Instruction set AudioControl 12.8
The AudioControl 12.8 can be controlled using RS232 strings sent by other units, such as home
automation systems for example.
RS232/A front panel port settings are 19200 bits per second, 8 data bits, no parity, 1 stop bit and no
flow control. RS232/A port settings are fixed. RS232/B and C rear panel ports can be configured via
serial commands or the Graphic installer interface program.
Standard ASCII strings are used to control the AudioControl 12.8 so it is possible to use Terminal
software (e.g. HyperTerminal, Hercules, ...) to test, configure and/or control it. Instructions are not
case sensitive. Each string must be ended with a Carriage Return (<CR>, ASCII code 13 or ”\n”).
Alternatively, if you like to look up the syntax of the possible strings and AudioControl 12.8 answers
sent via RS232, open the program’s log window while operating the unit via the program.
The string is structured in the following order:
Command Attribute Parameter1 Value
<CR>
Strings require a space between each parameter; the last character in the string needs to be a
carriage return <CR>. Line feed <LF> characters are ignored so they may be used.
An instruction consists of a command, an attribute and possible one or more parameters. E.g. the
instruction to switch the music volume from zone 1 at maximum level will look like this:
SET MSCLVL ZONE1 12<CR>
where SET is the command, MSCLVL the attribute, ZONE1 the first parameter and 12 the second
parameter which is the maximum value in this case.
