摘要：
A multiplex bus system comprises a master control unit (MCU) connected to at least one receiver-transmit unit (RTU) by a data bus. The MCU transmits to the RTU a message comprising a synchronization pulse of known duration and successive time spaced timing signals separated by time duration T marking the boundaries of data bits to be transmitted from the RTU to the MCU. The RTU includes a clock pulse source which utilizes the synchronization pulse to determine the frequency of the clock pulse source in P pulses per duration T. The value P is used in conjunction with the timing signals to create properly timed data determining signals in the data bits.
