Page 7: Working Principles
CHAPTER 3 WORKING PRINCIPLES LGS-N50 is a 2D LiDAR sensor developed to meet the needs of Object Localization. The output of this product is point cloud data (Ethernet port). A laser beam emitted from LGS-N50 internal laser diode is projected around LiDAR through a rotating mirror and then returns (the amount of returned laser energy depends on the reflectivity of objects). -
Page 8: Installation And Usage
CHAPTER 4 INSTALLATION AND USAGE MECHANICAL CONNECTION LGS-N50 LiDAR can be installed in two ways: back mounting and base mounting. Back mounting There are four M5 screw holes at the back of the main frame for installation (hole depth: 8mm). -
Page 9: Base Mounting
There are three M5 screw holes at the base of the main frame for installation (hole depth: 8mm). Figure 3 - LGS-N50 Base Mounting interface ELECTRICAL CONNECTION There are three connectors on the back of LGS-N50 for power supply, I/O and 4PIN Ethernet connection respectively as shown below: Figure 4 - LGS-N50 Connection USER MANUAL... -

Figure 7 - Ethernet connector COMMUNICATION The LGS-N50 is connected to the computer through a standard Ethernet RJ-45 connec- tor. The computer IP address must be set prior to establishing communication. Both the LiDAR and the computer IP addresses must be set within the same subnet without con- flicting with each other. - Page 12 INSTALLATION AND USAGE Figure 9 - Computer IP Setting: Step 2 Figure 10 - Computer IP Setting: Step 3 LGS-N50 Preliminary 13-Jan-2021...

LEDS LEDs Figure 11 - LGS-N50 LEDs MEANING Shows the status of powered devices (off = no power; on = powered) Shows the status of “out of temperature range” (Tenvironment < Tmin or Tenvironment > Tmax). In such a case, Q1 blinks and the “ERR” LED lights up steadily. -
Page 14: Data Packet Format
CHAPTER 5 DATA PACKET FORMAT Information transmission between LGS-N50 and computer follows UDP/IP standard net- work protocol. The data adapts Little-endian format with low byte at the front and high byte at the end. OVERVIEW Total length of data packet is 1240 bytes, among which the header has 40 bytes, data returned by laser has 1200 bytes. -
Page 15: Definition Of Header
DEFINITION OF HEADER DEFINITION OF HEADER Total length of data packet is 1240 bytes, among which 40 bytes represent the header, and 1200 bytes represent the data returned by laser. OFFSET LENGTH DESCRIPTION ID, it is always 0xFEF0010F Protocol version code, the current code is 0x0200 Distance scale, actual distance = readout data x distance scale (mm) Brand name code. -
