## Questions & Answers

**Q: Do you need virtual port software on the pc?  or when you plug in the usb to the pc do the ports just appear in device manager**
A: It depends. The device uses an FTDI chip, which are fairly common. Some Windows computers will have the drivers for it, so when you plug in the USB cable, it will automatically install the driver and show up as a serial port COMx in the device manager (with x a number, depending on your hardware).
In a few cases I had to install the correct drivers. The unit comes with a small CD (mini CD) that can be used for it, except these days it is non rare to have a PC without reader. In that case, just go to the FTDI website and download the driver package. It should be fairly easy to find.

On Linux and Mac I suspect you will have to install the drivers as well.

**Q: is this converter compatible with linux?**
A: yes

### ⭐⭐⭐⭐⭐ 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.
