### ⭐⭐⭐⭐⭐ Quick and simple RS422
*by S***Y on 20 July 2025*

Needed and RS-422 to test serial data to a radar system. This plugged into the laptop, drivers loaded automatically and worked straight away. Very happy with how it works and its price.

### ⭐⭐⭐⭐⭐ It just works!
*by B***R on 3 July 2025*

I required a full duplex USB to RS-422 converter on an urgent basis to communicate with a gas metering system; this was delivered next day, included all necessary drivers and worked perfectly, allowing us to keep our project running to schedule.

### ⭐⭐⭐⭐⭐ Worked well on Linux
*by J***Y on 24 April 2025*

I bought this to connect up to my Aurora solar inverter. Having the little module separate was helpful because my inverter had similar, so I wired the two together with a bit of old Cat5e network cable. The serial adapter itself “just worked” on Linux and the third-party utility I downloaded was able to grab the data flawlessly.
