Second, product characteristics
Is a new high-performance high-sensitivity high-frequency receiver module, using the most advanced RF IC, superheterodyne work, stable and reliable, the decoded output, strong anti-jamming performance, widely used in all kinds of interference, poor conditions occasions, is currently the best performing areas superheterodyne receiver module, the strongest anti-jamming performance, receiving a high quality farthest high-frequency decoding receiver module.
Remote learning the code, supporting remote control abnormal convenience, you can learn on the market a variety of welding code (fixed code) remote control: If 2262 \ 2264 \ 2260, learning code remote control: Such as: 1527 \ 2240 etc.
Users can self-learning jog, self-locking, interlocking three kinds of output ways of working that can be applied to all areas of flexibility.


Third, the pin and instructions

Pin Name Function Description
1 VT valid signal output
2 D3 data output
3 D2 data output
4 D1 data output
5 D0 data output
6 5V power supply positive
7 GND power supply negative

Seven pins, from left to right VT, D3, D2, D1, D0, 5V, GND, 5V and GND which connects to DC 5 volt power supply positive and negative. VT is a valid signal output bit (receiving a valid signal, the pin output high), D0 to D3 as four data bits output pin, which correspond to the four buttons on the remote control. 5 output pin output voltage is about 4.5V, can be used to drive an external relay driver circuit; Far left there is a small hole at the position of the antenna is connected.


Fourth, the remote control to learn matching and clearing
Clear: Press button to receive board learning, learning will light becomes off, after the release, that is cleared successfully. Cleared, before all of the remote control are not supporting longer has control.
Learning:
Press the button to learn about two seconds, and learn indicator lights; Approximately four seconds, learn indicator light changes from the off; Approximately six seconds, the lamp flashes once; Eight seconds, the lamp blinks twice; Ten seconds, the indicator flashes three times. In the light blinks once, twice before, release the button, press any key on the remote control, the output mode to jog; The LED flashes twice, three times before, release the button, press any key on the remote control, then the output for the self-locking; In indicator flashes three times, release the button, press any key on the remote control, then the output is interlocked. Learning is successful, four buttons for the automatic matching.
For learning a second remote or multiple remotes, you can learn better after the first remote control, simply press the button to learn, indicator light, release the button, press the remote control to learn hair code, the indicator flashes, that means success in learning, learning different remote control codes up to 16, the same code is unlimited.

Before use to connect 50 ohm 1/4 wavelength antenna and the antenna should be straight, in order to achieve the best reception, wavelength = speed of light / frequency.
