## Description

Features Onboard Original FT232RL and SP485EEN chip. Fast communication, stable and reliable, better compatibility Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance Onboard 15KV ESD isolation protection and 600W lightningproof & anti-surge protection Onboard 120R terminal resistor on the RS485/RS422 ports, enable by default, configurable by jumper 3 LEDs for indicating the power and transceiver status Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective Package include 1. USB TO RS485/422 x1 2. USB-A male to USB-B male cable ~1.2m x1 3. Screwdriver x1

Review: It's clear that a lot of thought went into designing this serial interface converter. 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.
Review: Points positifs 👍 : - 👍 Le design du convertisseur est bien pensé, avec une isolation claire entre les parties USB et RS485/422. - ⚡ La puce FTDI FT232RNL offre une compatibilité fiable et des performances stables. - 📱 Reconnaissance immédiate sous Windows, Android et macOS, sans installation complexe. - 🔧 Possibilité de montage sur rail DIN ou fixation sur une platine, ce qui est très pratique. - 🔌 Alimentation directe par le port USB, évitant l'ajout d'une alimentation externe. - ⚙️ Résistances de terminaison configurables via des jumpers, ajoutant de la flexibilité. - 💡 Les LEDs RX/TX sont utiles pour le dépannage. - 🛠️ Livré avec des accessoires pratiques comme un câble USB et un mini-tournevis. Points négatifs 👎 : - 📖 Absence de documentation, ce qui complique la prise en main pour un utilisateur novice.

*by M***E on 5 December 2024*

Ich habe es bisher nur unter Windows (11) probiert und da geht es einfach. Sicherlich ist jede Bastellösung aus Resten günstiger. Aber den Mehrpreis bin ich zwischenzeitlich gerne bereit zu zahlen wenn es einfach funktioniert ohne das man wieder eine kalte Lötstelle bei seiner Bastellösung sucht. Aber das geht bestimmt nur mir so
