  • Bus competitive control apparatus
    Patent number: 5452422
    Abstract: When a delay of communication data due to a common data circuit obstructs a collision detection between units, a transmission rate control section produces a speed setting basic clock, whose period Tm is set to be long, on the basis of the output of a sequence control section. A transmission section and a reception section comprising a demodulator are controlled on the basis of the clock so as to set the transmission speed of a collision detection field to be low, thereby reducing the influence of the delay on the communication data.
