Any modern business is going to be networked with Internet connections. Whether a business is in a small home office with a single computer and printer or an enormous building with hundreds of machines, a nervous system of cables and wiring will be essential to keep things running smoothly. When cables go missing or start to fail, losses in both productivity and profitability are sure to follow. Most homes have a drawer filled with spare cables and there is no reason that an office should not do the same thing, albeit with better organization than a junk drawer.
The modern mobile phone is a pocket-sized electronic more powerful than the machines used to put astronauts on the moon. Among their many other features, these compact computers are great for streaming music, movies, and TV shows. But sometimes you want to put those streaming services on the big screen. Exactly how you can go about doing that will depend on what type of phone you have.
*Note: These tips also work for other handheld devices like tablets.
Different types of cables have different functions and it is easy to view any cable as a single, working unit. But each cable is made of different layers, with each layer providing a different function. Learning how these pieces interact makes it easier to understand just how a cable works and what can be done to avoid damaging a cable.
Coax is one of the most common types of cable, having been in use for well over 100 years. While the technology has improved over time, the basic layout
“Pinout” is a term describing how an electrical cable is wired. Some cables do not have pinouts because they only contain a single internal wire, like coax cables. But if a cable has multiple pins on the end of the cable, it will have a pinout.
Each type of multi-pin cable has a standard pinout or two, but these layouts are not set in stone. Some machines will require non-standard pinouts; this will require users to use a custom cable.
Pinouts also come into play when using a cable with two different ends. For example, going from DB9 (9 pins) to DB25 (25 pins) will mean the DB25 side has 16 unused, “dead” pins.
If you need to know what pinout a cable needs, ideally there will be a spec sheet h
Anyone who has ever used a desk or wall phone knows they all have one problem in common: cords getting tangled. In the long run, it does not particularly matter how careful or gentle you are with a coiled handset cord. Eventually, the cord is going to end up as a jumbled mess. Preventing a cord from tangling in the first place is where a detangler comes in.
Phone cords do not last forever. When a cord starts to tangle, the smaller wires inside the cord
Modern telephone cords have been in use for a long time, with little change since their invention in the 1970s. Finding phone cords in the store can be tricky today; many stores have stopped carrying telephone cables since so many people only use cell phones now. This rings especially true for coiled handset cords. With these cables becoming rarer, sometimes it is better to repair rather than replace them. Other times, users may just need a cable not available in a standard length.
There is a bit of variation with different connectors available, as well as different wiring schemes (called
Telephone cords are one of the more basic types of cables. Phone cables have remained mostly the same over the years with a few small changes here and there. There is a little terminology to know that will tell you a bit more about your phone lines, such as how they are wired and what type of plastic connector is on the end of the cable.
Phone cords come in two varieties, flat cords used to connect phones to the wall and coiled cords used for handset receivers. Flat cords will use either an RJ11 or RJ12 connector. These two connectors are the same size and look the same on the outside. On the inside, RJ11 will have four metal contacts for the internal wires inside the cable while RJ12 has six contacts. Since they are the same size, RJ12 is backwards compatible with RJ11. However, since RJ11 is the older of the two it is not compatible with RJ12.
