  • WIZ VSP (WIZnet Virtual Serial COM port) is the software for those users who want to use the existing application programs based on serial communication.
  • WIZnet Virtual Serial Port: It can be used to change the device that is connected to the PC through the existing serial interface to control by the remote Ethernet network.
  • If you agree with the End User License Agreement for WIZVSP, you will be able to download the program and get a registration key. When registering the product with license agreement, the MAC address of the product in use and the Email address of the contact person are required.


  • The latest version supports up to Windows 10, and we recommend using Windows 7 or higher.
  • Environments under Windows 7 support only the old version, if necessary, contact the technical support team.
  • The current WIZVSP driver does not officially support the Windows 11 environment, so operation cannot be guaranteed and technical support is difficult.
    • To use in the Windows 11 environment, you must manually enable the port using the 'Scan for hardware changes' menu in Device Manager.
