Product Overview

AI-generated summary

This StarTech PCIe 1‑port RS232 card is a solid, no-drama way to add a single serial (DB9) port to a Windows or Linux box, especially if you’re stuck with legacy kit—things like industrial equipment, label printers, older UPS/monitoring gear, or any “it only speaks RS232” scenario. At **£36.55 ex‑VAT**, it’s good value because you’re not paying for multiple ports you won’t use, and StarTech typically does well on driver reliability. The included usefulness here is the “just work” factor: you get a straightforward host controller and the basics you need without turning it into a project.

That said, I’d only buy this if you’re confident you truly need **one** RS232 port and you’re not actually dealing with RS485 or USB-only devices. Also, if you’re on a server or workstation with limited airflow/low-profile constraints, double-check your physical slot needs (low-profile options can matter depending on the chassis). And if your application is especially picky about serial timing/throughput, you should sanity-check that a standard UART/RS232 approach fits your device—some “serial” gear is picky about settings. But for most everyday UK B2B legacy connectivity jobs, this is the kind of dependable, inexpensive adapter that earns its keep.
