On vehicle models from the E65 on,
BMW is for the first time using fibre-
optic cables as standard for
communication between control units.
The optical buses are notable for their
high data transmission rate and they
are not susceptible to electromagnetic
interference. The optical buses in
question are the MOST bus, primarily
used for in-car entertainment
electronics, and the byteflight bus,
which serves predominantly
safety-critical functions.
OPPS has been designed for
encoding, individualising and
programming ( CIP) via the
Software Service Station (SSS)
and envisaged for use as part of
the BMW diagnostic system (DIS)
from DISPlus and Group Tester
One (GT1). It is intended for
testing and programming tasks
from the E65 series, taking the
place of the diagnostic head.
Originally made 16/20pin adapter
OPS is intended for rapid programming of control units.When operated
at the SSS, no diagnostic or technical measuring pro-cedures are
