DSD TECH SH-U11F Geïsoleerde USB naar RS485 RS422 Converter Ingebouwde FTDI-chip voor industriële toepassing

Perfect apparat om KNX installatie te debuggen met modbus interface

If you need RS232, RS485 and similar - especially if you want long term reliability/stability, protection from over-voltage, and flexibility, DSD Tech is the way to go. Can’t recommend them enoughAt this point I’ve purchased probably 2 or 3 dozen UART/TTL USB adapters from other brands/sellers in my lifetime. I used to think “they’re all the same- cheap, but they work” - but I realized over time that eventually ended up in the trash for one of several reasons- voltage not supported, baud rate not supported, or (most common) unexpectedly stopped functioningWith most of the other brands, you have to guess what voltage is supported- if you need anything other than 3.3v, it’s a dice roll. Ditto with baud rate. Need to support more than 1Mbps? Very few sellers even know the max rate of the chip, let alone disclose it to buyersThe DSD products all have clear and complete documentation so you know exactly what you’re getting- they’ll tell you “this model only supports X and Y voltage”, or “this model has a max of Z baudrate”, so you know which variant to getMost (or all) of the DSD products have isolated circuitry so they don’t fry your USB port (or themselves) when you inevitably connect to the wrong pinsYou get exactly what the listing says. And they seem to make just about everything. My favorite is the UART TTL adapter that has support via jumpers for 1.8v, 3.3v and 5v and some less common voltages in betweenI will never buy a no-name brand again- these may use generic chips underneath, but DTD is not a generic brandThe prices are very good- maybe a little more than sone competitors- but it’s worth paying a few extra dollars when you know it will do everything you need into the foreseeable future and won’t die either

Aussitot branché aussitôt disponible, y compris sous Linux debian, reconnu par les drivers standard et confirme au standard 422/485, très bon rapport design / facilité / prix, reste à voir la duree de vie...J'apprécie particulièrement les résistances de terminaison sélectionnables par jumper, que l'on ne retrouve que sur des cartes a plusieurs centaines d'euros... Bien joué !

This product does not work and I can't return it. Nice.

The advantage of this unit is that it uses a USB2 B port so if your computer has USB C ports you're not limited to the USB A cable supplied. For a MacBook Pro with USB C ports just dug out the USB C to 2B printer lead and adapter sprang into life enabling configuration and monitoring of the ModBus slaves.

Lo utilizo para conexiones con HMI (es el tercero que compro, para diferentes proyectos) y el funcionamiento es perfecto.
