RabbitCore RCM3750
4.2.2 Ethernet Port
Figure 8 shows the pinout for the RJ-45 Ethernet port (J3). Note that some Ethernet con-
nectors are numbered in reverse to the order used here.
Figure 8. RJ-45 Ethernet Port Pinout
Two LEDs are placed next to the RJ-45 Ethernet jack, one to indicate an Ethernet link
(LINK) and one to indicate Ethernet activity (ACT). A third LED (SPD) on the other side
of the RJ-45 Ethernet jack indicates that the RCM3750 is connected to a functioning
100Base-T network.
The RJ-45 connector is shielded to minimize EMI effects to/from the Ethernet signals.
4.2.3 Serial Programming Port
The RCM3750 programming port is accessed through header J2 or over an Ethernet con-
nection via the RabbitLink EG2110. The programming port uses the Rabbit 3000’s Serial
Port A for communication. Dynamic C uses the programming port to download and debug
programs.
The programming port is also used for the following operations.
Cold-boot the Rabbit 3000 on the RCM3750 after a reset.
Remotely download and debug a program over an Ethernet connection using the
RabbitLink EG2110.
Fast copy designated portions of flash memory from one Rabbit-based board (the
master) to another (the slave) using the Rabbit Cloning Board.
Serial Port A has special features that allow it to cold-boot the system after reset. Serial
Port A is also the port that is used for software development under Dynamic C.
Alternate Uses of the Programming Port
All three clocked Serial Port A signals are available as
a synchronous serial port
an asynchronous serial port, with the clock line usable as a general CMOS input
