5. Konfigurazioa

5.1 Moduluaren instalazioa

The ES24TX Pro module is designed for plug-and-play installation into radio transmitters equipped with a Micro JR bay. Ensure your radio transmitter supports external modules via a JR bay.

1. Power off your radio transmitter.
2. Carefully insert the ES24TX Pro module into the Micro JR bay on the back of your radio transmitter. Ensure it is seated firmly.
3. Connect the provided Moxon antenna to the SMA connector on the module. Hand-tighten the connector; do not overtighten.

5.2 Firmwarea eta konfigurazioa

The ES24TX Pro module comes pre-assembled and ready for use. For optimal performance and access to the latest features, it is recommended to keep the module's firmware updated. Refer to the official ExpressLRS documentation for detailed instructions on firmware flashing and configuration via the ExpressLRS Configurator.

This module supports most OpenTX radio transmitters. Ensure your radio's internal RF module is disabled and the external module is set to CRSF protocol in your radio's model settings for proper communication.

6. Funtzionamendua

6.1 Piztu/Itzali

The module powers on and off with your radio transmitter. Once powered on, the RGB LED will indicate its status (e.g., binding mode, connected, error).

6.2 Hartzailearekin lotura

To establish a connection between the ES24TX Pro module and an ExpressLRS receiver, follow the standard ExpressLRS binding procedure. This typically involves putting both the TX module and the receiver into binding mode (often by powering the receiver on/off three times or using a bind button) and then initiating the bind process from your radio's ExpressLRS LUA script or menu.

6.3 RF Output Power Settings

The ES24TX Pro module supports a maximum RF output power of up to 1000mW (>30dBm). The output power can be adjusted via the ExpressLRS LUA script on your OpenTX radio. Always select an appropriate power level for your flying environment and local regulations. Higher power levels generate more heat, which the integrated cooling fan is designed to manage.

7. Mantentzea

7.1 Hozte haizagailua

The ES24TX Pro includes a cooling fan to dissipate heat generated during operation, especially at higher RF output power settings. Periodically check the fan for any obstructions (dust, debris) and ensure it spins freely. Clean gently with compressed air if necessary.

7.2 RGB LED

The RGB LED provides visual feedback on the module's status. No specific maintenance is required for the LED, but familiarize yourself with its color codes as defined by the ExpressLRS firmware for troubleshooting and operational awareness.

8. Arazoak

• Module Not Recognized by Radio: Ensure the module is fully seated in the JR bay. Verify that the radio's internal RF module is disabled and the external module is set to CRSF protocol in the radio's model settings.
• Lotura arazoak: Confirm both the TX module and receiver are running compatible ExpressLRS firmware versions. Double-check the binding procedure as per ExpressLRS documentation.
• Intermittent Connection/Low Range: Check the antenna connection on both the TX module and receiver. Ensure the antenna is not damaged or obstructed. Verify RF output power settings are appropriate.
• Gehiegizko berotzea: Ensure the cooling fan is operational and free from obstructions. Reduce RF output power if operating in a confined space or high ambient temperature.
• Physical Fit Issues: Some radio transmitter JR bays may have slight variations. If the module does not fit perfectly, do not force it. Consult your radio's manual or community forums for known compatibility issues or minor modifications.
