* For systems where all of the audio channels are not switched on the same level (e.g., an audio only
Optima that routes 8 channels of audio on Level 1 and 16 channels on Level 2), volume and input gain
commands for each of the levels must be entered separately.
Note: Groups of signals (e.g., RGBHV plus stereo) and breakaways of signals (e.g., RGBHV only or
stereo only) are stored in the configuration definition as virtual matrices (VMs). While some methods
of control (e.g., control panels) use the term "VM", BCS commands on a serial controller use the
equivalent term "level" designated by an "L". For the purposes of this document, the terms virtual
matrix and level are interchangeable.

Command strings typically are not case-sensitive (for exceptions – see "Heritage Systems"
on page 37).
All command strings must end with the Take command "T" which tells the system to execute
the command.
O
" " is the letter O, not the number zero (0)
Entering "X" at any point in a command string cancels the command.
A command cannot be canceled after the "T" has been entered.
Command strings cannot be edited. If a mistake has been made, enter an "X" and then reenter
the command.
To specify multiple outputs, inputs, levels, or local presets, enter a space " " between each
number. Multiple inputs are only valid in Disconnect commands.
To specify a range of outputs, inputs, or local presets, insert a colon ":" between the lowest
and highest numbers of the range (not supported if the command is otherwise invalid,
e.g., cannot specify a range of inputs in a Change command; the first input only would be
routed.).
Colons ":" and spaces " " can be used in the same command string.
If the level designation "L" is omitted, the command is executed on the default level, which is
normally Level 0.
