How to receive data from RS232-to-Ethernet converter?

Question

Electronics

There is some machine that has a COM port (RS232). There was a task of receiving data from its COM port.
As far as I know, there are converters that convert serial port data (RS232/RS485) to Ethernet. For example, like this one:

After I connect the machine via RS232 to this converter, how can I get the IP data? The converter will have its own IP address.
What should I do with this address? How to receive data from the machine through this converter? Can I set up a Socket server in Node.js to listen on the IP address of the converter and send data to it?
Or will you have to write some specialized software?

Answer 1

These converters come with software that creates a virtual com port. After that, the device can be used in the same way as if it was connected directly.
Usually the device pretends to be a server, so you have to write a client.
Do you have documentation for the machine? What are you going to give him?
You can write an application in anything, even in brainfuck - as long as your language supports sockets.

Answer 2

Usually, such Chinese shits are put in pairs, that is, the output is also a comport that is already connected to the computer and the standard software of the machine is used.
But there is a use case when special software is installed on the computer.
Since the devices are very Chinese, you need to study the documentation and torture the seller how a virtual comport is organized on a computer.
I would advise you to buy something more decent, for example NPORT 5110.
If it's expensive then watch Avito, these things are very popular in some industries and you can find a brand new one for half the price.
