Notes on MOST bus

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

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

Replace complete fiber optic cable if possible.

The front surface of the connectors must not be dirty.

If the connectors are disconnected: attach Protective cap for cable connector (VAS 6223/9).

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