Ethernet is a popular computer networ-
king technology for local area networks
(LAN). Systems communicating over
Ethernet divide a stream of data into
individual packets called frames. Each
frame contains source and destination
addresses and error-checking data so
that damaged data can be detected
and re-transmitted. EasyMx PRO
™
v7
features standard RJ-45 connector
which enables microcontrollers that
support Ethernet communication to
establish a connection with a computer,
router or other devices. All four ethernet
lines (TPOUT+, TPOUT-, TPIN+ and
TPIN-) are routed directly to the MCU
card socket and cannot be accessed via
PORT headers. Additional signalization
LEDs are available on the board.

In order to enable ethernet LEDs,
you must place J12 and J11
jumpers. This connects the LEDA
and LEDB lines to PF2 and PF3
microcontroller pins.
