Common Pain Points
Traditional serial-to-Ethernet solutions often suffer from port interference when handling multiple devices, data loss or high latency during transmission, frequent crashes or hardware damage from industrial surges/static/power fluctuations, narrow voltage range unsuitable for complex field power supplies, tedious configuration slowing deployment, incomplete Modbus protocol support, and poor scalability for parallel multi-device communication — severely affecting stability, efficiency, and reliability in industrial automation, remote monitoring, and IoT projects.
Solution & Core Features
1.Dual Independent Ports — RS232 and RS485 ports operate fully independently and concurrently without interference, enabling one device to connect multiple serial devices simultaneously.
2.Industrial-Grade Protection & Stability — ARM Cortex-M4 240MHz dual-core processor, dual watchdog anti-crash mechanism, ESD Level 4 + Surge Level 3 + EFT Level 3 multi-level protection, DC 5-36V wide voltage input (overvoltage/overcurrent/reverse polarity/common-mode surge protection), -40°C~+85°C full-temperature operation.
3.Modbus Gateway Bidirectional Conversion — Built-in Modbus RTU ↔ TCP transparent conversion, supports heartbeat/registration packets for seamless integration with PLCs, sensors, and cloud platforms.
4.Multi-Protocol High-Speed Transmission — Supports TCP Client/Server, UDP, HTTP; up to 460800bps baud rate, 8 concurrent TCP clients, zero packet loss real-time transmission.
5.Easy Configuration & Management — Built-in web server + configuration software for fast setup, DIP switch/AT command/one-key factory reset, remote firmware upgrade, true plug-and-play.
