  Hello Hee5760,
  Thank you for your interest in Intel RealSense LiDAR Camera L515.
  Intel RealSense LiDAR Camera L515 is supported to enable Intel RealSense depth camera to be networked over an ethernet connection. You can find more information in this white paper: Open-Source Ethernet Networking for Intel® RealSense™ Depth Cameras
  
  The Intel RealSense LiDAR Camera L515 connector is USB-C 3.1 Gen 1 and the maximum length for USB 3.1 Gen 1 is only 2 meters. We recommend using the USB cable that came in the box with the camera. Regarding using your own choice of cable, it should ideally be a premium grade (industrial grade) cable if a connection longer than 2m is required, otherwise, the camera connection may degrade or fail.  This is due to the high volume of data transmitted through the USB cable by RealSense cameras. RealSense Cameras are very sensitive to USB signaling and cables. 
  
  Many users have found success with this cable from Newnex when they need longer lengths. Newnex provides several options for you to extend the RealSense camera range, either Passive Cable that supports up to 5 m or Active Extension Cable that supports up to 20 m or Fiber Optic Extender that supports up to 300 m.
  Note that Intel only supports the cable that came with the camera and we cannot guarantee the performance of any other cable.

  Thank you for your answer.

  I tried to connect with networked over an ethernet connection with USB-C 3.1 Gen1 cable (recommended cable). However, It is failed.  

   

  I also connected the D435i camera in the same way, and the D435i camera was connected successfully. Nothing has changed. Can I see what's wrong?

   

  Thank you.

   

  Best Regards.

  Hello Hee5716,

  I was able to make it work using librealsense version 2.39 and building from source.

   

  1. After downloading librealsense v2.39, copy the attached CMakeLists.txt and paste it into directory: librealsense/third-party/live555/
  2. cmake ../ -DBUILD_EXAMPLES=true -DCMAKE_BUILD_TYPE=Release -DFORCE_LIBUVC=true -DFORCE_RSUSB_BACKEND=ON -DBUILD_NETWORK_DEVICE=ON
  3. sudo make uninstall && make clean && make && sudo make install

   

  Regards,

  Zulkifli
