6 Communication Protocol
The communication between RS-Helios-1615 and computer is through Ethernet and by sending
UDP packets. There are mainly two types of communication protocols, as shown in the following
table:

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-1615 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:
