How to Keep Your Outdoor Extension Cords Dry?

The spring is almost here and it’s again that time of the year when we all shall be sitting in our backyards, with a nice cup of coffee, group of friends and dim (yellow) lights till late night!

 

Today people are going crazy over the trend of yellow/white series lights, bulbs, etc. Because they make all the difference to your conventional decorating ideas. But we would have to cope with the weather fluctuations as well. Last two days in our city the weather was rainy. We knew that the weather will be better later on this week, and that’s why we kept my chairs under plastic bags to save them from getting wet.

 

But with the lights, it was a different scenario. We had connected many extension cords together to make the whole set of series work simultaneously.

 

To protect them from rain and keep them dry, we applied one small DIY trick and it worked well!

 

That’s why here we are sharing that with you to help you keep your extension cords dry and protect them from the uncertainty of the weather. There are some other small tips as well at the end of the article.

 

DIY Extension Power Cord Protection Cover:

 

This trick can come in handy when you have outdoor extension cords, probably where the lawn sprinkler pump sits, under wet surfaces like docks. To keep the extension cords plugged-in and dry, you can create a shield with the following steps as mentioned below:

 
  • Purchase the plastic containers and if you have them at home you can also use them, you don’t necessarily need to buy new ones.
  • They are a bit stiff and can be easily set on the ground as a ‘dry box’.
  • Start drilling holes at each end of the container. Make sure the holes are big enough to fit in the extension cord but not too big to let other elements like water enter the container.
  • Take a utility knife(be careful) and cut up the holes as required.
  • Spread the plastic apart with enough space to insert the plug inside the container.
  • Put the top back on.
  • And you are done!

 

Keep your extension cord plugs inside it and the container will protect them from the wet and humid weather.

 

It doesn’t need to be an insane air-tight container. The store-bought version would do just fine. This level of protection is enough. It will work well and keep the power cords off the ground and dry to keep your lights working throughout the season.

 

Pro Tip: Never Use Metal Tape for this.

 

Other Methods:

 

Method: 1

 
  • Take an inner tube and cut about a six-inch piece and place it on the one end.
  • Plugin the tool and place the other half of the inner tube on the other end.
  • And done! It will keep all the water away from your extension cords.

 

Method: 2

 
  • Take a good quality plastic bag.
  • Cover the whole extension power cord and wire together.
  • Make a bunch and place them at your choice of place.

 

User Do’s And Don’ts

 

Don'ts:

 

Apart from the outdoor usage, there are a number of ways you might be using your extension power cords. One needs to be careful while using them to ensure safety. Following are some of the don’ts along with user guidelines:

 
  • If you have cords that aren’t long enough to make it to the outlet, then move that device closer to the location or install a new outlet. This is to ensure safety around the environment. Do not use them if you have doubt about the length of the cord.
  • Never install extension power cords in place of proper electric wiring. Keep them in holes, hidden in floors, ceilings, and walls.
  • To ensure that there is no fire hazard, avoid using them through windows, doorways, and other openings.
  • If possible avoid the tacking the power cords using nails & staplers onto the surfaces and walls. Doing so you might as well give yourself an electric shock.

 

Do’s:

 

If you are following the above-mentioned things, it’s time to change the conventional way and do things differently.

 
  • First and foremost, extension cords are only useful when intended. Use them as a temporary source of power.
  • When using it, ensure that it is completely plugged in. After that, attach it to the device you want to power.
  • To unplug it, take the cord out the outlet.
  • After using it, coil it in a dry and safe location.
  • Inspect the cord carefully for any damages before using them.

 

Extension cords can be a great product to light up your back lawn, garden, or even the insides of your house using your choice of lights. The important thing to keep in mind is to follow the user guideline and keep them dry to avoid any hazards at your home!

HDMI ARC: What is it and Why You Should Care?

If you buy a new TV or soundbar, you might have come across the new label about “ARC” while setting up the HDMI adapters. That indicates one of the best features which saves your money, reduces cable web and makes your set up more simplified.

 

What Is ARC?

