    I'll be buying more of these. Instead of using a clumsy pin inserter, just push the pins into their proper sockets, and lightly pull the pins from the other side with needle nose pliers until they click into place. Don't bend or squeeze the pins too tightly. You'll be done in under a minute!
    Here's what my pinout was.
    RJ45 - DB25 pins
    1 - (blue)
    2 - (orange)
    3 - (black)
    4 - (red)
    5 - (green)
    6 - (yellow)
    7 - (brown)
    8 - (white)

    Pros: - Inexpensive
    - Good quality
    - Works well

    Cons: - None

    This adapter comes with the connector unpinned, so you can configure the pins/wires to fit your configuration. The wire coloring is consistent between the adapters Monoprice sells, so if you use a standard ethernet cable, the colors will be connected (e.g. orange on one adapter will be connected to orange on the other).

    Pros: looks good, like it should work

    Cons: The RJ-45 part is NOT pinned. You have to pin it out yourself. Perhaps I'm just missing where it specifies it, but I don't see anything anywhere that states that you have to do the pin-out yourself. When I asked the online support people, they don't know the answer. I would have hoped for a chart or something. If you know what the pin-out should be, it's not a problem, I'm sure, but if not, you're apparently out of luck

    not bad, but not great either

    Thank you for your review. And I apologize for the inconvenience you have had with this item. I have gone ahead and filed a complaint in regards to this PID, but if you prefer you can try a replacement to see if that will work better or if you are unsatisfied with the item; I can help you set up an RMA for a return. Our items do have a lifetime warranty for non-electronics and cables and a 1 year warranty for electronics. If you want to continue with the RMA just please provide me the order# and if you wanted to return it or obtain a replacement. Thank you!

    That's ok, I'll try to figure out the information that I need, it was just frustrating. The fact that whoever answered my query on chat wasn't able to get me that information or advise if one of the pictures that you have online is actually pinned correctly or not was disappointing. I was willing to do it myself and still am, I just need the information. I'll check elsewhere online and see if I can determine the info that I need. Thanks
