How to configureWiz550S2E/Wiz550WEB using WIZnet Configuration Tool


This post introduces the usage of configuration tool for WIZnet Product  Wiz550S2E / Wiz550WEB. This configuration tool provides two ways to configure our product in GUI mode and Command line mode, so users can choose a way depending on their convenience.

For example, if you want to test several functions or changes on a product, then GUI mode would be a better choice. In the other hand, if you want to update same information of multiple products in factory repeatedly, then Command line mode would be much better and convenient.

This post will shows how to use the configuration tool in GUI mode and Command line mode.

Before starting, refer following link for creating runnable jar file for our source code.
