Selecting The Web Interface

By selecting the Web Relay interface you will be accessing web pages that are built into the module to control the relays.  Boards on this page are equipped with a Web-i communications module that adds Ethernet communications to the board with built-in web pages.  The board will plug directly into your router where it is assigned an IP address or you can set a static IP.  Once the IP address has been assigned you can access the web pages using any browser!
