Communication gateway UC100

telemetryIoTRS-485

Overview
Milesight UC100 is a compact Modbus RS485 to LoRaWAN® converter designed to read Modbus RTU devices and transmit site data over LoRaWAN®. It supports local USB Type‑C configuration, remote configuration via LoRa downlink, autonomous execution of IF‑THEN rules when the network is unavailable, Milesight D2D roles (Controller & Agent) for direct device‑to‑device interactions, and FUOTA for remote firmware updates.

Key features

• Data collection: supports reading up to 64 registers
• Local & remote configuration: USB Type‑C local config and LoRa downlink remote config
• Autonomous operation: executes IF‑THEN commands locally during network outages
• Intelligent Trigger System: up to 16 commands with custom trigger conditions and actions
• Milesight D2D support: functions as D2D Controller and Agent for direct device communication
• FUOTA support: Firmware Update Over‑The‑Air via LoRa® network
• Data integrity: onboard storage (historical records), data retrieval and retransmission to avoid data loss
