6.3. Ethernet Connectors (I/O area)

The mITX-SKL-S/H110 supports two 10/100/1000 Mbit Ethernet ports.
In order to achieve the specified performance of the Ethernet port, Category 5 twisted pair cables must be used with
10/100 MByte/s and Category 5E, 6 or 6E with 1 Gbit/s LAN networks.

Description
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.
In MDI crossover mode, this pair acts as the BI_DB+/- pair,
and is the receive pair in 10Base-T and 100Base-TX.
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.
In MDI crossover mode, this pair acts as the BI_DA+/- pair,
and is the transmit pair in 10Base-T and 100Base-TX.
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.
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.
