摘要：PROBLEM TO BE SOLVED: To reduce time losses for transmitting and receiving data information by the transmission time of omitted beacon information by not transmitting beacon information at the transmission timing of beacon information during data transmission. SOLUTION: When a time out of a beacon timer is detected in a state without transmission data, a radio transmission frame of beacon information is radio-transmitted to respective radio slave stations 4a, 4b, 4c and 4d in the same radio zones Z1 and Z2 through a radio part. In such a case, it is recognized that a radio wave is not emitted to a present communication frequency band before the frame is transmitted. Then, the communication frequency is switched to a next frequency, in accordance with a hopping pattern which is set in a storage part. Beacon information which is radio-transmitted from radio master stations 2a and 2b at each beacon time out is not transmitted, when the beacon timer is timed out during the transmission of data information. In this way, communication efficiency of a data information cable enhanced.
