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

Optimize your industrial networking with this robust 4-port RS-232/422/485 serial device server designed for seamless data communication and advanced Ethernet connectivity. Ideal for automation systems, energy management, and transportation applications, this industrial-grade solution combines serial-to-Ethernet conversion with a fully managed Ethernet switch and fiber options, ensuring high-speed, reliable data transfer in demanding environments.

Key Features and Benefits

  • 4 RS-232/422/485 Serial Ports – Supports multiple serial protocols, perfect for integrating legacy devices into modern networks.
  • Built-in Managed Switch – Provides up to 5 Ethernet ports, depending on model, enabling simplified network infrastructure.
  • Fiber and Copper Connectivity – S8455I fiber model includes 2 100M multi-mode fiber ports (SC connector) and 3 Ethernet ports; all-copper model features 5 Ethernet ports for flexible deployment.
  • High-Speed Redundancy – Supports Turbo Ring and Turbo Chain with recovery times under 20ms, or RSTP/STP (IEEE 802.1w/D) for maximum network uptime.
  • Advanced Networking Features – Includes QoS, VLAN, IGMP-snooping, GMRP, LACP, SNMP v1/v2c/v3, and RMON for optimal traffic control and monitoring.
  • Serial QoS Configuration – Prioritize critical serial communications across your Ethernet network with adjustable serial QoS settings.
  • Enhanced Protection and Reliability – 15 KV ESD protection, 2 kV isolation (on isolation models), and surge protection for serial, Ethernet, and power interfaces safeguard your equipment.
  • Industrial-Grade Durability – Operates in temperatures from 0 to 60°C and accepts wide 12 to 48 VDC power input, ideal for harsh environments.
  • Adjustable RS-485 Termination – Fine-tune pull high/low resistors for better signal integrity and reduced errors in RS-485 communication.

Whether you're upgrading a SCADA system, deploying in an oil and gas facility, or modernizing factory automation, this serial-to-Ethernet device server delivers the reliability, flexibility, and performance you need for mission-critical operations.
