Note
Such as close distance far requirements, it is best to pick a quarter wavelength of antenna, generally USES the 50 ohm single conductor, antenna length of 315 m about 23 cm, 433 m of about 17 cm;
Antenna position to reception module also have influence, installation, antenna as far as possible unbend, away from the screen body, high pressure, and interference source places.
When using receive frequency, decoding methods should and emission matching.

Receiving module, a total of eight external interface, it has English said. "5 v" said power connection positive, "D0, D1, D2, D3" said output, "GND" said power connection negative, "ANT" said antenna end.
Product features
1, the receiving module excellent performance, using a digital process technology, and is featured by strong anti-interference, stable performance, high reliability, no directivity, long service life, the Japanese original state import chip, high stability, low power consumption, the same remote control will not have any interference messy code phenomenon, wireless receiving emission signal, remote control distance, wall, no direction. But with the market fixed code, learning code of the same frequency at any supporting the use of the remote control, can form a complete set all the wireless remote control.
2, super-regenerative receiving module using LC oscillation circuit, containing amplification plastic, the output data signal decoding for high level signal, use is very convenient, and the price is low, so is widely used. Take four road decoding output (at the same time also can change all inching or interlock output), easy to use; Frequency point debugging easy, delivery cycle short, Product quality good consistency and high performance/price ratio.
3.Receiving module has a broader receiving bandwidth, general is + - 10 MHZ, a factory general adjustment in 315 MHZ or 433.92 MHZ (if you have special request adjustable frequency, frequency adjusting range for 266 MHZ ~ 433 MHZ. . Receiving module generally USES DC5V power supply, if there are special requirements can be adjusted voltage range.
4.Purpose: remote control switch, receiving module, motorcycle, automobile anti-theft products, home security products, electric door, rolling door, window, remote control, plugs, sockets, remote control, remote control LED sound, remote control electric door, remote control garage doors, extendable doors remote control, remote gate, sliding door, remote control door opener, close the door machine and so on gating system, remote control curtain, alarm host, alarm, remote control electric motorcycle, remote control, remote MP3, remote control lamp, remote control cars, security, in the civil and industrial supporting remote areas
