I bought this specifically to update the firmware on my Denon DN-500AV, which requires a traditional serial connection. Modern laptops obviously don't include RS-232 ports anymore, so this adapter was exactly what I needed. The installation was straightforward, my Mac recognised the adapter without any issues, and the firmware update completed successfully on the first attempt. When you're updating firmware, the last thing you want is an unreliable connection, so I was pleased that it worked flawlessly. The adapter itself feels well made, with a decent-quality cable and solid connectors that don't feel loose or flimsy. I've gradually become a fan of UGREEN accessories over the years. In fact, while travelling in Guangzhou, China, I even made a point of visiting one of their retail stores. Everything I've bought from them—whether it's charging cables, display cables, hubs or adapters—has been consistently reliable, and this serial adapter is no exception. RS-232 may be old technology, but plenty of professional AV equipment, industrial devices and networking hardware still rely on it. If you need a dependable USB-to-serial adapter for maintaining legacy equipment, I'd happily recommend this one. Review: Good Quality, Durable and Correctly wired - Works just as described.

I have just tried by installing the Windows 8 drivers from the included mini-disc of drivers, and connecting it to my elderly Garmin E-Trex H. I was using the GPS to enter my site coordinates into a planetarium software programme and it worked just fine. This was using a laptop previously running 8.1 and recently upgraded to Windows 10. To my inexperienced eye it appears to be a well made cable which I bought specifically for W 8.1 but am delighted to discover that it also works with W10. Hope this helps. **Q: Hi, does this work with cisco products?** A: it dosent work with all cisco. routers ok switches not so much. better off getting startec one with ftdi chipset, that one definatly works. had to junk this one **Q: Does it work on linux?** A: Yes, It work well with Linux.Carol ## Customer Reviews ### ⭐⭐⭐⭐⭐ Exactly what I needed for legacy serial equipment *by B***Y on 24 July 2026* Like many people, I rarely need an RS-232 serial connection these days—but when you do need one, nothing else will do.
