3.4 CONNECTING THE 10/100BASE-T ETHERNET INTERFACE
The unshielded RJ-45 port labeled
Data
on the EHA2168 model is the
Auto-MDIX10/100Base-T interface. This port is designed to connect
directly to a 10/100Base-T network. Figure 4 shows the signal/pin rela-
tionships on this interface. You may connect this port to a hub or PC
using a straight through or crossover cable that is up to 328 ft long.
