RS-232 (Serial) Extended Command Set
All valid commands receive a response, and all changes in the AVAtrix system via any method are reported. In the
“Command” column on the next page, actual commands are shown in upper case, and parameters are represented by
lower case bold characters (commands are not case-sensitive). All commands must be surrounded by brackets [ and ].
Command Denitions (Extended)
Command: String received by the AVAtrix from the controlling hardware. Commands are not case sensitive and should
be 8-bit with No parity. The only characters recognized are: letters (a-z and A-Z), numbers (0-9), brackets ([ and ]), signs
(+ and -), and the question mark (?) . All other characters, including spaces and commas, are optional and may be either
included for clarity or omitted entirely.
Response: String transmitted by the AVAtrix to the controlling hardware. Responses are 8-bit with no parity. Responses
are transmitted as noted below, and always have a C/R L/F sequence (0x0d, 0x0a) after each line.
Query: A special command that requests the current status of one or more connections or settings, but does not change
any operation within the AVAtrix. A query must always contain the ? question mark character.
Parameters: Values contained within commands and responses which identify groups, sources, zones, and router
devices.
j: group in range {1-6}
m: source in range {1-6}
n: zone in range {1-6}
x: A/V router device in range {A-F}
In this document, braces { and } are used to signify ONE of the enclosed characters. For example, {L,U} indicate either of
the two characters L or U.

* ExpressRamp™ enables a smooth volume change from the current level to a pre-dened level using a single RS-232
command. It streamlines the programming of audio “scenes” on control systems and avoids abrupt volume changes.
