Receiver Module (RX480E)

Image 2: Pinout diagram for the RX480E receiver module. Pins include GND, +V (power input), D0, D1, D2, D3 (data outputs), and VT (valid transmission indicator). An antenna connection point is also visible.

2.2. Wiring Instructions

Connect the modules according to the provided diagrams. Ensure correct polarity for power connections to prevent damage.

• Transmitter (TX118S-4): Connect DC 3V-24V to the power input pins. Connect the four key inputs (K1-K4) to ground via push buttons. An LED indicates transmission.
• Receiver (RX480E): Connect DC 3.3V-5V to the +V and GND pins. The D0-D3 pins provide output signals corresponding to the transmitter's key presses. The VT pin indicates a valid signal reception.
• Antenna: Attach the copper spring antenna to the designated ANT pin on both the transmitter and receiver modules for optimal range.

• Momentary Mode (Inching Mode): Press the learning button once. The output will be active only while the corresponding remote button is pressed.
• Toggle Mode (Self-Lock Mode): Press the learning button twice. Press a remote button once to activate its corresponding output; press the same button again to deactivate it.
• Latched Mode (Interlock Mode): Press the learning button three times. Press a remote button to activate its corresponding output. All other active outputs will automatically deactivate.

3.2. Pairing Process

After selecting the desired mode by pressing the learning button the specified number of times, the receiver enters pairing mode. While in pairing mode, press any button on your remote control. The receiver's indicator LED will flash to confirm successful pairing.

3.3. Advanced Operating Modes

The RX480E module also supports advanced combined modes such as 2-channel Toggle + 2-channel Momentary, 2-channel Latched + 2-channel Momentary, and 2-channel Latched + 2-channel Toggle. These modes require specific programming or configuration. For detailed instructions on these advanced modes, please refer to the official support resources or contact customer service.

4. Maintenance

To ensure the longevity and optimal performance of your RX480E and TX118S-4 modules, follow these simple maintenance guidelines:

• Keep Clean and Dry: Protect the modules from dust, dirt, and moisture. Avoid exposing them to extreme temperatures or humidity.
• Check Connections: Periodically inspect all wiring connections to ensure they are secure and free from corrosion.
• Power Supply: Always use a stable power supply within the specified voltage range (DC 3V-24V for transmitter, DC 3.3V-5V for receiver).
• Antenna Care: Ensure the copper spring antennas are securely attached and not bent or damaged, as this can affect signal range and reliability.

5. Troubleshooting

If you encounter issues with your RX480E and TX118S-4 modules, refer to the following troubleshooting tips:

• No Signal or Poor Range:
  • Verify that both the transmitter and receiver are powered correctly.
  • Check that the antennas are properly connected and undamaged.
  • Ensure the remote control has fresh batteries.
  • Reduce the distance between the transmitter and receiver.
  • Check for potential sources of RF interference in the environment.
• Incorrect Operating Mode:
  • Re-enter the desired operating mode by pressing the learning button the correct number of times (1 for Momentary, 2 for Toggle, 3 for Latched).
  • Re-pair the remote control with the receiver after setting the mode.
• LEDs Not Responding:
  • Confirm all wiring connections are correct and secure.
  • Check the power supply to both modules.
  • Ensure the remote control is transmitting a signal (its LED should light up when a button is pressed).
