User’s Guide
If a breakaway occurred (in X-Y mode) for a particular destination, the MD destination
button shows the destination mnemonic in reverse-field.
Lists
The NV9641 can display devices, categories, and salvos in automatically generated lists
under the XY/MD model. There are three kinds of lists:
• Generated during configuration of a navigation button. These lists are characterized by
the presence of “Back” and “Forward” buttons in the list. Traverse these lists by pressing
the back or forward buttons. A final “back” returns to the page containing the button
that displayed the list.
• Automatically generated as the result of pressing a category button. These lists are
characterized by the activation (and illumination) of the up and down buttons. Traverse
these lists by pressing the up and down buttons. A final “up” returns to the page
containing the category button that displayed the list.
• Virtual levels or MD devices presented on selection buttons. These sets are also
characterized by the activation (and illumination) of the up and down buttons.
 Automatically generated device lists, category lists, and salvo lists do not exist under
the paging model.
Operating Concepts
Levels
In the 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 level mapping.
The effect of this is that when you, the operator, choose a destination, the system controller
recognizes its levels and 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 can occur in X-Y mode. A breakaway is where you take different sources to the
same destination
— on different levels.

The reverse field lets you know that this destination has a
breakaway take. The top line of text represents the source for
the breakaway on the primary level of the route.
