Nurse call system for use in e.g. hospital, for communication between patient and medical staff, has communication ports connected with electric wires, and message unit arranged to communicate system with chamber-controller over wires
The system has a chamber-controller (1) provided with two communication ports. A processing unit is utilized for processing transmission information between the communication ports. The communication ports are connected with multiple electric wires. A message unit is arranged to communicate the system with the chamber-controller over the electric wires. A micro-controller is arranged for enabling the communication between the message unit and the chamber-controller on a communication bus. The micro-controller and the chamber-controller are communicated based on an asymmetric protocol.
