Note
The development board provides a reference design of a POE (Power Over
Ethernet) power supply. A schematic for this reference design is installed by
the setup program on the CD.
Connectors: Ethernet Interface
The Ethernet connector is an 8-wire RJ-45 jack that meets the ISO 8877 requirements for
10/100BASE-T. See the following figure and table for pin orientation and pin assignments.
Note
Pin orientation and assignments are the same for modules with or without a
JTAG connector.
