The media dependent interface (MDI) standard is typically used for the Ethernet interfaces of network
adaptors. The media dependent interface crossover (MDI-X) standard is typically used on hubs or LAN
switches.
3) RJ-45 connector
The 10/100/1000Base-T Ethernet interfaces of the U200 series use RJ-45 connectors and support
MDI/MDIX autosensing. Category-5 twisted pair cables are used for RJ-45 connectors. Figure 1-11
shows an RJ-45 connector.
