Category 5, Cat5, Cat5e, Cat6, wiring diagrams both for straight through cables, crossover cables, token ring cables in RJ45. As a bonus learn how to build a Ethernet Economizer / Splitter.
Straight Through Patch Cable
Crossover Cable
Ethernet Economizer / Splitter
A special cable that allows you split one Ethernet cable into two (limited to 100 Mbps), very useful when you want to connect two devices but you only have one cable.
Note that you’ll need to make two of such cables, one to use at each end. Your final installation with two of those splitters should look like this:
The actual choice of pairs is completely up to you as long as you do the same on each end. Do not split the pairs – this will very effectively kill the signal within short distance. Use at your own risk.
