StarTech.com 4 Port USB to DB9 RS232 Serial Adapter Hub – Industrial DIN Rail and Wall Mountable

Product Overview

AI-generated summary

If you’ve got older RS-232 kit (think barcode scanners, label printers, CNC bits, industrial meters, some automation gear) and you need to bring it into a modern PC without faffing about with internal cards, this StarTech 4‑port USB-to-serial hub makes sense. At £92.71 ex‑VAT, the price feels fair for something that’s built to be mounted and used day-in/day-out, not just stuck on a desk. The DIN rail/wall-mount angle is genuinely useful in UK workshops and small factories where you want things tidy and accessible rather than living behind a monitor.

That said, it’s not a “buy once, forget forever” product. USB-to-serial adapters can be sensitive to driver behaviour and USB power management, and if you’re running it in a noisy industrial environment (or via dodgy hubs/long unpowered runs), you can still get flaky connections—especially under load. If you only need one or two ports, you’ll often get better value with simpler single/dual adapters and fewer moving parts. But for organisations that need four reliable RS-232 connections in one managed, mountable box—particularly where you don’t want the hassle of installing serial cards—this is a sensible, practical choice.
