无线 433M 遥控器使用说明

1. The code has 24 bits, BYTE0+BYTE1+BYTE2+end bit

BYTE0, BYTE1 is the address code.

Address code can be set as fixed address code 0000, or other address value.

Or it can be set as scroll code. Address code of each remote control is different. Scroll

code can realize one-to-one function that one remote control can only control one

receiving device.

BYTE2

BYTE2 is the key code value, the code value of each key is fixed

The following figure shows the key value of K1 = 01, the address code

is 20, 03

1. There is a combination operation. 3F will be sent if key 0D

and key 0F are pressed at the same time. This operation can

be used for learning key code.

2. The code value is hexadecimal, and the address code is

different for each remote control, so that one remote control

can control one device without interfering with each other.

If there is no requirement for one-to-one receiving function of remote control, receiving program can be made to compare the key code without comparing the address code. 接收解码编程说明 Receive decoding programming instructions When the remote control does not send signal 433, the signal foot of wireless receiving chip (DATA) is irregular miscellaneous waveform, which is normal.
