How to connect(wire) ethernet?

I have a FRDM-KL46Z and NucleoF401 and am trying to connect them via ethernet. Following the mbed wiring instructions is confusing as there is no RX+/- or TX+/- pins, just a RX and TX pin. How do you connect/wire on these boards?

Hi Marcus!

I think this should show you that these two boards don't have an Ethernet MAC (and no PHY) on board/chip! (The RX+/- and TX+/- are balanced bit stream outputs for the ethernet transformer/connector.)

The RX/TX lines are (presumbly) serial lines (UART). But you may use these to connect the two boards nevertheless... (It's even less difficult ;-)

You have to connect a external ethernet controller. See http://mbed.org/components/WIZ550io/ or http://mbed.org/components/Seeed-Ethernet-Shield-V20/ or switch to a platform with ethernet on board.
