    3. The master unit of the MOST network is the multi-media module receiver assembly.

    4. MOST communication lines connect each slave unit centering around the master unit to form a MOST network ring.

    5. The master unit sends a wake-up signal to activate each slave unit connected to the MOST communication line.

      HINT:
      If a short or open circuit occurs in the MOST circuit, communication will be interrupted and the system will not operate normally.
