Introduction

The RoboSense E1R represents a significant advancement in solid-state LiDAR technology, utilizing Flash scanning methodology to achieve an impressive 120° × 90° ultra-wide field of view. For engineers and enthusiasts beginning their journey with this high-performance sensor, the initial challenge lies in establishing a proper connection to a Windows-based computer and successfully visualizing the point cloud data. This comprehensive guide walks you through every critical step—from physical hardware connections to software configuration—while addressing common pitfalls such as "ping successful but no display" issues and blinking green LED indicators.

Section 1: Hardware Preparation Checklist

Before initiating the connection process, ensure you have all necessary components readily available:

  • RoboSense E1R LiDAR Unit: The main sensor module
  • Interface Box: Essential adapter converting the automotive Ethernet connector to a standard RJ45 port
  • Power Adapter: DC 9V-16V input range (12V 2A recommended, with standard 5.5-2.1mm DC connector)
  • Ethernet Cable: Category 5e or Category 6 network cable
  • Windows Computer: Windows 10 or Windows 11 recommended for optimal compatibility
  • Additional Cabling: All necessary connectors typically provided by the manufacturer

Understanding each component's role is crucial. The interface box serves as the critical bridge between the LiDAR's specialized automotive connector and standard networking equipment, while the power adapter must deliver stable voltage within the specified range to ensure reliable operation.

Section 2: Physical Connection Sequence

Proper connection order protects sensitive electronic components and ensures stable operation:

  1. LiDAR Connection: First, connect the LiDAR's large TE curved plug to the corresponding interface box port. Ensure the connector seats firmly with an audible click.
  2. Network Connection: Next, use the Ethernet cable to connect the interface box's RJ45 port to your computer's Ethernet port.
  3. Power Connection: Finally, connect the power adapter to the interface box.

Observation: Upon power application, the green LED indicator on the interface box should illuminate steadily.

Important Note: A blinking green LED typically indicates normal high-frequency data transmission from the LiDAR, not a fault condition. This visual indicator confirms the sensor is actively transmitting UDP point cloud data packets.

Section 3: Network Configuration (Critical Step)

Successful communication between the LiDAR and computer requires proper network configuration within the same subnet. The LiDAR operates with specific default network parameters:

LiDAR Default Configuration:

  • Static IP Address: 192.168.1.200
  • Target Transmission IP: 192.168.1.102 (the LiDAR exclusively sends data to this address)

Computer IP Configuration Steps:

  1. Navigate to: 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 configure:

    • IP Address: 192.168.1.102 (must be exactly this address)
    • Subnet Mask: 255.255.255.0
    • Default Gateway: Leave blank (not required for direct connection)
  5. Click OK to save settings

This configuration ensures your computer resides in the same subnet as the LiDAR and matches the target address to which the sensor transmits data.

Section 4: Connectivity Verification (Ping Test)

Before launching visualization software, verify physical layer connectivity:

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

  3. Interpreting Results:

    • Success: "Reply from 192.168.1.200" indicates successful connection
    • Failure: "Request timed out" suggests checking cable connections and 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

Zero packet loss confirms proper physical and network layer connectivity.

Section 5: Environment Preparation (Firewall Configuration)

Critical: Windows Firewall represents the most common obstacle preventing point cloud reception, affecting approximately 90% of users experiencing black screen issues in visualization software.

Firewall Disable Procedure:

  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 changes

Important: While firewall can be re-enabled after testing, it must remain disabled during LiDAR debugging to allow UDP data packet reception. For production environments, consider creating specific firewall rules allowing UDP traffic from the LiDAR's IP address.

Section 6: RSView Visualization Software Setup

Software Acquisition: Download the latest RSView version from the official RoboSense Resource Center.

Installation Considerations:

  • Extract the software to a path containing no Chinese characters
  • Chinese characters in the extraction path commonly cause software launch failures or runtime errors
  • Recommended path example: C:\RoboSense\RSView\

Launching and Configuration:

  1. Double-click RSView.exe to launch the application
  2. Configure the data stream settings according to the LiDAR's IP configuration
  3. Click OK to initiate data reception

Expected Result: The 3D visualization window should display a colorful point cloud within the black grid space. Use mouse controls for interaction:

  • Left-click + drag: Rotate viewing angle
  • Scroll wheel: Zoom in/out
  • Right-click + drag: Pan the view

Section 7: Comprehensive Troubleshooting Guide

Problem 1: Ping Successful but RSView Shows Black Screen

Diagnostic Steps:

  1. Verify computer IP is exactly 192.168.1.102 (not 192.168.1.103 or similar)
  2. Confirm Windows Firewall is completely disabled for both network profiles
  3. Check Ethernet cable integrity and connection firmness
  4. Restart RSView application after confirming settings

Problem 2: Interface Box Green LED Blinking Continuously

Assessment: This is normal operation. The blinking indicates the LiDAR is transmitting UDP point cloud data packets at its configured frequency (typically 10Hz). Continuous blinking confirms active data transmission.

Problem 3: LiDAR Housing Becomes Hot to Touch

Explanation: The E1R is a high-power solid-state LiDAR that generates considerable heat during normal operation. This thermal output is expected and does not indicate malfunction.

Recommendations:

  • Avoid operating in enclosed, poorly ventilated environments
  • Minimize direct prolonged hand contact with the housing during operation
  • Consider passive cooling solutions for extended operation periods

Problem 4: Intermittent Connection Loss

Potential Causes:

  • Loose Ethernet cable connections
  • Power adapter voltage instability
  • Network adapter power saving settings

Solutions:

  • Reseat all cable connections
  • Verify power adapter outputs stable 12V
  • Disable Ethernet adapter power saving in Device Manager

Section 8: Proper Shutdown and Maintenance Procedures

Shutdown Sequence:

  1. First, disconnect the DC power from the interface box
  2. Then close the RSView software
  3. Avoid frequently hot-plugging the TE connector at the LiDAR end while powered

Cleaning and Maintenance:

  • For fingerprint or dust removal on the optical window, use lint-free cloth lightly dampened with isopropyl alcohol
  • Never use dry tissue or paper towels, which can scratch the optical coating
  • Store in a dry, dust-free environment when not in use

Long-term Storage:

  • Disconnect all power sources
  • Store in original packaging or anti-static bags
  • Maintain moderate temperature and humidity conditions
