5.1 Hardwareforbindelse

1. Connect the camera to the VTX board using the provided wiring set.
2. Connect the VTX board to your RC drone's power source (7-26V, 2S-6S). Ensure correct polarity.
3. If using a receiver, connect the RTL8812AU Adapter to your ground station device (e.g., PC, Android phone) via a Type C connector.
4. Ensure the VTX board is securely mounted, considering the 30.5*30.5MM mount holes.

5.2 Software Setup (Windows Ground Station)

For Windows users, you can set up a ground station using OpenIPC or FPV4WIN.

• OpenIPC Official Webwebsted: https://openipc.org/supported.hardware/featured
• OpenIPC Wiki: https://github.com/OpenIPC/wiki/tree/master/en
• Windows Ground Station Downloads: https://github.com/TalusL/fpv-wfb, https://github.com/OpenIPC/fpv4win

Trin:

1. Kopier nøglen file (gs.key) to the installation directory of your ground station software.
2. Double-click to open the fpv4win program.
3. Select the correct Adapter (usually RTL8812AU).
4. Set the Channel (161 is default; this adapter works in the 5.8GHz band, with available channels ranging from 36 to 177).
5. Configure the Codec (H265 is default, offering high compression and low latency).
6. Click 'START' to begin operation.

5.3 Software Setup (Android App - FPVVue or PixelPilot)

For Android users, dedicated apps are available for FPV viewing.

• Android App Downloads: https://github.com/gehee/FPVVue_android/releases (FPVVue), https://github.com/OpenIPC/PixelPilot/releases/tag/latest (PixelPilot)

Trin:

1. Install the chosen app on your Android phone.
2. Save the key file (gs.key) to your phone's storage.
3. Open FPVVue and navigate to the WFB-NG settings menu (usually in the upper left corner).
4. Tap 'gs.key' to open the file manager and select the previously saved key file.
5. Set the Channel (161 is default; this adapter works in the 5.8GHz band, with available channels ranging from 36 to 177).
6. Configure the Codec (H265 is default, offering high compression and low latency).
7. Plug in the Receive Adapter (or network adapter) to your phone.
8. The app will prompt the current channel being used, indicating it's ready for normal operation.

5.4 Ground Station Recommendations

For optimal performance, especially regarding display and transmission delay, using Single Board Computers (SBCs) with HDMI interfaces is recommended.

• SBCs like Raspberry Pi, Radxa zero3w, or Orange Pi 5 can be used.
• These allow FPV goggles and VR goggles to be used as displays.
• Radxa zero3w is recommended for its cost-effectiveness.
• Ground Station Installation & Configuration (Radxa zero3w): https://github.com/OpenIPC/sbc-groundstations/releases/tag/zero3w-V1.5.0

5.5 Firmware-indstillinger

• The VTX primarily uses OpenIPC firmware.
• Alternatively, you can flash the Rubyfpv firmware, which offers richer settings and functions, though it may have slightly higher latency.

6. Betjeningsvejledning

Once the hardware is connected and software is configured, follow these steps to operate your Eachine Sphere Link FPV system:

1. Tænd: Connect the VTX to your drone's battery. The VTX should power on and the fan (if present) should start spinning.
2. Activate Ground Station: Launch your configured Windows ground station software (e.g., fpv4win) or Android app (FPVVue/PixelPilot).
3. Opret forbindelse: Ensure your Receive Adapter is properly connected to your ground station device. The software/app should detect the VTX and display the video feed.
4. Monitor OSD: The MAVLINK Protocol enables On-Screen Display (OSD) data. Monitor flight parameters and VTX status directly on your FPV display.
5. Kanalvalg: If experiencing interference or poor signal, try switching to a different channel within the 36-177 range supported by the 5.8GHz adapter.
6. Codec-indstillinger: For optimal performance, ensure the H265 codec is selected for high compression and low latency.

7. Brugertips

• Optimal køling: Ensure the VTX fan is unobstructed for efficient cooling, especially during prolonged use or in warm environments. Proper cooling helps maintain stable performance and extends component lifespan.
• Antenneplacering: Position your VTX antennas and receiver antennas for optimal signal reception and transmission. Avoid placing them near carbon fiber or other conductive materials that can block signals.
• Firmware Choice: While OpenIPC is standard, consider experimenting with Rubyfpv firmware if you require more advanced features and are willing to accept a potentially slight increase in latency. Always back up your current configuration before flashing new firmware.
• Ground Station Stability: For critical FPV applications, using a dedicated SBC (like Radxa zero3w) as a ground station with FPV goggles can provide a more stable and lower-latency experience compared to mobile phone apps.

8. Fejlfinding

9. Vedligeholdelse

• Rensning: Regularly clean the VTX board and camera lens with a soft, dry cloth. Avoid using harsh chemicals or solvents.
• Ventilator inspektion: Periodically check the VTX cooling fan for dust buildup or obstructions. Clean gently with compressed air if necessary to ensure proper airflow.
• Ledningskontrol: Inspect all wiring for signs of wear, fraying, or loose connections before each use. Secure any loose connections.
• Opbevaring: Store the VTX and its components in a dry, cool place away from direct sunlight and extreme temperatures when not in use.
• Firmwareopdateringer: Check the official OpenIPC and Rubyfpv websites periodically for firmware updates that may improve performance or add new features. Follow update instructions carefully.
