Abstract
To control an information processing system in which a host unit is connected by radio communication to a slave unit, the host unit transmits data and carrier waves both containing ID information selecting a specific information process, and the slave unit recognizes the ID information, thus performing its operation accordingly. A difference in frequencies of the carrier waves is regarded as a type of ID information. The slave unit identifies a frequency, receives data corresponding to the frequency, and performs the specific information process on the basis of the data received at this frequency. The information processing system, especially that composed of a slave unit and host units, thus constructed and controlled is capable of operating efficiently, without wasting electricity.
