Introduction

The RoboSense E1R represents a high-performance solid-state LiDAR solution employing Flash scanning technology with an impressive 120° × 90° ultra-wide field of view. For beginners acquiring this sensor, the critical first step involves connecting it to a computer and successfully visualizing the point cloud data.

This comprehensive guide walks you through every minute detail—from hardware wiring to software display—addressing common pitfalls such as "successful ping but no visual output" and "blinking green lights."

Section 1: Hardware Preparation

Before beginning the connection process, ensure you have the following components readily available:

Required Hardware:

  • RoboSense E1R LiDAR sensor unit
  • Interface Box: Since the LiDAR utilizes automotive Ethernet connectors, an interface box is essential for conversion to standard RJ45 Ethernet ports
  • Power Adapter: Voltage requirements span 9V–16V (12V 2A DC power supply recommended, standard DC 5.5-2.1mm connector)
  • Ethernet Cable: Category 5e or Category 6 cable
  • Windows Computer: Windows 10 or Windows 11 recommended
  • Additional necessary wiring (typically provided by the manufacturer)

Section 2: Physical Connection Procedure

Follow this connection sequence to protect sensitive electronic components:

Step-by-Step Connection:

  1. LiDAR Connection: Insert the LiDAR's proprietary large TE curved plug into the corresponding interface box port. Ensure firm seating.
  2. Network Connection: Connect the interface box's RJ45 Ethernet port to your computer's Ethernet port using the network cable.
  3. Power Connection: Finally, connect the power adapter.

Observation: The green indicator light on the interface box should illuminate.

Important Note: If the green light blinks, this typically indicates the LiDAR is transmitting high-frequency data—this represents normal operation.

Section 3: Computer Network Configuration (Critical Step)

Successful communication between the LiDAR and computer requires both devices to operate within the same network segment with matching IP addresses.

LiDAR Default Configuration:

  • LiDAR Static IP: 192.168.1.200
  • LiDAR Target IP: 192.168.1.102 (The LiDAR defaults to sending data exclusively to this address)

Configuring Your Computer's IP Address:

  1. Open: Control Panel → Network and Sharing Center → Change Adapter Settings
  2. Right-click your Ethernet adapter and select Properties
  3. Double-click "Internet Protocol Version 4 (TCP/IPv4)"

  4. Select "Use the following IP address" and enter:

    • IP Address: 192.168.1.102 (This exact address is mandatory)
    • Subnet Mask: 255.255.255.0
  5. Click OK to save configuration

Section 4: Connectivity Verification (Ping Test)

Before launching visualization software, verify physical link connectivity:

Testing Procedure:

  1. Press Windows + R, type cmd, and press Enter
  2. Enter the command: ping 192.168.1.200

  3. Result Interpretation:

    • Success: Displays "Reply from 192.168.1.200"
    • Failure: Displays "Request timed out"—check network cable and computer IP configuration

Expected Successful Output:

C:\Users\User>ping 192.168.1.200

Pinging 192.168.1.200 with 32 bytes of data:
Reply from 192.168.1.200: bytes=32 time=1ms TTL=255
Reply from 192.168.1.200: bytes=32 time<1ms TTL=255
Reply from 192.168.1.200: bytes=32 time=3ms TTL=255
Reply from 192.168.1.200: bytes=32 time<1ms TTL=255

Ping statistics for 192.168.1.200:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss)
Approximate round trip times in milliseconds:
    Minimum = 0ms, Maximum = 3ms, Average = 1ms

Section 5: Environment Cleanup (Firewall Configuration)

This step resolves 90% of point cloud reception failures: Windows Firewall may block UDP data packets.

Disabling Windows Firewall:

  1. Navigate to: Control Panel → System and Security → Windows Defender Firewall
  2. Click "Turn Windows Defender Firewall on or off" in the left panel
  3. Select "Turn off Windows Defender Firewall" for both Private and Public network settings
  4. Click OK to apply

Important: You may re-enable the firewall after testing completes, but it must remain disabled during LiDAR debugging.

Section 6: Visualization Using RSView Software

Software Setup:

  1. Download: Obtain the latest RSView version from the RoboSense Official Resource Center
  2. Extraction Warning: The extraction path must not contain any Chinese characters, or the software will fail to launch or produce errors
  3. Launch: Double-click RSView.exe to run

  4. Stream Configuration:

    • Configure the stream settings according to your LiDAR model
    • Click OK to initiate data reception
  5. Expected Result: You should observe a colorful point cloud display within the black 3D grid space. Use your mouse left button to rotate the viewing angle and the scroll wheel to zoom.

Section 7: Troubleshooting Common Issues

Problem: Ping Succeeds, But RSView Shows Black Screen

Solution: Verify two critical items:

  1. Computer IP must be exactly 192.168.1.102
  2. Firewall must be completely disabled

Problem: Interface Box Green Light Continuously Blinking—Normal?

Answer: Yes, this is normal. Blinking typically indicates the LiDAR is continuously transmitting UDP point cloud data packets at 10Hz frequency.

Problem: LiDAR Housing Becomes Very Hot

Answer: The E1R is a high-power solid-state LiDAR—heat generation during operation is expected. Avoid prolonged operation in enclosed, poorly ventilated environments, and minimize direct hand contact during operation.

Section 8: Experiment Conclusion and Maintenance

Proper Shutdown Sequence:

  1. First disconnect the DC power from the interface box
  2. Then close the software
  3. Avoid frequent plugging/unplugging of the LiDAR's TE connector while powered

Cleaning Procedures:

If the optical window develops fingerprints, use a lint-free cloth lightly dampened with alcohol for gentle cleaning. Never use dry paper towels, as they may scratch the optical coating.

Final Thoughts

This tutorial provides a complete pathway from unboxing to successful point cloud visualization with the RoboSense E1R LiDAR. The key to success lies in meticulous attention to network configuration and firewall settings—these represent the most common failure points.

Remember: systematic troubleshooting, starting from physical connections and progressing through network configuration to software settings, will resolve most issues efficiently.
