The EOM-104 series Ethernet switch modules are designed for device manufacturers who would like to embed an Ethernet switch module in their products to enhance performance and reliability. The EOM-104 series modules provide an easy and cost-effective integrated solution for adding an Ethernet switch module to an existing product. The modules support 10/100M Ethernet transmission and comes with Turbo Ring's fast recovery time of under 20 ms built in. The EOM-104 series also provide a rich set of peripherals, such as Turbo Ring Enable and GPIO programming pins, and is an ideal solution for embedded Ethernet applications.  

Evaluation Kits
The EOM Evaluation Kit includes an evaluation board, power adaptor, software CD, and serial and Ethernet cables to allow quick and easy evaluation of all embedded Ethernet switch functions. The evaluation board is equipped with Ethernet ports, console port, and Turbo Ring DIP switch to help you test your modules and applications.
