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)
1, clear function - press the learning button (not let go) "KEY" 5 seconds, after the LED indicator goes out, let go, wait until the LED indicator flashes 3 times and then go out, start to clear all the remote control code data in the memory, it means The clear function is complete.
2, the code function - press the learning button (jog mode) "KEY", the LED indicator lights up to indicate that the microprocessor enters the learning pair code state, press the matching wireless remote control button, the LED indicator flashes 3 After the second time, the code is successful. (The learning button is clicked once for the jog mode; press 2 times for the self-locking mode; press 3 times for the interlock mode; press 4 times: 1, 2 for jog, 3, 4 for self-locking; for 5 times: 1 2, jog, 3, 4 interlock; press 6 times: 1, 2 self-locking, 3, 4 interlock; press 7; 1, 2 interlock, 3, 4 interlock.) The wireless remote control switch can store 16 different remote controls and can set different working modes. (This is a one-key pair code, the program will automatically assign the data bits)
3. Pair code test - After the code is successful, when the remote control button is pressed, the corresponding D0, D1, D2, D3 output is high level.
