What to do if Hesai OT128 Radar motor is running but no output data is received?
- M

  To resolve this issue, ensure the Ethernet cable is properly connected. Verify that the destination IP is correctly set using LidarUtilities or PTC commands. Also, confirm that the horizontal FOV is properly set using the same tools. Check that the sensor version firmware is correct, which can be queried via LidarUtilities or PTC commands. Ensure the lidar is emitting laser light, which can be checked with an infrared camera, sensor card, or phone camera without an infrared filter. If a connection box is in use, try replacing the Ethernet cable with a Cat 6 or higher cable. Power cycle the device to see if the problem persists.

What to do if I can receive data on Wireshark but not on PandarView 2 with Hesai OT128?
- J

  To address this, ensure the Lidar Destination Port is correctly configured using LidarUtilities or PTC commands. Verify that your PC's firewall is disabled or that PandarView 2 is added as an exception. If VLAN is enabled, ensure the PC's VLAN ID matches the lidar's, which can be checked using LidarUtilities or PTC commands. Also, make sure you have the latest version of PandarView 2 installed. Power cycle the device to see if the problem persists.

Why is the packet size abnormal (missing packets) on my Hesai OT128?
- S
  Sandra ReedAug 23, 2025
  To resolve this issue, ensure the azimuth FOV is properly set using LidarUtilities or PTC commands. Verify that the spin rate is steady, which can be queried using the same tools. Check that the Ethernet is not overloaded and that no switch is connected to the network. Connect the PC directly to the lidar to check for packet loss. Power cycle the device to see if the problem persists.

  To resolve this, ensure the power adapter is properly connected and in good condition. If a connection box is used, make sure it is intact. Verify that the input voltage and current meet the specified requirements. Also, ensure the lidar is not in standby mode, which can be checked using LidarUtilities or PTC commands. Power cycle the device to see if the problem persists.

What causes abnormal point cloud (misaligned, flashing, incomplete FOV) on Hesai Radar?
- S
  Samantha WillisAug 28, 2025
  To correct this, ensure the lidar's cover lens is clean. Verify that the lidar's angle correction file is imported. Make sure the azimuth FOV is properly set using LidarUtilities or PTC commands and that the spin rate is steady, which can be queried using the same tools. Check for packet loss. If no packets are missing and the point cloud flashes, update PandarView 2 to the latest version and restart the PC. If the issue persists, connect the lidar to another PC and power cycle the device.

  If you're not receiving output data, verify the following: Ensure the Ethernet cable is properly connected. Confirm that the Destination IP and Azimuth FOV are correctly set, and the Firmware of Sensor Version is correct. Check that the Hesai Radar is emitting laser light, and if using a connection box, try replacing the Ethernet cable with at least a Cat 6 cable (Cat 7 or higher is recommended). Afterward, power cycle the Radar to see if the issue persists.

  David ParksSep 4, 2025
  If the point cloud appears abnormal, ensure the following: Clean the lidar's cover lens. Import the lidar's angle correction file. Verify that the Azimuth FOV is properly set and the Spin Rate is steady. Also, check for packet loss. If the point cloud flashes, update PandarView 2 to the latest version and restart your PC. If problems persist, connect the lidar to another PC and network, then power cycle the device.

What to do if Hesai Radar output data can be received by Wireshark but not by PandarView 2?
- M
  Mandy StevensSep 6, 2025
  If you can receive data via Wireshark but not PandarView 2, check these items: If VLAN is enabled, ensure your PC's VLAN ID matches the lidar's. Disable your PC's firewall or add PandarView 2 to the firewall exceptions. Make sure you have the latest version of PandarView 2 installed. Finally, power cycle the lidar and check if the symptom persists.

Why is Hesai OT128 Radar not connecting to LidarUtilities?
- C
  Caitlin SmithSep 9, 2025
  If the lidar isn't connecting to LidarUtilities, verify that the Ethernet cable is properly connected. Ensure the lidar's IP address is in the same subnet as your PC's. If VLAN is enabled, confirm that the PC's VLAN ID matches the lidar's. If issues persist, restart your PC or try connecting the lidar to another PC, then power cycle the lidar.
