[Industrial applications]

 The present invention relates to a transmitter / receiver, and more particularly to a transmitter / receiver that is compact and miniaturized and is compatible with a large number of receivers.

[0002]

[Prior art]

 In general, some conventional transceivers use an integrated circuit, but the code is set by switching and controlling between a plurality of ON / OFF terminals arranged by a DIP (dual inline package) switch. Since the DIP switch has a relatively large volume and occupies a considerable space and is built in the transmitter / receiver, the transmitter / receiver must be disassembled each time the code is reset, which is inconvenient for the work. is there. Therefore, the code is often fixed and operated during use, and the function is limited to controlling one receiving device by one transmitting device.

As can be seen from the above, the conventional transmitter / receiver has the following problems: (1) Since the volume is large, it occupies a large space. (2) The code is fixed and cannot be easily changed, and the device must be disassembled to change it, which is inconvenient for the user. (3) One transmitting device can control only one receiving device, and if a large number of receiving devices must be controlled at the same time, a trouble occurs in use.
