Waveshare USB to RS232/485 Serial Converter, Onboard Original FT232RNL Chip, Features More Stable Transmission, Suitable for Multiple Devices, Compatible with Mac/Linux/Android/Win11/10/8.1/8/7, etc

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.

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.

Worked great on PC. Able to connect to golf cart.

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.

Works perfect, exactly what I expected

Worked perfect for communication to my electric golf cart. Turned up my max speed. Performed the same on another cart and worked great for that cart as well.

High quality usb to serial device. The 3pin green wire block is removable which makes connecting it to your device nice and easy. When you plug it into a PC it’s FTDI drivers were detected and I had COM port right away with no messing around. It comes with a USB extension cord and nice small flat screwdriver, so you are good to go.

I used this adapter in conjunction with a IoT project in working on that needed a RS232 interface to a Wi-Fi enabled serial device to transmit MQTT data. Worked great out of the box and was recognized by my Raspberry Pi 2W running Ubuntu. Price point seems reasonable for a trusted brand.

Fonctionne très bien

I have ordered from Waveshare in the past and have been impressed enough with their consistent quality that I now refer to them in my regular list of Amazon sellers. 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.

Werkt out of the box

Bien

Worked perfect with Win11, no drivers to look for. The device was recognized by Win 11 and RS232 communication worked as expected. Its compact also, good, good.
