Today we going to disccuss about an RJ45 to connect to Internet
The
cable for network card comes in two types. One with Shilded pair type cable
with BNC pins. These are common cables found to connect two or more Win9x
machines with lesser efforts and easy installations with BNC type Ethernet
cards.
And another most faster in data-transfer is RJ45 type cable with eight (8) cores of wires with RJ45 pins. We are talking about this second type of Network cable. The pins on RJ45 are counted as follows.

IMP NOTE: The new Ethernet Card with both types of connectors,
i.e., BNC and RJ45 is called combo-card. The Ethernet cards come with
SETUP-DISK which helps you to toggle between the BNC and RJ45 interface
setting. Old ethernet cards came with jumpers to do this task, but
nowadays, the jumperless Ethernet Cards are needed to be set to RJ45 or BNC
type through the SETUP program disk given with it. These SETUP programs do
write on the NVRAM chip on the card. Read the README.TXT of such SETUP-DISKS or
Card's MANUAL for more information. Also most important thing to keep in mind
is that you need to setup the card with free I/O-port and free IRQ number of
your system which are assigned to the card through that SETUP program of the
card. For example, TYPE:RJ45, PORT:320, IRQ:10, etc. Please do not ask me
further about this that I may not answer in this section further even though I
do setup these cards perfectly everytime. Actually this needs more
practical experience than theory. You may find the appropriate sites
elsewhere on this subject on Internet.
The
pinout I am giving is not any special kind but simply a straight parallel pins
cable to connect any network system in FEMALE SOCKET of the NETWORK HUB. With
compatible softwares this cable is both for 10Base-T and 100Base-TX cards. In
simple words the MALE RJ45 PIN is inserted directly into Ethernet Cards of a a
Network Computer which may be either a SERVER of a WORKSTATION to the NETWORK
HUB.

NOTE: Both sides
of RJ-45 (cat-5) cable should have the same Color-codes as given above, only
then it is called straight network cable. Remember pin 1 and 2 are on one
color pair. 3 and 6 are on second color pair of wire. These colors are
technically approved and standardized set for straight RJ45 cat5 cable. But the
color codes of the wires become irrelevant when you connect right number pin to
right wire from pin to pin. Also its not guaranteed that you will get the
perfect colored cores of cable in your city/area. Anyway this is straight
cable, so no need to think much about it. Connect all pins straight with
crimping tool even though the descriptions for some pins are not given as they
are not used for common data transfer but for some other internal signaling.
Believe me its not worth knowing for or may be I don't know. ;-)
To
avoid the expensive hub unit when only two systems are to be connected to each other
directly at Ethernet Cards with this cable called Crossover Cable. With
compatible softwares this cable is both for 10Base-T and 100Base-TX cards. This
MALE RJ45 PIN is inserted directly into Ethernet Cards of both the Machines.
100Base-Tx uses 4 wires
(2pairs) to transmit data against the 100Base-T4 cable which uses all 8 wires
(8pairs). Etherenet 100Base T4 is generally works at nearly 100mbps with
standard 100mbps HUB. But it works at nearly 200mbps with Network Switch
(Extended Version of HUB).
