2 LGS-N25

CHAPTER 3 WORKING PRINCIPLES
The LGS-N25 is a 2D LiDAR that scans the surrounding area in a single plane with the help of an infrared invisible laser beam. The LGS-N25 uses 2D polar coordinates to characterize the surrounding environment based on its measurement origin. With a scanning angle range of 360°, the LGS-N25 can detect and output information of the angle, distance and signal strength of the target, which facilitating better target identification by SLAM systems.
Figure 1 - LGS-N25 working principle
USER MANUAL 3

WORKING PRINCIPLES
Figure 2 The LGS-N25 measurement principle is shown in the figure above, and it uses the timeof-flight principle to measure distance. LiDAR emits laser pulses at uniform and very short intervals, and the laser light is reflected back when it encounters an obstacle. The LiDAR receives the reflected light signal and calculates the distance information between the object and the LiDAR based on the time difference (i.e., the time of flight of the laser) T between the emission and reception and the speed of light C. The calculation method is shown below.
D=c*T/2 Where: D = distance T = flying time c = speed of light

CHAPTER 4 INSTALLATION AND USAGE
MECHANICAL CONNECTION
The LGS-N25 LiDAR can be mounted thanks to the four M3 screw holes located on the bottom side of the device, we suggest to use M3 x 8 screws.

INSTALLATION AND USAGE
ELECTRICAL CONNECTION
The LGS-N25 has 2 pig tail connectors, a 4-pole M12 male connector for power supply and a 4-pole M12 D-coded female connector for Ethernet communication. As shown in the figure below.

COMMUNICATION

Figure 4 - Ethernet connector
COMMUNICATION
The standard Ethernet RJ-45 connector is used to connect the LGS-N25 to the computer. The computer IP address needs to be set before communication, the first three segments of the computer IP address must be set the same as the LiDAR (192.168.1.X) and be in the same subnet. The last segment of the computer IP cannot be set to 100 to prevent conflict with the LiDAR default IP. Port number of the point cloud packet is 2368
The default factory settings for LiDAR are shown below: · LiDAR IP:192.168.1.100 · LiDAR subnet mask: 255.255.255.0
The recommended computer IP settings are shown below: · Computer IP: 192.168.1.10 · Computer subnet mask: 255.255.255.0

CHAPTER 9 TROUBLESHOOTING

PROBLEM
LiDAR fails to scan
LiDAR scan produces no data

SOLUTION
· Check power connection · Check whether voltage meets 9 to 30 VDC If failure persists, contact Datasensing Technical Support. · Check net connection · Check the IP setting of the data receiver · Try to use a third-party data capture tool to check
whether data can be obtained normally · Check if only one LiDAR software is started · Verify that the firewall on the receiving end of the data
is turned off, or that there is no other security software or process blocking data transmission. If failure persists, contact Datasensing Technical Support.

APPENDIX C RECOMMENDATIONS FOR MECHANICAL INSTALLATION
1. Protect the product respect to high shock and vibration source. 2. Do not expose it to any direct sunlight (windows, skylights) or any other heat
source in order to keep the temperature as the standard profile 3. It is recommended that the installation base used to fix the LiDAR be as flat as pos-
sible without any unevenness. 4. The positioning posts on the installation base should strictly follow the depth of
the positioning posts at the bottom of the LiDAR. The height of the positioning posts should not be higher than 4mm. The material of the mounting base is recommended to be aluminum alloy or similar metallic material. 5. When installing the LiDAR, if there are contact mounting surfaces above and below the LiDAR, please ensure that the distance between the mounting surfaces is greater than the height of the LiDAR to avoid damaging to his parts. 6. When installing and wiring the LiDAR, do not pull excessively the wires and keep it a bit loose. 7. In order to avoid any impact on measurement accuracy due to mutual interference between LiDARs, we recommend installation as shown below

Cleaning method
If there is only some dust adhered to the surface of the radar, you can directly use the clean fiber cloth 95ASE3000 with a small amount of anti-static alcohol free solution 95ASE2990 to gently wipe the surface of the window LiDAR, and then wipe it dry with a dry and clean fiber cloth.
If the surface of liDAR's optical window is stained with lumps of foreign matter such as mud, clean water should first be sprayed on the surface of the dirty parts to remove the mud and other foreign matter.

CAUTION

Do not wipe off the mud directly with a fiber cloth, as this may scratch the surface irreparably).

If the first operation result not effective, secondly, spray warm water, with eventually mild soap, on the dirty area.

The lubricating effect of soapy water can accelerate the removal of foreign matter.

Gently try to wipe the surface of the liDAR with the fiber cloth again, but be careful not to scratch the window surface.

Finally, clean the soap residue on the liDAR surface with clean water (if there is still residue on the surface clean it again with anti-static alcohol free solution), and wipe it dry with a dry microfiber cloth
