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 the complete fiber optic cable if possible.

Make sure that the face surfaces of the connectors do not become soiled.

If disconnecting the connectors: Attach the Fiber-Optic Repair Set - Connector Protective Caps -VAS6223/9-.

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