ABSTRACT OF THE DISCLOSURE A circuit arrangement is provided for serial data transmission between a plurality of subscriber stations via a data bus, the circuit arrangement comprising data transmitters that are in a high-impedance state in the passive condition and in a low-impedance state in the active condition. In such a circuit arrangement, a mutual control of the subscriber stations occurs by way of the data bus without the assistance of additional control lines. This is achieved with the assistance of a recognition circuit having two data receivers in fail safe circuitry connected in an antiparallel manner at their inputs and having their outputs connected to a logic element. The control arrangement is particularly suited for utilization in remote control devices.
