RS485 to USB converter

Hello everyone,

I’m starting a new project and for this I’m trying to read data from a device that is running the RS485 protocol.

This is my first time working with this protocol and am a complete newb when it comes to this.
My current setup is :

Device (RS485) → Converter to USB → Arduino → Raspberry Pi

I was wondering if its just that easy to convert the RS485 to usb or if I’m missing something.


I have a USB to RS485 converter dongle for my PC to listen in on my Arduinos talking over RS485. It appears as just another COM port under windows and you can use it with any terminal program. Cost me a few GBP on eBay.

I'm guessing here but I would assume that it would appear as a TTY port under Raspbian when you plug it in to one of the USB ports on your Pi.

Cool, I guess it's just that easy then. Thanks for your reply
