Notes on MOST bus
Apart from the CAN bus, the optical data bus “MOST bus” is used.
Optical fibre conductors are used as “connecting cables”. For protection purposes, optical fibre conductors are run through corrugated pipes.
As far as possible, renew the complete optical fibre conductor.
Make sure that the cross-cut ends of connectors are not dirty.
   
If connectors are separated, attach protective cap for cable-set connector -VAS 6223/9-.
When routing the optical fibre conductor, make sure that the minimum bending radius of 25 mm is observed. Optical fibre conductors must not be kinked or pinched.
