What is the difference between a fixed code wireless remote control and a learning code?
The so-called fixed code wireless remote control: refers to the wireless remote control using the encoding chip such as 2260/2262/2264. Before use, it is necessary to weld the edit code of the remote control IC. This is the fixed code remote control that we often say. Weigh code remote control. The fixed code remote control has 6000 combinations of data. Compared with the learning code and the rolling code, the fixed code has a higher repetition rate and a relatively poor encryption. The paired receiving and decoding chip is 2270/2272/2294, etc., and one receiving end can be equipped with several, dozens, and hundreds of wireless remote controllers. Commonly used: gate remote control, telescopic door remote control, rolling door remote control, wireless remote control light switch. An application environment that requires multiple receivers to match multiple transmitters is required. Currently, a wide range of remote controls are used.
Learning code remote control: refers to the wireless remote control using 1527/2240/101 learning code chip. Before use, you need to use the remote control to align the learning button on the host to learn the code. You don't need to open the case and re-encode before use. The learning code remote control has a data combination of one million, and the re-rate and confidentiality are relatively good. The paired receiving chip is decoded by the single chip microcomputer, and the corresponding decoding program is placed. A receiving end can generally be equipped with sixteen wireless remote controls. Commonly used: garage door remote control, alarm remote control, rolling door remote control, wireless remote control light switch, smart home remote control, etc. need a receiver to match multiple transmitters. The learning code remote control is currently the most widely used remote control. The old remote control is easy to match, and the learning code remote control is very popular among consumers.
