Wiring scheme: EIA/TIA 568B
This cable will work with 10Base-T, 100Base-TX and 1000Base-T and is used to connect a network interface card to a hub or network outlet. These cables are sometimes called "whips".
Note: While 10BaseT and 100Base-TX only uses two pairs, please do connect all pairs since 1000BaseT uses all of them, and save yourself some future debugging :)
(To network interface card).
RJ45 MALE CONNECTOR to network interface card).
RJ45 MALE CONNECTOR to hub).
Note: It's important that each pair is kept as a pair. TX+ & TX- must be in the pair, and RX+ & RX- must together in another pair. (Just as the table above shows).
Just for your information, this is how the pairs are named:
|1||4 & 5||Blue|
|2||1 & 2||Orange|
|3||3 & 6||Green|
|4||7 & 8||Brown|
The + side of each pair is called the "tip" and the - side is called the "ring", a reference to old telephone connectors.
