Transmission of RS232 Data Over Ethernet

Devices with RS232 serial ports can send serial data over wired or wireless Ethernet when connected to a LAN (Local Area Network) using an RS232 to Ethernet converter. Provides reliable data transfer to other devices and network server applications by converting RS232 data signals to Ethernet packets (TCP or UDP) and vice versa. To do this, RS232 data is encapsulated into Ethernet packets depending on the type of data being delivered.

An RS232 to Ethernet converter has one or more RS232 serial ports on one side and a physical wired or wireless (LTE or Wi-Fi) network connection on the other side. Essentially, when you connect to a network-connected device, the connection works as if you were physically connected to the RS232 port with a direct cable. This is ideal for M2M communication as client access needs to be independent of proprietary operating systems and protocols. To secure network data transfer and device access, it is generally recommended to use a converter with advanced security features such as data encryption and user authentication, although simpler ones are also available. increase.

First known as RS232, this standard was developed in the 1960s to define electrical signals between a communication device and the computer to which it is connected. Standard bodies revised the standards and the nomenclature changed when EIA merged with TIA. RS232 is the most common name, but EIA/TIA232 is the most recent and accurate. Ultimately, they all follow the same standard to specify the interface between data terminal equipment (DTE) and data circuit-terminating equipment (DCE) using serial binary data transmission.
