ABSTRACT:
A bus connection switch is connected in series at some point on a bus that transmits control data. The bus connection switch releases the bus at the position of the switch when being opened, or connects the bus when being closed. The bus is led from both sides of the bus connection switch to an extension connector. If an extension unit having a bus connection switch in a closed state is connected to the extension connector, the bus is connected via the extension unit. A detecting circuit comprised by an extension port opens the bus connection switch comprised by the extension port if detecting that an extension unit is connected to the extension connector comprised by the extension port, or closes the bus connection switch comprised by the extension port if detecting that an extension unit is not connected.
