What is a serial to Ethernet Converter?
Serial to Ethernet converters technology is an electronic device capable of converting data packets received over a TCP / IP network to and from serial data signals. In simple words a serial to Ethernet converter is a device that takes a serial data signal and sends it over a network connection. In addition, it accepts any received network data and turns it into a serial signal. The hardware redirects the serial device over the network, thereby eliminating the need to physically connect it to the computer. Since there is no need to install an additional serial line, with an RS-485 over Ethernet device, you can rely on your existing LAN structure.
A serial to Ethernet converter is used when you want to connect a serial device that is not connected to the network to a computer that is either too far away sometimes on the other side of the world Or simply does not have a suitable serial port. The data transmission is depending on the used serial to Ethernet converter. To ensure the security of serial data transmitted over a network connection, the converter must support encryption using an SSL \ TLS connection.

Can I use serial to Ethernet converters so that two serial devices can connect over the network?
Yes, depending on the capabilities of the serial to Ethernet converter. This is called “serial tunneling”. To do this, you need two serial to Ethernet converters, each connected directly to the serial device. They will need to be configured to talk and listen to each other, but once they are configured, they will efficiently send data between two serial devices as if they were directly connected by a serial cable.
If an application on your PC is designed to communicate directly with a serial device, but there is no serial port available on your PC, you will need to create a virtual serial port, also known as a virtual COM port. It will effectively act as a serial to Ethernet converter locally on your computer, taking your serial data and making it available over a TCP / IP connection. This is often used in conjunction with a serial to Ethernet converter, which takes application data sent by a PC over a network connection and transmits it to the serial device it is connected to.
Steps for connecting a serial port to an Ethernet network
The Serial to Ethernet connector eliminates the need for physical connections when accessing serial devices from your computer. This dedicated software application supports remote Ethernet communication using serial protocols including RS232, RS422, and RS485. Without the need for additional cables, you can control and monitor serial devices over the network using the same functionality as with a direct physical connection.
Here is an overview of the steps required to use RS232 to Ethernet software on your computer.
Download and install the application on the computer that will share the serial port and also on the machine that will remotely access it.
Launch the Serial to Ethernet connector on the host computer that will use the serial interface. Select the “Server” option in the program and, if desired, configure the connection parameters. When the configuration is complete, click Create Connection to make the port shareable.
Launch the Serial to Ethernet application on the computer that will be accessing the serial port remotely and select the Client option to create the connection. Make sure you are using the same hostname and port number that were defined when you created the connection in the previous step, and then click Connect.
With these simple steps, you have obtained a full access connection to the remote device that you can use as if it were directly connected to the client computer.
