The package includes various connection cables, such as the K V2 cable, designed for interfacing the receiver with different flight controllers (e.g., JIJI/VK/BOYING) and other drone components. Refer to your flight controller's manual for specific wiring diagrams.

4. Setup and Installation

Follow these steps to properly install and set up your Skydroid T12/SG12-RX Receiver.

1. Antenna Connection: Carefully connect the two 2.4G antennas to the designated "2.4G ANT-" ports on the receiver unit. Ensure they are securely fastened but do not overtighten. Position the antennas away from metal objects and at a 90-degree angle to each other for best signal diversity.
2. Power Connection: Connect the receiver to a stable 5V power source. Use the VCC and GND pins for power input. Ensure correct polarity to prevent damage. The USB5V port can also be used for power during configuration or testing.
3. Flight Controller Connection: Connect the receiver to your drone's flight controller using the appropriate cable (e.g., K V2 cable). Common connection methods include:
   • S.BUS: Connect the Sbus pin on the receiver to the S.BUS input on your flight controller. This is a common single-wire digital protocol.
   • UART (Rx/Tx): For serial communication, connect Rx1/Tx1 or Rx2/Tx2 (or Rx3/Tx3) to the corresponding UART ports on your flight controller.
   • PWM: If using traditional PWM, connect the DM/CH9 and DP/CH10 pins to the respective PWM input channels on your flight controller.
   Refer to your flight controller's manual for specific wiring and configuration details.
4. Binding (Pairing): To establish communication between the receiver and your Skydroid remote controller, a binding process is required. Typically, this involves:
   • Power on the receiver while holding down the MODE KEY.
   • Observe the LED indicators for binding status (refer to your remote controller's manual for specific LED patterns).
   • Initiate the binding process on your Skydroid remote controller.
   • Once successfully bound, the LEDs on the receiver will indicate a solid connection.

5. Operating Instructions

Once the receiver is installed and bound to your remote controller, it will facilitate communication for controlling your drone.

• Power On Sequence: Always power on your remote controller first, then the drone (which powers the receiver). This ensures the receiver establishes a link with the controller before the flight controller initializes.
• LED Indicators:
  • RED LED: Indicates power status or error conditions.
  • GN LED: Indicates signal reception and connection status. A solid green light typically means a stable connection.
  Consult your Skydroid remote controller's manual for detailed LED status interpretations.
• Signal Loss: In case of signal loss, the receiver will typically enter a failsafe mode, as configured on your flight controller. Ensure your failsafe settings are properly configured for safe operation.

6. Maintenance and Care

Proper maintenance ensures the longevity and reliable performance of your receiver.

• Keep Clean: Regularly clean the receiver unit with a soft, dry cloth. Avoid using solvents or abrasive cleaners.
• Protect from Elements: Shield the receiver from moisture, dust, and extreme temperatures. If used in a plant protection drone, ensure it is adequately protected from liquids and chemicals.
• Inspect Connections: Periodically check all cable connections and antenna attachments for looseness or damage. Replace any worn or damaged components immediately.
• Firmware Updates: Check the official Skydroid website for any available firmware updates for your receiver. Follow the provided instructions carefully for updating.
