/products/devtools/single-board-computers/b/blog/posts/ethernet-lan-interface-unitHello,Does anyone acknowledge the electric circuit below or recognize the protocol type which usually make use of the 48 pin connector ? Any information about is welcomed !

So the protocol is &#39;ethernet&#39;. You can trace the wires from the Ethernet jack to the transformer, and from there to the connector (I think then transformers are connected 1:1).</p><img src="https://community.element14.com/aggbug?PostID=2695&AppID=82&AppType=Weblog&ContentType=0" width="1" height="1">
