Moxa UPort 1130-1 Port USB-to-Serial RS-422/485 Converter - Reliable

Our review of the Moxa UPort 1130 evaluates a compact USB-to-serial adapter aimed at engineers and technicians who need a stable RS-422/485 connection from modern PCs. The bottom line: this adapter excels at high-speed serial data bridging with support for USB 2.0 and a maximum 921.6 kbps baudrate, making it a practical choice when legacy serial devices must interface with current systems. The UPort 1130 is straightforward to install, offers useful wiring flexibility with a mini DB9-to-terminal block adapter, and provides clear activity LEDs for quick diagnostics.

Key Features

• USB 2.0 compatibility: Ensures broad host support and up to 12 Mbps USB data rate for reliable connection to most modern computers.
• High baudrate: Supports a maximum 921.6 kbps baudrate so demanding serial data streams can be handled without bottlenecking.
• Cross-platform drivers: Drivers for Windows, WinCE, and Linux simplify deployment across a variety of embedded and desktop environments.
• Wiring flexibility: The mini DB9 female to terminal block adapter makes it easier to connect to industrial wiring and reduces cable clutter.
• Activity LEDs: Built-in USB and TxD/RxD LEDs provide instant visual confirmation of power and serial traffic during troubleshooting.

Who It's For

The UPort 1130 is best for system integrators, field technicians, and lab engineers who need a compact, robust USB-to-serial converter to link PCs or industrial controllers to RS-422 or RS-485 devices. Its high baudrate and cross-platform drivers are particularly useful in test benches, automation systems, and equipment maintenance where reliable serial throughput matters.

It is less suitable for users who require multiple serial ports in one box or plug-and-play solutions without any driver installation; those customers should consider multiport adapters or native serial interface cards instead.

Pros & Cons

Pros

• Compact adapter with USB 2.0 support that fits into tight workspaces and offers broad host compatibility.
• Very high maximum baudrate of 921.6 kbps, useful for fast data logging and industrial communication.
• Drivers available for Windows, WinCE, and Linux, easing integration across platforms.
• Mini DB9-to-terminal block and LEDs simplify wiring and troubleshooting on-site.

Cons

• Single-port design limits use when multiple serial connections are needed on the same host.
• Requires driver installation on some systems, so true plug-and-play convenience is not guaranteed in all environments.
