Table 3 summarizes the possible parallel port pins for the serial ports and their clocks.
Remember that the Parallel Port D pins are available only on the RCM4310.
4.2.2 Ethernet Port
Figure 8 shows the pinout for the RJ-45 Ethernet port (J2). Note that some Ethernet con-
nectors are numbered in reverse to the order used here.
Three LEDs are placed next to the RJ-45 Ethernet jack, one to indicate Ethernet link/activity
(
network (
duplex mode (steady on) or that a half-duplex connection is experiencing collisions (blinks).
The RJ-45 connector is shielded to minimize EMI effects to/from the Ethernet signals.
