Abstract
PURPOSE:To suppress the occurrence of an error due to the difference from data transmission/reception speed, by adding a digital signal to set the transmission speed setting to the transmission enable signal in a proper form in returning the transmission enable signal from the reception side as a response to the transmission request signal from the transmission side. CONSTITUTION:A transmission request signal is transmitted from a communication controller 1 prior to the transmission of data to a data transmitter 2 via a transmission request line 101. The data transmission equipment 2 adds a clock pulse to a transmission enable signal in response to the transmission speed of its own equipment and transmits the result to the communication controller 1 via the transmission enable signal line 102. The communication controller 1 counts the number of clock pulses added to the transmission enable signal within a prescribed time T after the transmission request signal transmission. Then the data is transmitted after the same speed as the reception speed of the data transmission equipment 2 is transmitted to its own equipment as the transmission speed based on the result of counting. Thus, the data transmission speed at the transmission side is set surely to the reception speed at the reception side.
