Dual-Media Ports
The W-7205 controller is equipped with four sets of dual-media ports (ports 0 through 3). These ports can utilize
either a 1000BASE-X or 10/100/1000BASE-T connection provided. However, the 1000BASE-X fiber connection has
priority over the 10/100/1000BASE-T copper connection. If a link is detected on the 1000BASE-X interface, the
10/100/1000BASE-T connection will be disabled.
10/100/1000BASE-T (RJ-45) Ports
The W-7205 controller is equipped with four 10/100/1000BASE-T copper ports, as a part of dual-media ports.
Gigabit Ethernet uses all eight wires and each pair is used in a bi-directional fashion, meaning the same pairs are
used for both data transmission and reception. Figure 3 illustrates the CAT-5 pin-out on an RJ-45 connector. The
CAT-5 pin-out pairs the following pins on a 10/100/1000BASE-T Gigabit Ethernet port: 1/2, 3/ 6, 4/5, and 7/8.
