6  Communication Protocol 
The communication between RS-Helios-16P and computer is through Ethernet and by sending UDP 
packets. There are mainly two types of communication protocols, as shown in the following table: 
Table 8 Communication Protocols 
Note: The following sections describe and define the valid payload (1248byte) of the protocols. 
1)  The main data stream output protocol MSOP, encapsulates the distance, angle, reflectivity and other 
information measured by the LiDAR into an UDP packet and outputs to the computer; 
2)  Device information output protocol DIFOP, outputs various configuration information of the current state 
LiDAR to the computer; 
6.1  MSOP and DIFOP 
The UDP packet sent by RS-Helios-16P has a payload of 1248 bytes, the data structure of the main 
data stream output protocol (MSOP) and device information output protocol (DIFOP) is as shown 
in the figure below:
