Abstract:
A communication apparatus, comprising:a transmitter for transmitting a transmission code including a first ID code and one of a plurality of function codes; anda receiver for receiving the transmission code, the receiver including:a storage unit for storing a second ID code,a signal processing unit for comparing said received first ID code with said second ID code stored in said storage unit, and for generating a control signal to a controlled unit when the first ID code matches said second ID code, the control signal corresponding to said received function code; anda mode control unit for setting an operation mode of the signal processing unit from a normal mode, in which the signal processing unit transmits said control signal to said controlled unit, if the first ID code matches said second ID code, to one of (a) an ID code write mode in which said received first ID code is written into said storage unit in response to a first predefined supply state of an externally applied information and a received transmission code, (b) a control signal output stop mode in which an output of said control signal from said signal processing unit is stopped even if the first ID code matches said second ID code, in response to a second predefined supply state of an externally applied information and a received transmission code, and for resetting said operation mode of said signal processing unit from said control signal output stop mode to said normal mode when said operation mode of the signal processing unit is set in said control signal output stop mode, in response to a third predefined supply state of an externally applied information and a received transmission code.
