COMMUNICATION SYSTEM

1. Components in the audio system communicate with each other through the Audio Visual Communication-Local Area Network (AVC-LAN).

2. The receiver has a resistance of 60 to 80 Ω, which is necessary for communication.

3. When a short circuit or circuit breakdown occurs in the AVC-LAN circuit, the audio system does not operate normally due to the communication cutoff.

DIAGNOSIS FUNCTION

1. The audio system has a diagnosis function. The diagnosis result is displayed on the LCD of the radio receiver.

2. A components code (physical address), or 3 digit code (in hexadecimals), is set for each component of the AVC-LAN.

3. A logical address, or 2 digit code (in hexadecimals), is set for each function and component unit in each component of the AVC-LAN.
