ABSTRACT:
The clock demodulator 25 continually demodulates the clock signal of the control CPU 7 transmitted from the clock modulator 10 of the center S. The terminal control CPU 23 performs processes such as transmission and reception of data with the demodulated clock signal as a reference clock. The time required to synchronize the clocks of the CPUs 7 and 23 is eliminated. Transmission and reception of data is executed quickly as soon as right of transmission is transferred to a terminal.
