Point to Lora Base Station Application
After user terminal devices form a network via LoRa nodes and the LG210 gateway, the system enables localized zonal management of devices centered around the gateway. This ensures orderly data transmission from multiple nodes without mutual interference, while guaranteeing encrypted data transfer to rapidly achieve end-to-cloud connectivity.
Point to Point/multiple Points Transmission
The USR-LG207 supports point-to-point and point-to-multipoint communication. This device supports various working modes such as data transparent transmission, master-slave mode, fixed-point transmission, and data broadcasting. Users can choose the appropriate mode according to their own needs.
IO Following Application
The USR-LG207 supports I/O linkage, allowing DI inputs to control DO output states. It enables both local and remote wireless linkage.
Long Transmission Distance
Using high-power FEM, the transmission distance can reach up to 8 KM.
LoRa Network Repeater
The USR-LG207 supports customizable relay transmission paths and multi-level relaying. The module automatically forwards data, extending the wireless transmission distance, making it suitable for communication in ultra-long-distance or obstacle-rich environments.
Remote Parameter Configuration
Supports using serial commands and configuration software to read and set parameters of remote devices via LoRa wireless, significantly reducing operation and maintenance debugging costs
Signal Diagnosis & Fast Deployment
With the diagnosis Solves the most painful signal challenges in wireless deployment (interference, distance judgment, quality assessment), saving significant debugging time and ensuring stable operation.
Data Security
Data is encrypted during LoRa transmission to ensure enhanced security. Encryption keys are user-configurable; communication is only possible between devices with matching keys.

Building Control Application
Large office buildings require zoned management such as air conditioners and electric lights.In this scenario, multiple LG207 units can be deployed to connect with the air conditioners and lights in different zones, enabling independent control over the operation of equipment in each specific area.
IO Remote Control Application
By using paired LG207 devices, water level detection signals (DI) are wireless transmitted to the remote end to control water supply equipment (DO), realizing automated water replenishment for production.
