4. Warnings and Important Considerations

The XILO STAX 5.8GHz FPV Video Transmitter is a compact and feature-rich device designed for FPV (First Person View) applications, enabling wireless video transmission from a drone or other remote-controlled vehicle to a receiver. It incorporates "LOCK-ON TECH" to eliminate frequency drift and provides all-channel power calibration for stable and reliable video feeds. The device is designed to operate without frequency sweep or interference, ensuring a clean signal.

Important Technical Specifications:

• Input Voltage: The VTX operates on a wide input voltage range of DC 7-36V, making it compatible with up to 6S LiPo batteries. It features dual power filters to ensure clean power delivery.
• Output Voltage: It provides a DC 5V output with a maximum current of 600mA, primarily intended for powering a camera.
• Power Levels: The transmitter offers multiple selectable power levels: PIT mode, 25mW, 100mW, 200mW, and 600mW. Note that certain higher power levels may require a HAM license to operate legally and might only be available on special request, with the US version not including all channels.
• Channels: It supports 37 channels (US version) across various bands including Band A, Band B, Band E, Band F, and Raceband.
• Video Format: Compatible with both CVBS PAL/NTSC video formats.
• Audio: Includes 6.5M MONO audio with support for RUSH AGC MIC.
• Dimensions: The unit is compact, measuring H 36.5mm x W 36.5mm x D 5.2mm.
• Weight: Weighs 4.5g without the cable.
• External Control: Features SmartAudio for external control, which is a TBS authorized commercial protocol.

Usage Features:

The XILO STAX VTX is designed for ease of use and integration into FPV systems.

• Physical Controls:
  • Band/Channel Button: A short press changes the channel, while a long press changes the band.
  • Power Level Button: A short press changes the power level, and a long press turns PIT MODE ON/OFF.
• SmartAudio Integration: The VTX incorporates the official licensed TBS SmartAudio protocol, allowing for quick and convenient parameter adjustments via the OSD (On-Screen Display) or radio control when connected to a Flight Controller (FC) or CF receiver.
  • Connection: Connect the SmartAudio port of the VTX to a spare UART-TX on the Flight Controller.
  • BetaFlight Configuration: In the BetaFlight configurator, navigate to the Ports Tab, select "TBS SmartAudio" from the Peripherals dropdown menu, and save settings.
  • OSD Menu Access: To access the OSD menu, turn on your radio control, set the THR (throttle) to middle, YAW left, and PITCH up.
  • VTX SA Menu: Within the OSD menu, select "FEATURES" then "VTX SA" to set the VTX to its working state.
  • Mode Configuration: In the CONFIG menu, setting the VTX to "RACE" mode will automatically boot it up in PIT mode. Setting it to "FREE" mode will allow it to transmit normally after booting up. Switching between these modes requires disconnecting and reconnecting power for the setting to take effect.
  • OSD Menu Options: The SmartAudio VTX top menu (Band/Channel mode) provides options for:
    • Device status
    • Band selection
    • Channel selection
    • Frequency of selected band and channel (read-only)
    • RF power selection
    • Commencing current selection
    • Configuration menu
• Power Level Indication: The power LED indicator flashes when the VTX is in PIT mode. A long press of the power button exits PIT mode and activates the current power level. The LED color indicates the selected power level: Green for 25mW, Yellow for 100mW, Red for 200mW, and Purple for 600mW.
• Channel and Band Indication: The device uses a combination of LED indicators (LED OFF, LED FLASH, LED ON) to visually represent the selected channel and band.

Maintenance Features:

• Antenna Connection: It is crucial to connect the antenna before powering on the unit to prevent damage to the precision components inside.
• Cooling: The VTX can get hot during operation, so it must be mounted in a way that ensures adequate airflow for cooling to prevent burns.
• Wiring Diagram: A clear wiring diagram is provided to ensure correct cable and plug fitments.
• 5V Output Usage: The 5V output is specifically for powering the camera only. It should not be connected to a power input or battery supply, as this will cause damage to the VTX.
• Signal Integrity: For the best video image, it is recommended to keep video signal cables away from components that can cause electrical interference, such as an ESC (Electronic Speed Controller).
• Breakaway Tabs: The physical design includes breakaway tabs, which might be used for mounting or to reduce the footprint if certain parts are not needed.

Warnings and Important Considerations:

• Professional Knowledge: Users should possess relevant professional knowledge for installing and operating the VTX. Improper use can lead to potential danger.
• Local Regulations: Adherence to all local radio regulations is mandatory. A HAM license may be required for certain channels and power levels. Users must notify local radio regulatory agencies before using some frequencies and abide by all laws and regulations for drones and transmitting power.
• No-Fly Zones: It is strictly forbidden to fly in no-fly zones such as airports, military facilities, or overcrowded areas.
• No Disassembly/Modification: Users should not disassemble, repair, or modify the product personally. Technical support should be sought from the dealer for any questions or problems.
• Responsibility: The user accepts responsibility for any personal injury and property damage resulting from ignoring the provided statements or violating operating regulations.
