4.2.2 Ethernet Port (RCM3200 only)
Figure 8 shows the pinout for the RJ-45 Ethernet port (J4). Note that some Ethernet con-
nectors are numbered in reverse to the order used here.
User’s Manual
Three LEDs are placed next to the RJ-45 Ethernet
jack, one to indicate an Ethernet link (
indicate Ethernet activity (
when the RCM3200 is connected to a functioning
100Base-T network (
The transformer/connector assembly ground is con-
nected to the RCM3200 printed circuit board digital
ground via a ferrite bead, R42, as shown in Figure 9.
The RJ-45 connector is shielded to minimize EMI
effects to/from the Ethernet signals.
