Serial over IP
Share and access your serial port over IP Network

Serial to Ethernet Connector with a completely new interface and a revamped engine is a software-based solution that allows you to share up to 500 serial port devices over TCP/IP network, effectively turning your computer into a low-cost terminal server. As a result, any serial port device can be made accessible from anywhere with Serial over IP technology.

Also available on Linux OS

Share up to 500 serial port devices over TCP/IP network

Serial over IP Connector creates a server connection on a real COM port and client connections on remote machines’ virtual COM ports. The device connected to a real COM port will easily exchange data with multiple remote computers.

  • Easy way to share serial devices over network

    Serial to Ethernet Connector is based on virtual serial port technology and lets you access devices located on the remote PC as if they were plugged into your own computer. Applications using such remote devices treat them as local ones.

    For example, to share a serial device over Ethernet you need to install Serial to Ethernet Connector on both sides of the connection (client/server), thus establishing a "serial tunnel": on the server side, Serial to Ethernet Connector converts serial data into TCP/IP data and hooks it over Ethernet to the client side, where Serial to Ethernet Connector converts TCP/IP packages back into serial data.
  • Extended configuration options

    You can easily modify communication port parameters even without reopening ports, ports are automatically configured every time upon booting your computer, and customize the serial port's connection parameters (baud rate, parity, data bits, stop bits, and flow control).
  • High compatibility

    Serial to Ethernet Connector is fully compatible with Windows 2000/XP/2003/Vista/2008/7/8/10 (including 64-bit editions). It can run on Hyper-Threaded and multi-processor systems and even under Virtual Machine (VMware, VMware ESX, Microsoft Hyper-V, etc.).

    Moreover, using Serial to Ethernet Connector, which supports the RFC 2217 Telnet extensions for COM Port Control, you can easily connect to a remote computer using the TCP/IP Telnet 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 Serial to Ethernet Connector for Linux is a command-line product at the moment.

What customers say

  • Serial over TCP/IP technology turns dreams into reality! It's very easy to configure even for someone who knows nearly nothing about connecting machines. Thanks to SEC I forgot about serial to ethernet connection problems.