 

Ever since the HDMI 1.4 was introduced in the market, ARC is available on TVs, soundbars, and other gadgets. It is a protocol which offers two-way communication between devices over a single HDMI connection. This port lets you use HDMI as both an input and an audio output.

 

It came in 2009 and became a common standard. Majorly you would find it with all types of TVs, soundbars, and receivers. All the devices which support HDMI 1.4 would support ARC.

 

 

Things You Can Do With ARC:

 

It provides a two-way flow of sound means that you can use it for things which require extra cables.

 
  • First and foremost, you will be able to connect your audio system with a single HDMI cable. For that, connect your soundbar to the TV with the ARC-capable port. After that, you can use it for every device that connects with TV. It includes Blu-ray players, game consoles, and other devices. Plus, it does all of these through the TV itself. You do not require a separate audio receiver.
  • You can run the connections mentioned above through the soundbar itself. It allows you to shift the multiple HDMI connections from the TV to the soundbar without any additional setup. In some cases when your TV is wall mounted and you can’t access all of the HDMI ports or simply want a clean look which includes fewer cables, the arc capable ports are perfect. It requires lesser cable installations.
  • ARC system also comes handy when you connect the TV with a soundbar or speaker system. You can also use the ARC connection to deliver audio from the TV to your speakers. Without the HDMI Arc, you will need to go into the TV settings to activate the “Receivers” or “External Speakers”. But with the ARC, it automatically sends the TV’s audio to whatever external device is connected with it.
  • With ARC supported system you can deliver sound to your soundbar without any other connector with a dedicated audio cable.
  • With HDMI-CEC (Consumer Electronics Control) like Blu-ray players or satellite boxes, you can use ARC to reduce both the number of cables used and the number of controls needed for your system.

 

How To Setup:

 

To set up ARC completely with the system, you can follow the steps given in the guidelines below. Depending on the model and manufacturer, it might take some time to activate it.

 

Determine the ARC port on your system. Most TV manufacturers offer ARC output over HDMI port instead of all three or four port on the set. Mostly they try to indicate it with labels. If HDMI adapters ports don’t have proper labeling, check the TV manual. It will help you navigate to the HDMI ARC that you can use.

 

Activate the ARC output on the TV to start leveraging it. You can find this feature in the settings menu under audio. In many TVs, this feature auto-detect devices with ARC capacity. While in others you need to turn on the feature manually.

 

One thing to keep in mind while plugging in your stuff is that ARC-enabled port should be there with your external audio device.

 

Paradoxically…

 

Even our brand-new iPhone model would have some drawbacks. Just like that, the simplicity of ARC and audio over HDMI is viable, but it has some disadvantages as well. The main aim behind designing this stuff was to replace S/PDIF digital audio outputs. Thus, it supports each and every audio format that wouldn’t normally pass through S/PDIF. For instance, Dolby Digital, DTS and PCM audio. It can handle TV’s regular two-channel audio and 5.1 surround sound without any troubles.

 

Even though it replaces the S/PDIF standard, it can’t send HD or high-bit-rate audio with high standards like Dolby Atmos and DTS:X. It can be little overwhelming as the downstream audio over HDMI can carry the signal without any obstacles. This is ARC related disadvantage only which is one of the major limitations of the ARC specifications.

 

Some TVs actually downgrade the audio output over ARC by converting everything to two-channel sound even if it originates as 5.1 audio. Depending on your TV model you might wind up with the lower sound quality even after using ARC. In this case, if you want, you can connect an extra audio cable or two which may cause more trouble for you but will be worth it.

 

The Power Of HDMI ARC

 

In the present scenario, many TVs dumb down and compress audio signals before passing them down to HDMI cables while others do support more channels. Dolby Atmos albeit uses a compressed codec like Dolby digital plus instead of Dolby True HD. Now that requires much bandwidth. But with ARC, you can send the original, full-resolution audio signal via HDMI cables. Which produces the best sound without any compromises.

Cat6A Shielded vs NonShielded: How to Make the Right Choice?

