How To Build Own Console Cable

    Went down to the local electronics store and bought a ribbon cable and an
    RJ-45F to DB9F adapter.

    But now that I'm looking at documentation, I'm confused. As best I can
    tell, BOTH wires 4 and 5 from the ribbon cable have to go to pin 5 on the
    DB9. However, the leads are already clamped firmly on the wires. There is
    no way I can possibly cut the lead off, splice the wires, and then get the
    lead back on.

    I just want to make sure I'm reading this correctly. Do I really need to
    splice wires 4 and 5 to pin 5 on the DB9?

    Thanks

    The both are grounds. Its good to have ground, although in reality,
    you can probably have one or the other be ground, and everything will
    pick it up correctly.

    What I normally do when doing what you are doing is snip off the
    crimped on pin, strip the wire, carefully strip some of the wire off
    the other ground wire, and twist together. A little heat shrink tube
    should be fine, or electrical tape (which won't hold very well on such
    little wires).

    All of Cisco's cable sets are custom made, and they have both wires
    crimped onto the pin in the shell or under the molded hood.

    I found the best way is to use DB-9/DB-25 to RJ45 adapters. Use the
    cisco supplies ones or buy kits and pin out the same as the cicso ones.

    By using the various adapters and either a rolled cisco cable with the
    RJ-45 on each end, or a straight wired LAN cable with all four pairs can
    adapt to almost anything. a couple of gender changers helps also.
