B4J Question Working with RS-485 to Ethernet converter in B4J

Unless the manufacturer supplies an API, SDK or driver for direct interface to the converter, no.
You would also need the manual on how use the functions.

Perhaps I do not understand the structure of the converter itself, but the software provided by the manufacturer essentially creates a virtual com port. I only need to select 3 parameters that are known in advance: Net Protocol: TCP Client, Remote IP: the address set on the converter (eg 192.168.31.205), Remote Port: The port set on the converter (eg 20108). Can I do the same with B4J and send / receive data via Ethernet converter? Or is everything much more complicated and in fact it is not done directly but through a certain protocol?

On some projects, I'm using same thing (serial to ethernet). Serial can be RS232 or RS485 ... in my case it's also 485.
For me installing third party is also something what I would like to avoid. And only way to do that is wrote yourself virtual serial port software inside your application. To be able to do that, you need to know in detail protocol specification of manufacturer of 485/Ethernet which you are using. One which I use, protocol is not documented publicly so I (for now) decided to not do it.
Solution (or way) which I will probably go is to do RS485/ethernet by myself. You can think also of that way.
With B4X set of tools, you can do it with B4R on ESP32 ... then you would have RS485/WiFi with known protocol which you can simply use from your applications on desktop or mobile phones (and good is all programmed and code shared with B4X set of tools).
