AVC-LAN Circuit (Radio and Navigation Assy-Disc Player Changer)

AVC-LAN CIRCUIT (RADIO AND NAVIGATION ASSY - DISC PLAYER CHANGER)

CIRCUIT DESCRIPTION

Each unit of the radio and navigation system connected to the AVC-LAN
(communication bus) communicates by transferring the signals from each switch.

When a short to+B or short to ground occurs in this AVC-LAN, the radio and navigation assy system will not function normally as communication is discontinued.

In the AVC-LAN, the radio and navigation assy becomes the communication master and has enough resistance necessary for communication.
