8. Support coding chip model: EV1527, PT2262, 2264, 2260 other customization

When the remote control button is pressed, the output of D0, D1, D2, and D3 is high level, and when it is not pressed, it is low level.

Clear and match the code: (Before switching the mode, clear the code first)

Compatible with all fixed code encoding chips: such as PT2262, PT2260, SC2260, EV1527, PT2240, SC1527, HS1527, RT1527 and other remote controllers

Jog, self-lock, interlock, three working modes can be switched
Multi-key remote control combination output
1: Clear memory:
Press and hold the Key 8 times and then release it after normal power-on or at any time, the LED flashes 3 times quickly to indicate correct removal
2: Switch the working mode The method is as follows (the memory must be cleared before switching the working mode)
Under the power-on state, press the Key once and then release the button to enter the jog mode and enter the learning mode (within 5 seconds). At this time, press any key of the remote control to learn, and the remote control LED lights flash continuously 3 after learning Times completed, automatically exit the learning mode without pressing the remote control for 5 seconds
Under the power-on state, press the Key 2 times and then release the button to enter the self-locking mode and enter the learning mode (within 5 seconds). At this time, press any key of the remote control to learn, and the LED light of the remote control flashes continuously 3 after learning Times completed, automatically exit the learning mode without pressing the remote control for 5 seconds
Under the power-on state, press the Key 3 times and then release the key to enter the interlocking mode and enter the learning mode (within 5 seconds). At this time, press any key on the remote control to learn, and the remote control LED light flashes 3 consecutively after learning Times completed, automatically exit the learning mode without pressing the remote control for 5 seconds
Repeated learning of the same remote controller does not occupy the storage amount, and a total of 40 remote controllers with different address codes can be learned
3: Explanation of working mode:
Jog: Press and hold the remote control button, the corresponding data pin outputs high level, and release the remote control button, the corresponding data pin becomes low level
Self-locking: Press and hold the remote control button, the corresponding data pin outputs high level, release the remote control button, the corresponding data pin is still high, and press the remote control button again, the corresponding data pin becomes low level (cycle)
Interlock: Press and hold the remote control button, the corresponding data pin outputs high level, release the remote control button, the corresponding data pin is still high level, press the same button on the remote control again, the corresponding data pin is still high, press the remote control Another button, the corresponding data pin of the remote control becomes the low frequency last time, this time the data pin corresponding to the key outputs the high frequency (and so on)

Wiring and testing

1. Correctly regulate the wiring according to the control function required by yourself. After the wiring is completed, check whether the wiring is correct. Do not operate the wiring and trial wiring with power. If there is any irregular operation, the company will not be responsible.

2. After confirming that the wiring is correct, turn on the power.

3. Press the remote control button of the code, and the remote control switch controls the corresponding control object. If the control is normally controlled, it means that the wiring test is successful and can be used normally.

common problem

1. Turn on the power supply, and clear code and code can be performed at any time. When the circuit is working, the clearing function is performed. After the clearing is successful, the 4-way relay returns to the normal state. When the LED function is lighted, the code enters the code status. The learning waiting time is about 6 seconds. It is necessary to complete the code within 6 seconds. After 6 seconds, the LED indicator is off and the program automatically exits the code status.

2. When using for the first time, be sure to clear the code once and empty the factory test to store the remote control code. After the code is successful, the valid remote control code LED will be lit.

3. The control switch can store 40 remote control codes. If 41 remote control codes are learned, the program will automatically overflow the first remote control code. And so on. When the remote control code is confusing, it should be cleared before learning, so as to avoid interference from other remote control codes.

4. The remote control used needs to learn after coding, because the general coded remote control has no code when it leaves the factory. It is ok to use it directly, but it will be controlled by other remote controllers without coding.

5, use the installation to avoid interference sources and form a similar shield cover environment. Directly affects the receiving sensitivity.

6, do not use it abnormally. Abnormal use will reduce the performance and longevity of the product. If it is serious, it will directly damage the product and bring hidden danger to your safety.
