RS232 commands
EXT VOL potmeter connection, use a standard shielded audio cable:
Exit the main menu and save all parameters that have been changed.
IMPORTANT:
Some parameters will not be saved when exiting without saving:
All audio related parameters are stored in a temporary memory location and will be lost when
cycling power. In order to save them, you need to select SAVE AND EXIT.
LEVELS, MAX LEVELS, EQ settings, CROSS-OVER settings, including the PHASE setting of the
subwoofer channel, AUTO LD setting and DELAY settings must be saved prior to exiting the main
menu. All system related parameters, such as display contrast etc, are automatically saved.
Via RS232 even more features are available, with the exception of the password protection which
is accessible ONLY via the front panel controls.
For example, it is possible to edit the standard text appearing on the display using RS232
commands. On the following pages, we will explain the possibilities of remote control via RS232.
In case you might experience RS232 communication problems, consult an experienced system
engineer to get you started.
Port settings are fixed at 19200 baudrate, 8 databits, no parity, no handshake. LF (line feed), BS
(backspace) and ECHO parameters are not enabled by default. They can be enabled using an
RS232 command string. We strongly advise not to change any RS232 communication related
parameters.
Instructions are not case sensitive. Each command must end with “<CR>”. When the instruction
has been executed, the unit will send a reply, provided that a parameter or setting has been
changed.
If the parameter value is already equal to the value specified in the instruction, no parameter
will be changed so the unit will not reply! The reason is obvious: only changes are reported. It is
possible to retrieve a value by using the GET command. E.g. GET MASTER.
Exit the main menu and return to the main screen without saving. Please note that some
parameters, such as system settings will automatically be saved.
