    Kit Overview


    The tiny-footprint Stellaris® Serial-to-Ethernet Module (MDL-S2EMDL-S2E) offers a complete, ready-to-implement solution designed to add web connectivity to any serial device. The most common application for the MDL-S2E..MDL-S2E.. is for augmenting legacy products that only contain a serial port for a configuration or control interface. In addition, newer computers, especially laptop computers, do not necessarily have serial ports, and a serial connection is limited by cable length (typically 10 m).


    Simply installing a Stellaris® Serial-to-Ethernet Module into the legacy serial device provides many benefits including no major board redesign or software changes, easy sharing on a network other than Ethernet, tiny form-factor for unobtrusive implementation, and 10-meter maximum cable length for serial connections is no longer a limitation.


    The Serial-to-Ethernet (S2E) module is a simple add-on product that provides serial to Ethernet communications. Existing systems that lack Ethernet connectivity but have a UART or RS-232RS-232 port can be easily upgraded by the addition of the S2E module. A web server supports module configuration from any web browser.


    The MDL-S2EMDL-S2E is the first serial-to-Ethernet converter available with a highly integrated ARM® Cortex™-M3 microcontroller with 50 MHz of performance and ample single-cycle, on-chip Flash and SRAM memory for efficient network traffic handling. For maximum space savings, the Stellaris® microcontroller is offered in a small BGA package and integrates the 10/100 Ethernet MAC and PHY on-chip.


    Key Applications: Connectivity, Security, Industrial Automation.
