There are certain operational scenarios that may require you to convert back and forth between Ethernet IP/TCP packets and serial transmissions from devices using the RS232/RS422/RS485 protocols. To accomplish this feat you will often use a piece of hardware called a serial to Ethernet converter. This small device is also known as a serial device server and models are available in various sizes.
In this article, we will try to figure out how remote RS232 and other serial ports work and talk about the methods to convert RS232 to Ethernet, or in fact, convert any serial port over the network.

Serial to Ethernet converter - who is it for?
A Serial to Ethernet converter is usually used to enable a device with a serial interface to connect to a remote computer over a network. Many industrial and consumer devices are equipped with RS232/RS422/RS485 ports. By using an RS232 to Ethernet adapter you can access and control remote printers, barcode scanners, industrial monitoring sensors, and any other network-attached serial device from one central location. This saves time and increases your efficiency.
To conveniently work with such equipment we need to access remote devices, and the easiest way to do it would be to convert a serial port to Ethernet. Serial to Ethernet Converter is an electronic appliance or a specialized software which converts RS232, RS485 or RS422 serial data signals to Ethernet. Both software and hardware Serial to Ethernet Adapters works in the same way. The serial port signal goes to the network connection and it is being converted to the dedicated network protocol (TCP/IP/Ethernet). To receive this connection on the remote computer RS232 converter performs the opposite - converts network protocol to the serial signal again.
So, the importance of having RS232 to Ethernet Converter, when you work with serial devices, is obvious. And there are two ways to complete the remote access for your serial port device or app - software and hardware converters.
