Overview
Enhanced Mode (Hold and No-hold)
‘Takes’ are performed on all the levels specified by the destination.
In enhanced mode, level selection is applicable only to breakaway. Level selection governs the
selection of sources for the breakaway. All sources and destinations are always enabled. The choice
between hold mode and no-hold mode is meant to accommodate operator preferences.
Enhanced mode has 2 submodes:
• Hold mode — the level selection persists after the destination button is pressed and until the
operator changes it. This allows an operator to try different sources. To clear a breakaway, start
a new normal take to that destination.
• No-hold mode — a level selection reverts to the levels defined by the destination after the oper-
ator presses a source button. To clear a breakaway, either start a new normal take to that desti-
nation or press a source without a level selection.
About Salvos
A “salvo” is a list of preset actions or routes. Usually these are routes that are commonly repeated
over and over. By assigning a salvo to a button, an operator need only press the one button rather
than several to perform a route. When an operator presses a salvo button, the ‘takes’ execute very
rapidly and in sequence, but not 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.
A salvo can include up to 32 basic ‘takes’. A panel configuration can have up to 32 individual salvo
buttons. 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.
Important CQX panels are not configurable through CRSC at this time.
