Setup and Installation
Wiring the Receiver
The RX-MULTI receiver features terminals for power (PWR), two channels (CH1, CH2), ground (GND), and antenna (ANT). Connect the receiver to your gate automation system, garage door opener, or other device according to its specific wiring requirements. Ensure proper polarity for DC power connections.

Power Input Selection (PIS)
The receiver supports an operating voltage of AC/DC 9V-30V. Adjust the Power Input Selector (PIS) pins based on your power supply:
- If the input voltage is greater than 24V, shorten pins 2 & 3.
- If the input voltage is less than 24V, shorten pins 1 & 2.
Replacing an Old Receiver or Adding New Remotes
The RX-MULTI can replace an existing garage door receiver or be added to an existing system to increase the number of supported remote controls. It can store up to 400 remote controls, significantly expanding your system's capacity.

Programming Instructions
To program a new remote control to the RX-MULTI receiver, follow these steps:
- Select Remote Brand/Frequency: Identify the correct brand and frequency for the remote control you wish to program. Use the 8 dip switches on the receiver to set the corresponding combination (UP or DOWN). For example, for 433.92MHz Flor-s remote controls, move Dip-switch 8 UP. Refer to the provided diagrams for common configurations.
- Initiate Learning Mode: Press the 'Learn' button on the receiver. The LED indicator will turn on, signifying that the receiver is in learning mode.
- Program Remote Button: Press the desired button on your remote control. The receiver's LED will flash 4 times, indicating successful programming of that button.
- Repeat for Additional Buttons: If your remote has multiple buttons you wish to program, repeat step 2 and 3 for each additional button.
- Second Channel Programming: The programming procedure for the second channel (CH2) is identical to the first channel (CH1).

Erasing All Stored Data
To erase all programmed remote controls from the receiver's memory:
- Press and hold either 'Learn' button on the receiver.
- The LED indicator will begin to flash. Continue holding the button.
- Release the button only after the LED turns off. All saved data will be permanently erased and cannot be recovered.

Troubleshooting
- Remote not responding: Ensure the remote control has fresh batteries. Verify that the dip switches on the receiver are correctly set for the remote's frequency and encoding type. Re-attempt the programming steps.
- Limited range: Check that the antenna is properly connected and extended. Ensure there are no major obstructions (e.g., thick walls, metal structures) between the remote and the receiver. Large electrical devices nearby can also cause interference.
- Programming failure: Double-check the dip switch settings. Ensure you are pressing the 'Learn' button correctly and observing the LED feedback. If multiple remotes are programmed, try erasing all data and reprogramming them one by one.
- No power to receiver: Verify the AC/DC 9V-30V power supply is connected correctly and providing the specified voltage. Check the Power Input Selector (PIS) pins are set appropriately for your voltage.
User Tips
No specific user tips were available from reviews or Q&A for this product. However, general advice for remote control receivers includes:
- Always test the range of your remote control after installation to ensure reliable operation.
- Keep a spare remote control or ensure multiple users have access to prevent being locked out.
- If you experience intermittent issues, check for potential sources of radio frequency interference in the vicinity.
