Specifikationer

Installation och installation

Proper installation is crucial for the optimal performance of your FX2-ultimate-mini VTX. Follow these steps carefully:

1. Kabelanslutningar: The VTX uses solder pads for connections. Refer to the wiring diagram below for correct pin assignments.
   • 7V-26V Input: Anslut till ditt huvudbatterivolymtage (LiPo).
   • GND: Connect to common ground.
   • Video: Connect to the video input of your flight controller or camera.
   • 5V-Output / 12V-Output: These pads provide regulated power for your FPV camera. Choose the appropriate voltage for your camera.
   • Smart Audio: Connect to a UART TX pad on your Betaflight flight controller for OSD configuration.

3. Montering: The VTX has 30.5mm stackable holes, allowing it to be mounted directly onto your flight controller stack. Ensure proper insulation to prevent short circuits.

Bruksanvisning

The FX2-ultimate-mini VTX can be configured using its onboard button or via Smart Audio through your flight controller's OSD.

Knappstyrning:

The VTX features a single button for manual configuration of channels, bands, and power levels. Refer to Figure 3 for button location and LED indicators.

• Ändra kanaler: Short press the button to cycle through channels. The blue LED will indicate the current channel (1-8).
• Byta band: Long press the button (approx. 3 seconds) to cycle through bands. The red LEDs will indicate the current band (A, B, E, F, R).
• Changing Power Levels: After selecting a band, another long press (approx. 3 seconds) will cycle through power levels (25mW, 200mW, 600mW). The green LED indicates power.

Note: Always ensure an antenna is connected before powering on the VTX to prevent damage.

Smart Audio Configuration (Recommended):

For advanced and convenient configuration, utilize the Smart Audio feature with your Betaflight flight controller. This allows you to change VTX settings directly from your OSD or Betaflight Configurator.

1. Connect Smart Audio: Ensure the Smart Audio pad on the VTX is connected to a free UART TX pad on your flight controller (as per Setup section).
2. Betaflight Configuration:
   • In Betaflight Configurator, navigate to the "Ports" tab.
   • Enable "VTX (SmartAudio)" for the UART connected to the VTX.
   • Navigate to the "Video Transmitter" tab.
   • Select "SmartAudio" as the VTX protocol.
   • Load the appropriate VTX table if not already present.
3. OSD-kontroll: Once configured in Betaflight, you can access the VTX settings menu through your FPV goggles' OSD. Typically, this involves a stick command (e.g., throttle mid, yaw left, pitch forward) to enter the OSD menu. Navigate to VTX settings to adjust band, channel, and power.

Underhåll

To ensure the longevity and reliable performance of your FX2-ultimate-mini VTX, consider the following maintenance tips:

• Värmehantering: The VTX can generate significant heat, especially at higher power outputs (600mW). Ensure adequate airflow around the unit. Avoid prolonged operation on the bench without proper cooling or an antenna connected.
• Antennvård: Always ensure the antenna is securely connected before powering on the VTX. A loose or disconnected antenna can lead to VTX damage. Avoid bending or stressing the antenna connector.
• Renlighet: Keep the VTX free from dirt, dust, and moisture. If cleaning is necessary, use a soft, dry brush or compressed air. Avoid liquid cleaners.
• Fysiskt skydd: While designed to be robust, protect the VTX from direct impacts. Consider using a protective enclosure or mounting it in a location less prone to crash damage.

Felsökning

If you encounter issues with your FX2-ultimate-mini VTX, refer to the following common problems and solutions:

• No Video Signal / Poor Video Quality:
  • Check all wiring connections (Video, GND, Power) for continuity and correct polarity.
  • Ensure the antenna is securely attached and undamaged.
  • Kontrollera att dina FPV-glasögon/mottagare är på rätt band och kanal.
  • Check the VTX power output setting; a higher power setting might be needed for better range or penetration.
  • Inspect for physical damage to the VTX or its components.
• VTX Gets Excessively Hot:
  • This is normal at higher power outputs, but excessive heat can indicate a problem.
  • Ensure adequate airflow around the VTX. Do not enclose it in a tight space without ventilation.
  • Verify that the antenna is properly connected. Operating without an antenna will cause rapid overheating and damage.
  • Kontrollera ingångsvolymtage; ensure it is within the specified 7V-26V range.
• Smart Audio Not Working:
  • Confirm the Smart Audio wire is connected to a TX pad on your flight controller.
  • Verify that the correct UART is enabled for VTX (SmartAudio) in Betaflight Configurator.
  • Ensure the VTX protocol is set to SmartAudio in Betaflight.
  • Check for any conflicting peripherals on the same UART.
• VTX slås inte på:
  • Kontrollera ingångsvolymentage och polaritet.
  • Inspect solder joints for cold joints or short circuits.
  • Ensure your power source is providing sufficient current.
