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.
