How to access remote RS232 over IP/TCP

Olga Weis Olga Weis

The problem of enabling remote access to an RS232 device over IP network arises when you need to connect a serial device that is not close to your local computer. It is not as difficult as it seems – as long as your local and remote computers are connected over the network, for example, a local network or Internet. Resolving it does not require buying a very long cable or trying sophisticated tricks, but special software. Things are much simpler with Serial to Ethernet Connector; This application allows you to provide access to an RS232 port over IP/TCP/Internet, regardless of the distance between the server and client computers.

Share RS232 over IP Network

Let's look at the following situation: there is a serial device connected to your local machine, and you want it to communicate with an application on a remote computer of the network. Serial to Ethernet Connector (SEC) makes it possible by creating a virtual connection to RS232 over IP, Ethernet or any other network. Install the software on the server machine (in this case your local PC) and on the client (the remote computer that needs to access a device). SEC will create a virtual bridge between the application on the remote machine and RS232 over IP, allowing them to communicate.

If you need to share a remote RS232 over Ethernet, access a remote RS232 over IP network, SEC is the solution you need. Install it on all your machines on the network, this will connect the RS232 port to the network and the functionality of a device connected to the port or the data stored on it will be available for all users on the network.

Work with serial devices with the aid of the SEC is no different from working with them when they are physically connected to your machine.

How to use Serial to Ethernet Connector:

  1. Download the app.
  2. Install on all computers on your network (or virtual machines with applications that need to access serial ports).
  3. Select the "Create Server Connection" option in the main application window.
  4. Set up connection parameters.
  5. Create a client connection on a remote computer.

That's it – now you can start working with a remote RS232 port over the network.

The application supports Windows and Linux. Note that the Linux version is command-line.
