Common Pain Points
Traditional serial communication devices often suffer from wired limitations requiring costly cabling in remote/harsh environments, unstable connectivity due to interference or distance, narrow voltage/temperature ranges causing failures in extreme conditions, complex setup/programming for IoT integration, frequent downtime without auto-recovery, and poor adaptability for legacy PLC/equipment upgrades, severely hindering reliable remote monitoring, data transmission, and cost-effective IoT deployment in industrial automation, smart grid, cold chain, and agriculture.
Solution & Core Features
1. Compact Industrial Design — Compact size (105.4 × 98 × 25 mm), rugged metal/ABS housing with IP20 protection, supports 35 mm DIN rail or panel mounting, easy deployment in space-limited cabinets or harsh environments.
2. Triple-Link 4G + Wi-Fi + Ethernet Backup — Powered by Qualcomm LTE Cat.4 module, supports domestic full-network coverage and mainstream overseas bands, automatic failover (WAN > Wi-Fi > 4G), 99.9% uptime even in remote areas.
3. Multi-Interface & Cloud-Ready Protocols — Supports RS232 + RS485 serial ports (1200–500000 bps baud rate), dual RJ45 Ethernet (WAN + LAN), Wi-Fi AP/STA, optional TTL; supports transparent TCP/UDP, HTTP/HTTPS, MQTT/MQTTS, WebSocket; Modbus TCP ↔ RTU gateway conversion for seamless PLC/SCADA integration.
4. Industrial-Grade Durability & High Reliability — 6–26 VDC input, full industrial temperature range -40°C to +85°C; hardware watchdog prevents crashes, ESD/surge/reverse-polarity protection, metal/ABS housing ensures 24/7 uninterrupted stable operation.
5. Remote OTA & Plug-and-Play — Pre-installed AT commands, remote configuration, OTA upgrade, logs, and alarm reporting; no site visits needed for maintenance; external SMA antenna connectors for 4G and Wi-Fi.
