Essential Information
Enhanced mode has 2 submodes:
•
Hold mode
—
the level selection persists after the destination button is pressed (initiating a
take) and continues indefinitely until the operator changes it. This allows an operator to try
different sources. To clear a breakaway, the operator starts a new normal take (non-break-
away) to that destination. See
•
No-hold mode
—
a level selection reverts to the levels defined by the destination after the
operator presses a source button (completing a take). To clear a breakaway, either start a
new normal take to that destination or press a source without a level selection. See
The choice between hold mode and no-hold mode is meant to accommodate operator or
administrator preferences.
Salvos
A “salvo” is a sequence of primitive (or simple) takes. Salvos are usually defined because their
operations are commonly repeated often. By assigning a salvo to a button, an operator need
only press the one button to execute the entire take sequence. When an operator presses a
salvo button, the ‘takes’ execute very rapidly and in sequence, but not quite simultaneously. The
salvo button lights turns bright during the salvo execution and returns to dim at completion.
Salvos do not:
•
Execute source selections, destination selections, or level selection functions.
•
Execute other salvos. (That is, salvos cannot be nested.)
•
Contain loops or branches.
A simple take is expressed in CRSC as 3 values: level, input and output. These three values
uniquely define a crosspoint in the set of routers and router partitions.
For control panels other than the CP32-6464, CP6401, or CP6464, a salvo can include up to 32
primitive takes. A panel configuration can have up to 32 individual salvo buttons. (In practice, a
panel would rarely have that many salvo buttons.) Each panel can have a different set of salvos.
For the CP32-6464, CP6401, or CP6464, which control the 64×64 matrices of CR6400 routers, a
salvo can include up to 64 primitive takes and a panel configuration can have up to 64 individual
salvo buttons, subject to a total of 1024 primitive takes. (For example, a panel could have 16
salvos of 64 takes or 64 salvos of 16 takes or some other combination.) Each panel can have a
different set of salvos.
If multiple salvos execute simultaneously, it is likely that their effects will be in conflict. There is
an exception: if two or more salvos have no outputs in common, they can safely run at the same
time. It is not possible to execute multiple salvos simultaneously from a single panel.
If a salvo attempts an impossible take (e.g., one on a non-existent level), it will try the take and
wait for a response 5 times before proceeding. This means that salvos that have errors take
noticeably longer to execute than salvos without errors. A salvo without errors should take only
a fraction of a second to execute.
Paging
Certain CR Series control panels can have buttons that control the presence or absence of sets of
sources and destinations that can be controlled by the panel. We call these sets of sources or
destinations “pages.”
