5.2配線

Connect the red wire to the positive (+) power supply (DC5V, 2.5V-5.5V) and the black wire to the negative (-) ground. Ensure correct polarity to prevent damage to the unit.

5.3 アンテナの設置

Important: Please install the antenna before powering up the unit for a longer use life.

Carefully attach the antenna to the designated connector on the VTX camera. Ensure it is finger-tight but do not overtighten.

6. 操作

Figure 7: User Guide for LED indications and setting procedures.

6.1LED表示

• の 赤色LED indicates the state of working mode or the item being set for the VTX.
  • Flashing 1 time: Selecting channels.
  • Flashing 2 times: Selecting bands.
  • Flashing 3 times: Selecting image flip.
• の 青色LED indicates the value of the item being set for the VTX.
  • For channels: Flashing times correspond to the channel number (e.g., 3 flashes for channel 3).
  • For bands: Flashing times correspond to the band (e.g., 1 flash for band A, 2 for band B, etc.).
  • For image flip: 1 flash means vertical picture reversal.

6.2 Working Mode Indication

After powering up, the red and blue LEDs will signal the following three items of VTX in turn: channel, band, and image flip. The flashing times of the red and blue LEDs indicate the item and its respective value. After this sequence, the LEDs indicate the working modes:

• 通常操作: Both Red & Blue LEDs are ON.

6.3 Setting Channels, Bands, and Image Flip

Use the single button on the VTX camera to adjust settings:

1. チャンネルを選択: Press and hold the button until the Red LED flashes 1 time. Then, press the button repeatedly to cycle through channels. The Blue LED flashing times correspond to channels 1-8.
2. バンドを選択: Press and hold the button again (after channel setting) until the Red LED flashes 2 times. Then, press the button repeatedly to cycle through bands. The Blue LED flashing times correspond to bands A-F.
3. Select Image Flip: Press and hold the button again (after band setting) until the Red LED flashes 3 times. Then, press the button to toggle the vertical picture reversal.
4. 保存して終了: Finally, press and hold the button to save the settings and exit the VTX setting mode. This step is essential for applying your changes.

8. メンテナンス

• クリーニング: Keep the camera lens clean from dust and debris for optimal image quality. Use a soft, lint-free cloth.
• ストレージ: Store the unit in a dry, cool place away from direct sunlight and extreme temperatures.
• 物理的検査: Periodically check for any loose connections or physical damage to the wires and components.

9。 トラブルシューティング

• No Video Signal / Poor Signal:
  • Ensure the antenna is properly installed and securely connected before powering up.
  • Verify that the VTX channel and band match your FPV receiver settings.
  • Check power connections for correct voltageと極性。
• 過熱:
  • Make sure there is enough space for airflow when installing the module on the drone to prevent overheating. Overheating can trigger protection mechanisms and reduce power output.
• Incorrect Image Orientation:
  • Use the button setting procedure (Section 6.3) to adjust the image flip function if the video feed is vertically reversed.

10. ユーザーのヒント

• 互換性: When integrating with a flight controller (e.g., Cetus X), always verify the voltage requirements and wiring diagrams to ensure compatibility and prevent damage.
• 電源管理: Ensure your drone's power distribution system can adequately supply the required DC5V (2.5V-5.5V) and 220mA current for stable operation.
• アンテナのお手入れ: The antenna is crucial for signal quality. Avoid bending or stressing it excessively.
