COM over Network
Access and share COM port over Network

COM to Ethernet Connector is a product that will conveniently let you share as many as 500 COM port devices through internet or local area network (LAN). Regardless of how many COM ports your computer has: with a Serial to Ethernet Connector your computer is capable of delivering data to dozens of COM ports and the respective serial devices connected to it.
Also available on Linux OS and Windows Mobile

For Developers

Sign up for the API evaluation program and test Serial to Ethernet Connector integration into your own software product.

Share serial port over network

Even in the event that the shared COM port hardware is located on the other side of the globe, you will have the means to use it as if it was hooked up to your computer.

  • Sharing COM Port for Inbound Connections (Server)

    The server connectivity will be ready and waiting for incoming client signals and as a matter of fact will share a local real or virtual COM port over the network. It provides the power to hook up numerous clients all in one go. Each client will transmit input/output COM data to their local real or virtual serial port. The Serial to Ethernet Connector by default connects these data channels on the server. The client can be any kind of application that can initialize an outbound connection to a TCP/IP server, for example, Telnet.
  • Connecting COM Port to a Remote Host (Client)

    Creating the client connection will trigger a local real or virtual COM port data redirection to the remote host server by using the TCP/IP protocol. This type of connectivity does not need to have SEC presence at the remote part. All that the user has to do is designate the remote server's IP address and the TCP port to connect to. It also works by specifying the network name. Once the link is up and running, all information sent from the remote side, is instantly sent to the local COM port where it can be dealt with further.
  • Share COM port using UDP

    Users can redirect any input/output data from the local real or virtual COM port by using UDP/IP as their transport protocol of choice. This form of interconnection does not call for SEC presence at the remote side. What's more, in this scenario users can broadcast all COM port data over a local network.

    In summary, a Serial to Ethernet Connector lets users select the data transmission protocol: RAW data transmitting algorithm or Telnet (RFC 2217) communications protocol.
  • Serial to Ethernet Connector for Linux OS is available

    COM port over ethernet app 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 Serial to Ethernet Connector for Linux is a command-line product at the moment.

What customers say
    • 4.9
    COM to Ethernet Connector worked perfectly for us. The product has worked exactly as expected, simply and with no fuss. Now we can access the Hardware Security Modules from our test system as if it is local. It also saved us a lot of money!
