Serial Remote Control (RS232)
The MA-2 is equipped with a 9-pin RS232 port for system remote control via a serial cable
(not provided by Meitner Audio). Please use a standard RS232 cable. Do not use a null
model cable, as this will not work. RS232 communication port settings:
• 19,200 baud
• 8 bits
• 1 stop bit
• no flow control
• no parity bit
Commands to the MA-2
All commands sent to the MA-2 consist of 3 ASCII characters (all lowercase) followed by a
carraige return or <CR>. Repeating a <CR> will repeat the last command sent. Received
commands are not stored in a stack. They need to be sent in intervals of at least 50ms to
allow enough time for the MA-2 to execute a command before receiving the next one.
