Overview

The Moxa UPort 1130I is a 1-port USB Type A to RS-422/485 converter with 2 kV isolation, built for engineers who need to connect legacy or field serial devices to laptops, workstations, and servers that no longer ship with a native COM port. It supports baudrates from 50 bps up to 921.6 kbps and data bits, stop bits, and parity spanning every common serial configuration. The compact ABS + polycarbonate housing fits in a laptop bag and travels with the engineer.

Key Features

  • 921.6 kbps maximum baudrate for fast data transmission
  • Drivers provided for Windows (11/10/8.x/7/Server 2000-2022), macOS 10.12-10.15, Linux kernel 2.4.x through 6.x, and WinCE
  • Virtual-machine support for VMware Fusion/ESXi and Parallels Desktop
  • Android 3.1.x and later supported via API
  • Arm-based platform support for Linux kernel 4.x/5.x/6.x and Windows 11 on Arm
  • Flow control: None, RTS/CTS, XON/XOFF
  • Parity: None, Even, Odd, Space, Mark (5/6/7/8 data bits, 1/1.5/2 stop bits)
  • 2 kV isolation between the USB and serial sides blocks ground-loop currents and blunts surge events, protecting the host PC and the field device.
  • LED indicators for USB link and TxD/RxD activity

Applications

  • Laptop field engineering – replace a missing native serial port with a USB dongle
  • Point-of-sale and retail peripherals (receipt printers, barcode readers, cash drawers)
  • Industrial instrumentation and data acquisition
  • Service and commissioning of PLCs, VFDs, and RS-485 fieldbus networks
  • Legacy COM-port application revival on modern hosts via virtual COM driver
  • Server rooms and workstations bridging to serial-only management interfaces

What’s Included

  • 1 x UPort 1130I USB-to-serial converter
  • 1 x quick installation guide
  • 1 x warranty card

Supported Platforms

Moxa supplies drivers covering every major desktop and server operating system produced in the last two decades. Windows users get virtual-COM drivers that present the converter as a standard COM port to existing applications. Linux support spans kernel 2.4.x through 6.x, covering long-life embedded targets and current distributions. macOS is supported through 10.15 (Catalina). Arm-based hosts (Apple Silicon via virtualisation, Windows 11 on Arm, and Arm Linux) are covered via current drivers, so the device works across mixed-architecture fleets.
