B2128 UART COMMUNICATION LINE
B2128 UART COMMUNICATION LINE
DescriptionINFOID:0000000006248348
Driver seat control unit performs UART communication with the automatic drive positioner control unit using 1
communication lines. Driver seat control unit receives t he operation signals of tilt & telescopic switch, door mir-
ror remote control switch, and the position signals of door mirror sensor from the automatic drive positioner
control unit and transmits the operation request signal.

Part name Description
AV control unit  Integrates hard disk drive (HDD) allowing map data and music data to be stored.
 It is the master unit of the MULTI AV system, and it is connected to each control
unit by communication. It operates each system according to communication sig-
nals from the AV control unit.
 The AV control unit includes the audio, hands-free phone, navigation, USB con- nection, DVD play and vehicle information functions.
 It is connected to ECM and combination meter via CAN communication to obtain
necessary information for the vehicle information function.
 It inputs the illumination signals that are required for the front display dimming con- trol.
 It inputs the signals for driving status recognition (vehicle speed, reverse and park- ing brake).
 The RGB digital image signal and composite image signal are output to front dis-
play unit.
 Switches image and sound output to video distributor, inputting image switch sig- nal from headrest display unit via AV communication.
 Amp. ON signal and mode change signal transmitted to BOSE amp.
 Update of map data is performed with the DVD-ROM.
Front display unit  Front display image is controlled by the serial communication from AV control unit.
 RGB digital image signal is input from AV control unit.
 Composite image signal is input from AV control unit.
 Camera image signal is input from around view monitor control unit.
 Touch panel function can be operated for each system by touching a display di-
rectly.
Headrest display unit  Composite image signal [USB (video data), DVD and auxiliary input images] is in-
put from the video distributor.
 It receives the DVD/AUX/USB sound signal from the video distributor, and then transmits it to the headphones.
 Outputs image switch signal to video distributor via hard wire, according to rear seat remote controller operation.
 Outputs image switch signal to AV control unit via AV communication, according to
rear seat remote controller operation.
