2.6.2.4. J10 : Ethernet
Since there is KSZ8041NL PHY in Eddy-S4M module, when integrating Ethernet, just connect
RJ45 in which transformer located
WARNING : When you use RJ45 which has transformer in its internal circuit, it is possible to
each product doesn’t have equal PIN spec. Therefore, you must confirm PIN number
Bellow is KSZ8041NL functions
• Fully compliant to IEEE 802.3u Standard
