High-Performance 4-Port Serial Device Server with Managed Ethernet Switch

Boost industrial connectivity and ensure mission-critical serial data transmission with this advanced 4-Port RS-232/422/485 Serial Device Server. Designed for industrial networking environments, this reliable solution features a built-in managed Ethernet switch and robust redundancy protocols. Ideal for factory automation, transportation, energy systems, and other IIoT applications that demand stable and secure data flow.

Key Features

  • Supports 4 RS-232/422/485 serial ports with adjustable pull high/low resistors for RS-485 protocols
  • Integrated managed Ethernet switch for efficient network backbone deployment
  • Model S8455I with fiber includes 2 100M single-mode SC fiber ports and 3 10/100BaseT(X) Ethernet ports
  • All-copper S8455I variant offers 5 10/100BaseT(X) Ethernet ports
  • Supports Ethernet redundancy with Turbo Ring and Turbo Chain (recovery time under 20 ms), RSTP/STP (IEEE 802.1w/802.1D)
  • Serial QoS to prioritize critical data transmission, ensuring time-sensitive performance
  • Advanced network features: QoS, IGMP-snooping, GMRP, VLAN, LACP, SNMPv1/v2c/v3, and RMON
  • 2 kV isolation protection for serial signals (on isolation models) enhances system reliability
  • Built-in surge protection for serial, Ethernet, and power interfaces for maximum uptime
  • 15 kV ESD protection for added resilience in harsh industrial environments
  • Wide operating temperature range: 0°C to 60°C with 12 to 48 VDC power input

Industrial-Grade Performance

This serial-to-Ethernet device server is purpose-built to convert legacy serial devices for modern IP-based communications. With versatile port configurations, robust isolation, and industrial-grade surge/ESD protection, it bridges the gap between traditional serial equipment and modern Ethernet infrastructure.

Ideal for IIoT Applications

Whether you're upgrading a factory floor, configuring a SCADA system, or deploying a long-distance fiber network, this reliable multi-port serial device server offers all the essential tools for high-speed, redundant, and secure communication between serial and Ethernet devices.
