Figure 24 Ethernet cable

Connector
Ethernet cables fall into the following two categories:

Standard cable: Also called straight-through cable. At both ends of a standard
cable, wires are crimped in the RJ-45 connectors in the same sequence. A
straight-through cable is used to connect a terminal (for example, PC or router) to a
Hub or LAN Switch.

Crossover cable: At both ends of a crossover cable, wires are crimped in the RJ-45
connectors in different sequences. A crossover cable is used to connect a terminal
(for example, a PC or router) to another terminal. You can make crossover cables
as needed.

NOTE:
See Table 7 when distinguishing between or preparing these two types of Ethernet cables. When
preparing Ethernet cables, follow the chromatogram provided in the table to arrange the wires.
Otherwise, communication is affected even if the devices at both ends are connected.
