StarTech.com 4 Port USB to RS232 Serial DB9 Adapter Hub

Product Overview

AI-generated summary

StarTech’s 4‑port USB‑to‑RS232 adapter hub is the kind of thing you buy when you’re stuck supporting older kit (routers, some industrial controllers, barcode/scales, legacy modems) and you need more than one serial line from a single USB port. For the UK B2B world, that’s a pretty common headache. The upside here is reliability and driver maturity—StarTech gear is usually straightforward to get working, and having DB9 physical ports means you can keep your existing serial cables and workflows without retooling everything. At £82.15 ex‑VAT, it’s not “cheap,” but it’s also not crazy given it’s four ports in one and designed for office/IT uptime rather than hobby tinkering.

Who should buy it: teams that need a small serial expansion for configuration/maintenance tasks, MSPs/resellers provisioning sites with mixed hardware, and anyone standardising on USB‑based serial access for multiple devices. Who should avoid it: if you’re expecting it to behave like a high‑throughput multi‑drop serial backplane, or if your environment is heavily locked down and you can’t control drivers/permissions—USB serial adapters can be picky depending on OS and policy. Also, if you only need one port, you’ll usually find better value with a single adapter; paying for four when you won’t use them is the main way this stops being good value.
