When several units or several devices are connected to a bus, it can happen that at least two units or devices want to transmit and access the bus simultaneously. To avoid such competitive situations, it is generally known to insert a control circuit in a bus, to control and ensure the transmission of the information. The problem is solved for the remote control technique by providing two organization lines for the control, one of which is connected as a request line to the units or devices and the second serves as a stop line, to stop an address counter during the time a unit or a device outputs data, see DE 33 43 456 C2. The known solutions have in common that the information sink, which is connected to the bus or to the line through at least one additional control line, controls the information source's mode of operation in such a way, that only one information source is placed in the transmission condition during a predetermined period of time.
