A system (1) comprises at least one organization device (2, 3) for arranging a multiplicity of medical devices (20, 30) and for providing a communication link for the multiplicity of medical devices (20, 30). A multiplicity of medical devices (20, 30) is arranged on the at least one organization device (2, 3), each medical device (20, 30) comprising a display (200) for displaying operational information of the medical device (20, 30). A control device (7) is communicatively connected with the at least one organization device (2, 3) and the multiplicity of medical devices (20, 30) arranged on the at least one organization device (2, 3), wherein the control device (7) comprises an input device (70) for allowing to select by a user at least one of the multiplicity of medical devices (20, 30) for inputting a control command for controlling the at least one selected medical device (20, 30). Herein, the control device (7) is constituted to generate and transmit, upon selection of at least one of the multiplicity of medical devices (20, 30) via the input device (70) of the control device (7), at least one control signal (S) for causing a visual signal (V) to appear at the selected at least one medical device (20A, 20B) and/or at the other, non-selected medical devices of the multiplicity of medical devices (20, 30) to visually differentiate the selected at least one medical device (20A, 20B) from the other, non-selected medical devices.
