1.2. Mid-360

Note

⚠️1. When connecting the power cable and the function cable, pay attention to their respective voltage ranges and polarities. DO NOT connect any PoE device to the RJ-45 network connector. Incorrect connection can lead to irreversible damage to the LiDAR.

⚠️2. Overlapping with other Lidar FOVs should be avoided. If the laser beams are pointed right at each other, irreversible damage may be caused to the Mid-360.

1.2.2. Supported Time Synchronization Methods

Livox Mid-360 supports 3 time synchronization methods：

PTP：IEEE 1588v2.0 UDP/IP Network protocol synchronization, see details: PTP Time Synchronization；

gPTP: Automotive ethernet time synchronization protocol(2 layer), see details: gPTP Time Synchronization;

GPS: Second pulse + GPRMC time data to form GPS time synchronization mode, see details: GPS Time Synchronization；

Notice:

• The time limit for GPS time synchronization is from 1/1/2000 to 31/12/2037

• PTP time synchronization does not support IEEE1588v2.1

• Not recommended for use in scenarios where IEEE1588v2.0 and gPTP coexist；
