Access RS232 over Ethernet
RS232 to Ethernet Connector

RS232 to Ethernet Connector allows you to remotely access any number of serial ports connected to serial devices. Using this RS232 communication software you can access shared COM port devices as if they were physically connected to your computer, even if they are actually located on the other side of the globe. Attached serial port devices transmit and receive communication date remotely by sending the transmission from RS232 over IP, enabling network connectivity. You can also access the data coming from RS232 over Wi-Fi by using this application.
Also available on Linux OS

Share RS232 devices over Ethernet

Easily share up to 500 serial port devices over the network using RS232 over Ethernet Connector. This solution enables network connections by accessing RS232 over LAN or Internet.

  • Share serial port for incoming connections (Server)

    Server will be idle and ready for incoming client connections and will share local physical or virtual RS232 ports to the Internet. The server connection enables connecting multiple clients simultaneously. The connected clients can transmit input/output serial data to local real or virtual serial ports. RS232 to Ethernet Connector joins these data streams automatically on the server. Any application that can initiate an outgoing connection to a TCP/IP server can be the client and connect the RS232 ports via Ethernet.
  • Connect serial port to remote host (Client)

    Creating a client connection initiates data redirection from local virtual or real serial ports to the server by means of the TCP/IP protocol. The presence of the software at the remote end is not necessarily required for the client connection. Simply specify the IP address or network name of the remote server and the TCP port you want to connect to. Data sent from the remote device is immediately delivered to the local serial port for further processing after the RS232 to Internet connection is established.
  • Share serial port using UDP

    Redirection of input/output data is possible using RS232 to UDP communication from your local real or virtual serial ports. Connections of this type also do not need SEC presence at the remote end, and this method allows you use your local network to access all broadcast all serial data.

    RS232 to Ethernet Connector allows to choose the transmission protocol, supporting connections using either the RAW data transmission algorithm or the Telnet (RFC 2217) protocol.

  • RS232 to Ethernet Connector is available for Linux OS

    Linux OS is now supported by Serial to Ethernet Connector! You now have a choice to employ either a Linux or Windows OS as your client or server, with an option to broadcast over UDP. At this time the Linux version is only available in a command-line version of the software.

Other features worth mentioning

RS232 to Ethernet Connector includes other related options that improve the functionality of RS232 over Ethernet sharing.
Send and receive RAW data
The RAW data transmission protocol can be selected for your connection. Using this method of transmission, all data is transmitted with no protocol-specific or application-layer formatting performed.
Change RS232 port parameters remotely
Using the Telnet protocol (RFC 2217) enables the server and client to exchange COM port configuration. They also have the capacity to alert the remote host of setting changes and the line status of the local COM ports.
Works as Windows service
RS232 over Ethernet Connector runs as a Windows service. Therefore, on system startup and before user login, all connections are automatically reconfigured. Your RS232 to LAN connections will be persistent, allowing you to close the application’s interface safely after configuration is complete.
Smart data sending
You can control the data flow over your RS232 over network connection by applying specific, user-defined settings. One example would be to insert pauses between network packets. You can also allow data to accumulate in a buffer for predetermined amount of time, or until a specific size is sent before transmission, among other options.
