6.3. Ethernet Connector

The QDS-9400 supports one channel of 10/100/1000 Mbit Ethernet.
In order to achieve the specified performance of the Ethernet port, Category 5 twisted pair cables must be used with
10/100 MByte and Category 5E, 6 or 6E with 1 Gbit LAN networks.
The signals for the Ethernet ports are as follows:

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.
