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 disconnecting the connectors: Attach Fiber-Optic Repair Set - Connector Protective CapsVAS6223/9.

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.

Repairing fiber-optic cables. Refer to FIBER-OPTIC CABLES, REPAIRING .
