3.3.1
Ethernet connector
On board, there is a Gigabit Ethernet connector, for the direct
connection of the UDOO x86 module to a wired LAN.
The Ethernet connection is managed by a dedicated Realtek RTL8111G
Gigabit Ethernet controller, interfaced to PCI-express port #2.
This interface is compatible both with Gigabit Ethernet (1000Mbps) and
with Fast Ethernet (10/100Mbps) Networks. They will configure automatically to work with the
existing network.
Please be aware that it will work in Gigabit mode only in case that it is connected to Gigabit
Ethernet switches/hubs/routers. For the connection, cables category Cat5e or better are
required. Cables category Cat6 are recommended for noise reduction and EMC compatibility issues, especially when the length of the cable is significant.
G/GBE_MDI0-: Ethernet Controller Media Dependent Interface (MDI) I/O differential pair #0. It is the first differential pair in Gigabit Ethernet mode, and the
Transmit differential pair in 10/100 Mbps modes.
G/GBE_MDI1-: Ethernet Controller Media Dependent Interface (MDI) I/O differential pair #1. It is the second differential pair in Gigabit Ethernet mode, and
the Receive differential pair in 10/100 Mbps modes.
G/GBE_MDI2-: Ethernet Controller Media Dependent Interface (MDI) I/O differential pair #2. It is the third differential pair in Gigabit Ethernet mode; it is not
used in 10/100Mbps modes.
G/GBE_MDI3-: Ethernet Controller Media Dependent Interface (MDI) I/O differential pair #3. It is the fourth differential pair in Gigabit Ethernet mode; it is
not used in 10/100Mbps modes.
