Ethernet and Fast Ethernet RJ-45 Connection Equipment

The RJ-45 port on the I/O controller is configurable for 100 Mbps full-duplex or half-duplex
(half-duplex is the default) and supports IEEE 802.3 (Ethernet) and IEEE 802.3u interfaces complaint
with 10BASET and 100BASETX specifications.
The RJ-45 port supports standard straight-through and crossover Category 5 unshielded twisted-pair
(UTP) cables (refer to
are available commercially.
