Sorry to bring this up, but RS-485 is for connecting a PC to system devices when programming. If I were you, I would check the converter function on a commercial Raspberry Pi. Next, install Docker on your Raspberry Pi using the command line that the author pointed out above. After that, you can install the hilschernetpi / Node-RED container. This way, you should have everything working. If it doesn't work, try the loader.to.
