Орнотуу жана орнотуу
Carefully follow these steps to install your TX805P VTX into your FPV drone. Ensure all power is disconnected before beginning installation.
- Монтаждоо: Secure the VTX to your drone frame using the 30.5mm x 30.5mm mounting holes. Ensure it is positioned to avoid interference with other components and allow for proper antenna placement.
- Зымдар диаграммасы: Refer to the diagram below for correct wiring connections.
- 7-24Vin: Connect to your drone's main battery voltage (VBAT) or a regulated power source within the 7-24V range.
- Gnd: Connect to the ground of your power source and flight controller.
- 5V чыгуу: Provides a regulated 5V output for powering a camera or other low-power accessories. Ensure the connected device does not exceed the VTX's 5V output current limit.
- Видео: Connect to the video output of your FPV camera.
- Акылдуу аудио: Connect to a UART TX pad on your flight controller for OSD control of VTX settings.
- Антенна туташуу: Connect your 5.8GHz FPV antenna to the MMCX connector on the VTX. Ensure it is securely fastened. Never power on the VTX without an antenna connected, as this can damage the unit.

Иштөө нускамалары
The TX805P VTX primarily uses SmartAudio for configuration. Manual control via the onboard button is also available.
SmartAudio Control (Recommended)
If connected to a flight controller with SmartAudio support, you can configure the VTX settings (band, channel, power level) directly from your FPV goggles' OSD menu. Refer to your flight controller's documentation for specific SmartAudio setup instructions.
Manual Control (Button)
The VTX features a single button for manual configuration. The indicator lights (Blue for FR, Green for CH) will help you navigate settings.
- Каналды өзгөртүү: Short press the button. The Green (CH) light will flash to indicate the current channel. Continue short pressing to cycle through channels.
- Өзгөртүү тилкеси: Long press the button (hold for 2-3 seconds). The Blue (FR) light will flash to indicate the current band. Continue short pressing to cycle through bands.
- Change Power Level: A very long press (hold for 5+ seconds) might enter power selection mode. The specific light pattern for power levels is not detailed, but typically involves a different flash sequence or color. It is highly recommended to use SmartAudio for power adjustment to avoid accidental high power transmission.
Индикатор жарыктары:
- Күч жарыгы: Indicates the VTX is receiving power.
- Blue Light (FR light): Тандалган жыштык тилкесин көрсөтөт.
- Green Light (CH light): Indicates the selected channel within the band.
Техникалык тейлөө
- Keep the VTX clean and free from dust and debris.
- Ensure proper airflow around the VTX, especially when operating at higher power levels, to prevent overheating.
- Regularly check antenna connections for tightness and damage. A loose or damaged antenna can lead to poor video quality and VTX damage.
- Avoid exposing the VTX to moisture or extreme temperatures.
Проблемаларды чечүү
- Видео сигнал жок:
- Check all wiring connections (power, ground, video signal) between the VTX, camera, and flight controller.
- Ensure the VTX and your FPV receiver/goggles are on the same band and channel.
- Verify the VTX is receiving power (check power light).
- Ensure an antenna is properly connected to the VTX.
- Видеонун сапаты начар / статикалык:
- Check for loose antenna connections on both VTX and receiver.
- Ensure antennas are compatible and undamaged.
- Increase VTX power output (if legally permitted and within thermal limits).
- Check for sources of electrical interference on the drone (e.g., motors, ESCs).
- Ensure the VTX is not overheating.
- VTX Not Responding to SmartAudio:
- Verify the SmartAudio wire is correctly connected to a UART TX pad on the flight controller.
- Ensure SmartAudio is enabled and configured correctly in your flight controller's firmware (e.g., Betaflight, ArduPilot).
- Check for firmware updates for both VTX and flight controller.
