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.
The front surface of the connectors must not be contaminated.
If disconnecting the connectors: Attach the :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.
