Moxa UPort 1150 USB to RS-232/422/485 Converter

Overview

The Moxa UPort 1150 is a 1-port USB Type A to RS-232/422/485 multi-standard converter, 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)
• No galvanic isolation – suit the -I variant if the installation is exposed to ground-loop or surge risk.
• 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 1150 USB-to-serial converter
• 1 x Mini DB9F-to-terminal-block adapter
• 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.
