Abstract

PURPOSE:To eliminate a useless cycle, by transmitting a single pulse having a comparatively long duration prior to a transmission of a clock pulse from a data collecting station to a terminal device and then applying a resetting at the side of the terminal device. CONSTITUTION:A single pulse P1 having a comparatively long duration T1 is transmitted prior to a transmission of a clock pulse P2. Actually the output signal of a delaying circuit 20 becomes as shown in the figure (b) when a pulse sigal as shown in the figure (a) is supplied to the terminal device II from the data collecting station I. Then a counter divider 21 and a counter 22 are reset with a delay of time t1 to a rise of the pulse signal P1, and the output signal of a delaying circuit 25 becomes as shown in the figure (c). The gate circuit G is opened with a delay of time t2(t2>t1) to the rise of the signal P1. In such a way, the device II is put under a queuing state by the signal P1 transmitted from the station I.
