Industrial 4-Port Serial Device Server with Managed Ethernet Switch

Enhance your industrial networking infrastructure with this robust 4-Port RS-232/422/485 Serial Device Server, designed to bridge legacy serial equipment with high-performance Ethernet networks. Built for scalability, reliability, and real-time data communication, this device is ideal for demanding applications across factory automation, intelligent transportation, and energy management.

Key Features

  • Multi-Protocol Support: Four RS-232/422/485 serial ports provide flexible communication with a wide range of legacy devices.
  • Built-In Managed Ethernet Switch: Integrates 5-port Ethernet switching to simplify network architecture and reduce complexity.
  • Fiber and Copper Connectivity: Choose fiber models with 2 fiber SC ports and 3 copper ports, or all-copper models with 5 Ethernet ports for robust connectivity.
  • Industrial-Grade Reliability: Operates in extreme temperatures from -40 to 75°C, with 15 KV ESD protection and comprehensive surge protection.
  • Advanced Networking Protocols: Supports QoS, VLAN, IGMP snooping/GMRP, SNMPv1/v2c/v3, LACP, and RMON for intelligent network traffic control.
  • Redundancy and Recovery: Ensure network uptime with Ethernet redundancy via Turbo Ring and Turbo Chain (recovery time under 20 ms) or RSTP/STP (IEEE 802.1w/D).
  • Serial Data Optimization: Built-in Serial QoS prioritizes critical data transmission over serial links.
  • Electrical Isolation: 2 kV isolation for serial signals (in isolation models) to prevent data corruption and enhance device longevity.
  • Configuration Flexibility: Adjustable pull high/low resistors on RS-485 ports to match your specific communication setup.

Technical Specifications

  • 4 RS-232/422/485 serial ports
  • 3 10/100BaseT(X) Ethernet ports
  • 2 100M single-mode fiber ports with SC connectors (fiber models only)
  • Surge protection for serial, Ethernet, and power interfaces
  • 15 KV ESD surge protection
  • Wide power input: 12 to 48 VDC
  • Operating temperature range: -40 to 75°C

Designed for mission-critical applications, this serial device server provides reliable industrial serial-to-Ethernet connectivity. Whether you're upgrading legacy systems or expanding your network, it's a future-proof solution for seamless and secure data transmission in harsh environments.
