4.9. Ethernet (P26)

The SBC-FitPC2 provides one Gigabit Ethernet port implemented using a Realtek

RTL8111x Gigabit Ethernet controller.

The RTL8111x offers data transmission over a CAT 5 UTP or CAT 3 UTP (10Mbps only)

cable. Functions such as Crossover Detection and Auto-Correction, polarity correction,

adaptive equalization, crosstalk cancellation, echo cancellation, timing recovery and error

correction are implemented to provide robust transmission and reception capability at high

speed. The RTL8111x is compliant with IEEE 802.3u specifications for 10/100Mbps

Ethernet and IEEE 802.3ab specifications for 1000Mbps Ethernet.

The RTL8111x is fully compliant with Microsoft® NDIS5, NDIS6 (IPv4, IPv6, TCP,

UDP) Checksum and Segmentation Task-offload (Large and Giant send) features, and

supports IEEE 802 IP Layer 2 priority encoding and IEEE 802.1Q Virtual bridged Local

Area Network (VLAN).

The Ethernet interface is available through standard RJ-45 connector P26.
