Crossover Cables vs other cables?

[mp3blast]

wats the difference between crossover cables and CAT5 cables? do they do different things? there both ethernet though..anyways im just wondering cause im starting a home network

[Charles Wirth]

cat 5 cable has 8 wires

pins 1,2,3,and 6 are used

1 and 2 are pairs, 3 and 6 are pairs.

when you strip back the cable you will notice 4 pairs twisted together.

O range, G reen, Br own, B lue

get rid of 2 pairs/ 4 wires to avoid confusion. I just cut off brown and green pairs.

Ok take the solid orange and run it to pin one and orange/white wire to pin 2

take the solid blue and run it to pin 3 and take the blue and white wire and run it to pin 6

If you were to do this same procedure on both ends you would have standard cat 5 ethernet cable(non gigabit)

If you wanted to make a cross over cable you would switch the blue pair and the orange pair at one end only.
Crossover
Pin 1 2 3 6
B BW O OW
O OW B BW

Standard
Pin 1 2 3 6
O OW B BW
O OW B BW

To make this cable a cat 6 cable you would need to connect all 8 pins

Standard
Pin 1 2 3 4 5 6 7 8
O OW B G GW BW Br BrW
O OW B G GW BW Br BrW

Crossover cables can connect 2 computers together without a hub or link 2 hubs together that do not have a uplink switch/port.

cool thanks for the info

i need to connect a comp to a router, so i should get a cat5 cable right?

thanks

A normal (non-crossover) Cat5 cable is what you need.

[Ulfar]

comp to comp = cross over; and comp to router = normal... , its all the same cable its just how the ends are crimped that matters.

Depends on what type of router you are using. Most low end routers (linksys, dlink ect) use a standard straight thru cable.

Other high end routers like cisco use x-over cables because they are actually like pc's.

oh cool thanks

Damn Fug. Could you get a little more detailed there?;)

going by the 568a and b standards...

os= orange stripe
o=orange
gs= green stripe
b= blue
bs=blue stripe
g=green
br=brown
brs=brown stripe

568 B:
os o gs b bs g brs br

568 A:
gs g os b bs o brs br

Patch cable= 568B on both ends
Crossover= 568B on one end, A on the other.
This is looking down at the connector, on the side without the "snap thingy"
