摘要

An elevator control system wherein signals between fixtures and the controller are provided in time-division, half-duplex multiplexing protocol is disclosed. Remote stations (64, 150) serialize multiple fixture inputs (66-69) and outputs (106-109) and are characterized for response during particular time slots by binary address means (84). A master station (90) serializes multiple controller inputs (102-105) and outputs (93-96) and is responsive for all time slots in either a transmit or receive mode. A portion (82) of the controller (78) provides clocking (76) and dynamic addressing (98) for the system.
