StarTech.com 4 Port Native PCI Express RS232 Serial Adapter Card with 16550 UART

Product Overview

AI-generated summary

StarTech’s 4-port native PCIe RS232 adapter is a sensible “get it working” card if you’ve got older serial gear (routers, industrial controllers, UPS units, patch panels) and you’re trying to avoid USB-to-serial nonsense. The big win here is that it presents real serial ports to the OS with proper UART support, which typically means fewer weird timing issues and less driver hassle than cheaper converters. At £77.45 ex-VAT, it’s priced like something you’d buy once, install cleanly, and then forget—especially in a UK office/warehouse environment where RS232 is still very much alive.

That said, it’s only a good fit if your host still has a compatible PCIe slot and your devices are truly RS232 (not RS-422/RS-485, not Ethernet). If you’re expecting it to modernise a fully “networked” workflow or you’re mostly doing occasional testing, you might be better off with a lower-cost USB serial adapter per workstation. Also, if you’re mapping ports through software that assumes specific COM ordering, plan on a bit of housekeeping after install. Overall: buy it if you need reliable multiport RS232 in a server/desktop PCIe and you value stability over experimenting. Skip it if you’re chasing compatibility outside RS232 or you don’t control the PCIe environment.
