Why do I experience data dropouts with my Velodyne VLS-128?
- B
  Benjamin GentryAug 2, 2025
  Data dropouts with Velodyne Accessories are often related to network or computer issues. Consider these potential causes and solutions: * Ensure the sensor's horizontal field of view is not set to less than 360°. * Reduce excessive network traffic or collisions. * Verify that no network device is throttling traffic, as wireless access points often throttle broadcast data. * Check for excessive broadcast packets from other services that might slow down the sensor. * Confirm your computer can handle the packet flow from the sensor. For testing purposes, try connecting the computer directly to the sensor, bypassing other network devices.

  If you're unable to access the sensor's web interface for your Velodyne Accessories, check the following: * Ensure the Ethernet wiring is working correctly. * Verify packet output using another application like VeloView or Wireshark. * Check your computer's network settings, including the static IP address. * Make sure no security software is blocking Ethernet broadcasts. As a solution, reboot your computer, because sometimes network settings require a reboot to take effect.

  Jason JohnstonAug 15, 2025
  If the GPS is not synchronizing with your Velodyne Accessories, check these items: * Verify the baud rate is set to 9600 and the serial port is set to 8N1 (8 bits, no parity, 1 stop bit). * Check the electrical continuity of PPS and serial wiring. * Ensure correct construction of the NMEA sentence. * Verify the signal levels: “High” voltage must be greater than 3.0 V and less than 15.0 V; “Low” voltage must be less than 1.2 V. * Confirm the serial line is sourcing enough current: the GPS/INS unit must source at least 2 mA in the “high” voltage state. * Check the polarity of the serial and PPS signals. * Ensure the GPS signal isn't obstructed (e.g., indoors, near buildings, trees). Move the receiver to an open area for better reception.

What to do if I can see data in Wireshark but not VeloView with Velodyne VLS-128?
- M
  Michael JacksonSep 12, 2025
  If you can see data in Wireshark but not in VeloView with your Velodyne Accessories, it might be due to firewall settings. Wireshark captures packets promiscuously, while VeloView requires permission to receive packets through the system firewall. Check if a firewall is active on the receiving computer and ensure VeloView is allowed to receive data through it.
