Serial to Ethernet Connector
Access remote serial port over Network

It doesn't matter how many serial ports you have: with Serial over 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.
Also available on Linux OS and Windows Mobile

Share serial device over Ethernet

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

  • 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 Ethernet. 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.
  • 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.

Other features worth mentioning

Serial to Ethernet Connector offers various concomitant options that refine and take COM port to Ethernet sharing to the next level.

Send and receive RAW data

You can select RAW data transmission protocol, which will be used for the connection. During a raw serial over TCP session, all data will be transmitted as it is sent, without any protocol-specific application-layer formatting.

Change COM port parameters remotely

With the Telnet protocol (RFC 2217) the server and the client are able to exchange the COM ports configuration and have the ability to notify the remote host of any changes in the settings or the line states of the local COM ports.

Works as Windows service

Serial over Ethernet Connector runs as a Windows service. This ensures that all connections are automatically reconfigured on system boot, before user login. In addition, that means that the interface can be safely closed after configuring all settings, and all your serial to LAN connections will be still maintained.

Smart data sending

Apply settings that will help you control the way the data is sent over the serial to network connection. Add pauses between the network packets or accumulate data in a buffer for a specific amount of time or until it reaches a specified size before being sent, etc.

What our software is capable of
Throughout its long history, our software has helped a lot of people to solve a variety of tasks and problems of absolutely different kinds. And here are some of them:
We have a limited quantity of instruments in our quality control laboratory. The instruments are connected to computers via serial ports. To avoid constant relocation and re-calibration of the appliances we decided to resort to Serial to Ethernet Connector, and now every employee has an access to any instrument at any given time.

Ellen Bishop, Pollution Control Engineer

Our engineers have integrated Serial to Ethernet functionality into the oil rig machines’ diagnostic software, so service personnel can detect any issues that affect the system’s state. In this way, diagnostic and predictive measures can be performed and provided to field personnel so that they can concentrate their efforts on the drilling operation instead of maintenance procedures.

William Newman, Efficiency Engineer

In a nutshell, I was looking for a way to map a COM port with a TAPI device attached to it to a client Citrix XenDesktop session. Since TAPI devices could not be mapped to client COM ports in XenDesktop, my attention was drawn by Serial to Ethernet Connector. The app allowed me to forward the COM port to a virtual environment over the network.

Ted Robertson, Communications Engineer

High safety standards are a must in our research facility, so we demand the same from the software that is used in our work. Password authentication and traffic encryption offered by Serial to Ethernet Connector are the features that distinguish it from any other solution on the market and exactly what we have chosen it for.
