Setup Instructions
1. Driver Installation
When the cable is connected to a PC, the necessary drivers typically install automatically. If automatic installation does not occur, manual driver installation is required.
- Download the appropriate driver from the official Prolific website: PL23XX_Pro-lific_DriverInstaller_v408.zip.
- Run the downloaded installer and follow the on-screen prompts to complete the driver installation.
- After successful installation, open your computer's Device Manager. Locate the "Ports (COM & LPT)" section to identify the newly created virtual COM port. Note down the assigned COM Port Number (e.g., COM3, COM4). This number will be required for the update software.

Operating Instructions
This cable supports two primary methods for updating your GTMedia satellite receiver: direct firmware burning via USB and TFTP update via network.
Method 1: Firmware Burning (USB)
This method is typically used when the satellite receiver is unable to boot normally.
- Prepare Firmware: Download the specific firmware file for your GTMedia receiver model. Ensure the file is named flash.bin and place it in the root directory of a USB flash drive.
- Connect USB Drive: Insert the prepared USB flash drive into the USB port of your GTMedia satellite receiver.
- Connect Serial Cable: Connect the 3.5mm plug of the LINGQE cable to the serial port (often labeled RS232 or Service) on your GTMedia receiver. Connect the USB-A end of the cable to your computer.
- Launch Update Software: Open the appropriate update software on your computer (e.g., a specific loader tool provided by GTMedia or a generic RS232 update utility).
- Configure Software: In the update software, select the correct COM Port Number identified during driver installation. Choose the appropriate platform or device model.
- Initiate Update: Click "OK" or the equivalent button to start the update process. The software will prompt you to restart the satellite receiver.
- Restart Receiver: Power cycle your GTMedia receiver (turn it off and then on again). The update process should begin automatically.
Important: Do not disconnect the cable or power off the receiver during the firmware update process to prevent damage.
Method 2: TFTP Update (Network)
This method requires the satellite receiver to be connected to a network.
- Network Connection: Ensure your GTMedia receiver is connected to your local area network (LAN) via an Ethernet cable. Your computer should also be on the same local network.
- Prepare Firmware: Select the firmware file to be updated within the TFTP server software or update utility on your computer.
- Connect Serial Cable: Connect the 3.5mm plug of the LINGQE cable to the serial port on your GTMedia receiver. Connect the USB-A end of the cable to your computer.
- Launch Update Software: Open the TFTP update software on your computer.
- Configure Software: In the update software, select the correct COM Port Number. Choose the appropriate platform or device model.
- Initiate Update: Click "OK" or the equivalent button to start the update process. The software will prompt you to restart the satellite receiver.
- Restart Receiver: Power cycle your GTMedia receiver. The TFTP update process should commence.
Important: Maintain stable network and power connections throughout the TFTP update.

Maintenance
Proper care and maintenance will extend the lifespan of your LINGQE USB to RS232 Serial Update Cable.
- Storage: Store the cable in a cool, dry place away from direct sunlight and extreme temperatures. Avoid tightly coiling the cable to prevent internal wire damage.
- Cleaning: Use a soft, dry cloth to gently wipe the cable and connectors. Do not use liquid cleaners or solvents, as these can damage the insulation or electronic components.
- Handling: Always grasp the connector ends when plugging or unplugging the cable. Avoid pulling on the cable itself, which can strain the connections and lead to breakage.
- Inspection: Periodically inspect the cable for any signs of wear, fraying, or damage to the connectors. Discontinue use if any damage is observed.
Troubleshooting
