The so-called fixed code wireless remote control is mainly a wireless remote control using 2260/2262/2264 and other coding chips. Before use, the editing code feet of the remote control IC need to be welded, which is what we often call a fixed code remote control, also known as welding code the remote control. The data of the fixed code remote control has 6000 combinations, and the paired receiving and decoding chips are 2270/2272/2294, etc. One receiving end can be equipped with several, dozens or hundreds of wireless remote controls. Commonly used in gate remote control, telescopic door remote control, rolling door remote control, wireless remote control lamp switch, etc. Applications that require one receiver to match multiple transmitters. The most widely used wireless remote control at present.The learning code wireless remote control is mainly a wireless remote control with learning code chips such as 1527/2240/101. Before use, you need to use the wireless remote control to align the learning button on the host for code learning, and you do not need to open the shell before use. . The data of the learning code wireless remote control has one million combinations, and the repetition rate and confidentiality are relatively good. The paired receiving chip is decoded by a single-chip microcomputer, and the corresponding decoding program is placed. A receiver can generally be equipped with sixteen wireless remote controllers. Therefore, it is often used in garage door remote control, alarm remote control, rolling door remote control, wireless remote light switch, smart home remote control and other application environments that require one receiver to match multiple transmitters.
