Operation
Operating Concepts
Making a Category Selection
1 Put the panel in source mode or destination mode as required. (Note: you must select a des-
tination first, then the source, then press ‘Take’— unless your panel is a single-destination
panel where the destination is always pre-selected.)
2 Press a category button that will initiate a category selection. The category name will appear
in the ‘Preset’ field of the display.
3 Press one more category buttons that append a suffix to the device name in the ‘Preset’
field.
4 Stop when your device name is complete. Proceed with other operations.
Example: To select the device SAT_A12, press a ‘SAT’ category button, followed by an ‘A’ suffix
button, followed by a ‘1’ suffix button and a ‘2’ suffix button. The underbar would be automati-
cally generated. Depending on the NV9000 configuration, other such fill characters might be
used.
Source and Destination Modes
Category device selection is affected by source mode and destination mode. In source mode,
only source categories are selectable. In destination mode, only destination categories are
selectable. (Some devices, such as VTRs, are both sources and destinations.)
There are 3 button types that affect category device selection:
• Source Mode — places the panel in source mode.
• Destination Mode — places the panel in destination mode.
• Src/Dst Mode — toggles the panel between source mode and destination mode.
It is likely that your panel will have a ‘Src/Dst Mode’ button and neither of the other two.
Levels
In NV9000-SE Utilities and in the NV9000 router control system, routes occur on levels. A level is
typically SD, HD, analog video, AES, analog audio, or machine control. Various devices are
defined as sending and receiving signals on certain levels. The set of levels handled by a device
belong to what is called a level set.
A source can be routed to a destination if it has the same set of levels, i.e., it belongs to the same
named level set. A source can be routed to a destination in a different level set if the NV9000
configuration has the appropriate inter-level set mapping.
The effect of this is that when you, the operator, choose a destination, the NV9000 software
recognizes which source devices are allowed to be routed to the destination and limits your
selection to those sources.
Breakaway
Routes can be all-level in which case they are taken on all levels defined for the destination. The
acceptable sources for a route have the same levels as, or some configured mapping to, the
levels of the destination.
A breakaway is where you take different sources to the same destination — on different levels. In
most cases, you would take only certain levels of a new source to a destination that already has
a source on its various levels.
