1. A patient support apparatus adapter for processing communication between a patient support apparatus and a nurse call system wall outlet, the nurse call system wall outlet being coupled to a nurse call system, the adapter comprising:

  • a receiver adapted to receive communication signals from the patient support apparatus;

    an interface adapted to receive a multi-pin connector that electrically communicates with a cable coupled to the nurse call system wall outlet, the interface including a plurality of electrical leads, each lead of the plurality of electrical leads being electrically coupled to a particular pin of the multi-pin connector when the multi-pin connector is received by the interface;

    a plurality of switches, each of the plurality of switches electrically coupled to a corresponding pair of the plurality of electrical leads;

    a memory storing mapping data indicating how the communication signals received from the patient support apparatus are to be mapped to the plurality of electrical leads, as well as whether each of the plurality of switches should be in a normally open state or a normally closed state;

    configuration circuitry adapted to map the communication signals received from the patient support apparatus to the plurality of electrical leads in accordance with the mapping data, the configuration circuitry further adapted to set each of the plurality of switches to the normally open state or the normally closed state in accordance with the mapping data; and

    a controller adapted to store the mapping data in the memory upon receipt of a message from an off-board source, the controller further adapted to change a state of at least one of the plurality of switches from the normally open state to a closed state, or from the normally closed state to an open state, based upon the communication signals from the patient support apparatus.
