4.2.2 Ethernet PHY
All RCM5700/RCM6700 models have an Ethernet PHY, which can either be accessed through
the Interface Board or directly on the RCM5710/5760/6710/6760. The PHY connections or inte-
grated 10/100Base-T connections on MiniCores with an on-board RJ-45 jack are via 0 jumpers
on headers JP2–JP5 (see Table A-6 in Appendix A.3). Rabbit’s Technical Note TN266, PCB Lay-
out for the Ethernet PHY Interface, provides further details about designing your own PHY
interface.
The pinout for the RJ-45 Ethernet jack (J1) is shown in Figure 4-11. Note that some Ethernet con-
nectors are numbered in reverse to the order used here.
The RJ-45 Ethernet jack incorporates green and yellow LEDs, one to indicate Ethernet link (
),
LINK
and one to indicate Ethernet activity (
).
ACT
The RJ-45 connector is shielded to minimize EMI effects to/from the Ethernet signals.

4.2.3 Programming Port
The RCM5700/RCM6700 programming port is accessed via the USB connector (J5) on the Inter-
face Board. The programming port uses the Rabbit CPU’s Serial Port A for communication.
Dynamic C uses the programming port to download and debug programs.
The programming port is also used to cold-boot the Rabbit processor on the RCM5700/RCM6700
after a reset.
