6. Device Communication
The device supports either 485 communication or Ethernet communication mode. Only one communication method can be selected between 485 communication or Ethernet communication, and it can be selected according to the needs.
The default baud rate for 485 communication is 115200, and it supports both MODBUS-RTU protocol and our proprietary protocol. The network port supports both MODBUS-RTU protocol and UDP/TCP and HTTP protocols.

9. Introduction to Distance Measurement Mode
1) One to one ranging mode
The 1-on-1 ranging mode is suitable for mechanical positioning that moves in one direction, such as the need to only locate overhead cranes and large vehicles.

2) 1 to many ranging mode
The 1-to-3 ranging mode is suitable for application scenarios where one device needs to measure distances with multiple devices, such as XY positioning of overhead cranes and small cars.

3) Multiple to multiple ranging mode
The many to many distance measurement mode can achieve mutual distance measurement between multiple devices and obtain the distance between them and other devices.
