    For wiring up a phono jack to the RJ12 plug it doesn't really matter, but this image shows the pin numbers on the plug:

    The pins 6 to 9 that you can't see are numbered: 6 on the right to 9 on the left.

    Looks like you updated your original post with pin locations on the phono jack. Thanks!!

    Yes, I edited it within 30 seconds of posting it. However, the forum sends out the emails with the original text not the edited tetxt.

    I read it right here on the forums. I must have caught it immediately after you posted it then. I'm like white lightning.

    That is what i did with the efilive cable i made... it has the pins inverted already. so it should owrk like a charm.. hence the swapping 2-3.

    Excuse my ignorance, but is the mono 3.5mm jack on the plx controllers a std serial stream? If so this would also apply to them if im not mistaken?

    RJ12 is numbered 6 on the left and 1 on the right when holding the plug with the gold pins facing you and facing upwards.

    LC-1 phono jack, has ground at the base, pin 3 at the tip and pin 2 in the middle.

    Remember to cross 2 and 3 so that you will end up with:

    RJ12 pin 2 goes to phono base
    RJ12 pin 5 goes to phono middle
    RJ12 pin 6 goes to phono tip


    Regards

    This post is confusing to me. Your description of which pin numbers are which is right. But the part in bold isn't right. Given the pin numbering layout, you have it reversed. It should read.

    RJ12 pin 5 to phono base.
    RJ12 pin 2 to phono middle.
    RJ12 pin 1 to phono tip.

    I verified this buy lookin at the supplied RJ12 to RS232 end. Only RJ12 pins 1,2, and 5 are used. I think you just got the order mixed up.

    Here is how I tested it out. I used the supplied cable from the EFI live, the supplied cable from the LC-1. Here was my logic.

    RJ12 RS232 RS232 Phono
    pin 1 pin 2 pin 2 middle
    pin 2 pin 3 pin 3 tip
    pin 5 pin 5 pin 5 base

    Swap pins 2 and 3 between the RS232s and you end up with

    RJ12 Phono
    pin 1 tip
    pin 2 middle
    pin 5 base


    Can you please confirm my suspicisous are right. I want to make sure I'm not overlooking something.

    You're right, I got the pins mixed up on the RJ12.
    They are "officially" numbered 1 to 6 from left to right - when looking at the exposed pins in the plug and holding the plug pins facing up.

    See image.

    Ok, now its clear. I found a source that showed the opposite. Either way, I'll just make sure they're in the right location regardless of number. Fantastic illustration!
