The green led is fixed, and signals the correct connection of the module. The yellow led blinks when there is
activity (data IN/OUT) on the net connection.
With RJ45 connectors, only twisted pair cables can be used.
Important Note. Connection to a 100BASE-TX hub for 100 Mbps operation requires the use of
Cat.5 Unshielded Twisted-Pair (UTP) cable or Cat.5 Shielded Twisted-Pair (STP) cable. The
maximum length between the 100BASE-TX hub and the adapter is 100 meters. Connection to a
10BASE-T hub for 10 Mbps operation requires a Cat.3, 4 or 5 UTP cable or Cat.5 STP cable. The
preferred maximum cable length between the CPU module and the Ethernet adapter is 10 cm
(4”)
