Abstract
A RF communication system includes a RF communication module capable of controlling either an IR communication system-controlled device or a controlled device not equipped with a reception circuit for receiving IR signals remotely with RF signals. The RF communication module is equipped with an antenna for receiving RF signals, a RF communication circuit for demodulating the remote control data from the RF signal received by the antenna, a UART interface for outputting bit stream remote data to a device-side microcomputer of the controlled device, and a communication control unit having two types of communication interfaces in a pulse signal interface that outputs a pulse modulated signal, having been pulse modulated with remote control data, to a pulse modulated signal input port of the device-side microcomputer, so that remote control data transmitted by RF signals is output freely, as either bit stream or pulse modulated signals, to a device-side microcomputer of the controlled device.
