This adapter allows me to integrate older equipment with technically obsolete interfaces. I can opt between RS232 and RS485 with a glide switch. No drivers are required; I used it with Windows 11 with no drivers though drivers are available from Waveshare. It's very easy and straight forward to use with a basic build and I like that a terminating resistor is onboard. All said and done this is a good adaptor for a fair price. --- ## 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.co.za/products/683494663-usb-to-rs232-485-serial-converter-onboard-original-ft232rnl-chip](https://www.desertcart.co.za/products/683494663-usb-to-rs232-485-serial-converter-onboard-original-ft232rnl-chip) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-11*
