An electrosurgical system comprising: a plurality of electrosurgical connection units, each electrosurgical connection unit comprising an input port connectable to an electrosurgical channel and an output port connectable to an electrosurgical instrument, the electrosurgical connection unit configured to connect the input port to the output port; an electrosurgical network comprising a plurality of electrosurgical links that connect the input ports of the electrosurgical connection units to an electrosurgical channel; and a control unit configured to: receive information from a device indicating that the device has detected an electrosurgical generator connected to the electrosurgical channel, the device being one of the electrosurgical connection units and an electrosurgical output device connected to the electrosurgical channel; determine a location of the electrosurgical generator in the electrosurgical network based on the received information; and transmit one or more control signals to the electrosurgical connection units and/or one or more electrosurgical output devices connected to the electrosurgical channel to cause the output port of a selected combination of electrosurgical connection units to be connected to the electrosurgical channel based on the determined location of the electrosurgical generator.
