COMMAND HELP
S Commands: “Help”
There are two primary ways to use the Quadra’s help feature:
• Type HELP to list all Quadra commands.
• Type HELP followed by the command to get command-specific help.
S Example: Type H BRI to get help on the Brightness
function.
S Example: Type H WSR to get help on the Window Source
Rectangle function.

RANGES
Parameter values may be a “range” of values, or a defined set of choices (as
described above in the “Predefined Parameter Values
” section).
Ranges are indicated as:
<value1 ... value2>
S Example: The value of BRIght is a range of
<-500 ... 500>

COMMANDS
Commands such as BAUDrate do not need an explicit address, as Quadra has
only a single serial port. However, other commands can be applied to several
destinations. For example the “brightness” command can apply to all Quadra
inputs or to an individual input — depending upon how the command sequence
is structured.
