# WT460M - 4G+LAN

### **Wiman MAX Series IoT Gateways**

The **Wiman MAX Series Gateways** deliver robust and secure IoT connectivity for industrial and utility applications. Designed to support **RTU/TCP Modbus, Digital/Analog IO, and LoRa nodes**, these gateways enable seamless data transmission over **4G, LAN, and Wi-Fi** networks.

With **dual-server communication capability**, data can be transmitted simultaneously to two servers, ensuring redundancy and uninterrupted operation. Bidirectional communication supports simple read/write operations using **TCP, HTTP, and MQTT protocols**, with optional **SSL encryption** for enhanced security.

Advanced smart polling features—including **Edge-based, Time-based, IO-based, and Offline Log-based polling**—optimize data flow and reduce server load. Built-in data logging with expandable SD storage ensures zero data loss during network or server outages, making the MAX Series ideal for demanding industrial environments.

Remote configuration is supported via **PC utility, FTP, SMS, or server IP commands**, ensuring flexible deployment and maintenance.
