PURPOSE:To shorten the overall data length to increase the number of frames transmitted within a certain time by synthesis processing of an ID code and a channel ID. CONSTITUTION:The connecting operation is performed by a master machine 1 or a slave machine 2, and IC code collation and CB-ID collation for prevention of erroneous connection of adjacent channels are performed through a connected control channel. The ID code and the CH-ID to be added are subjected to XOR operation by an encoding part 3 to generate a synthesized code of the ID code and the CH-ID by the synthesis processing, for example, by the master machine 1 on the sending side. This synthesized code is transmitted as control data of frame constitution from a transmission part 6. The slave machine 2 on the reception side receives the synthesized code by a reception part 13 and decodes it and CH-ID data of a reception channel number by XOR operation in a decoding part 11 and performs separation and extraction processings of the ID code. It is discriminated whether the extraction result coincides with the ID code of the slave machine itself or not by a CPU 9. |
