- 1x Product Instruction Manual (this document)
Opstelling
1. Fisiese verbindings
Connect the provided 5P cable to the Eachine TX526 and your flight controller or power distribution board (PDB) according to the diagram below. Ensure correct polarity to prevent damage.
- GND: Grondverbinding.
- Oudio: Audio input from your camera or flight controller.
- Video: Video input from your FPV camera.
- GND: Additional ground connection.
- 7-24V: Power input. Ensure your power source is within this voltage reeks.
2. Antenna installasie
Carefully screw the provided RP-SMA antenna onto the RP-SMA Male connector on the TX526. Ensure it is finger-tight but do not overtighten. Always ensure the antenna is connected before powering on the VTX to prevent damage.
Bedryfsinstruksies
The Eachine TX526 features a single button for controlling frequency, channel, and output power. An LED display indicates the current settings.
1. Skakel aan/af
- When the VTX is powered on, if the blue LED display shows "0", the video output is currently off.
- To toggle the video output on/off, perform a long press (approximately 5 seconds) until the LED display flickers.
2. Changing Frequency Band
- To select the frequency band (FR1/A, FR2/b, FR3/E, FR4/F, FR5/r), press and hold the button for approximately 2 seconds. The LED display will cycle through the available bands. Release the button when the desired band is shown.
3. Changing Channel
- To select the channel (CH1-CH8) within the current band, short press the button (approximately 1 second). The LED display will cycle through the channels. Release the button when the desired channel is shown.
4. Changing Output Power
The output power can be switched between 25mW, 200mW, and 600mW. The LED display indicates the current power level:
- One hyphen (-): 25mW
- Two hyphens (--): 200mW
- Three hyphens (---): 600mW
To cycle through the power levels, perform a short press on the power switch button. The LED display will update to show the selected power level.

Onderhoud
- Skoonmaak: Keep the VTX free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning.
- Fisiese beskerming: Avoid physical impacts or excessive force on the VTX and its connectors.
- Berging: Store the VTX in a cool, dry place when not in use.
- Antenna sorg: Always ensure the antenna is securely connected before powering on. Never operate the VTX without an antenna, as this can permanently damage the unit.
Probleemoplossing
- Geen videosein nie:
- Check all wiring connections (power, video, ground) for proper seating and polarity.
- Ensure the VTX is receiving power within the 7-24V range.
- Verify that your FPV receiver is set to the exact same frequency band and channel as the TX526.
- Confirm the VTX video output is enabled (not showing '0' on the LED display).
- Poor Video Quality / Static:
- Check antenna connections on both the VTX and receiver. Ensure they are compatible and undamaged.
- Try changing to a different channel or band, as there might be interference on the current frequency.
- Increase the VTX output power (200mW or 600mW) if operating at a distance or in an environment with obstacles.
- Ensure there are no major sources of electromagnetic interference near the VTX or receiver.
- VTX Oorverhitting:
- Ensure adequate airflow around the VTX, especially when using higher power outputs (200mW/600mW).
- Avoid prolonged operation on the bench without cooling.
Gebruikerswenke
- Hittebestuur: FPV transmitters, especially at higher power outputs, can generate significant heat. Ensure your TX526 has sufficient airflow when mounted on your drone to prevent overheating and potential damage. Consider mounting it in a location where it can dissipate heat effectively.
- Antenna Protection: The antenna is crucial for signal transmission. Protect it from crashes and ensure it's always connected before powering on the VTX.
- Kraguitsetkeuse: Use the lowest effective power output (25mW) for short-range flying or when flying with others to minimize interference. Only switch to higher power (200mW/600mW) when necessary for longer range or challenging environments.
