Congratulations on your purchase of a V elodyne HDL-64E S2 or S2.1 High Definition LiDAR Sensor. These sensors represent a breakthrough in sensing technology by providing more information about the surrounding environment than previously possible. The HDL-64E S2 or S2.
The sensor operates, instead of a single laser firing through a rotating mirror, with 64 lasers fixed mounted on upper and lower laser blocks, each housing 32 lasers.

W iring The sensor comes with a pre-wired connector , wired with power , DB9 serial and standard RJ45 Ethernet connectors. The connector wires are approximately 10’ [3 meters] in length. Power . Connect the red and black wires to vehicle power . Be sure red is positive polarity .
The following provides more detail on each of the above steps. 1. Establish communication with the sensor. The sensor broadcasts UDP packets. By using a network monitoring tool, such as Wireshark, you can capture and observe the packets as they are generated by the sensor .
3. Parse the packets for rotation, block, distance and intensity data. Each sensor ’s LIFO data packet has a 1206 byte payload consisting of 12 blocks of 100 byte firing data followed by 6 bytes of calibration and other information pertaining to the sensor.

Packet Format and Status Byte for GPS T ime Stamping The 6 bytes at the end of the data packet report GPS timing and synchronization data. For every packet, the last 6 bytes are formatted as follows: Timestamp Bytes in Reverse Order in Microseconds Bytes Description Notes 4 GPS timestamp 32 bit unsigned integer timestamp.
Lasers are numbered sequentially starting with 0 for the first lower block laser to 31 for the last lower block laser; and 32 for the first upper block laser to 63 for the last upper block laser. For example, laser 32 fires simultaneously with laser 0, laser 33 fires with laser 1, and so on.

Digital Sensor Recorder (DSR) DSR is a 3D point-cloud visualization software program designed for use with the sensor. This software is an “out of the box” tool for the rendering and recording of point cloud data from the HDL unit. Y ou can develop visualization software using the DSR as a reference platform.
Record Data 1. Confirm the input of streaming data through the live playback feature. 2. Click the Record button . RECORD button = 5. Enter the name and location for the pcap file to be created. 6. Recording begins immediately once the file information has been entered.

HDL-64E Ethernet Timing T able Overview The Ethernet Timing T able shows how much time elapses between the actual capturing of a point’s data event and when that point is an event output from the sensor .
How to use this table The table represents a sensor data packet. The laser returns come out in the order listed. Simply subtract from the timestamp of the output event of the packet each data value to arrive at the actual time the distance point was captured inside the sensor.
