more immediate feedback to the controlling device that is sending a crosspoint change
command. The U1 mode of operation is provided for compatibility with older control
systems.
“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 ë-ë (dash) means the output is to be
disconnected
. If the router does
not support disconnected outputs, the output connection will be left unchanged.
“W”: Connect Outputs
The command "
W
" is used to request that a connection be made. It must be followed by
a level number, a comma, and a comma-separated list of input numbers, one for each
output, up to the number of outputs in the router. Fewer than the number of outputs may
be specified if desired, and the remaining outputs will be left unchanged.
For example, the command:
**W1,17,3,9!!
says that connections are to be made on level 1: from input 17 to output 1, input 3 to
output 2, and input 9 to output 3.
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:
**W0,8,3,7!!
says that connections are to be made on all levels: from input 8 to output 1, input 3 to
output 2, and input 7 to output 3.
An input number of 0 means the output connection is to be left
unchanged
.
An input number of ë-ë (dash) means the output is to be
disconnected
. If the router does
not support disconnected outputs, the output connection will be left unchanged.
It is an error to request connection of an input or output that doesn’t exist on the specified
level, even if the input or output does exist on some other level. However, if the level
number is “0”, any input or output may be used 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 and 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 outputs. The response will be the same as if
“O” commands were issued for the outputs immediately following the “W” command. No
response is generated if this command is being used to define a salvo.
“X”: Connect Crosspoint
Use command X 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:
