2.3.1.2 LAN: Ethernet Connector
UNO-247 is equipped with two Gigabit LAN controllers. An RTL8111G-CG Ethernet
controller is used as the controller chip. The Ethernet port is a standard RJ-45 jack.
Additionally, LED indicators are provided on the front of the device to indicate the
system's Link (off/green/orange) and Active (green) status.

RJ45 Pin Signal Description
1 MDI0+  In BASE-T: Media Dependent Interface[0]:
 1000BASE-T: In MDI configuration, MDI[0]+/-
corresponds to BI_DA+/- and in MDI-X configu-
ration MDI[0]+/- corresponds to BI_DB+/-.
 10BASE-T and 100BASE-TX: In MDI configura-
tion, MDI[0]+/- is used for the transmit pair and
in MDIX configuration MDI[0]+/- is used for the
receive pair.
