1. Úvod
The Diymore Wireless RF Module (Model: RX480-E-WQ) is a versatile receiver designed for remote control applications. This module features built-in learning code 1527 decoding, supporting both 315MHz and 433MHz frequencies. It offers multiple operating modes including inching, self-locking, and interlocking, making it suitable for a wide range of projects from smart home automation to security systems. The remote control utilizes the EV1527 encoding method, ensuring each remote has an independent address code to prevent cross-coding and mutual interference.

4.1 Pinout and Wiring
The receiver module features several pins for power, ground, and data output. Refer to the diagram below for correct wiring.
| Kolík | Popis |
|---|---|
| GND | Grounded or negative power supply |
| +V | DC 3.3V ~ 5V input power supply |
| D0 | Data output (corresponds to remote button A) |
| D1 | Data output (corresponds to remote button B) |
| D2 | Data output (corresponds to remote button C) |
| D3 | Data output (corresponds to remote button D) |
| VT | Output (often used as a status indicator or common output) |
4.2 Learning Mode Configuration
The receiver module features a 'Learning setting key' to configure its operating mode and pair with a remote control. The module adopts a key selection mode, eliminating the need for soldering or jumpers.
- Vyberte provozní režim:
- Inching Mode (Jog Mode): Press the learning key jednou.
- Režim samosvorného uzamčení: Press the learning key dvakrát.
- Interlocking Mode: Press the learning key třikrát.
- Code Matching (Pairing):
After selecting the desired operating mode, the module enters code matching mode. Press any button on your compatible remote control. The LED on the decoding module will flash three times after successfully receiving the signal, then turn off, indicating successful pairing.
If no signal is received within 6 seconds, the system will automatically exit the learning and code matching mode.
- Vymazat kód:
To clear all learned remote control codes, press the learning key eight times. The LED will flash 8 times to confirm that all codes have been cleared. It is recommended to clear existing codes before learning new ones or changing the working mode.
5. Provozní režimy
The RX480-E-WQ module supports three distinct operating modes, selectable via the learning key:
- Inching Mode (Jog Mode): In this mode, the corresponding output (D0-D3) will be high only for as long as the remote control button is pressed. Once the button is released, the output returns to a low level. This is ideal for momentary actions, like opening a gate for a brief period.
- Režim samosvorného uzamčení: When a remote control button is pressed once, the corresponding output will switch to a high level and remain high. Pressing the same button again will switch the output back to a low level. This acts like a toggle switch, suitable for turning lights on/off.
- Interlocking Mode: In interlocking mode, only one output can be active (high) at any given time. When a remote control button is pressed, its corresponding output goes high, and all other outputs (D0-D3) automatically switch to a low level. This is useful for applications where only one function should be active at a time, such as controlling multiple motors where only one should run at once.
6. Řešení problémů
- Modul se nezapíná: Ensure the DC 3.3V-5V power supply is correctly connected to the +V and GND pins and that the voltage je ve specifikovaném rozsahu.
- No response from remote control:
- Verify that the remote control is compatible (EV1527 encoding).
- Ensure the remote control has fresh batteries (if applicable).
- Confirm that the remote control has been successfully paired with the receiver module using the learning procedure.
- Zkontrolujte, zda se v blízkosti nenacházejí silné zdroje rušení.
- Short receiving distance:
- Ensure the antenna on the receiver module is properly connected and unobstructed.
- Minimize physical obstructions (walls, metal objects) between the remote and receiver.
- Avoid placing the module near other RF-emitting devices.
- Nesprávný provozní režim: Re-perform the learning mode configuration (Section 4.2) to ensure the desired mode (inching, self-locking, or interlocking) is correctly set. Remember to clear existing codes before setting a new mode.
7. Uživatelské tipy
- Výběr frekvence: Ensure that both your receiver module and remote control operate on the same frequency (either 315MHz or 433MHz) for proper communication.
- Umístění antény: For optimal receiving distance, ensure the module's antenna is extended and kept clear of other components or metal enclosures.
- Testovací režimy: Before integrating the module into a final project, thoroughly test each operating mode (inching, self-locking, interlocking) to confirm it behaves as expected with your remote control.
- Stabilita napájení: Use a stable and clean DC 3.3V-5V power supply to prevent erratic behavior or damage to the module.
8. Údržba
- Keep the module in a dry environment to prevent moisture damage.
