The USB and RS485/422 sides are thoroughly isolated from each other, to the extent that there's even an air gap built into the board. The RS485/422 circuitry incorporates extensive protection components, along with configurable termination resistors (selected via two onboard jumpers).The converter is housed in a sturdy plastic case that supports DIN-rail and surface mounting. The kit comes with a USB 2.0 A-to-B cable, plus a mini screwdriver for the terminal block. There weren't any instructions in the box, but the device is straightforward enough.In use, the converter performs well, with the genuine FTDI FT232RNL chip providing reliable and predictable operation. The RX/TX lights help with troubleshooting and are easy to see. Overall, excellent quality and functionality. Highly recommended. ### ⭐⭐⭐⭐ Works as one would expect, since it appears to be a Waveshare product *by V***D on August 2, 2023* Converter works as expected, not sure what's up with the branding since it's got Waveshare logo on the unit and the box.Got a little isolating 5V DC/DC in there so it can provide power to the RS422/485 side without requiring a separate power supply. Also jumpers for selectable termination resistors. Nice separation between the hot and cold sides. And TVS protection. Pretty well engineered. ## Frequently Bought Together - coolwell Industrial Grade Isolated USB to RS485/422 Converter, with Original FT232RL and SP485EEN, Supports Mac, Linux, Android, Wince, Windows 10 8.1 8 7 XP - USB to RS485 Converter Industrial Adapter Original FT232RL and SP485EEN Fast Communication Embedded Protection Circuits Resettable Fuse ESD Protection - DSD TECH SH-U11F Isolated USB to RS485 RS422 Converter Built-in FTDI chip for Industrial Application --- ## 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.tn/products/533758085-coolwellindustrial-grade-isolated-usb-to-rs485-422-converter-with-original](https://www.desertcart.tn/products/533758085-coolwellindustrial-grade-isolated-usb-to-rs485-422-converter-with-original) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-18*
