Description: learning code 433Mhz RF Wireless receiver Module

 

Product Detail:

DL-R47AL is a very excellent super regeneration receiver module with 6 outputs. This module was designed in RF integrated circuit. It has the feature of stable frequency and high sensitivity. The encode IC of EV1527 make this module to be used directly. It can be applied in all kinds of wireless remote control which require 6 outputs, like car, motorcycle, electric vehicle and illumination.

 

1. Application:

a. Anti-theft alarm for car, motorcycle;

b. Industrial remote control, remote measurement and remote sensing;

c. Anti-theft alarm signal receiving and various remote controls for home-appliances;

d. Remote control for intelligent toy;

e. Remote control for garage door and barriers etc.

4. Learning method:

  a. Unlatch: press the learn button 1 time, when the led was on, then press any button on the remote control to learn the code, after learning, all 6 outputs are unlatch. Unlatch means when you press the button 1 on the remote control, D0 will be on, release the button 1, D0 will be off;

  b. Interlock: press the learn button 2 times, when the led was on, then press any button on the remote control to learn the code, after learning, all 6 outputs are interlock. Interlock means when you press the button 1 on the remote control, D0 will be on, when you press the button 2, D1 will be on, but D0 will be off. Always only output will be on;

  c. latch: press the learn button 3 times, when the led was on, then press any button on the remote control to learn the code, after learning, all 6 outputs are latch. Latch means when you press the button 1 on the remote control, D0 will be on, when you press button 1 again, D0 will be off, each output will work independently;

  d. Signal delay: press the learn button 4 times, when the led was on, then press any button on the remote control to learn the code, after learning, all 6 outputs are signal delay. Signal delay means when you press the button 1 on the remote control, D0 will be on, after 3 seconds, D0 will be off automatically. The same operation for the other outputs.

 

5. Delete the saved information on the receiver module:

  a. Press the learn button of the receiver module until the led extinguish, that means the code saved in the receiver module as been deleted.

  b. Delete the saved information each time before learning different working mode.

 

6. Notes for usage

a. Pls use soft lead wire or other hard metal (like telescopic antenna), It can not be either too long or too short, or it will affect the receiving distance. The antenna should be stretched as straight as possible if it is using soft lead wire, and as far as possible from the metal objects.

b. The power voltage needs to be stable with low ripple factor and multilevel wave filtering (such as adding magnetic ball, inductance, capacitance etc.)

c. We suggest the clock frequency of the MCU should be lower than 4MHZ if used together with MCU, the crystal should be as far as possible to the RF receiving module, or the higher harmonic of the crystal will affect the communication distance.
