Network Design: General:
The MOST network is an optical network where all control modules are connected in a ring.
All messages on the MOST network travel in the same direction from the Infotainment control module (ICM) to the Integrated Audio Module (IAM).
In a fiber optic network, light pulses are transmitted instead of electrical signals. The light pulses are interpreted in the same way as the electrical signals on the CAN.
The MOST network uses the master-slave concept. This means that a master control module, infotainment control module (ICM) has overall control of communication on the MOST network.
The fiber optic cable is made of plastic. Communication is using red light on a wavelength of 650 Nm.
