Roll over cable colour code for rj45 connector?

Answer 1

To know colour coding of cross cable we need to know some basic facts like where it is use and from where we can generate it.The answeres are crossover or we say cross cable is used for connecting similar devices like pc-pc or hub-hub etc,and we can generate it from the basic colour coding of 568a standard.But the question is how?as 568a standard is a standard for twisted pair but itscomes under the subcategory ofunshield twisted pair cable.so,lets come to the main ans,so here we go--

568a colour coding is

green=gr,white=w,orange=or,blue=bl and brown=br(short form)

1.gr/w

2.gr

3.or/w

4.bl

5.bl/w

6.or

7.br/w

8.br

As we can see above the colour coding of 568a cables{straight(use to connect dissimilar devices like pc-hub)}the basicof colour coding.we can generate the colour coding for cross cable from it-

straight cross

1.gr/w3-1 1-3 1.or/w

2.gr6-22-6 2.or

3.or/w 3.gr/w

4.bl4.bl

5.bl/w5.bl/w

6.or 6.gr

7.br/w 7.br/w

8.br 8.br

As we switch 3-1 that is put no.3 of straight in no.1 of cross(from left side)and cancel no.1 that is gr/w,so we get the combination of or/w in no.1 in cross.As we do the others that is

1-3,6-2 and 2-6(from left side)we get the combination for cross.If somebody wants to remember directly he can,but its the alternate method and from the basics.

Answer 3

Rollover cable (also known as Cisco console cable) is a type of null-modem cable that is most commonly used to connect a computer terminal to a router's console port. This cable is typically flat (and has a light blue color) to help distinguish it from other types of network cabling. It gets the name rollover because the pinouts on one end are reversed from the other, as if the wire had been rolled over and you were viewing it from the other side.

This rollover cable is more commonly known as the Yost cable or more appropriately the "Yost Serial Device Wiring Standard".
