5. Setup

Follow these steps for initial setup of your mLRS TX Module KIT:

1. Antenna Connection: Connect the provided IPEX MHF1 adapter cable to the mR24-30 module. Then, attach your 2.4GHz SMA or RP-SMA antenna (not included) to the other end of the adapter cable. Ensure a secure connection.
2. Power Supply: Connect a 5-13V DC power source to the JR_PIN3 (VIN) on the mRx-Tx Adapter. Observe correct polarity.
3. Fan Installation: If operating at RF power levels of 500mW or higher, install the included 5V fan onto the designated fan header on the mRx-Tx Adapter. Use the provided screws for secure mounting.
4. RC Input (CRSF): Connect your RC receiver's CRSF output to the TX2 pin on the mRx-Tx Adapter for control signal input.
5. DFU Mode: To enter DFU (Device Firmware Upgrade) mode, press and hold the "BIND DFU" button while connecting power to the module. Release the button after power is applied.
6. Binding: To initiate the binding process, briefly press the "BIND DFU" button during normal operation. Refer to your mLRS firmware documentation for specific binding procedures.

6. Operating

Once the module is set up, observe the LED indicators for operational status:

• Red and Green LEDs: These LEDs indicate the status of the mLRS system. Refer to the mLRS firmware documentation for specific blink codes and their meanings (e.g., armed, disarmed, failsafe).
• Blue LED: This LED indicates the status of the built-in HC-04 Bluetooth module. A solid blue light typically means Bluetooth is active and ready for connection, while blinking may indicate pairing mode or connection attempts.
• Fan Operation: The 5V fan will automatically activate when the RF output power of the mR24-30 module reaches or exceeds 500mW to ensure adequate cooling.

For detailed configuration and advanced operating modes, consult the official mLRS firmware documentation and associated software tools.

7. Maintenance

The mLRS TX Module KIT is designed for durability, but proper maintenance can extend its lifespan:

• Cleaning: Periodically clean the module with a soft, dry brush or compressed air to remove dust and debris, especially from the fan and heatsink areas.
• Connections: Regularly check all cable connections (antenna, power, RC input) to ensure they are secure and free from damage.
• Firmware Updates: Keep the mLRS firmware updated to the latest version to benefit from performance improvements and bug fixes. Refer to the official Mateksys resources for update procedures.
• Environmental Protection: Store the module in a dry, cool environment when not in use. Avoid exposing it to direct sunlight or extreme temperatures.

8. Troubleshooting

If you encounter issues with your mLRS TX Module KIT, consider the following common problems and solutions:

If the problem persists, consult the official Mateksys support resources or community forums for further assistance.
