Abstract

A medical supply unit includes a bus system for transmitting instructions of control elements to actuators. The bus system is provided with transmitters and receivers being connected to each other by a transmission system. Via the transmission system, commands of the transmitters are transmitted, which are controlled by the control elements, and the responsive receiver transfers the command to a switching instruction at an output of the responsive receiver so as to control an actuator.

7. The medical supply unit of claim 1, wherein the transmitter further comprises an input keyboard.

8. The medical supply unit of claim 7, wherein the bus system is further configured, by a configuration software, to associate the first and second outputs with different keys of the input keyboard.

9. The medical supply unit of claim 1, wherein the transmitter is a first transmitter, the bus system further comprising a second transmitter, and wherein the receiver is configured to receive respective commands from the first and second transmitters.

10. The medical supply unit of claim 1, wherein the receiver is a first receiver, and the bus system further comprises a second receiver, and wherein the second receiver is configured to receive the at least one command from the transmitter and to transmit the at least one command associated with the second receiver to the switching instruction at an output of the second receiver.

11. The medical supply unit of claim 1, wherein the transmitter further comprises an analog switch configured to connect the transmitter to the transmission system, and wherein the at least one command is transmitted to the transmission system only when the analog switch is closed.

12. The medical supply unit of claim 1, wherein the transmitter is further configured to periodically transmit the at least one command, and wherein the receiver is further configured to deactivate the receiver output after lapse of a predetermined time, when the at least one command associated with the receiver is not received.

13. The medical supply unit of claim 1, wherein the first and second receiving units further comprise a matching hardware.

14. The medical supply unit of claim 1, wherein the receiver output is coupled to an operating element of the brake or of the lifting motor.

15. The medical supply unit of claim 1, wherein the bus system is a first bus system, the medical supply unit further comprising:

a second bus system, the first and second bus systems each having a local and a global address area; and
