PURPOSE:To eliminate the need for a program for the generating processing of an error detection code or an error correction code by storing in advance a prescribed detection code or error correction code corresponding to a self identification code into a read only memory together with the self identification code in advance. CONSTITUTION:In the case of setting an ID code in the manufacture process of a factory, the switch 10 of a master set 1 is turned on, the mode is set in the ID code write mode, an ID code generator 12 is connected to a connector 11 to set the ID code and a BCH code corresponding to the ID code is supplied to a control circuit 6, the ID code and the BCH code corresponding to the ID code are written in an E<2>PROM 8 based on the ID code write program of a program memory 7 in the control circuit 6. On the other hand, the ID code generator 12 writes the ID code and the BCH code corresponding to the ID code the same as the ID code and the BCH code corresponding to the ID code of the master set 1 to a ROM 21, which is mounted on a slave set 2. |
