5.2 Ethernet Connectors (IO Area)
The KTQ67/Flex-Medical support two channels of 10/100/1000Mb Ethernet ports, ETH1 and ETH2.
Both ports are Galvanic Isolated. ETH1 (left Ethernet connector) is based on Intel® Lewisville 82579LM
Gigabit PHY with AMT 8.0 support and ETH2 (right Ethernet connector) is based on Intel® Hartwell
82574L PCI Express controller.
In order to achieve the specified performance of the Ethernet port, minimum Category 5 twisted pair
cables must be used with 10/100MB and minimum Category 5E, 6 or 6E with 1Gb LAN networks.
The signals for the Ethernet ports are as follows:
Signal
Description
MDI[0]+ / 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.
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]+ / 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.
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]+ / 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[3]+ / 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.
Note: MDI = Media Dependent Interface.
The pinout of the RJ45 connectors is as follows:
