Ethernet to Serial Web Server Module

The Ethernet to Serial Web Server Module is designed to provide a TCP/IP access to the serial data. This embedded serial web server module can also be plugged directly on LinkSprite PLC-UART power line communication module to act as a power line to web server bridge. Because it’s a serial server, a configurable static IP address is used to prevent IP address being changed. The module is configurable through the convenient AT commands. It is based on the Wiznet W5100 ethernet chip.
