StarTech ICUSB2328I 8-Port Industrial USB to RS232 Serial Hub with Wall Mount Brackets

Overview :

The StarTech ICUSB2328I is a rugged, industrial-grade hub designed to convert a single USB port into eight RS232 serial ports. It is utilized by manufacturing engineers, laboratory technicians, and IT professionals who need to manage multiple legacy serial devices—such as PLCs, CNC machinery, sensors, and telecommunications equipment—from a modern PC or server.

Technically, the hub features high-performance 16C550 UARTs and supports data transfer rates up to 921.6 Kbps per port. It is specifically engineered for harsh environments, featuring a heavy-duty metal chassis and 15kV ESD (Electrostatic Discharge) protection to prevent electrical damage to sensitive connected hardware. Unlike consumer-grade adapters, this hub maintains assigned COM port values across reboots, ensuring that software configurations remain consistent even when the hub is disconnected and reconnected.

Deployment is highly versatile, with integrated mounting brackets for secure installation on walls, under desks, or within server racks. The hub is bus-powered for standard applications but includes an optional DC power jack (5V) for situations where the connected serial peripherals require additional power stability. It is “plug-and-play” across most modern operating systems, providing a scalable solution for expanding serial connectivity without opening the computer chassis.
