How to Transmit RS232 Data Over Ethernet?

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.

Ethernet:

Robert Metcalfe and his colleagues at Xerox PARC developed the Ethernet communication protocol in 1973 to connect computers on a network via a wired connection. All wired networks, including home, business, and bank networks, can be Ethernet LANs. Most desktop and laptop computers have built-in Ethernet cards that allow you to connect to your Ethernet LAN out of the box.

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.

RS232 to Ethernet Converter:

RS232 to Ethernet Converter installation is recommended if you have to:

• While maintaining the use of the devices that were active on the serial network, replace the RS232 serial cabling with Ethernet.
• Connect a PC or server to distant serial devices over Ethernet, and configure virtual COM ports.
• Communicate through a network with numerous serial devices at once.
• Delete any serial dial-up modem connections currently in use.
• Use Ethernet or out-of-band connections to control the serial console port on servers, routers, switches, PBXs, firewalls, etc.
• Serial PLCs and serial signage devices should be connected to the Ethernet.

RS232 to Ethernet Converter Applications:

Installing an RS232 to Ethernet converter is ideal for:

• Replace RS232 serial wiring with Ethernet, but keep using devices that were active on the serial network
• Set up a virtual COM port to connect your PC or server to a remote serial device over the Ethernet.
• Communicate with multiple serial devices simultaneously over a network
• Replace an existing serial dial-up modem connection
• Manage serial console ports on servers, routers, switches, PBXs, firewalls, etc. over Ethernet or out-of-band connections.
• Connect your serial PLC or serial signage device to Ethernet.
