Connection for external multimedia devices |
| 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. |
