Diymore Wireless RF Module Receiver Instruction Manual

1. Introduction

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.

2. Specifications

3. Components Included

Each package typically includes:

• Diymore Wireless RF Receiver Module(s) (RX480-E-WQ)

Note: This manual focuses on the receiver module. Compatible transmitters are sold separately or as part of a complete kit.

4. Setup and Installation

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.

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.

1. Select Operating Mode:
   • Inching Mode (Jog Mode): Press the learning key once.
   • Self-locking Mode: Press the learning key twice.
   • Interlocking Mode: Press the learning key three times.
2. 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.
3. Clear Code:

   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. Operating Modes

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.
• Self-locking Mode: 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. Troubleshooting

• Module not powering on: Ensure the DC 3.3V-5V power supply is correctly connected to the +V and GND pins and that the voltage is within the specified range.
• 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.
  • Check for strong interference sources nearby.
• 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.
• Incorrect operating mode: 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. User Tips

• Frequency Selection: Ensure that both your receiver module and remote control operate on the same frequency (either 315MHz or 433MHz) for proper communication.
• Antenna Placement: For optimal receiving distance, ensure the module's antenna is extended and kept clear of other components or metal enclosures.
• Testing Modes: 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.
• Power Supply Stability: Use a stable and clean DC 3.3V-5V power supply to prevent erratic behavior or damage to the module.

8. Maintenance

• Keep the module in a dry environment to prevent moisture damage.
• Avoid exposing the module to extreme temperatures or direct sunlight.
• Clean the module gently with a dry, soft cloth if necessary. Do not use liquids or harsh chemicals.
• Ensure all connections remain secure and free from corrosion.

9. Field of Application

The Diymore Wireless RF Module is suitable for a variety of applications, including but not limited to:

• Access control systems
• Smart home automation (e.g., lighting, appliance control)
• Security systems
• Wireless control switches
• Hotel room control systems
• Electric vehicle remote control
• Monitoring systems
• DIY electronic projects requiring remote activation
