Serial over Ethernet

Serial to Ethernet Connector is a solution that will easily let you share up to 500 serial port devices over network (Internet or LAN) and access serial port over Ethernet.
Serial to Ethernet Connector

Access serial port over Network

It doesn't matter how many serial ports you have: with Serial to Ethernet Connector your computer can have dozens of serial ports with serial devices connected to it. Even if the shared COM port device is physically in the other part of the world you will be able to access it as if it was connected to your computer. When the attached serial port device sends communication data, it is actually transmitted over TCP/IP network and back from the network to your serial device.

  • Share serial port for incoming connections (Server)

    Server connection will be waiting for incoming client connections and actually will share local real or virtual serial port over network. Server connection provides the ability to connect many clients simultaneously and each connected client is able to transmit input/output serial data to their local real or virtual serial port while Serial to Ethernet Connector automatically joins these data streams on server. Client can be any application that can initialize outgoing connection to TCP/IP server (SEC, Telnet, etc).
  • Connect serial port to remote host (Client)

    Creating client connection will initiate local real or virtual serial port data redirection to the remote server using TCP/IP protocol. Client connection does not require SEC presence at the remote side. All that you have to do is specify remote server's IP address (or network name) and TCP port to connect to. Once connection is established, all data sent from remote end, will be immediately delivered to local serial port where it can be processed further.
  • Share serial port using UDP

    You can redirect input/output data from local real or virtual serial port using UDP/IP as a transport protocol. This type of connection does not require SEC presence at the remote side as well. Besides, in this way you can broadcast all serial data over your local network.

    Serial to Ethernet Connector lets you select data transmission protocol, which will be used for connection: RAW data transmission algorithm or Telnet (RFC 2217) protocol.
  • Serial to Ethernet Connector for Linux OS is available

    Serial to Ethernet Connector is also available for Linux OS! Now you can choose whether Linux or Windows OS will be a client or a server; broadcasting over UDP is possible too. Note, that Linux version is a command-line product at the moment. Download Serial to Ethernet Connector for Linux OS now!

    Linux version for ARM-based devices is available. Now you can share serial ports on ARM devices or connect to remote devices. You are welcome to request an evaluation copy of this version here.
    Note: you need D-Bus to be installed on your device to use this version.
