4.2. Connection Steps

1. Connect to Transceiver:
   • For Xiegu G90/G106: Connect the supplied CIV cable (3.5mm to 3.5mm) from the DE-19's 'CIV' port to the 'CIV' port on your G90/G106 transceiver.
   • For Xiegu XPA125B: Connect the supplied ACC cable (8-pin mini-DIN to 3.5mm) from the DE-19's 'ACC' port to the 'ACC' port on your XPA125B amplifier.
   • For audio input/output (e.g., for digital modes), connect the appropriate audio cables (not always included, may require separate purchase) from your transceiver's audio out/in ports to the corresponding audio input/output on the DE-19 (if available and required for your specific setup). The DE-19 primarily handles CAT and PTT.
2. Connect to PC: Connect the supplied USB cable from the DE-19's 'USB' port to an available USB port on your computer.
3. Power On: Ensure your transceiver and computer are powered on. The DE-19 draws power directly from the USB connection.

4.3. Driver Installation

Upon connecting the DE-19 to your computer via USB, the necessary drivers (typically for a virtual COM port and USB audio device) should install automatically on most modern operating systems (Windows 10/11, macOS, Linux). If automatic installation fails, please visit the official Xiegu website (www.xiegu.eu or www.radioddity.com/collections/xiegu for Radioddity distribution) to download and manually install the latest drivers for the DE-19.

5. Operating Instructions

Once the DE-19 is physically connected and drivers are installed, you can begin using it with your PC software.

5.1. LED Indicators

• USB Activity LEDs (3 LEDs): These indicators illuminate to show data transmission and reception activity over the USB connection. A blinking light indicates active data flow.
• ON AIR LED: This LED illuminates when the transceiver is transmitting (PTT activated).
• ON LINE LED: This LED indicates that the DE-19 is powered on and communicating with the connected transceiver.

5.2. Software Configuration

The DE-19 provides a virtual COM port for CAT control and a USB audio device for digital mode sound card functionality. You will need to configure your amateur radio software (e.g., WSJT-X, FLdigi, Ham Radio Deluxe, etc.) to use these interfaces:

1. Identify COM Port: In your computer's Device Manager (Windows) or System Information (macOS/Linux), locate the newly installed virtual COM port associated with the DE-19. Note its COM port number.
2. Identify Audio Device: Similarly, identify the USB audio device (often named something like 'USB Audio CODEC') provided by the DE-19.
3. Configure CAT Control: In your radio control software, select the identified COM port for CAT control and set the baud rate to match your transceiver's settings (refer to your transceiver's manual).
4. Configure PTT: PTT (Push-To-Talk) can typically be configured via CAT commands or DTR/RTS lines on the virtual COM port. Select the appropriate method in your software.
5. Configure Audio: In your digital mode software, select the DE-19's USB audio device for both input (receive) and output (transmit) audio. Adjust audio levels within the software and your operating system for optimal performance.

6. Maintenance

To ensure the longevity and optimal performance of your Xiegu DE-19, follow these simple maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the exterior of the unit. Avoid using harsh chemicals, solvents, or abrasive materials.
• Storage: When not in use for extended periods, store the DE-19 in a cool, dry place, away from direct sunlight and extreme temperatures.
• Connections: Periodically check all cable connections to ensure they are secure and free from damage. Avoid bending cables sharply or putting strain on the connectors.
• Environment: Operate the DE-19 in a stable environment, free from excessive dust, moisture, or vibrations.