Cat6a cables: an inexpensive solution for 10G cabling. Its design is according to the upgraded design of Cat6 cable. They are capable of supporting data transfer rates up to 10 Gbps at a maximum bandwidth of 500MHz.

 

With the ever-emerging applications and industrial demands, it is a recommended standard for most of the production units. Moreover, they are backward compatible with Cat6 and Cat5e.

 

However, the debate about choosing Cat6a shielded vs unshielded is a dilemma for many users. It is important to understand the difference between them along with the pros and cons. Let’s discuss that in detail.

 

The main thing to consider while installing Cat6a cables is that they are future-proof network products. If you are planning to get a new cabling system, consider Cat6a as the first option. Even if planned for ten years or more, Cat6a definitely appears to be the best solution.

 

 

Considering the Cat6a components in a 10Gbps, class EA network, here’s why they are considered the best solution:

 
  • CAT6A is the best option for Healthcare.
  • CAT6A is considered to be the best option for Education.
  • It provides improved performance for Power over Ethernet (PoE).
  • They support wireless systems which are reliable on 10Gig.

 

Understanding The Difference: Shielded Vs NonShielded

 

Both shielded and unshielded cables differ in design and making. They are chosen on the basis on the industry requirement, connectivity of electronic equipment, etc.

 

Cat6a Shielded Cable

 

Cat6a shielded twisted pair (STP) has shielded cables to prevent electromagnetic interference (EMI) or radio-frequency interference (RFI) that affects the cable performance. They prevent the cable signals from interfering with cables in the surrounding area. These cables contain a special ground wire - drain wire. And one of the best practice for shielded cables is to ground them at both the ends.

 

For high-speed 10G networks, they are an ideal choice. If you install them properly, they automatically curb EMI and crosstalk which ensures the integrity of data and high-speed performance.

 

Cat6a Unshielded Cable

 

Cat6a unshielded twisted pair (UTP) cables do not have shielding but are twisted into 4 sets of pairs. Each bare copper conductor is color coded. Each of the bundle of Cat6a unshielded cable should be under an overall jacket such as PVC, and each pair of cable has a different twist rate in order to minimize crosstalk within the cable. This standard is most common in the market as they are less expensive than the shielded cables. Plus, they are simple to install as there is no shielding or drain wire involved. Although they are less effective to handle EMI, they are larger in size which requires more space for accommodating them.

 

Famous Acronyms Of Cat6a Cable Shielding

 

There are many acronyms describes Cat6 shielded and unshielded cables. Here we are with the basic information about each type of acronym used to clear up the confusion. Although there are many of them used synonymously.

 
  • TP = Twisted Pair
  • U = Unshielded
  • F = Foil Shield
  • S= Braided Shield

 

If we consider the ISO/IEC standards, the first letter indicates the type of overall shield while the next part of the acronym indicates the type of shielding on each pair. For instance, F/UTP, “F” indicates the shielding type, “U” describes the shielding pairs, “TP” describes the twisted pairs. The code before the slash symbol describes the overall shielding. The second letter after the slash indicates the shielding of each pair.

 

After knowing them thoroughly let’s see how you can choose the right cable:

 
  • Consider the Cost: Cat6a shielding cable is expensive compared to unshielded.
  • Installation: Installation of unshielded cables is easy than the shielded one.
  • Environment: Unshielded cables are environment-friendly.

 

Unshielded cables actually provide faster data speed in the absence of EMI. They are less expensive to make a purchase, easy to install and been there in many existing installations for years.

 

Comparison

 

Another important factor to consider while choosing between Cat6a shielded vs unshielded network ethernet cables battle is to analyze how EMI would play the role while installation. EMI can be caused by nearby motors, generators, air conditioners, offices such as light and print shops, etc. They can cause crosstalks between circuits which affect the performance and result in degradation of data, slow data speed, and errors.

 

So, if your area experiences heavy electromagnetic interference, Cat6a shielded cable could be the best fit for your area. Because shielding boosts the reliability and blocks out the interference. If you want these cables for the average home office or as a small business owner, you can consider buying unshielded network ethernet cables.

