Zusammenfassung: | A data signal (7) of a data transmitting station (A) is output to another data trapsmitting station (B). A data signal (7) from the other station (B) is input to the first-mentioned station (A). Four statuses: transfer progression, transfer completion, reception allowance, and reception completion of each said data signal, are established depending upon signal levels and input/output timings of a single data control signal (8) which is output to the said other station (B) and a single data control signal (9) which is input from that station (B). |
