18. ETHERNET ID STICKERS (BACK SIDE): The numbers on the two stickers are
used to form the unique Media Access Control (MAC) addresses used by the
Ethernet transceivers to identify and filter packets. The number is the base 10
version of the last 6 hexadecimal digits of the 12-digit MAC address. The
board’s full address is formed by appending the number on the sticker to the hex
prefix “00:04:A3” (Microchip’s MAC address prefix). For example, the sticker
number, “12345”, represents 003039h; the full MAC address for the board is
thus “00:04:A3:00:30:39”.
One of these is assigned to the PIC18F97J60 and the other to the ENC28J60.
These MAC addresses are provided for evaluation purposes; both addresses
can be changed in software.
