For 10BASE-T/100BASE-TX connections, a twisted pair cable must be used.

Each pair is identified by two different colours. For example, one wire might be

red, and the other red with a white stripe. An RJ-45 connector must be fitted to

both ends of the cable. Figure 6 illustrates the pin layout for RJ-45 connectors.

With 10BASE-T/100BASE-TX cables, pins 1 and 2 are used for transmitting

data, while pins 3 and 6 are used for receiving data. Table 4 lists the RJ-45 Pin

assignments.

1. The “+” and “-” signs represent the polarity of the wires that make up each wire pair.
