1. About this document
This document summarizes supplementary information on mounting and electrical
installation as well as measured value output format of the LR-1BS2. It is aimed at
sufficiently qualified personnel for the purposes of installation, commissioning and further
data processing. Notes on commissioning, configuration and maintenance can be found in the
LR-1BS2 operating instructions
2. Safety information
Read the notes on mounting and electrical installation before carrying out these tasks.;
Read additionally the LR-1BS2 operating instructions to familiarize yourself with the
device and its functions;
The LR-1BS2 complies with laser class 1.
Only use the device in permissible ambient conditions (e.g. temperature, ground
potential). Any applicable legal regulations or regulations of other authorities will have to
be observed during operation.
Opening the screws of the LiDAR housing will invalidate any warranty claims against
OLEI.
Repairs may only be performed on the LiDAR by trained and authorized OLEI service
personnel
3. Product introduction
The LR-1BS2 is an opto-electronic laser scanner that electro-sensitively scans the
perimeter of its surroundings at a single plane with the aid of laser beams. The LR-1BS2
measures its surroundings using two-dimensional polar coordinates based on its measurement
origin. It can output both point cloud data output and safety signal (I/O port).
Thus LR-1BS2 has been widely applied to industries such as robot obstacle avoidance,
safety monitoring, industrial automation, and intelligent logistics.
4. Installation and operation
4.1. Mechanical interface
The LiDAR can be installed in two ways: back-mounted and bottom-mounted.
Back-mounted
There are two M3 screw holes (hole depth is 3mm) at the back of the LiDAR.

4.3. Communication interface
The LR-1BS2 is connected to the computer by a RJ-45 Ethernet interface. The computer
IP address should be set up before communication. The LiDAR and computer IP must be set
up in the same subnet without any conflict. The host port is 2368 by default.
The factory default settings are as follows
Computer IP：192.168.1.10
Computer subnet mask：255.255.255.0
The default factory settings of LiDAR are as follows
LiDAR IP：192.168.1.100
LiDAR subnet mask：255.255.255.0
The operation steps are as follows

5. Measurement principle
Figure 8 Diagram of LR-1BS2 LiDAR work principle
As is shown in the figure above, LR-1BS2 measures distance by using the time-of-flight
principle. The LiDAR emits pulsed laser beams using a laser diode. If one of these laser
pulses hits an object or a person, this is reflected at its surface. The reflection is detected in
the LiDAR's receiver by a photodiode. The LiDAR calculates the distance to the object from
the transit time required by the light from emission of the beam to receipt of the reflection.
The calculation method is as follows:
𝐷 = 𝐶𝑇
2
D —Detection range
T —Flight time
C —Speed of light
6. Parameter configuration
6.1. Parameter configuration of web page
Web page parameter configuration method of LR-1BS2 is as follows:
Open the browser (please use Chrome,Firefox, Edge or other standard browsers),
and enter the LiDAR IP address;
"Model" and "Version" at the top of the UI indicate the product model and
firmware version;
"Temperature", "Voltage" and "SafeArea" on the right side of the UI are the
LiDAR parameters displayed in real time, indicating the temperature, voltage and
current active Bank. When the font color of parameter turns red, please check
whether the LiDAR is malfunctioning;
Automatically read the current settings of LiDAR by refreshing the page;
Select the desired speed through "Motor RPM": 600/900/1200/1500
