Ethernet connectors.

The KT690/mITX boards supports 2 channels of 10/100/1000Mb Ethernet RTL8111B LAN controllers.
In order to achieve the specified performance of the Ethernet port, Category 5 twisted pair cables must be
used with 10/100MB and Category 5E, 6 or 6E with 1Gb LAN networks.
The signals for the Ethernet ports are as follows:
Signal Description
MDI[0]+ In MDI mode, this is the first pair in 1000Base-T, i.e. the BI_DA+/- pair, and is the transmit
pair in 10Base-T and 100Base-TX.
MDI[0]-
In MDI crossover mode, this pair acts as the BI_DB+/- pair, and is the receive pair in
10Base-T and 100Base-TX.
MDI[1]+ In MDI mode, this is the second pair in 1000Base-T, i.e. the BI_DB+/- pair, and is the
receive pair in 10Base-T and 100Base-TX.
MDI[1]-
In MDI crossover mode, this pair acts as the BI_DA+/- pair, and is the transmit pair in
10Base-T and 100Base-TX.
MDI[2]+ In MDI mode, this is the third pair in 1000Base-T, i.e. the BI_DC+/- pair.
In MDI crossover mode, this pair acts as the BI_DD+/- pair.
MDI[2]-
MDI[3]+ In MDI mode, this is the fourth pair in 1000Base-T, i.e. the BI_DD+/- pair.
In MDI crossover mode, this pair acts as the BI_DC+/- pair.
MDI[3]-
Note: MDI = Media Dependent Interface.
