The pinout is always the same for Ethernet cables.įiber Optics Training Straight Through LAN Cable Pinout It doesn’t matter if you make up some Cat5e, Cat6, and Cat7 cables. The following are the pinouts for the RJ45 connectors so you can check which one you have or make up your own. Most modern communications equipment can auto-sense which type you are using, but some still need the correct cable pinout. This data has been collected from Data Comunicatin Book.Ethernet LAN cables can come in two types – Crossover or Straight through. If you want to connect same type of equipment u will use this crosover cable. If you wnat to connect two diffrent type of equipment u will use this straight cable. any how as for as ur question concern I got some material on it.īasically the straight cable connectons are same on both ends means Now do this(if possible): connect cross cable between swithch and PC and see what happens.! So note that use cross cable to connect two simmilar devices.

If you use HUB or switch, then straight cable will work because it has internal arrangemnt like cross cable. Purpose of this cross cable is RX(reciving terminal) connects to TX(transmitting) of one pc to another PC and Vice versa.Īs we use two PCs (same devices), straight cable will connect TX to TX and RX to RX of two computers, so cross cable is required. In cross cable connectivity is like as follows In straight cable connectivity is like as follows It dosen't matter what colour is given to the cable (but there is a standerd). Right now just forget about colour codes.

This cable (either straight or cross) has total 8 wires (or u can say lines), i.e 4 twisted pairs (4x2=8) with differnt colour codes. Now days, LAN card has intellegence, so that both cables can work.īut, Main differnce between straight and cross cable is connectivity between one RJ45(at one end) to second(other end).
