5. Operating Instructions

Once the YDLIDAR G4 is connected and drivers are installed, you can begin operation using the provided software kit.

• Software Interface: Launch the YDLIDAR G4 software application on your computer.
• Adjusting Parameters:
  • Ranging Frequency: Adjust the frequency at which the lidar collects range data.
  • Scanning Mode: Select different scanning modes based on your application requirements.
  • Low Power Saving Mode: Enable this mode to conserve power when full performance is not required.
• Data Acquisition: Initiate scanning through the software. The G4 will perform 360-degree omnidirectional scans, providing real-time point cloud data.
• Data Processing: Utilize the SDK and API to integrate the collected data into your specific applications, such as SLAM (Simultaneous Localization and Mapping), obstacle avoidance algorithms, or 3D reconstruction.

6. Maintenance

The YDLIDAR G4 is designed for durability and a long operational life. Regular maintenance is minimal but important to ensure optimal performance:

• Cleaning: Keep the optical window and the main body of the lidar clean. Use a soft, dry, lint-free cloth to gently wipe away dust or smudges. Avoid abrasive materials or harsh chemicals.
• Environmental Conditions: Operate the lidar within its specified environmental conditions (temperature, humidity) to prevent damage. While it has an IP54 rating for water resistance, avoid submerging it or exposing it to heavy rain.
• Storage: When not in use, store the YDLIDAR G4 in a cool, dry place, away from direct sunlight and extreme temperatures.
• Cable Care: Ensure the USB Type-C cable is not bent sharply or subjected to excessive strain, which could damage the cable or the port.

7. Troubleshooting

If you encounter issues with your YDLIDAR G4, consider the following common troubleshooting steps:

• No Power/Connection:
  • Ensure the USB Type-C cable is securely connected to both the lidar and the computer.
  • Try a different USB port on your computer.
  • Verify that the USB adapter is functioning correctly.
• Software Not Detecting Lidar:
  • Check if the correct drivers are installed for your operating system. Reinstall them if necessary.
  • Ensure no other applications are using the same serial port as the lidar.
  • Restart your computer and the lidar unit.
• Inaccurate Readings/Interference:
  • Clean the optical window of the lidar.
  • Minimize strong ambient light sources if possible, although the G4 has good interference resistance.
  • Ensure there are no physical obstructions blocking the lidar's scanning path.
• Motor Not Spinning:
  • Verify power connection.
  • Check software settings to ensure the motor is commanded to spin.

For persistent issues, refer to the technical documentation or contact customer support.