 

Conclusion

 

Overall the choice is fully based on your requirements, budget, and usage. Make sure you install high-quality cat6a cables to expect a longer life from your cable installation. It will eventually reduce long-term replacement and manpower costs.

 

SF cables offer a wide range of options to build your Cat6a network. We provide products which offer high-speed performance. For more information, you can visit our web store here.

 

How to Keep Your Outdoor Extension Cords Dry?

Learn how you can keep your extension cords dry while you are using them outdoors for your fairy lights setup or even inside your place with these easy and proven tricks.

Why are RCA Cables Necessary in The Wireless Age?

Wireless headphones, wireless chargers, wireless speakers and a whole bunch of other wireless things are here to stay now. ‘Cutting the cord’ is the trend.

 

However, certain products are simply not there yet.

 

If we talk about televisions, even modern day ones that literally roll out of sight, they have to use cables for power, for additional I/O needs, etc.

 

The new age televisions that roll out of sight, or stick to walls like posters, still have to have some way of connecting other devices to them. So, we are nowhere near getting rid of cables altogether yet. The cables themselves have evolved over the years. There are of course cables that are simply audio, like the much controversial 3.5 mm headphone cable. Then there are also solutions for managing both the audio and video, together.

 

So, if we have come this far, why do televisions still have the dated red, yellow and white ports? What is the use of them?

 

Well, those are RCA ports, to which RCA cables connect for audio and video. The yellow connector at the end of the cable is for composite video, the red one, for the right audio channel, and lastly the white one for the left audio channel of stereo sound.

The main purpose of these audio video cables in terms of a traditional television set is to connect a video input device, making the TV itself the audio output device. So if you were to connect a video game console to a standard TV, the console would be the input for the video, the TV would display it, and the TV speakers would provide the sound.

 

But this is the most basic setup, and standard RCA audio video cables are not as updated as one may need them to be. They cannot provide the display in extremely high resolution, which we have come to expect nowadays. RCA audio cables are, however, the analog solution you need if your display lacks the fancy multi-channel HDMI port. You will always find RCA ports saving the day.

 

RCA cables cannot combine multi-channel audio in one cable. Therefore, there is one cable for each channel you may want to add to your set up, including a certain number of subwoofers if that’s your requirement. Anything over four channels and a subwoofer might be too overwhelming for a home setup. However, audio feedback largely depends on the size of the room, the materials it has and how the sound absorption is.

 

One of the requirements of this is when you have limited HDMI ports on your display. The things that you need to connect to a display have increased over time. You probably have a satellite DTH box, a gaming console, a DVD player, a variety of speakers, and lastly a streaming box or stick. When all put together, it requires a minimum of two HDMI ports, a few audio video ports, of various kinds and perhaps even some spare USB ports for a flash drive or an external hard drive.

 

Another requirement that you might have is to set up a high-end home theatre in your house. And here’s how you can do it:

 

  • The main element of a home theatre setup isn’t just a large screen. Proper surround sound is an essential part of the whole experience. You can add multiple speakers, via RCA cables, connect an array of subwoofers and enhance the sound.
  • Adding speakers to a display also has another advantage. If one speaker were to malfunction, you can simply replace that particular channel without having to replace your whole setup. This increases the longevity of a very expensive home theatre system.

RCA Cables were first seen in the 1940s which were introduced by Radio Corporation of America. They didn’t have the idea that their product would last till date.

They might not be the best but they do the work.

 

And in case you were wondering how to connect the RCA cables to HDMI or vice versa, then we have covered that in the next section.

 

HDMI is used for digital signal whereas RCA cables are for analog signaling. To convert the RCA signal to HDMI or vice versa, there needs to be an active signal converter.

 

How to convert or connect HDMI to RCA?

 

  • You can find HDMI cable with RCA connectors on the other end. These look pretty and seems like a perfect solution for a complicated problem, but these cables don’t work at all.
  • There are companies selling HDMI to RCA converters which will do the work you want them to but only if the HDMI signal isn’t encrypted.
  • Then you can also go with HDMI to RCA converters which come with built-in decryption. With these, the problem of HDMI signal encryption goes out of the question.
