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 "X" command. No response is
generated if this command is being used to define a salvo.
"Y": Connect AFV

(None or V/Y/X command, depending on
which "U" command argument is in effect,
see "U" command description.)
Optional status response.
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.
