4. Setup Guide

4.1. Installing the TX Module

1. Pasangkeun Antena: Carefully screw the provided antenna onto the SMA connector of the Aeris Link TX module. Ensure it is finger-tight, but do not overtighten.
2. Insert into Radio: Insert the Aeris Link TX module into the JR module bay of your compatible OpenTX/EdgeTX radio transmitter. Ensure it is seated firmly.
3. Kakuatan Éksternal (Opsional): If your radio's JR bay does not provide sufficient power, or for higher output power settings, connect an external power source (5-21V, recommended 2S/8.4V) to the XT30 interface on the module.

4.2. Connecting the Micro ExpressLRS Module

The Micro ExpressLRS module is typically integrated into your FPV drone's flight controller. Refer to your flight controller's manual for specific wiring instructions for CRSF protocol. The module features a Type-C interface for firmware updates and configuration, and an XT30 port for external power if needed.

4.3. Konfigurasi awal

1. Daya Hurung: Power on your radio transmitter with the Aeris Link TX module installed.
2. Access ELRS Lua Script: Navigate to the ELRS Lua script on your radio's screen to configure settings such as binding phrase, output power, and packet rate.
3. ngariung: Ensure your Micro ExpressLRS receiver module on the drone is also powered on. Use the ELRS Lua script to initiate the binding process. Both modules must have the same binding phrase and firmware version.
4. Pembaruan firmware: For optimal performance and new features, regularly check for and update the firmware on both your TX and Micro modules using the ExpressLRS Configurator via the Type-C USB port.

5. Parentah Operasi

5.1. OLED Screen Navigation (TX Module)

The 1.29-inch OLED screen on the Aeris Link TX module provides real-time flight control information and allows for easy adjustment of settings. Use the navigation buttons (if present) or your radio's controls to browse menus and modify parameters such as:

• Daya kaluaran: Adjust transmission power from 10mW for short-range, low-interference environments up to 1000mW for maximum range and penetration.
• Laju pakét: Select the desired packet rate (e.g., 50Hz, 100Hz, 250Hz, 500Hz) based on your latency requirements and receiver capabilities. Higher packet rates generally offer lower latency but may consume more power.
• Rasio telemétri: Configure the telemetry ratio to balance between control link robustness and telemetry data rate.
• Binding Status: Monitor the connection status with your receiver.

5.2. Operasi hiber

Once bound and configured, the Aeris Link system provides a reliable control link for your FPV drone. Always perform a range check before flying, especially after changing settings or components. Ensure your drone's flight controller is correctly configured to receive CRSF signals from the ExpressLRS receiver.

6. Pangropéa

• Tetep Bersih: Regularly clean the module's exterior with a soft, dry cloth. Avoid using harsh chemicals or solvents.
• Perawatan Antenna: Ensure antennas are not bent or damaged. A damaged antenna can significantly reduce range and signal quality.
• Pembaruan firmware: Keep your module's firmware updated to the latest version to benefit from performance improvements and bug fixes.
• Panyimpenan: Store the module in a dry, cool place away from direct sunlight and extreme temperatures.

7. Cara ngungkulan

7.1. No Link/Binding Issues

• Check Binding Phrase: Ensure the binding phrase on both the TX module and receiver is identical.
• Firmware Mismatch: Verify that both the TX module and receiver are running compatible firmware versions. Update if necessary.
• Sasayogian tanaga: Confirm the TX module and receiver are receiving adequate power. For TX modules, consider using external XT30 power if experiencing instability.
• Sambungan Antenna: Ensure antennas are securely connected to both the TX module and receiver.

7.2. Reduced Range or Signal Loss

• Daya kaluaran: Increase the output power setting on your TX module via the OLED screen or Lua script.
• Orientasi anteneu: Optimize the orientation of your TX and receiver antennas for best signal reception.
• gangguan: Fly in areas with minimal RF interference. Avoid flying near large metal objects, power lines, or Wi-Fi hotspots.
• Pita frékuénsi: If experiencing issues in a 2.4GHz environment, consider using a 915MHz system for potentially better penetration and range, if permitted in your region.

7.3. Compatibility with Radio Transmitters

The EMAX Aeris Link TX module is designed for radio transmitters with a JR module bay and support for OpenTX or EdgeTX firmware. It supports the Crossfire Serial Data Protocol (CRSF). If your radio does not meet these specifications, compatibility may be limited. For example, older FrSky radios like the X9 Lite may require specific firmware or external adapters to function correctly with ExpressLRS modules.

8. Tips pamaké

• Pilihan Frékuénsi: Choose your frequency band (2.4GHz or 915MHz) based on your local regulations and flying environment. 915MHz generally offers better range and penetration, while 2.4GHz is more common globally.
• Manajemén kakuatan: For high output power settings (e.g., 500mW or 1000mW), always use the XT30 external power input on the TX module to ensure stable operation and prevent your radio's internal power supply from being overloaded.
• Rojongan Komunitas: ExpressLRS has a large and active community. If you encounter complex issues, consult online forums and community groups for assistance.
