The SDS‑485 converter is designed for:

• 🔄 Bidirectional signal conversion between RS‑485 and Ethernet interfaces;
• 🌐 Connecting RS‑485 devices to a local or global Ethernet network;
• 🛡 Reliable data exchange in industrial networks using built‑in galvanic isolation;
• ✅ Integration of industrial devices into SCADA systems, measurement, and monitoring complexes without requiring a physical COM port on the PC.

The device supports virtual COM port creation and includes a built‑in WEB interface for configuration.

Main Functions

• 🔄 Mutual signal conversion RS‑485 ↔ Ethernet;
• ⚡ Automatic data direction detection in RS‑485 half‑duplex mode;
• 🛡 Galvanic isolation of interfaces, protecting equipment from potential differences and transient surges;
• 💻 Virtual COM port creation for operation with standard software using a hardware COM port;
• 🌐 Built‑in WEB interface for configuring network parameters and operating modes;
• 🔋 Powered from 24 V DC or an external power adapter, ensuring stable operation in industrial conditions.

Supported Operating Modes

• ✅ TCP Server – accepts incoming client connections;
• ✅ TCP Client – initiates connection to a remote server;
• ✅ UDP – low‑latency data transmission via the UDP protocol;
• ✅ RFC2217 – serial data over TCP with port signal control support;
• ✅ MCSC (Multi‑Channel Serial Communication) – multi‑channel operation for complex network integration;
• ✅ RealCOM – transparent virtual COM port mode for SCADA and monitoring systems.
