HDMI Uncensored: Triangle Cables Read of the Month!

Aug 27, 2012

HDMI couplers
Whether you’re an end-consumer or project lead, HDMI connections are often confusing and downright complex. Confusion is unfortunate since HDMI applications have radically altered the home/office/security/entertainment interface. Connections are possible in ways you only dreamed about a few short years ago, but making the connections requires a lot more than an HDMI coupler or two.

President of DPL Labs Jeffrey Boccaccio brings HDMI to a level anyone can understand it with the help of Derek R. Flickinger from Interactive Homes, Inc. in “HDMI Uncensored.” You’ll soon have your colleagues and clients impressed with your ease of speech on the mysterious applications of HDMI female to female connections, CEC, TMDS functionality, EDID, HEAC attributes, and the entire reasoning behind the analog to HDMI switch.

If it sounds intense, end-use readers need not be concerned. Boccaccio writes for the layman even while introducing new terms and commands. Even if you’ve previously confused an HDMI coupler, for a Chinese finger trap, you’ll catch on fast and have fun doing it. When you are ready to take integration to the next level, unlock the secrets of HDMI female to female and other strange interactions take a read through “HDMI Uncensored.” We sure have enjoyed it!


Bayonet Neill-Concelman connector: Just What is a BNC Connector?

Aug 23, 2012


Whether you are a ham radio operator or establishing a closed-circuit video surveillance system, chances are your wiring needs go further than the reach of standard coaxial cables. A BNC connector is useful in any analog communication and audio-video networking application. As a replacement for traditional coaxial connectors, the Bayonet Neill-Concelman connector allows a wider frequency range with degradation of signal and is a standard choice for cable termination.

The benefit of a tighter connection makes BNC connectors a good choice in other applications with more exacting needs. High-tech video networks benefit from their use. Other applications include testing equipment for electronics, commercial and military aviation electronics, and serial analog interface.

The primary difference between BNC and other connectors is the tightness of connection. Instead of providing a cross-sections of wire, BNC uses a pin to enter the conducting wire for maximum area. The external ring locks into place with a quarter turn. A more recent version of the connector is threaded for attachment and deeper penetration, which extends frequency capacity above 3 Gigahertz.

Establishing a network requires the best equipment. You don’t want to lose power due to sub-standard connectors. The BNC connector is graded for most coaxial cables under 500 volts.

How to Diagnose an Internal Jack Problem

Aug 20, 2012

Diagnosing an internal phone problem is not easy, but there is a method for isolating damaged equipment.

Most problems can be fixed on your own with significant savings, but first you must determine whether the problem is in fact yours to fix. Take a working phone to the phone line jack located in the company’s gray box outside the structure. If it doesn’t work, contact the phone company for repairs on their end.

If it does work, it’s time to isolate the problem to a specific jack, phone line splitter, or phone cables. Is every phone out of service? If so, this suggests a problem in the wiring. If only one phone is effected, try a different one in the outlet. If this works, the problem is with the phone, and the phone cable is likely to blame.

If the problem is specific to the jack, remove the phone line splitter or other equipment to isolate only the jack. Damage is far more likely with splitters and exposed wiring. Hidden wiring is difficult to replace without help. If you can’t identify the problem, and the phone attached to the phone line jack works, it is necessary to contact a professional.


How to Make your HDMI Couplers and Cables Purchase

Aug 9, 2012

The rapid rate of technological advances in both video and sound makes amazing things possible with home theaters. These advances come at a cost. It is often difficult to find the right connections and interfaces for different brands. A few standards do exist, such as HDMI. For high-definition applications, you need HDMI cables, and an HDMI coupler comes in handy in many situations.

With only one standard and many retailers, some try to make their cables sound better than others. Also, many cables and HDMI female to female couplers are made overseas, which leads to misleading descriptions of the product.

Follow these two basic rules when purchasing cables for your system.

Backward Compatibility

HDMI cables are all compatible with older high-definition equipment. This means that purchasing newer cables provides increased and longer-lasting compatibility. Standard HDMI is perfect for most applications. If you are pushing the pixels necessary for streaming BluRay, you’ll need a high-speed HDMI cable with Ethernet.

Avoid Gimmicks

Cables cannot be infected with a virus or parasite. A cable really is a cable. Standard cables will not lose bandwidth over an HDMI female to female coupler, so you don’t need high-speed cables for standard applications. You may need an HDMI coupler to extend reach, but bandwidth of existing equipment is the only variable worth considering.
