•
A
source
is a set of inputs on one or more routers, on one or more levels. The inputs might, or
might not, belong to a single physical device.
•
A
destination
is a set of outputs on one or more routers, on one or more levels. The outputs
might, or might not, belong to a single physical device.
•
A
salvo
is a sequence of primitive takes. The takes execute, in order, when a panel operator
presses a salvo button. A primitive take in a salvo comprises 3 values: level, input, and out-
put. A primitive take routes a single input to a single output on a single level.
•
The
primary level
is the first level defined for a particular destination.
•
The
precedence
of level buttons depends on the location of the level buttons on the panel.
In general terms, level buttons have higher precedence if they are to the left of, or are above,
other level buttons. (Precedence governs which sources and destinations become enabled
for selection on a panel that is configured in standard mode.)
•
A
normal take
is a non-breakaway take.
Operators control a CR6400 system using remote panels. An operator is presented with a large
and potentially bewildering array of buttons. It is the configurer’s task to produce a panel that is
easy to understand and to use:
•
When your system has multiple panels, exercise caution so that you do not create panel con-
figurations that conflict with each other.
•
Avoid configuring source buttons and destination buttons that do not match the actual
router connections and the numbering given by the router partitions.
•
Create meaningful button legends that accurately describe what the buttons do. There are
button templates available on the installation CD (SB0033-
xx
).
Remote Panel Modes
Remote panels operate in one of three modes: (1) standard mode, (2) enhanced mode with
hold, and (3) enhanced mode without hold.
Standard Mode
In standard mode, takes are performed on (manually) selected levels only.
Level selection is persistent and at the discretion of the panel operator. Once the operator
makes a level selection, it remains until the operator changes the selection. The current level
selection enables some sources and destinations and disables others. The sources and destina-
tions that are enabled depend on which level button has
precedence.
See
Button Order
on
page 53 for information about precedence.
If no levels are selected, no sources or destinations are enabled. A take cannot occur.
If the panel has no level buttons, all of a destinations’ levels are always selected and all destina-
tions are enabled.
Which level button has precedence depends on the order of level buttons on the panel and the
order in which the operator presses the level buttons. See
Button Order
on page 53.
Standard mode allows breakaway. A breakaway is when you route to some, not all, of a destina-
tion’s levels. By default, all valid levels are automatically selected when you set up a take. By
creating a breakaway, you route only to the levels you have individually selected.
