Media Oriented System Transport (MOST) data bus system
The digital components of the COMAND operating, display and controller unit (A40/3) are networked with each other by the MOST (Media Oriented
System Transport). The databus system is used to transmit data (control commands and useful information) between the various system components. In
the process both control data and the actual audio signals (music from CD changer (A2/6), voice when making a telephone call) are transmitted. Because
some of the individual components work with different data formats or require different data transfer rates and security levels, different data bus systems
have been installed.
Data bus systems:
^
Media Oriented System Transport (MOST)
^
Controller area network bus class B (interior compartment) (CAN B)
^
Controller Area Network bus, class C (engine compartment) (CAN C)
Data and signals between the audio gateway control unit (N93/1), the COMAND operating, display and controller unit (A40/3), the CD changer (A2/6),
the E-call control unit (N112) and the hands-free system control unit (A35/1) are exchanged via the MOST (Media Oriented System Transport).
In the process both control data and the actual audio signals (music from CD changer (A2/6), voice when making a telephone call) are transmitted. The
COMAND operating, display and controller unit (A40/3) communicates with the audio gateway control unit (N93/1) and the other system components
via the integrated Media Oriented System Transport (MOST) interface.
Interfaces
The data exchange with the instrument cluster (A1) takes place via the Controller Area Network bus class B (interior) (CAN-B). This is how the
instrument cluster (A1) receives the audio, telephone, and navigation data for the multifunction display (A1p13) in the instrument cluster (A1) and the
time from the COMAND operating, display and controller unit (A40/3) via the audio gateway control unit (N93/1).
The portable CTEL (A34/6) is not on the Media Oriented System Transport (MOST), but is directly connected to the COMAND operating, display and
controller unit (A40/3).
