I replaced an unreliable RS485 hat on a Raspberry Pi with this interface. It was plug-and-play and all I had to do to make my existing C program which controls two VFD drives with Modbus over RS485 work with this box was to change the serial port name from ttyS0 to ttyUSB0 in the Modbus RTU init call.It looks/feels very high quality and it worked out of the box without having to tinker.

The Waveshare FT232RNL USB to RS232/485/422/TTL Interface Converter is a robust and versatile tool that has significantly simplified my work with legacy industrial equipment. As someone who frequently interfaces between modern computers and older industrial systems, this converter has become an indispensable part of my toolkit.The standout feature of this device is its industrial-grade isolation. This provides crucial protection for both the connected devices and the data integrity, especially in environments prone to electrical noise or ground loop issues. I've used it in several factory settings, and it has performed flawlessly, maintaining stable connections even in electrically noisy environments.The versatility of this converter is impressive. It supports multiple serial protocols (RS232, RS485, RS422, and TTL), making it a one-stop solution for various interfacing needs. The ability to switch between these protocols via jumper settings is convenient, though it does require careful reading of the manual to set up correctly.Build quality is excellent, with a sturdy metal casing that feels like it can withstand the rigors of industrial environments. The USB connection is solid, and I haven't experienced any disconnection issues, even when the cable is under stress.

Il convertitore USB a RS232/485/422/TTL è stato esattamente quello di cui avevo bisogno per collegare vecchi strumenti o programmatori al mio computer. L’ho installato senza problemi e funziona perfettamente. La connessione è stabile e mi ha permesso di continuare a utilizzare dispositivi che pensavo di dover abbandonare o che letteralmente non sapevo più come connettere.

IMPORTANTE: Este aparato NO SIRVE para conectar antiguos ratones por puerto serie ni nada que se le parezca.Internamente este adaptador de puerto serie RS232 a USB no tiene conectados los nueve pines que necesitaría cualquier ratón o dispositivo que conecta por puerto serie, sino que únicamente tiene conectados los tres que permiten realizar envío y transmisión de datos.Si usas un sistema operativo LINUX deberías poderlo usar directamente, siempre que tenga preinstalado el comando lsusb (que sería lo normal. En todo caso, instalar lsusb resulta sencillo).Para sistemas WINDOWS y MAC el fabricante proporciona los programas que podemos necesitar (básicamente, el equivalente al comando lsusb).Si lo que quieres es volver a usar algún antiguo dispositivo por puerto serie RS232 en una computadora moderna con puerto USB, este mismo fabricante ofrece un cable USB a puerto serie con los nueve pines conectados internamente.Este producto está muy bien construído, con materiales de excelente calidad. Es robusto, y las pruebas que hemos realizado, orientadas inicialmente a intentar conectar nuestros antiguos ratones por puerto serie, y posteriormente a verificar su correcto funcionamiento, han sido satisfactorias en el sentido de que realiza a la perfección la tarea para la que ha sido diseñado: transmisión de datos por puerto serie con las máximas garantías de que tanto los bits de stop, de datos, de control y la velocidad de transmisión se ajustan a nuestras necesidades particulares.Este aparato se utiliza con ciertas aplicaciones o programas que transmiten información a través del puerto serie, y en las que conectar el resto de pines del RS232 no aporta nada.

This is not a toy like the cheap USB-TTL chips you can get from various vendors, it mean serious business. The isolation is excellent, and lets you know you're not going to be putting the wrong voltage in the wrong place, which helps keep the smoke inside the chips.Setup is pretty easy, and the chip is one of the better USB-to-whatever chips you can get.If you're doing any dev work and need to speak 232/485/422/TTL, this is absolutely worth having in your toolkit! Everything I've thrown at it so far has worked great, but I will amend my review if I do find anything amiss.

Adaptateur USB série de très bonne qualité on peut facilement brancher les fils et avoir une connexion USB sur PC qui est immédiatement reconnu sur Windows et Linuxje l'utilise dans le travail pour des projets informatiques et ça évite d'avoir trois adaptateurs différents pour chacun des protocoles série il suffit de refaire le branchement en utilisant simplement un tournevis et le tour est joué pour pouvoir envoyer les commandes par l'interface USBJe recommende
