FIC-1GBE/FIC-2GBE 149Figure 171 Ethernet cableMaking 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 bycolors of the outer insulator. Usually a solid color wire and a white/solid color wireare organized in pairs. But sometimes, wires are also paired by color dots.Ethernet cables fit into two categories: straight-through and crossover.■ 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 (forexample, PC or router) to a HUB or LAN switch. The cables delivered with therouter are straight-through cables.■ Crossover cable: The wires are crimped in the RJ-45 connectors at both ends indifferent orders. The cable is used for connecting two terminal devices (forexample, PC and router). You can make cables as needed.n In making network cables, shielded cables are preferred for electromagneticcompatibility sake.The interface cables in the standard package of RT-FIC-FE cards arestraight-through cables.Connecting the InterfaceCableStep 1: Plug one end of the cable to an Ethernet port on the router and anotherend to the device to be connected. (For a PC or router, use a straight-throughcable; for a HUB or LAN switch, use a crossover cable.)Step 2: Power on the router and check the behavior of the LINK LED on the FIC-FEpanel: ON means that a link is present and OFF means that no link is present. Inthe latter case, check the line status.c CAUTION: Before you connect a port, read its label carefully; a wrong connectioncan cause damages to the interface card and even the device.FIC-1GBE/FIC-2GBEIntroduction FIC-1GBE/FIC-2GBE, the 1-port/2-port 10Base-T/100Base-TX/1000Base-T Ethernetelectrical interface card, is used for router-to-LAN communication.The cards support:■ 100 meters (328.1 ft.) of transmission segment over the category-5twisted-pair cable.
