Abstract
Abstract A data transmission system includes a transmitter, a receiver and a transmission line. The transmitter produces data on the transmission line for a predetermined time, and the receiver reads in repeatedly and consecutively the data during the predetermined time. A predetermined number is set for repeatedly reading-in the data by the receiver. The number is determined by an external condition during a period of time in which the data are produced. The receiver accepts the data only when the data is read without any change for the determined number of times.

Claim 1
Independent Claim
177 words
A system for transmitting data between a transmitter and a receiver through a transmission line, comprising: a transmitter on one end of the transmission line producing data to be transmitted on the transmission line from the transmitter for a predetermined time; a control output device connected to the transmitter which outputs a number whose value depends on the state of operation of said control output device during the period of time data are transmitted through the transmission line; and a receiver on another end of the transmission line comprising setting means connected to the control output device for setting a number of times for repeatedly reading in said data by said receiver, said number being the number output by the control output device, reading means for reading in repeatedly and consecutively said data the number of times set by the setting means during the predetermined time in which the data are produced on the transmission line, and accepting means for accepting the data only when the data are read, without any change, for said number of times.
