9284 Functional Description

If “U2” is in effect (see “U” command), the response will include one or more
V, Y, or X commands to report the new status of the output. The response will
be the same as if an “O” command were issued for the output immediately
following the “X” command. No response is generated if this command is
being used to define a salvo.
“Y”: Connect AFV
The command “Y” is used to request that a connection be made. It must be
followed by an output number, a comma, and an input number. The
connection is made on all levels (AFV).
For example, the command:
**Y2,29!!
says that input 29 is to be connected to output 2 on all levels.
An input number of 0 means the output connection is to be left unchanged,
not very useful in a “Y” 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.
Unless otherwise noted in the documentation for a specific switcher, it can be
assumed that the switcher software guarantees to send all level changes for
the “Y” command's output to the crosspoint matrix within the SAME vertical
interval.
Any input or output number may be specified as long as it exists on at least
one level. 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.
If “U2” is in effect (see “U” command), the response will include one or more
V, Y, or X commands to report the new status of the output. The response will
be the same as if an “O” command were issued for the output immediately
following the “Y” command. No response is generated if this command is
being used to define a salvo.
