SEGGER embOS/IP Switch Board 6.70.00 embOS/IP Switch Board

The embOS/IP Switch Board is intended to be mainly a demonstrator board for the Tail Tagging add-on of SEGGER's embedded IP stack embOS/IP. Micrel / Microchip has developed switches which can expand one physical port into 1+n ports, supported by the so-called Tail Tagging mode. This enhancement allows to establish multiple physical external ports when only one physical Ethernet port is available on the CPU - by choosing another PHY. The embOS/IP Switch Board provides a solid starting point for a project that requires multiple physical Ethernet ports by using SEGGER’s middleware products. SEGGER’s embOS real-time operating system is at the heart of the evaluation. Furthermore, an evaluation version of the TCP/IP stack embOS/IP (including web server demo and UPnP) enables full evaluation of multi interface solutions. The embOS/IP Switch Board also features a J-Link OB, an on-board version of SEGGER’s market-leading debug probe J-Link. There are three Ethernet ports that can be accessed individually by software although they share the same host interface by using the embOS/IP Tail Tagging add-on. Each of the Ethernet ports can have its own hardware address and identified by the network as individual host. The embOS/IP Switch Board is powered by USB only. Current consumption drawn strongly depends on the application and connected Ethernet links. Idle consumption is approx. 140 mA.
