AVC-LAN Circuit (Multi-Display Assy - Radio Receiver Assy)

AVC LAN CIRCUIT (MULTI-DISPLAY ASSY - RADIO RECEIVER ASSY)

CIRCUIT DESCRIPTION
Each unit of audio system connected to the AVC LAN (communication bus) transfers the signal of each switch by communication.
When +B short and GND short occur in this AVC LAN, audio system will not function normally as communication is discontinued.
In this AVC LAN, the radio receiver assy becomes the master of the communication, and the radio receiver assy has resistance necessary for transmitting the communication.
