Overview

The Moxa NPort 5600-DT Series are 8-port RS-232/422/485 desktop serial device servers offering the connectivity capability of a rackmount unit in a compact form factor. Designed for installations where DIN-rail or 19-inch rack mounting is not available, they feature dual Ethernet ports for cascade wiring, an LCD panel for easy IP configuration, and flexible power inputs.

Key Features

  • 8 serial ports supporting RS-232/422/485 (model dependent)
  • Compact desktop form factor — no rack required
  • Two 10/100M Ethernet ports for convenient cascade wiring (eliminates need for a separate Ethernet switch)
  • LCD panel and push buttons for easy IP address configuration (standard temp. models)
  • Configure via Telnet, web browser (HTTP/HTTPS), Windows Utility, or Serial Console
  • Socket modes: TCP Server, TCP Client, UDP, Real COM
  • 2 kV serial isolation on NPort 5650I-8-DT models
  • Adjustable RS-485 termination (120 Ω) and pull high/low resistors (1 kΩ / 150 kΩ) via DIP switches
  • Dual power inputs: terminal block + power jack (12–48 VDC) with reverse polarity protection
  • SNMP MIB-II for network management; built-in buzzer and RTC for alerts
  • Metal housing — desktop, DIN-rail (optional), or wall mount (optional kit)
  • 5-year warranty

Serial Interface

The NPort 5610-8-DT provides RS-232 via DB9 connectors; the NPort 5610-8-DT-J uses 8-pin RJ45 connectors for RS-232. The NPort 5650-8-DT series provides RS-232/422/485 via DB9 (or 8-pin RJ45 for the -J variant). The NPort 5650I-8-DT adds 2 kV serial isolation. All models support baud rates to 921.6 kbps with full ADDC for RS-485 operation.

Cascade Ethernet Wiring

The dual RJ45 Ethernet switch ports allow units to be daisy-chained, reducing wiring complexity and eliminating the need for a separate Ethernet switch at each device location.

Driver & Platform Support

Windows Real COM drivers support Windows 11 through 95 and Windows Server 2022 through 2008. Linux Real TTY drivers cover kernel 2.4.x through 6.x. macOS Fixed TTY support for versions 10.12 through 11.x. ARM-based Linux (kernel 4.x/5.x) and Android 3.1.x+ are also supported.

Power & Environmental

Accepts 12 to 48 VDC via dual inputs (terminal block and power jack) with reverse polarity protection. Standard models operate 0 to 55°C; wide-temperature (-T) models extend to -40 to 75°C. Metal housing rated IP30 equivalent. Dimensions: 229 x 46 x 125 mm (with ears).

Certifications

CE (EN 55032/35), FCC Part 15B Class A, UL 60950-1, IEC 62368-1. RoHS, CRoHS, WEEE compliant. MTBF: 836,374 hours (Telcordia).
