USB to RS232 Serial DB9 Adapter Cable 1 ft - COM Port Retention

In this review the ICUSB232PRO 1 ft USB to RS232 Serial DB9 adapter is evaluated for users who need a reliable bridge between modern computers and legacy or industrial serial devices. The bottom line: it is a practical, no-nonsense adapter that keeps assigned serial COM port values and works well across platforms, making it ideal for technicians, lab engineers and anyone who routinely monitors or controls RS232 equipment from a laptop or desktop.

Key Features

• Broad compatibility: Connects legacy RS232 serial devices to USB on Windows, Linux and Mac OS so older peripherals stay usable without hardware upgrades.
• COM port retention: Retains assigned serial COM port values in nonvolatile memory so the same COM number is restored after reconnection, reducing setup time.
• Industrial use: Designed to interface with sensors, equipment and control boards, making it suitable for monitoring and automation tasks.
• Compact length: The 1 ft cable is convenient for bench setups and prevents excess cable clutter when connecting a nearby computer.
• Easy integration: Users report straightforward installation with limited driver fuss, which helps get systems running quickly.

Who It's For

The adapter is best for technicians, engineers and hobbyists who need a dependable way to connect and control serial devices such as industrial sensors, LED or digital signage controllers, and other RS232 peripherals from a modern computer. It is especially useful where maintaining a consistent COM assignment matters for automation scripts, legacy software, or serial terminal configurations.

Those who should look elsewhere are users needing long cable runs, high-channel multiport serial hubs, or specialized voltage/isolated serial interfaces; this single 1 ft adapter is a point solution rather than a multiport or isolated industrial gateway.

Pros & Cons

Pros

• Reliable COM retention simplifies reconnects and moves between USB ports.
• Works across Windows, Linux and Mac OS for broad interoperability.
• Users report good build quality and straightforward installation with some systems.

Cons

• At 1 ft length it may be too short for some installations that require longer reach.
