Product Overview
The ROGER R93/RX12A/U is a compact 2-channel radio receiver designed for integration into various control systems. It comes housed in a durable plastic casing, protecting its internal circuitry.
Figure 1: ROGER R93/RX12A/U Receiver (internal view). The image shows the receiver's circuit board removed from its plastic housing. Key components visible include two blue electrolytic capacitors, several integrated circuits, red push-buttons labeled "MODE", and a green screw terminal block for wiring connections. The model number "R93/RX12A/U" and "ROGER TECHNOLOGY" are printed on the PCB. The black plastic housing is shown separately, indicating its protective function.
Key Components:
- Plastic Casing: Provides protection against environmental factors.
- Circuit Board (PCB): Contains the radio receiver module and control logic.
- Terminal Block: Green screw terminals for connecting power supply and output relays.
- MODE Buttons: Red push-buttons for programming and configuration.
- LED Indicators: (If present, not clearly visible but common) For status and programming feedback.
Setup
1. Mounting:
The receiver should be mounted in a secure, dry location, away from direct sunlight and excessive vibration. Use appropriate screws or mounting hardware through the designated mounting holes in the plastic casing. Ensure adequate space for wiring connections.
2. Wiring Connections:
Refer to the markings on the green terminal block for correct wiring. Typical connections include:
- Power Supply: Connect the appropriate DC voltage (e.g., 12V or 24V DC, check specific voltage requirements on the device or packaging) to the designated power input terminals. Observe polarity.
- Channel 1 Output: Connect to the device or system to be controlled by channel 1. These are typically relay outputs (NO/NC/COM).
- Channel 2 Output: Connect to the device or system to be controlled by channel 2.
- Antenna: Connect the supplied antenna (if external) to the antenna terminal for optimal reception.
Warning: Ensure power is disconnected before making any wiring connections to prevent electric shock or damage to the device.
Operating
Programming Transmitters:
The receiver needs to be paired with compatible 433.92 MHz transmitters. The programming procedure typically involves using the "MODE" buttons on the receiver's circuit board.
- Enter Programming Mode: Press and hold one of the "MODE" buttons (e.g., for Channel 1) until an LED indicator (if present) changes state or a specific sound is emitted.
- Transmit Signal: While the receiver is in programming mode, press the desired button on your transmitter. The receiver should acknowledge the signal (e.g., LED flashes, sound).
- Exit Programming Mode: The receiver may automatically exit programming mode after a successful pairing or after a timeout. Alternatively, press the "MODE" button again briefly.
- Repeat for Channel 2: Follow the same procedure for the second channel using its corresponding "MODE" button.
Note: Specific programming steps may vary slightly depending on the transmitter model. Refer to your transmitter's manual for detailed pairing instructions.
Maintenance
- Cleaning: Keep the receiver clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners or solvents.
- Inspection: Periodically inspect wiring connections for looseness or corrosion. Ensure the casing is intact and free from damage.
- Environmental Check: Verify that the operating environment remains within the specified temperature and humidity ranges.
