If the first field is not a known command (as listed above) or SW field is different from the serial address programmed in the switch
memory, the command will be ignored. If the SW field corresponds to the serial address, but the syntax is wrong after this field,
the switch will answer with a bad response ?
Set Volume Level For Output/User Port (for command string AV SW,OP,VV in chart on page 11)
This command will set the volume of the specified AUDIO output/user port from a scale of 00 to 99, which represents a logarithmic

Autostatus
When Autostatus is enabled, any output-to-input connection change in the VEEMUX-A will cause an Autostatus message to be
sent via RS232 to the administrator. The format of the message would be "pc SW,OP:IP
Example of an Autostatus message:
pc 01,01:04
which means "At the switch with unit address 01, the output (01) has changed connection to input 04."
Notes: Message to the administrator will be delayed by any RS232 traffic being received by the switch from the
administrator.
Autostatus must be disabled before using SerTest or the Matrix Switcher's Control Program (page 13).
By default, Autostatus is disabled and must be manually enabled. Autostatus is also disabled any time the power to the
VEEMUX-A is interrupted.
