitor.
The status monitor is a destination device (such as a video monitor) on which the output(s)
of the currently selected destination are replicated. When you select a different destination,
the status monitor output reflects that change. When you select a different source for a des-
tination, the status monitor output reflects that change also.
Modes
Because of the possibility of a default destination, a remote panel can function in two ways: as a
m × 1 panel or as m × n panel.
• Takes under an m × n setup require an operator first to press a destination button, then a
source button.
• Takes under an m × 1 (i.e., a single-destination) setup require an operator to press only a
source button.
These are the minimum. Breakaway takes can involve much button pressing to select sources
for different levels.
