Easy to use *by T***M on October 14, 2020* We use hundreds of these in our products. Best we have found. ### ⭐⭐⭐⭐ Received 2 1US & 1 CA *by R***X on February 21, 2022* Received 2 1US & 1 CA 1 sets on shelf as backup. ### ⭐⭐⭐⭐ Works just fine *by R***. on April 26, 2013* Using it for 422, no problems, only gave it 4 stars since the driver install did not go perfectly the first time. It seems to be a bit over priced for a USB serial converter.Bought another one after 5 years, someone has walked off with the one I had originally.When other RS422 adapters fail to work, this one works. No driver needed on Windows 7. ## Frequently Bought Together - StarTech.com 6ft (1.8m) 1-Port Professional RS422/485 USB Serial Cable Adapter with COM Retention, USB to RS422 Adapter - TAA - StarTech.com RS422 RS485 Serial DB9 to Terminal Block Adapter - Serial adapter - 5 pin terminal block to DB-9 (M) (black) , TAA (DB92422) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/7394927-startech-com-6ft-1-8m-1-port-professional-rs422-485](https://www.desertcart.pt/products/7394927-startech-com-6ft-1-8m-1-port-professional-rs422-485) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-04*
