Start crimping , make a cut:

Start crimping , make a cut Use the cutting blades of crimping tool or a cutter to make an incision at 2/3 cm from the cable's end.

Untwist &Down flat wires in right order from left to right:

Untwist &Down flat wires in right order from left to right 1 white/orange 2 orange 3 white/green 4 blue 5 white/blue 6 green 7 white/brown 8 brown To build a "direct" cable, both cable's ends must be in this order i.e. All the wires are connected straight through.

Crossover cable:

Crossover cable To build a "crossed" cable, one end like the one above, the other end as the following: 1 white/green <-[1] 2 green <-[2] 3 white/orange <-[1] 4 blue 5 white/blue 6 orange <-[2] 7 white/brown 8 brown Thus in a crossover network cable, wires 1, 2, 3, and 6 are crossed over.

All wires cut at the same level:

After cutting the wires, we insert them into the connector like this. :

Pins 4, 5, 7, and 8 aren’t used as they are not actually needed for network data communication. It means that if needed, we can run two nodes by single cable but this will spoil the quality of crimping. :
