A novel and useful hitless node insertion mechanism for configuring a new node to be inserted into an Ethernet network. The contact has a soldering portion, and a retaining arm and a resilient arm respectively extending upwardly from the soldering portion. The electronic control unit operates at least one electromagnetic valve to control operating media flow via the operating media distribution system to activate an actuator which opens or closes the valve. Inspection circuitry is provided for inspecting attributes of the data frame. The guide is configured to cooperate with a corresponding guide element of a docking station to communicatively couple the display device to the docking station. Sharing this responsibility among all communication devices in the network allows each device to maintain an low average communication duty cycle.
