Control Unit/Control Unit Connection
The MOST ring is composed of optical point-to-point connections between 2 control units. Each control unit has a network interface. The network interface consists of:
MOST Fiber Optic cable
- An opto-electrical converter (optical waveguide receiver, already mentioned).
- An opto-electrical converter (optical waveguide transmitter, already mentioned).
- A MOST transceiver (interface between the optical waveguide receiver/transmitter and the electronic network driver).
- A network driver, the so-called NetServices.
The NetServices run on a microcontroller (main computer in the control unit)
On the application level, a control unit in the MOST framework contains stand-alone function units, so-called function blocks. Examples of function blocks include:
- Tuners
- Amplifiers
- CD players
A control unit can contain several function blocks at one time, e.g. the AVT contains the functions:
- Antenna
- Amplifier
- Tuner
