The Audio switcher is high performance intelligent matrix switch equipment which is specially designed for the broadcasting of the audio signal. It is widely used in speech engineering, audio-visual teaching, and command and control center, multi-media conference room and so on and used for switching audio signal. Most of the existing audio switcher support serial control protocol and it can be controlled by the third party software. In this paper, a directive programmable audio switcher intelligent control system was realized. Any kind of audio switcher which supports serial communication protocol can be controlled by this system without any software changing. The only thing to be needed is to change the programmable command list.
