Package Contents
Verify that all components are present and undamaged upon unpacking:
- 1 x ROGER TECHNOLOGY R93/RX2RC/U 2-Channel Radio Receiver
- 1 x Plastic Casing
- 1 x Instruction Manual (this document)
Setup
1. Mounting the Receiver
- Choose a suitable location for the receiver, ensuring it is protected from environmental elements and within optimal range of the transmitters.
- Open the plastic casing carefully.
- Secure the receiver base to a flat surface using appropriate screws (not supplied).
- Ensure proper ventilation around the unit.
2. Wiring Connections
Refer to the wiring diagram printed on the circuit board or in the detailed technical documentation for specific connections. General connections include:
- Power Supply: Connect the appropriate voltage (e.g., 12/24V AC/DC) to the designated power input terminals. Observe polarity if DC.
- Antenna: Connect a 433.92 MHz antenna to the antenna input terminal for optimal range.
- Output Channels: Connect the control wires for the devices you wish to operate (e.g., gate opener, light) to the respective output terminals (Channel 1, Channel 2). These are typically relay outputs.
3. Programming Transmitters (Rolling Code)
The R93/RX2RC/U receiver uses rolling code technology for enhanced security. Follow these steps to program a new transmitter:
- Press and hold the programming button on the receiver (often labeled 'PROG' or 'LEARN') for approximately 2-3 seconds until an LED indicator lights up or flashes.
- Within 10 seconds, press the desired button on your rolling code transmitter. The receiver's LED should change its state (e.g., flash faster, turn solid) to indicate successful learning.
- Repeat for additional transmitters or buttons if necessary.
- Wait for the receiver's LED to turn off automatically, or press the programming button briefly to exit programming mode.
- Test the programmed transmitter to ensure it activates the desired output channel.
Operating
Once the receiver is installed and transmitters are programmed, operation is straightforward:
- Press the corresponding button on your programmed rolling code transmitter.
- The receiver will detect the signal and activate the associated output channel.
- The activated output will control the connected device (e.g., open/close a gate, turn on/off a light).
Maintenance
The R93/RX2RC/U receiver requires minimal maintenance:
- Regular Inspection: Periodically check the receiver and its wiring for any signs of damage, wear, or loose connections.
- Cleaning: If necessary, gently clean the exterior of the plastic casing with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Antenna Check: Ensure the antenna is securely connected and free from obstructions for optimal signal reception.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Receiver does not respond to transmitter. | Transmitter not programmed; low transmitter battery; out of range; power issue. | Reprogram transmitter; replace transmitter battery; move closer to receiver; check receiver power supply. |
| Limited operating range. | Poor antenna connection; environmental interference; receiver location. | Check antenna connection and position; identify and remove sources of interference; relocate receiver to a more open area. |
| LED indicator not lighting up. | No power to receiver; faulty unit. | Verify power supply connections; contact support if power is confirmed. |
