BMW "Professional" / MINI "Boost CD" radio: Gateway

The radio forms the interface for data exchange between the MOST bus and the K-CAN. The two bus systems use different data transmission rates and data formats. In order to communicate with both systems, the data from one bus is converted to a compatible format for the other in the radio.

• System master

  The system master links the individual control units.

• Power master

  The power master initializes the network and switches the buses on and off (wake-up, sleep mode).

• Network master

The network master controls and monitors the MOST bus. Each time the network is started up, the system configurations are detected and compared with a stored specified configuration. If systems do not work correctly, these are reset and separated from the MOST bus. Each error or deviation from the specified configuration is saved in a fault memory for the MOST bus.
