Review: Solid, Reliable Works Exactly as Advertised - I purchased the Waveshare USB to RS232/485 serial adapter for integrating legacy industrial equipment with a modern system, and it has worked flawlessly. Build quality is excellent, with a solid enclosure and clearly labeled terminals that make wiring straightforward. The adapter was recognized immediately by my system with no driver headaches, and communication over both RS232 and RS485 has been stable and consistent. Data transmission is clean, with no dropouts or random disconnects, even during extended operation. It’s obvious this is designed with industrial and professional use in mind rather than being a cheap consumer adapter. I also appreciate the flexibility of having both RS232 and RS485 in a single unit, which saves space and eliminates the need for multiple converters. Overall, this is a dependable, well engineered product that does exactly what it claims. Highly recommended for anyone working with PLCs, CNC machines, industrial controls, or other serial communication applications.
Review: Fantastic USB to serial converter - I had several USB to serial adapters they no longer worked with Windows 10/11. Have this a try as I had a need to connect to an older RS-232 device. On my Win 10 laptop, it was plug and play. Worked with any applications I tried, even an old version of Procomm Plus. Windows 11 desktop needed a driver installed, quickly found on the website. It again works with every application I have tried. I like it so much, I am thinking of ordering a second one to keep in the laptop bag. I had several euro block 3 pin plugs in my parts box, so I made up a few different adapters (9 pin, 25 pin, and 1/8" plug) for quick connection. Well worth the price.

### ⭐⭐⭐⭐⭐ Great device, but check the switches on the side. Mine was shipped in rs232 mode.
*by D***. on July 30, 2025*

Works great. I was getting all data echoed back, but it turned out the device came with the switch in rs232 mode. Switching it to rs485 fixed the issue. It was a bit of a puzzle that a device sold as a usb to rs485 converter would be shipped with the switch in the rs232 mode.
