5. Setup

Follow these steps for proper installation and initial setup of your VTX module:

1. Mounting: Securely mount the VTX module to your RC drone or application platform using appropriate hardware. Ensure it is protected from physical impact and has adequate ventilation. The mounting hole spacing is approximately 30.5x30.5mm (1.20x1.20in).
2. Antenna Connection: Carefully screw the provided antenna onto the SMA connector of the VTX module. Ensure it is finger-tight but do not overtighten. Never power on the VTX without the antenna connected.
3. Wiring: Connect the VTX to your flight controller or power distribution board. The connecting cable typically includes wires for power (DC 7-36V), ground (GND), video input (VIDEO), and potentially audio input (AUDIO). Refer to your flight controller's manual for specific wiring diagrams.
4. Power Source: Connect the VTX to a power source within the specified voltage range (2-8S LiPo battery).
5. Camera Connection: Connect your FPV camera's video output to the VTX's video input.

6. Operating Instructions

Once installed, operate your VTX module as follows:

1. Power On: Apply power to your drone system. The VTX module will power on.
2. Channel Selection: The module supports 9 channels (1060MHz-1380MHz). Channel selection is typically done via a button or dip switches on the module, or through a flight controller's OSD (On-Screen Display) using the IRC Tramp telecommunication protocol. Consult your flight controller's documentation for VTX control.
3. Power Output Adjustment: The module offers adjustable power outputs: PIT, 25mW, 200mW, and 1600mW. Adjust the power output according to your needs and local regulations. Higher power outputs increase range but also generate more heat.
4. Receiver Pairing: Ensure your FPV receiver is set to the same frequency and channel as your VTX module to receive the video signal.

7. Maintenance

• Cleaning: Keep the module clean and free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning. Avoid using liquid cleaners.
• Storage: Store the VTX module in a dry, cool environment away from direct sunlight and extreme temperatures.
• Physical Inspection: Periodically inspect the module for any signs of damage, loose connections, or corrosion.
• Antenna Care: Ensure the antenna is not bent or damaged, as this can affect signal quality and range.

8. Troubleshooting

• No Video Signal:
  • Check power connections to the VTX.
  • Verify antenna is securely connected.
  • Ensure VTX and receiver are on the same channel and frequency.
  • Inspect video input/output connections from camera to VTX.
• Poor Video Quality/Short Range:
  • Check antenna condition and orientation.
  • Increase VTX power output (if legally permissible and cooling allows).
  • Ensure there are no obstructions between the VTX and receiver.
  • Check for sources of interference (e.g., other electronic devices, nearby Wi-Fi).
• Overheating:
  • Reduce power output if not needed.
  • Improve airflow around the module.
  • Ensure the module is not in an enclosed space without ventilation.
