6 Series 630i (N52K) Coupe
There are 2 wires for each signal. The signal is transmitted positively on one wire, negatively on the other
(inverted). This means that each pair of wires is electrically neutral.
Interference from outside has no effect on the signal transmission: such interference affects both wires equally.
The signal information is thus unaffected. This is because: The control unit processes the difference between
the positive and negative signals. This difference remains unchanged even in the event of interference from
outside.
The LVDS data wire for the television consists of the following wires:
•
2 wires for red
•
2 wires for green
•
2 wires for blue
•
2 earth wires
•
Screening
The synchronised pulses are transmitted on the wire for image signals.
-
RGB wire
The RGB wire has 3 wires for image signals: red-green-blue. The synchronised pulse is transmitted on the wire
for the green signal.
The RGB wire is screened. The screening carries no current.
In addition, the RGB wire has its own earth wire for improved electromagnetic compatibility. The earth wire
conducts current.
-
MOST bus
The MOST bus connects the control units for the vehicle's information and communication systems. These
control units are programmed via the MOST port.
> E83, E85, E86: no MOST bus fitted.
-
K-bus: Body bus
>E83, E85, E86
The K-bus links a series of control units whose functions are in the area of the body and in the information and
communication systems of the vehicle.
