I'm trying to figure out how ethernet works on the arduino ethernet shield, and I'm having trouble figuring out the connections on the board. The connector doesn't have a standard pin out since it's POE, and a google search for the datasheet only brings up Chinese retailers, but no datasheets. Can anyone help me out? I've checked the schematic, but I have a few questions lingering that would be cleared up if I can figure out how the w5100 hooks up to the rj 45 connector. Thanks!
What do you need to know that you can't learn for the schematic and board layout?
I think the connector part is RS3-16401D1A from UDE-Corp.
