2) Making Ethernet cables
You can use category 5 twisted-pair cables to make Ethernet cables. A category 5 twisted-pair cable is
composed of eight wires that are identified and grouped by colors of the outer insulator. Usually a solid
color wire and a white/solid color wire are organized in pairs. But sometimes, wires are also paired by
color dots.
Ethernet cables fall into two categories: straight-through and crossover:
z
Straight-through cable: The wires are crimped in the RJ-45 connectors at both ends in the same
order. The cable is used for connecting a terminal device (for example, PC or router) to a HUB or
LAN switch. The cables delivered with the router are straight-through cables.
z
Crossover cable: The wires are crimped in the RJ-45 connectors at both ends in different orders.
The cable is used for connecting two terminal devices (for example, PC and router). You can make
cables as needed.
z
In making network cables, shielded cables are preferred for electromagnetic compatibility sake.
z
The interface cables in the standard package of RT-FIC-FE modules are straight-through cables.
Connecting the interface cable
Step1 Plug one end of the cable to an Ethernet port on the router and another end to the device to be
connected. (For a PC or router, use a straight-through cable; for a HUB or LAN switch, use a
crossover cable.)
Step2 Power on the router and check the behavior of the LINK LED on the FIC-FE panel: ON means that a
link is present and OFF means that no link is present. In the latter case, check the line status.
Before you connect a port, read its label carefully; a wrong connection can cause damages to the
interface module and even the device.
FIC-1GBE/FIC-2GBE
Introduction
FIC-1GBE/FIC-2GBE, the 1-port/2-port 10Base-T/100Base-TX/1000Base-T Ethernet electrical
interface module, is used for router-to-LAN communication.
The modules support:
z
100 meters (328.1 ft.) of transmission segment over the category-5 twisted-pair cable.
z
Operation at 1000 Mbps, 100 Mbps, and 10 Mbps, auto-sensing.
z
Half-duplex/full duplex, autosensing
