3.5.5 Ethernet Port
Figure 17 shows the pinout for the RJ-45 Ethernet port (header J4 on the RabbitCore mod-
ule). Note that some Ethernet connectors are numbered in reverse to the order used here.
Figure 17. RJ-45 Ethernet Port Pinout
Two LEDs are placed next to the RJ-45 Ethernet jack, one to indicate an Ethernet link
(
LNK
) and one to indicate Ethernet activity (
ACT
).
The transformer/connector assembly ground is connected to the RabbitCore module
printed circuit board digital ground via a 0
resistor, R31, as shown in Figure 18.

on RabbitCore Module
The RJ-45 connector is shielded to minimize EMI effects to/from the Ethernet signals.
