Abstract
An elevator system in which an elevator car serves the floors of a building under the direction of a car controller. A hall lantern controller and associated hall lamps are located at each floor served by the elevator car. A serial hall lantern riser extends from the car controller past each floor served by the elevator car, with each hall lantern controller being connected to the serial riser. The car controller prepares serial messages for the riser, with each including a command for an identified hall lantern controller. Each hall lantern controller recognizes its own messages, it responds to the associated command, and it sends a serial acknowledgment signal back to the car controller.
