Slightly OT: Networking Issue

A ha! Did your friend actually do the crimping of the RJ-45s?

David,

Cat5 cable has 8 conductors, 4 of which are actually used for an Ethernet connection – 2 transmit, and two receive. If you don’t use the right color order on the pins, but are consistant with the connectors on either end, the cable will work – there is an electrical connection from the correct pin to the correct pin, but since Ethernet uses a balanced pair for both transmit and receive, it is important that the balanced signal is sent down the same twisted pair in order to cancel out common mode interferance. If you use the wrong color order, you might have one leg going down one twisted pair, and the other leg going down another. If you happen to have T and R signals going down the same twisted pair, there is further potential for crosstalk, which is made worse with higher frequencies (GigE) and longer lengths.

The correct color order is readily available online – Google it (or maybe Bing it ;>)

That loud sound you just heard was the sound of me rolling on the floor laughing.

I forgot, what were we talking about?

BTW, my cable making days are over. I’m going to buy pre-made, pre-tested cables from now on. Life is too short…
