Ethernet cableAs shown in the following figure, the Ethernet cables for FIC-FE cards are category-5twisted pairs with RJ-45 connectors. Pins 1 and 2 of the interface are used fortransmitting data, and pins 3 and 6 are used for receiving data.Figure 3-23 Ethernet cableII. Making Ethernet cablesYou can use category 5 twisted-pair cables to make Ethernet cables. A category 5twisted-pair cable is composed of eight wires that are identified and grouped by colorsof the outer insulator. Usually a solid color wire and a white/solid color wire areorganized in pairs. But sometimes, wires are also paired by color dots.Ethernet cables fit into two categories: straight-through and crossover.z Straight-through cable: The wires are crimped in the RJ-45 connectors at bothends in the same order. The cable is used for connecting a terminal device (for
