INFRARED RAY COMMUNICATION ACCESS POINT DEVICE

摘要

PROBLEM TO BE SOLVED: To automatically select any of a plurality of infrared ray ports (infra red ray transmission reception means). SOLUTION: The infrared ray communication device that has a plurality of physical infrared ray ports (infrared ray transmission and reception means) acting practically like a single infrared ray port is provided with a plurality of infrared ray transmission and reception means An, a signal strength detection means B that detects a most effective infrared ray level from a plurality of the infrared ray transmission and reception means, a changeover means C that selects a valid means among a plurality of the infrared ray transmission and reception means according to a signal from the signal strength detection means, a protocol processing means D that conducts prescribed infrared ray data communication with other devices, a bridge means E that conducts processing such as absorption of the difference between the transmission rate of the infrared ray system and that of a wired system, and that of a wired system interface means F that receives/outputs a signal of the wired system.
