Introduction
9284 Functional Description
“X”: Connect Crosspoint
The command “X” is used to request that a connection be made. It must be
followed by an output number, a comma, an input number, a comma, and a
level number.
For example, the command:
**X24,13,2!!
says that a connection is to be made between output 24 and input 13 on level
2. If the level number is specified as “0”, this means that the connection is to
be made on all levels (AFV).
For example, the command:
**X8,3,0!!
says that a connection is to be made between output 8 and input 3 on all
levels.
An input number of 0 means the output connection is to be left unchanged,
not very useful in an “X” command.
An input number of '-' (dash) means the output is to be disconnected. If the
router does not support disconnected outputs, the output connection will be
left unchanged. When a level number of 0 is used with the “X” command, it
can be assumed that the switcher software guarantees to send all level
changes for the output to the crosspoint matrix within the same vertical
interval, unless otherwise noted in the documentation for a specific switcher.
It is an error to request connection of an input or output that doesn't exist on
the specified level, even if it does exist on some other level. However, if the
level number is “0”, any input or output number may be specified as long as it
exists on at least one level, and in that case no connection will be made on any
level on which the input or output does not exist. If the requested connection
has an output or input number that isn't mapped to a physical connector (on
virtual-mapped routers) on one or more levels, those levels are simply not
changed.
