Serial Interface Commands & Responses Protocol
Sonifex SCi remote control software handles all communication with the Reference
Monitors via a convenient graphical user interface. However, this protocol is provided for
those users who wish to develop their own remote control applications or communicate
with the Reference Monitors using a text-based terminal program.
For more information on how to install and operate the SCi software, please see page 54.
Serial Data Format
Connection is 19200,e,8,1 with XON/XOFF ow control.
Commands are case-insensitive and all parameters are in hex.
Commands should be terminated in a carriage return character, a line feed character may
be sent but it will be ignored.
Further commands sent before the rst command is acknowledged will be ignored.
Responses will be CR & LF terminated.
After power up a welcome string is sent – “Initialising Sonifex Reference Monitor…done”
