    Why such an odd color combination for pins 1, 2, 3, and 6 ?

    I've seen several variations of the A and B schemes. There's nothing to say that that pins 1 and 2 have to be green/Green White. It's just important that you be consistent between ends of the cable. However, I did pull out an old RJ45 jack that is color coded to the B spec, and it does the Green pair on 1/2 and orange on 3/6.

    You'll notice that the only difference between A and B is the swapping of the positions of the Green and Orange pairs. The 3/6 combination is due to the way that Cat-5 is spec'd and how the pins are used to transmit things like Ethernet.

    Wow, I thought the color change was because they looked better together and were more relaxed. The version A looks too stuffy.

    I wonder that Dan Baldwin intended the B version to be for running the power supply + and -. The B version would certainly lend itself to better noise rejection. I'll bet Dan liked the colors better for B version too. The B version is better color coordinated at least for the wires that matter.

    Since some people use 4 wire telephone wire for their controllers, is probably why only pins 3, 4, 5 and 6 are used when the RJ-11 is plugged into the RJ-45 jack

    I am wiring both ends of the Mighty Mini (1 - spot light waterproof socket and 2 - keystone inside the controller case) to the "B" standard. I see it won't make any difference as long as the cable that I use is wired the same on both ends .. which certainly they all should be ...

    I noticed that the keystone jacks that Al purchased for us, all have the color code on the side - - showing both "standards." I would like to ask the boneheads why they changed the standard .. and then still called their new one "standard." I guess that's like semi-boneless ...

    If I remember right, the A standard is used in the telecommunications industry (developed back in the old days), and the B standard is used in the computer / networking industry. These days it seems that there is very little difference between the two as most telecommunications now runs on computer networks

    It's probably because someone needed to define a "cross-over" cable and just called one end the "A" end color pattern and the other the "B" end color pattern. Most normal residential-grade data communication equipment doesn't operate at the speeds of the commercial stuff, and can autoselect if pins 1 and 2 are transmit and 3 and 6 are receive, or vice-versa. Much of the higher-end equipment can't use auto-negotiate, or gives you the opportunity to turn it off, as 1 gib/sec Ethernet tends to screw up doing auto-negotiate, so the cable has to be correct at the get-go.
