5. Installation and Setup

Before beginning installation, ensure all power to the automation system is disconnected. The R93/RX20/U receiver is designed for integration into existing control panels or enclosures.

5.1 Mounting

Choose a suitable location within the control panel or a separate protective enclosure. The location should be dry, protected from direct sunlight, and away from large metal objects that could interfere with radio signals.
Secure the receiver using appropriate screws or mounting hardware (not included) through the designated mounting holes on the enclosure.
Ensure adequate ventilation if installing in a confined space.

5.2 Wiring

Connect the receiver to the control unit according to the following guidelines. Refer to your automation system's control panel manual for specific connection points.

Power Supply: Connect the 12/24 V AC/DC power supply to the designated power input terminals on the receiver. Observe polarity if using DC power.
Relay Outputs: The receiver has two relay outputs. Connect these outputs to the corresponding input terminals on your automation system's control board. These outputs typically trigger actions like opening/closing a gate or activating a light.
Antenna: Connect the 433.92 MHz antenna (if external) to the receiver's antenna terminal. Position the antenna for optimal signal reception, away from metal obstructions.

Note: Incorrect wiring can damage the receiver or the connected automation system. If unsure, consult a professional electrician or installer.

6. Operating Instructions

Once installed and powered, the receiver is ready to receive signals from programmed 433.92 MHz fixed code transmitters. When a valid signal is received, the corresponding relay output will activate, triggering the connected function in your automation system.

6.1 Programming Transmitters (Remote Controls)

The R93/RX20/U receiver can store up to 50 unique fixed codes. The programming procedure typically involves a button on the receiver itself. Consult the specific instructions provided with your ROGER TECHNOLOGY transmitter for detailed pairing steps, as these can vary slightly.

Locate the programming button (often labeled "PROG" or "LEARN") on the receiver module.
Press and hold the programming button for approximately 2-3 seconds until an indicator LED (if present) illuminates or changes state. This indicates the receiver is in learning mode.
While the receiver is in learning mode, press the desired button on your 433.92 MHz fixed code transmitter.
The receiver's LED should flash or change state again to confirm successful programming.
Repeat for any additional transmitters or buttons you wish to program, up to the maximum of 50 codes.
To exit learning mode, wait for the receiver to automatically time out (usually after 10-15 seconds) or press the programming button briefly again.

6.2 Erasing Programmed Codes

To erase all programmed codes from the receiver's memory:

Press and hold the programming button for approximately 8-10 seconds.
The indicator LED will typically flash rapidly or remain solid for a moment, then turn off, indicating all codes have been erased.
Test the previously programmed transmitters to confirm they no longer activate the receiver.

7. Maintenance

The ROGER R93/RX20/U receiver is designed for reliable, low-maintenance operation. However, periodic checks can help ensure its longevity and performance.

Cleaning: Keep the receiver's enclosure clean and free from dust and debris. Use a soft, dry cloth. Do not use abrasive cleaners or solvents.
Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion.
Environment: Ensure the operating environment remains within the specified temperature and humidity ranges.
Antenna: Verify the antenna is securely connected and positioned optimally for reception.

8. Troubleshooting

Problem	Possible Cause	Solution
Receiver does not respond to transmitter.	No power to receiver. Transmitter not programmed. Transmitter battery low/dead. Transmitter out of range. Interference. Faulty wiring.	Check power supply connections and voltage. Program the transmitter (see Section 6.1). Replace transmitter battery. Move closer to the receiver. Check for nearby sources of radio interference. Verify all wiring connections are correct and secure.
Limited reception range.	Poor antenna positioning. Obstructions (metal, concrete). Interference.	Reposition antenna for better line of sight. Ensure antenna is not obstructed by metal. Identify and mitigate sources of interference.
Receiver LED not illuminating.	No power. Faulty unit.	Check power supply. Contact technical support if power is confirmed.
