2.2 Connect the Ethernet Interface
The EFM Router has four unshielded RJ-45 auto-MDIX10/100Base-T interfaces. These
are designed to connect directly to a 10/100Base-TX network.
Figure 6
shows the sig-
nal/pin relationships 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.
