Black Round Self-copying Remote Control Transmitter For Electric Door Garage Gate Wireless Remote Switch 315MHz

Feature:
1. High copy accuracy and high copy efficiency.
2. The copy data code and the copy oscillating resistor have small error, and the copy does not drop code.
3. The copy oscillating resistor range is 1.2M to 6.2M wide.
4. The circuit design is stable, the button is no longer used as the power supply wire, and the high current triode is separately controlled to improve the power supply dynamics.
5. One-click smart copy to improve work efficiency.
6. Multi-functional and multi-variable, personalized and user-friendly design is simple and fast to use.
7. The imported high frequency triode is used, and the transmitting power is 13dbm. Less dead ends.
8.
Can be copied common chips: PT2264, PT2262, PT2260, PT2240, SC2262, SC2260, EV1527, SCT527, HS1527, HS2240, SCL1527, FP1527, etc., the general suffix can be the same.
9. This smart copy remote control is suitable for customers with electric door remote control, telescopic door remote control, garage door remote control, motor control remote control, curtain control remote control, car and motorcycle remote control. The copy remote control must meet the following three conditions:  
1. You must have a good remote control.
2. You need to know the crystal frequency and chip type of your remote control.
3. This remote control can copy most of the fixed code and learning code series remote control, which is mainly suitable for rolling gates, retractable doors and garage doors. Gates and so on. Please unpack your wireless remote control to see the remote internal circuit board:   A.
Frequency View: Look at the number on the wireless remote control circuit board (some people are also called crystal oscillator) (315MHZ? 433MHZ? Other 390, 418, 430 frequency? ), select the corresponding frequency. B.
Chip view: IC on the remote control board (2260? 2262? 2264? 1527? 2240? ) - the prefix of the IC is different, there may be a difference in the oscillation resistance, but the IC suffix must be the same or compatible, such as 2260/ 2262/2264 several chips are compatible, this is the fixed code is also called the welding code (requires the user to weld the custom code). If it is 1527 or 2240, this is also a fixed code (no need to encode the chip when it is shipped from the factory), so this type of remote control needs to be paired with the receiving motherboard to learn the code, so it is often called the learning code. C.
Data information: The fixed code can be viewed through the data pin weld. Others need to be detected by the copy machine or the instrument can be seen. D.
Oscillation resistance: This is a resistor connected to the oscillation pin of the remote control IC. Commonly used oscillator resistors for fixed-code chip 2262/2264 are: 1.2M (125); 1.5M (155); 2.2M (225); 3.3M (335); 4.7M (475). The oscillation resistance of the learning code chip 1527 is usually 180K (184) 270K (274); 330K (334) and the like. Mismatch in the oscillating resistor may result in a close distance or by pressing the wireless remote receiver.
