Transparent – Serial Device Server (SETU Series)
Reliable, Transparent & Industrial-Grade Serial-to-Ethernet Connectivity
The SETU Series Modbus Gateway from Avyanna is engineered to bridge the communication gap between traditional Modbus/RTU and Modbus/ASCII serial devices and modern Ethernet-based Modbus TCP systems. Designed for industrial environments that rely on accurate real-time data, our Modbus gateway ensures simple, reliable, and bi-directional data flow between serial equipment and IP-based networks.
Whether you are upgrading legacy automation systems or scaling your Industry 4.0 infrastructure, the SETU Modbus Gateway operates as a powerful and stable industrial gateway server that keeps every device connected, efficiently and transparently.
What Makes the SETU Transparent Serial Device Server Ideal for Modern Industries?
1. True Bi-Directional Modbus Communication
No protocol rewriting. No data alteration. Just clean, direct, transparent transmission between serial and Ethernet systems, essential for OPC, SCADA, PLCs, meters, and automation controllers.
2. Supports RS-232, RS-422 & RS-485 on Every Port
Each serial device server model features software-selectable interfaces, allowing maximum flexibility for multi-vendor equipment.
3. Built for Industrial Environments
With a metal enclosure, IP54 protection, DIN-rail mounting, high ESD protection, and extended temperature tolerance, the SETU series is ready for harsh plant conditions.
4. Multiple Modes for Any Network Architecture
Easily configurable via Web UI or Windows Utility, supporting:
‣ TCP Server (up to 10 connections per port)
‣ UDP Server / Client
‣ VCOM (Virtual COM Port)
‣ Telnet
This makes each serial device server flexible enough for complex industrial topologies.
5. Secure & Stable Data Transmission: With features like:
‣ Built-in 120-ohm termination
‣ Pull-up/pull-down resistors for RS-485
‣ Galvanic & Optical isolation (model-dependent)
‣1.5kV magnetic Ethernet isolation
‣ Reverse voltage & ESD protection
You get consistent, noise-free data communication, even in electrically noisy environments.
