Serial Connectivity

NPort IA5000A Series

1, 2, and 4-port Serial Device Servers

The NPort IA5000A device servers deliver easy and reliable serial-to-Ethernet connectivity for the industrial automation market. The servers support several operation modes—TCP Server, TCP Client, UDP, Real COM, RFC2217, Reverse Telnet, Pair Connection, and Ethernet Modem—ensuring the compatibility of network software, and are an ideal choice for connecting RS-232/422/485 serial devices, such as PLCs, sensors, meters, motors, drives, barcode readers, and operator displays. The NPort IA5000A device servers come with a compact casing and a DIN-Rail mounting kit.

  • Enhanced surge protection for serial, LAN, and power
  • 2 KV isolation for serial signals
  • Rugged screw-type terminal blocks for power and serial connectors
  • C1D2 and ATEX certified for harsh industrial environments
  • Cascading Ethernet ports for easy wiring

Industrial Serial-to-fiber Media Converters

The IMC-101 industrial media converters provide industrial-grade media conversion between 10/100BaseT(X) and 100BaseFX (SC/ST connectors). The IMC-101 converters’ reliable industrial design is excellent for keeping your industrial automation applications running continuously, and each IMC-101 converter comes with a relay output warning alarm to help prevent damage and loss. The IMC-101 media converters are designed for harsh industrial environments, such as in hazardous locations (Class 1, Division 2/Zone 2, IECEx, DNV, and GL Certification), and comply with FCC, UL, and CE standards. The IMC-101 series is available in models that support an operating temperature from 0 to 60°C, and an extended operating temperature from -40 to 75°C. All IMC-101 series converters are subjected to a 100% burn-in test.

  • 10/100BaseT(X) auto-negotiation and auto-MDI/MDI-X
  • Link Fault Pass-Through (LFP)
  • Power failure, port break alarm by relay output
  • Redundant power inputs
  • -40 to 75°C operating temperature range (T models)
  • Designed for hazardous locations (Class 1 Div. 2/Zone 2, IECEx)

NPort S8455/NPort S8458 Series

Combo Switch / Serial Device Server

The NPort S8455/S8458 series combines an industrial device server with a full-function managed Ethernet switch by integrating a combination of fiber and Ethernet ports with 4 RS-232/422/485 serial ports. Combining a device server and switch in one product allows you to save space in your cabinet, reduce overall power consumption, and reduce costs, since you will not need to purchase a switch and serial device server separately.

The built-in switch function supports QoS, IGMP-snooping/GMRP, VLAN, Port Trunking, SNMPv1/v2c/v3, and IEEE 802.1X, allowing you to handle virtually any kind of application. The combo switch and serial device server achieves ring redundancy with standard STP/RSTP and Moxa’s proprietary Turbo Ring or Turbo Chain 2 redundancy protocols. The all-in-one design can be used to optimize and simplify your device network, and enhance reliability.

  • 4 RS-232/422/485 ports support serial QoS and 4 kV isolation protection (S8455 only)
  • Ethernet redundancy with Turbo Ring and Turbo Chain (recovery time < 20 ms) or RSTP/STP supported
  • QoS, IGMP-snooping/GMRP, VLAN, LACP, SNMPv1/v2c/v3, RMON supported
