2.3.4.2 Ethernet Port
The Ethernet Port utilizes a 10Base-T RJ-45 modular connector that typically provides a
shielded twisted pair interface to an Ethernet Hub.
A typical Ethernet Hub provides eight (8) 10Base-T RJ-45 Ports (with Port 8 having the
capability to link to another Hub or to an Ethernet communications port). Both ends of the
twisted pair Ethernet cable are equipped with modular RJ-45 connectors. These cables have
a one-to-one wiring configuration as shown in Figure 2-8. Table 2-7 provides the as-
signment and definitions of the 8-pin 10Base-T connectors.
It is possible to connect two nodes in a point-to-point configuration without the use of a
Hub. However, the cable used must be configured such that the TX+/- Data pins are con-
nected to the RX+/- Data pins (swapped) at the opposite ends of the cable (see Figure 2-7).
