  1. DB9 Connector Pinout

    When building or repairing DB9 cable assemblies many customers request a DB9 connector pinout reference drawing in order to determine where each conductor of the cable should be terminated to. There are several primary types of DB9 connector pinout schemes that we will review in  blog post.

     

    Key Takeaways

    • A DB9 connector is a nine-contact D-sub connector commonly used for serial and control applications.
    • DB9 and RS-232 are not the same thing; DB9 identifies the physical connector, while RS-232 identifies a communication interface.
    • Always verify the DB9 connector pinout before wiring or replacing a cable.
    • Male and female DB9 connectors have different physical contact configurations.
    • Straight-through and null modem cables use different wiring configurations.
    • TXD, RXD, and GND are important signals in common RS-232 DB9 applications.
    • Not every DB9 connector follows a standard RS-232 pinout.
    • OEM equipment may use custom DB9 pin configurations for communication and control.
    • Correct connector

  2. RJ11 to RJ45 Wiring Diagram

    Adapting an RJ11 to an RJ45 Cable: A Practical Guide

     

    Using an RJ11 to RJ45 wiring diagram is the best way to convert from the 8-positon RJ45 to a 6-position RJ11 connector. In today's rapidly evolving technological landscape, the need to adapt and repurpose existing equipment is becoming increasingly common. In this blog post, we will explore the steps required to successfully adapt an RJ11 to an RJ45 cable.

     

    Key Takeaways

    • RJ11 and RJ45 are not interchangeable simply because they use similar modular connectors.
    • RJ11 is commonly associated with telephone and voice applications.
    • RJ45/8P8C connectors are widely used for Ethernet networking.
    • Always verify the RJ11-to-RJ45 pinout before creating or purchasing a cable.
    • A physical connection does not guarantee electrical or network compatibility.
    • Check the number of conductors and required signal assignments.
    • Always confirm the connector's viewing orientation when following a wiring diagram.
    • Do not assume that an RJ11-to-RJ45 connection can

  3. Get Your Desk In Order

    Your desktop shouldn’t cause you stress. But if you have a ton of cables getting in your way, chances are you start to feel frustrated by the end of the day. With products like Sugru on the market, the days of stray and inconveniently placed cables are behind us. In this post, I’ll show you a few ways that I streamlined my desktop’s cables.

    Before getting to work, you can see how messy my desk was. Underneath the desk was really the worst of it, especially since my feet could easily get caught on a cable. To start, here’s what I grabbed.

    1. DVI-D Male Dual-Link Cables

    2. USB 2.0 A Male to A Female Active Extension Cable

    3. 3.5mm Stereo Male to Female Extension Cable

    4. 6 Port USB Desktop Charger

    5. 1 1/4 Inch Magnetic Bridle Rings (3)

    6. LEGO mini-fig

    7. 1 Inch Cable Tie Mount Pad

    8. LEGO bricks

    9. Super strong magnets

    10. Sugru

    11. Nylon cable ties

    To move my tower from the center of my desk to the right side, I grabbed longer DVI cables. I also used Sugru to mount a USB hub to my cubicle
