5 Series E60 530Li (N52) SAL
The two bus systems use/apply various data transmission rates and data formats. To communicate with all
systems, data for each bus is configured as necessary in the CCC gateway.
•
System master
The system master links the individual control units in the Car Communication Computer (CCC).
•
Power master
The power master initialises the network and switches the MOST bus on and off (wake-up, sleep mode).
•
Network master
The network master controls and monitors the MOST bus. Each time the network is started, the exact
system configuration is recorded and compared with a stored target configuration. If systems do not work
correctly, these are reset and separated from the MOST bus. Any operating fault in the network or any
deviation from the target configuration is stored in a fault memory for the MOST bus.
CCC user interface
The CCC user interface control unit contains the operating system for controlling the CCC. Signals from the
controller for selecting the menus and submenus are processed in the CCC user interface control unit. To
actuate the CID, the red-green-blue signals from the graphics processor are converted into Low Voltage
Differential Signalling (LVDS) digital signals.
CCC audio system controller
•
Audio master
The audio master collects all the audio signals in the vehicle, processes the audio signals and outputs them
over the loudspeakers. The audio master also produces additional audible signals for warnings and for Park
Distance Control (PDC). By mixing or fading in and out, a "softer" audible change is obtained between the
signal sources.
•
Connection master
The connection master distributes the signals of the audio sources and the audible signals to the
loudspeakers. The signals are transmitted to the loudspeakers in the following way:
-
Front left and right (acoustic signals, telephone, messages from the navigation system, traffic
information announcements)
-
Front left and right, rear left and right (PDC signals)
-
All loudspeakers (all sources in the "Entertainment" menu)
