The subwoofer can be controlled via the RS232 port on the
amplifier panel. The subwoofer can be controlled by sending a
string of characters to the RS232 connector.

CommandProtocol

Each string of commands sent to the Subwoofer must follow the
same structural protocol. These commands are detailed in the
Command List opposite. To control the Subwoofer using RS232
commands, specific strings of characters (forming a command
string) must be sent via a RS232 terminal. Each command
string should be terminated by both:
<CR> (the ASCII carriage return character, 13 decimal)
<LF> (the ASCII line feed character, 10 decimal)
These are generally found in the RS232 terminal settings.
The Subwoofer replies to a valid command with the updated
information changed by a SET command, or the information that
was requested by a GET command. If the Subwoofer receives an
invalid command it will reply with ERROR<CR><LF>
Note: any SET command other than SET_O during Standby
is deemed invalid.
