Serial port over IP Network - access RS232 over TCP/IP

Olga Weis

When we talk about IP networking, some might think we only talk about the Internet. True, IP stands for Internet Protocol, but any network can utilize this protocol to transfer data between computers. Thus local area networks (LAN) and enterprise networks fall into this category too. In an IP network all nodes need to be configured with the TCP/IP suite.

This protocol allows sending and receiving data in a number of ways, and this includes accessing remote ports in the network – see below.

How to access remote serial port over IP

We often come across situations when we need to use serial devices, which we cannot access physically, they could be located at a long distance from us or it’s just not feasible to connect to it. What do we do in such cases? We use a special software application – Serial to Ethernet Connector. It allows to work with serial ports remotely, e.g. to access serial port over Internet or share serial port over IP, etc., so you can use devices connected to them as if they were inserted locally. The actual distance does not really matter – the device can be attached to a computer across your cubicle or across the globe, the way they become accessible to us is just the same.

Share serial over IP

The way Serial to Ethernet Connector (SEC) works is pretty simple – once installed on the local and remote machines it creates a virtual bridge between them so they can talk to each other. This serial over IP software enables network users to access the contents or functionality of a remote serial device as if it were inserted directly into your machine.

Here ‘Server’ is a machine that shares serial over TCP IP, while ‘Client’ is a machine that needs to access serial port over TCP IP.

Your step-by-step guide on how to use Serial to Ethernet Connector:

  1. Download and install the application on the computers that need to share and access serial port over IP (this can include virtual machines too).
  2. Launch the app on the server and choose ‘Create Server Connection’ in the menu, setup the connection parameters. Share a required serial over IP.
  3. Launch the app on the client and choose ‘Create Client Connection’ in the menu, configure the connection.
  4. Once you connect to the port, you can start using a device inserted into it right away.

Serial to Ethernet Connector supports Windows and Linux, the latter version is currently a command-line app.
