** V5,17,12,0 !!<CR>
indicating that output 5 is now connected to input 17 on level 1, to input 12 on level 2, and
does not exist or is not available on level 3.
To turn off output change reporting, use the command:
**U0!!
The difference between an argument value of 1 versus 2 has to do with the response
generated by the router when it receives a crosspoint connect command (“V”, “W”, “X”,
“Y”, or “Z” command). For example, suppose the router sends the following crosspoint
connect commands in a single command sequence:
** Y1,18 Y8,34 !!
If U1 is in effect, the response to this command will be:
** OK !!<CR>
and then sometime later, perhaps up to several seconds later, the crosspoint change
reports will be sent as separate command sequences for each output:
** Y1,18 !!<CR>
** Y8,34 !!<CR>
On the other hand, if U2 is in effect, the response to the original crosspoint change
command sequence will be:
** Y1,18 Y8,34 OK !!<CR>
and no additional crosspoint change reports will be sent because they already HAVE
been sent. The U2 mode of operation is generally more convenient because it produces
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:
