3. Instructions for Use
1. Status Indicator Definition
| Indicator Light | Status |
|---|---|
| Red light flashing | Data transmission disconnected |
| Blue light flashing | Data transmission establishes connection |
| Red and blue lights flash alternately | **The data transmission is in frequency pairing mode ** |
2. Frequency pairing operation
Press and hold the frequency pairing buttons of two data transmitters simultaneously for more than 3 seconds until the indicator light status changes to the red light off and the blue light on. Since networking is not supported, only two data transmitters can pair frequencies at the same time. Two paired data transmitters can communicate with each other without re-pairing frequencies after being powered on again. 
3. Interface Description
can communicate directly with the control terminal via the 4P socket, or communicate with computer and mobile phone terminals via USB. 
GND: Ground Wire
VCC: Power Line
TX: Serial Port Transmitter
RX: Serial Port Receiver

5. Precautions
The product is strictly prohibited from being used in any local war. If the purchaser privately uses it in war and all liabilities arising therefrom shall have nothing to do with the supplier.
If the product is damaged due to non-quality issues, the supplier will not provide warranty.
When receiving the product, the purchaser should conduct an unpacking test as soon as possible according to the instructions, ensure that there are no issues before installing and using it, and avoid scratching the module, which may result in the inability to return or exchange it.
When problems occur during use, the problem site should be photographed and recorded as much as possible, and the supplier should be promptly informed for handling.
For the two data transmitters in interconnected communication, their antennas need to be matched; one cannot be a T-type antenna while the other is a rubber rod antenna, otherwise the communication distance will be significantly reduced.
