In all MOST control units, at least one sending diode and one receiver diode are installed. The sending diode of a MOST device is connected to a receiver diode of a 2nd MOST device. This results in a ring where the light signal is reinforced in each control unit (in each control unit, the light signal is transformed into an electrical signal).







The graphic clarifies the cabling of the individual MOST control units which vary according to their equipment.
