1.3 Terms and Abbreviations

Terms and abbreviations IP MDOP DCSP DSOP
*.pcd
*.csv
*.pcap

Meaning
The IP address of the network protocol used by the LiDAR communication Primary data transfer port Device control command transmission port The port where the device status information is transmitted A file format in which the GUI saves point cloud data, which can be directly read and played back by the GUI The GUI saves a file with this format for point cloud data, which can be viewed directly in Excel or Word A file format in which the GUI saves point cloud data, which can be directly read and played back by the GUI.
Table. 1: Terms and abbreviations

1.4 Precautions before use
1.Before using the LiDAR, you need to change the IP address of your computer.
Network and Internet Ethernet Change adapter options Properties Internet Protocol version 4 (TCP/IPv4), set the host IP address to remain on the same network segment as the LiDAR IP address (i.e., segment 0), subnet mask 255.255.255.0, and host IP address used in this instruction manual is 192.168.0.10 (the last byte is different from the IP address of the connected device).
Figure. 1: Configuring IP address 1.Make sure that your computer's firewall is turned off (this is optional: if
you can't connect properly, try this step again). Control Panel System and Security Windows Defender Turn on/off Windows Defender Firewall.
