Tasks
Receive signals Processing signals Transmitting signals
Receive signals
- Media Oriented System Transport (MOST)
- Direct lines
Media Oriented System Transport (MOST)
The tuner unit is a MOST participant and it communicates over this with the head unit (A26/17).
Direct lines
The tuner unit receives the following signals via direct lines:
- Power supply via circuit 31 and circuit 30g
- Electronic wake-up signal for MOST
- SDAR antenna (A2/82) for SDARS (Satellite Digital Audio Radio Service) signals (with code 536 (SIRIUS satellite radio))
- FM 2 and DAB band III antenna amplifier (A2/19), for DAB band III signals (with CODE 537 (Digital radio (DAB)))
- DAB band III antenna amplifier (A2/108), for DAB band III signals (with CODE 537 (Digital radio (DAB)))
Processing signals
With CODE 536 (SIRIUS satellite radio) the tuner unit decodes and amplifies the satellite signals (Time For Division Multiplex (TDM)) and the terrestrial signals (Coded Orthogonal Frequency Division Multiplex (COFDM)) into PCM signals (Pulse Code Modulation).
With CODE 537 (Digital radio (DAB)), the tuner unit decodes the DAB band III signals into PCM signals.
Transmitting signals
- MOST
- Direct lines
MOST
The tuner unit is a MOST participant and it communicates over this with the head unit. The audio signals are sent to the sound system amplifier control unit (N40/3) (with CODE 810 (Sound system)), to the advanced sound system amplifier control unit (N40/7) (with CODE 811 (Advanced sound system)) or to the head unit (except CODE 810 (Sound system) and except CODE 811 (Advanced sound system)).
Direct lines
The tuner unit sends the following signals over a direct line:
- Supply voltage through signal line to FM 2 and DAB band III antenna amplifier (with CODE 537 (Digital radio (DAB)))
- Supply voltage through signal line to DAB band III antenna amplifier (with CODE 537 (Digital radio (DAB)))
