4-channel wireless codec decoding transceiver module Model:RX480E-868

This is a 4-channel wireless codec decoding transceiver module called RX480E-868. It can be used both as a transmitter module and a receiver module, transmitting and receiving can be converted to each other, which is one of its greatest features!

Module Features

1. Radio Frequency Receiver Chip, commonly used in data transmission and control systems

2. It can run independently without external MCU control

3. Multichannel Transceiver@868MHz

4. Supporting FSK and bidirectional data transmission

5. The functions of interlocking, clicking and self-locking can be converted arbitrarily without jumping lines and can be stable for a long time.

6. Code learning without manual coding

7. Built-in memory, safe and reliable

8. Extra wide operating voltage

9. Distance, high reception sensitivity and anti-interference performance

10. Packet processing, including address recognition

Q:How to distinguish at this time is the transmitter module or receiver module?

A:The red and blue indicator lights up when the module is powered on and started, after that if the red indicator blinks twice means it is in receiving mode, if the blue indicator blinks twice means it is in transmitting mode.

Q:How to convert a module to transmit/receive?

A:By pressing the module button 5 times, as follows.

Receiving to transmitting:

The conversion is successful when the red light on the receiver module flashes twice after pressing the learning button of the receiver module 5 times.

Transmit to receive:

After pressing the learning button of the transmitter module 5 times, the red indicator on the transmitter module blinks 5 times and the module changes from transmitting to receiving mode.

Q:How many functions does a receiver module have?

A:There are three working modes:Momentary,Toggle and Latching.

Momentary mode: press the learning button of the receiving module once, and the red indicator will be on after flashing once. Press the key of the transmitting module to be matched, and the red indicator of the receiving module will flash 5 times, indicating that the matching is successful.

After that, press and hold the button of the matched transmitting module, the output pin of the receiving module outputs high level, release the button, the corresponding pin output of the receiving module becomes low level.

Toggle mode: press the learning button of the receiving module twice, and the red indicator will flash for 2 times and then be on normally. Press the key of the transmitting module to be matched, and the red indicator of the receiving module will flash for 5 times, indicating that the matching is successful.

After that, press the key of the matched transmission mode, the output pin on the receiving module outputs high level and remains unchanged. Press the same key again, the corresponding pin output of the module becomes low level.

Latched mode: press the learning button of the receiving module for 3 times, and the red indicator will be on after flashing for 3 times. Press the button of the transmitting module to be matched, and the red indicator of the receiving module will flash for 5 times, indicating that the matching is successful.

Then, press the key of the matched transmission mode, and the corresponding output pins on the receiving module output high level, which remains unchanged, and other pins output low level. If two keys are pressed at the same time, all output pins on the receiving module output low level, which remains unchanged.

RESET: after pressing the learning button of the receiving module for 8 times, the red indicator light on the receiving module flashes for 8 times and then goes out, all output pin outputs become low level, and all stored transmission module addresses on the receiving module are cleared.

Special tips

Each time after using the transmitter module to transmit, the blue light of the transmitter module should blink 3 times to represent successful communication (i.e. the transmitter has transmitted and the receiver has received the signal correctly). If the blue light of the transmitter module is not blinking, check whether the receiver module is not online or not paired with the transmitter module or out of the remote control range.

Caution:

RF devices are voltage sensitive devices. If the power supply is unstable or the ripple is large, please add a filter at the power input to ensure that the power supply voltage does not exceed the maximum working voltage of the product.This device is an electrostatic sensitive device, and anti-static measures must be taken during transportation and use.Make sure that the temperature does not exceed 245 ℃ when mounting.It is recommended not to use spring antenna with rubber in application to ensure better yield of products.

5~24v ultra-wide working voltage; 400meters ultra-long transmitting and receiving distance
[ Transmitter and Receiver 2-in-1 Module ] Receive and transmit integrated, can be switched by the module button, look at the indicator to distinguish the module is a transmitter or receiver.(（After power on the blue light blinks, on behalf of the transmitter module; if the red light blinks, on behalf of the receiver module）)
4-channel transceiver, independent operation, no external MCU control, while supporting FSK, bi-directional data transmission, and built-in memory, safe and reliable.
[3 working modes] interlocking, Tap, self-locking function arbitrary conversion, no jumper, long-term stability
Adopting 868mhz working frequency, it has the characteristics of long distance, very high reception sensitivity and good anti-jamming performance.
