Notes on Bluetooth Technology

A standardized radio connection is used for data transfer between the Information Electronics Control Module 1 -J794- and Cellular Telephone -R54- - Bluetooth Technology.

An additional transmitter/receiver unit is installed in the Information Electronics Control Module 1 -J794-. A Bluetooth Antenna -R152- connects the Information Electronics Control Module 1 -J794- and the Cellular Telephone -R54- so that the Cellular Telephone -R54- can be operated without a wire connection.

The range of the radio connection is approximately 10 m.

Notes on MOST Bus

The optical Data Bus "MOST Bus" is used in addition to the CAN Bus.

A fiber-optic cable is used. Fiber-optic cables are routed inside corrugated tubes for protection.

Replace the complete fiber-optic cable if possible.

The front surface of the connectors must not be contaminated.

If disconnecting the connectors: Attach the Fiber-Optic Repair Set - Connector Protective Caps: VAS 6223/9  .

When routing fiber-optic cables, make sure not to go below the minimum bending radius of 25 mm. Do not crush or kink the fiber-optic cables.
