PURPOSE:To simplify a constitution and facilitate setting operation for a characteristic address by forming an address setting part of an EEPROM, setting its data freely with an optical wireless signal, and forming a terminal equipment case to the agreed size by distributors and forming a transmitting and receiving opening for the optical wireless signal in front of the terminal equipment case. CONSTITUTION:A signal processing circuit 10 writes data on the EEPROM constituting the address setting part 11 and the written data is generated by processing a signal received by an optical signal reception part 12, so that the specific 32-bit data is written. The signal received by the optical signal reception part 12 is the optical wireless signal sent out of a data setter and a response signal such as a reception confirmation signal from the optical transmission part 13 is sent as the optical wireless signal. Further, The transmitting and receiving opening 21 corresponding to a light emitting diode LD and a photodiode PD and an opining 22 corresponding to a light emitting diode for confirmation are formed in the front of the terminal equipment case 20, i.e. a cover 20b. |
