Help on RJ45. If there are only four required signals, what the 4 extra wires used for?

Dunno.. could be 4 separate 0v returns--Light current 03:45, 13 December 2005 (UTC)

I think that the RJ45 cable can be used for different purposes. In most cases, only the four innermost wires are used but some applications use the extra wires. This is true for other telecommunications cables, for example telephones use only the inner two wires of the four-wire RJ10 cable.

Are you asking "Why do 10BASE-T and 100BASE-TX only use 4 out of the 8 wires?" To leave the other 4 wires available for other things. What are those other things? Does Varieties_of_Ethernet#Ethernet_over_twisted-pair_cable and Ethernet physical layer answer your question? -- 03:46, 20 August 2006 (UTC)

External links[edit]

User:Strom removed all links since he probably thought it looked like spam or a link farm. Some were ok. Also I moved an external link from main article to links section. Joakim.Ogren 17:13, 28 December 2006 (UTC)

Too many examples?[edit]

Does anyone else think there are too many examples here? Seems like one would suffice - if a user is looking for a specific pinout they'll look for the page for that connector, not for this page. Should all examples except one be removed, so that this page is about what a pinout is? Thrapper (talk) 11:34, 20 May 2008 (UTC)

I agree. The USB is fairly universal, and gives a good idea of what a pinout is. Kevin (talk) 11:57, 20 May 2008 (UTC)
Get rid of the IVECO stuff which gives no useful info and takes a lot of space, then see how it looks.MarkMLl (talk) 21:59, 25 May 2008 (UTC)
It looks better IMO. Kevin (talk) 22:24, 25 May 2008 (UTC)

electronic components[edit]

I changed the intro to indicate that it is not just for connectors. The wording is horrible so feel free to fix it. The rest should be made more general as well.

As for the examples, I added two. One of an IC in a standard DIP and one of a component in a more traditional case. I'd prefer if the second one was not an IC, perhaps a vacuum tube, if I can find an illustration.

This might be too many examples (as per the section above), but if you remove some of them, I'd think it would be a good thing to keep at least one connector and one component. Bomazi (talk) 20:55, 4 April 2011 (UTC)
