StarTech.com 4-Port Serial PCIe Card, Quad-Port PCI Express to RS232/RS422/RS485 (DB9) Serial Card, Low-Profile Bracket Incl., 16C1050 UART, Windows/Linux, TAA Compliant - Level-4 ESD Protection

Product Overview

AI-generated summary

If you’ve got legacy kit that still talks RS232/RS422/RS485 and you need reliable serial connectivity in a modern Windows or Linux box, this StarTech quad-port PCIe card is a sensible, no-fuss choice. The big day-to-day win is you’re not juggling cheap USB-to-serial dongles or flaky ports—this is a proper PCIe interface with a real UART onboard, and the included low-profile bracket makes it easy to drop into tighter servers/small form factor PCs. At £145 ex-VAT, it’s good value when you consider the cost of downtime and rework from unreliable serial hardware.

That said, I wouldn’t buy it if you only need one or two serial ports, or if your environment already has known-good serial adapters you can reuse. Also, don’t assume “it’s an industrial card” means it’ll magically suit every weird RS485 wiring situation—RS485 tends to be more about cabling/termination/grounding than the card itself. If you’re dealing with high-noise locations, the mention of stronger ESD protection is reassuring, but your installation still matters. Overall: buy it if you need multiple dependable DB9 serial ports in a proper PC/server, and skip it if you’re light on ports or just need a quick, occasional connection.
