  • Page 14: Using Sec (Serial-To-Ethernet Connector)

    Using SEC (Serial-to-Ethernet Connector) Introduction Serial to Ethernet Connector is an advanced software-based solution that allows you to share more than 255 serial port devices over network easily turning your computer into low- cost terminal server. Thus, any serial port device connected to your COM port could be accessed from anywhere in the world (via Internet or LAN) as if it is attached directly to the remote PC.
  • Page 15 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 serial port device, attached to the server, will be genuinely delivered to local serial port where it can be further processed.

  • Page 16: Driver Installation

    Driver installation 1. Double click SDS_Setup in order to start installation process. Note: This driver combines the utilities of Serial to Ethernet Connector and Serial to Ethernet Toolkit. Both utilities will be installed to the computer after running the installation. 2.
