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

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 !

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

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.

This is my second unit with the same issue. I am using a MDO34 oscilloscope and can see my 485 buses drop from 4.4 V to 400 mV whenever I connect this 485 converter. I am using another brand and it works fine. Fortunately, my Rs485 chips can handle the issue and recover. Can't say the same for DSD TECH. I guess I will have to look elsewhere to find a USB converter.

This devices works well and is easy to set up. Just be aware you can set it up for 4 wire 422 but not 4 wire 485.

I have it connected to laptop running windows 10. Recognized and installed drivers. Was able to access and send and receive data. Seem to be well built. Leds show power and data (tx/rx).

This is a perfect solution for building new controllers for older hardware. the 485 is a rare beast (in my experience) but this allowed me to easily build a controller to run from the Latest o/s on to the oldest hardware.Easy to work with, well made. was able to build and deploy the test configuration in under 20 minutes. The full working model took a couple of weeks, as I wanted it to do so much! but none of it was difficult.The good documentation from the manufacturer was most pleasing!
