911 Carrera 4 Coupe (996) F6-3.6L (2002)
The external amplifier (Harman or BOSE) is available as an optional feature and is linked to the PCM2 via the optical waveguide.
Function Of The Components
Gateway
Gateway
The gateway is integrated in the PCM2. Together with the MMI, it is a fixed component of each PCM2. It provides a connection to CAN comfort via its
nodes. Diagnostic and useful data is exchanged with the CAN via these nodes. It creates links to the following systems:
-
CAN comfort
-
Media Oriented Systems Transport (MOST), internal (electrical)
-
Voice control system (VOCS) (optional/insertion)
-
Navigation (optional/insertion)
-
Man Machine Interface (MMI)
-
Single CD
-
Media Oriented Systems Transport (MOST), external bus (optical)
Internal Amplifier
Internal Amplifier
The internal amplifier is part of the PCM2 (installed on the main board).
Man Machine Interface (MMI)
Man Machine Interface (MMI)
The MMI is part of the PCM2 (on the main board), It carries out the diagnostics of the ring break diagnosis line (stub cable) and the diagnostics of the
optical distribution line.
MOST - Optical/Electrical
