Abstract: This paper introduces a kind of audio control network based on CAN and implements the interface between the communication bus and the system’s modules. It also brings forward communication protocol for audio effect control. The audio controller takes full advantage of the characteristic of the CAN bus. So the various modules can be configured neatly and expanded easily. The technique promotes the state of the audio device’s network control performance, which is of great significance in the instrument with RS232 interface.

Key words: CAN bus, Audio control network, Communication protocol
