9284 Functional Description

“V”: Connect Levels
The command “V” is used to request that a connection be made. It must be
followed by an output number, a comma, and a comma-separated list of input
numbers, one for each level, up to the number of levels in the router. Fewer
than the number of levels may be specified if desired, and the remaining
levels will be left unchanged.
For example, the command:
**V12,7,8,9!!
says that connections are to be made to output 12: from input 7 on level 1,
input 8 on level 2, and input 9 on level 3.
An input number of 0 means the output connection is to be left unchanged.
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 associated with the “V” command's output to the crosspoint
matrix within the SAME vertical interval.
If the requested connection has an output number that does not exist on one or
more levels, those levels are simply not changed. It is an error to request
connection of an input that doesn't exist on that level, even if the input does
exist on some other level. 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 “V” command. No response is generated if this command is
being used to define a salvo.
