Modbus Gateway – SETU Series
Seamless Integration Between Modbus RTU/ASCII and Modbus TCP Networks
Avyanna’s SETU Transparent Serial Device Server series is designed for industries that need simple, dependable, and fully transparent communication between RS-232/422/485 serial devices and modern Ethernet networks. With no protocol conversion and zero data manipulation, the Transparent series ensures that your legacy serial equipment communicates over IP exactly as intended, fast, accurate, and uninterrupted.
Whether you’re upgrading old systems or integrating serial devices into new network architectures, our serial device server solutions deliver seamless connectivity with industrial-grade reliability.
Why Choose the SETU Modbus Gateway?
1. True Transparent Serial-to-Ethernet Communication
Each serial port can be configured independently as a Modbus RTU/ASCII Client or Server, making it extremely flexible for complex industrial architectures.
2. Supports Modbus TCP, RTU & ASCII – All in One Device
The SETU Modbus gateway acts as a translator between serial Modbus devices and Ethernet-based Modbus TCP systems, ideal for SCADA, PLC, EMS, and manufacturing control networks.
3. Industrial Grade Performance & Reliability
Equipped with:
‣ Metal enclosure with IP54 protection
‣ DIN-rail mounting
‣ High ESD protection on all serial ports
‣ 1.5kV magnetic isolation on Ethernet
‣ Wide 9–36V DC input
Engineered to operate reliably in electrically noisy, vibration-prone, or harsh industrial conditions.
4. Multi-Master & High-Density Connectivity
Each serial port supports up to 10 simultaneous connections under Modbus client mode, perfect for SCADA redundancy, parallel monitoring, and multi-system integration.
5. Easy Configuration – Web UI & Windows Utility
Setup is effortless through:
‣Web configuration
‣Windows configuration tool
‣Standard Modbus TCP/IP support
This makes the SETU industrial gateway server simple to deploy, scale, and manage.
