5. Specifications

6. Setup and Installation

Follow these steps to properly install your FPV Video Transmitter:

1. Connect Antenna: Before powering on the VTX, securely attach a compatible 5.8GHz antenna to the SMA connector. Operating the VTX without an antenna can cause permanent damage.
2. Power Connection: Connect the provided power cable to the VTX. Ensure correct polarity: typically, red for positive (+) and black for negative (-). Connect the other end to a power source within the 7-28V range on your FPV drone.
3. Video and Audio Connection (if applicable): Connect the video output from your FPV camera to the video input on the VTX using the appropriate cable. If your VTX supports audio, connect the audio output from your camera to the VTX audio input. The VTX also provides a 5V output, which can be used to power your FPV camera.
4. Mounting: Securely mount the VTX to your drone frame using appropriate hardware. Ensure it is positioned to minimize interference with other components and has adequate airflow for cooling.
5. Initial Power-Up: After all connections are secure, power on your FPV drone. The VTX will initiate its power self-check function.

7. Operation

7.1. Power Self-Check

Upon powering on, the VTX performs a built-in power self-check. This function quickly verifies if the image transmission is normal. Observe your FPV goggles or monitor for a stable video feed.

7.2. Adjusting VTX Settings (Channels and Power)

The Acouto VTX supports adjustable power and channel settings. The specific method for adjusting these settings (e.g., button presses, OSD control, or SmartAudio/TrampHV protocol) depends on your flight controller and FPV system. Refer to your flight controller's manual for detailed instructions on how to configure VTX settings.

• Channel Selection: Choose a clear channel to avoid interference with other FPV pilots.
• Power Output: Select the appropriate power level (e.g., 25mW, 200mW, 600mW, 1600mW) based on your flying environment and local regulations. Lower power is suitable for close-range flying, while higher power extends range.

7.3. Fast Frequency Lock

The VTX features fast frequency lock, which means it activates quickly without interfering with other drones already in the air. This helps maintain a clean FPV environment.

8. Maintenance

• Cleaning: Keep the VTX free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning.
• Inspections: Regularly check all connections for looseness or damage. Inspect cables for fraying.
• Antenna Care: Ensure the antenna is always securely attached and not bent or damaged. A damaged antenna can significantly reduce performance and harm the VTX.
• Storage: Store the VTX in a dry, cool environment when not in use.

9. Troubleshooting

• No Video Signal:
  • Check all power and video connections.
  • Ensure the antenna is securely connected to the VTX.
  • Verify that your FPV goggles/monitor are on the correct channel and band.
  • Confirm the VTX is receiving power within the specified voltage range.
• Poor Video Quality (Static, Lines, Flickering):
  • Check for interference from other electronic components on the drone.
  • Ensure the VTX antenna is not obstructed and is positioned optimally.
  • Try a different channel or power level.
  • Inspect the antenna for damage.
  • Ensure the power supply to the VTX is clean and stable (consider adding a capacitor if experiencing noise).
• VTX Overheating:
  • Ensure adequate airflow around the VTX.
  • Avoid operating at maximum power for extended periods in enclosed spaces.
  • Never operate without an antenna.
