In a system for transferring binary information between a plurality of transmitters (6) and receivers (5) connected to a common communication line (9, 9'; 17), each transmitter (6) and each receiver (5) are connected to the communication line via a coupling unit (11; 11') of their own. The coupling unit comprises a counting device (12, 13; 12', 13'), and the counting devices of the coupling units pertaining to a group of a transmitter and at least one receiver are adapted, after reception of a constantly unique number of pulses predetermined for that group, to couple the transmitter and the receiver(s) of that group to the communication line for transferring a binary information bit from the transmitter to the receiver(s) of the group. Furthermore, a clock device (10; 11, 11') is coupled to supply pulses to all counting devices for sequentially coupling the different transmitter and receiver groups to said communication line. |
