How do I know which cables to use?


There are a handful of cables that transmit both audio and video signals. For years, coaxial video cables were one of the only choices for connecting video components. Coaxial video cables have that famous one-pin connector, sometimes called a stinger, that can either be pushed or screwed into place. Coaxial video cables are now mostly confined to outside connections, such as satellite TV or cable TV lines that come through the wall. A single coaxial cable carries both video and audio signals.


HDMI cables are an updated version of DVI. HDMI cables were also designed for use with HD components, but their connector is much slimmer, like a large USB cable. HDMI also includes HDCP copy protection. Manufacturers of HDMI cables tend to advertise their product as the only choice for connecting HD video components, but that's not true. DVI cables work equally well. However, if you're using an analog TV, all three work equally well [source: Cobalt Cable].


In Europe and the UK, the most popular dual-purpose cable is called SCART (Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs). SCART cables have fat, 21-pin connectors. In Europe, SCART cables do the work of RCA analog audio cables as well as composite, s-video and component video cables, but they can't carry high-bandwidth digital video or audio signals, such as those necessary for high-definition TVs. HDMI is the preferred cable in Europe for HD components.


FireWire, or IEEE 1394, cables are mostly associated with connecting devices to computers, but a few high-end home theater receivers and HDTVs now come with FireWire ports. FireWire is capable of carrying compressed MPEG-2 video and digital audio. You might use a FireWire cable to connect a digital video camera directly to your home theater system to show off some unedited footage.


To sum up, here are the cables that you would use for some common home entertainment systems.


Home stereo system (CD changer, stereo receiver, speakers):




Lower-end: If you're playing regular CDs or MP3s, you'll only need RCA analog audio cables and speaker wire.




Higher-end: If you want crisper digital audio, go for optical or digital coaxial cables and thicker speaker wire.




Highest-end: If you want the unparalleled sound of DVD-audio in full surround sound, you'll need special DVD-audio cables and 12-gauge speaker wire.




Cable


Alternatively referred to as a cord, connector or plug, a cable is one or more wires covered in plastic that transmit power or data between devices or locations. The picture is an example of what the power cord may look like for your computer or monitor. The power cord is one example of thousands of other cables found in and around computers.


There are two main types of computer cables, a data cable and a power cable. A data cable is a cable that provides communication between devices. For example, the data cable (i.e., DVI, HDMI, or VGA) that connects your monitor to your computer allow it to display a picture on the monitor. Other popular examples of data cables include the CAT5, IDE/EIDE, SATA, and USB cables. A power cable is any cable that powers the device. For example, the power cord that connects to your computer and a Molex style cable inside the computer are both good examples of power cables. Below, is a listing of the most common types of cables found with computers and electronics and examples of devices that use them.


What is a Wiring Harness?


The wiring harness has been our core business since 1987. Sumitomo Electric Wiring Systems designs and manufactures the highest quality and most reliable wiring harness products for the automotive industry.


A wiring harness is an organized set of wires, terminals and connectors that run throughout the entire vehicle and relay information and electric power, thereby playing a critical role in “connecting” a variety of components. Power and information travel through this network much like the circulatory and central nervous systems of the human body.


As cars continue to provide advanced functions, their component parts increasingly require electronics to save space and meet other requirements. Experts at efficient design and configuring complex circuits, SEWS creates wiring harnesses that contribute tremendously to the development and advancement of car manufacturers around the world.


Medical Cable Assemblies Information


Medical cable assemblies are designed to connect medical and laboratory instruments and equipment. They transmit power and/or data and usually have an abrasion-resistant jacket that provides relatively low surface friction and mechanical durability. Many are designed with a high degree of flexibility to avoid kinking, and temperature-resistance to withstand autoclave sterilization. Some are disposable.


Like other cable harnesses, medical cable assemblies consist of individual cables that are banded into a single unit with connectors on at least one end. Medical cables typically comply with application-specific safety and regulatory standards, however, such as ISO 10993-1 for the biological evaluation of medical devices. If the outer jacket of a medical cable assembly will come into contact with a patient’s body, buyers should select products where biocompatible materials are used.


Types


There are three major categories of medical cable assemblies: equipment and sub-assembly interfaces, communication interfaces, and patient interfaces.


Equipment and sub-assembly interfaces are installed as original equipment and generally replaced only in case of retrofits or upgrades. Often, this type of cable assembly is used with nuclear imaging devices.


Communications interfaces use fiber optic, modular local area network (LAN), or serial cables. RS-232, RS-422, RS-423, and RS-485 cables are all used in medical applications.


Patient interfaces consist of durable cables that typically require replacement several times during the life of the medical equipment. Sometimes, these assemblies require performance upgrades. Alternatively, they may become damaged by age or repeated use.


Within the category of patient interface cables, there are several sub types.


Long-life patient interfaces include medical cable assemblies for ultrasound imaging and ECG diagnostic testing. These cables are durable, flexible and wear-resistant.


Limited-use interfaces include ICU and CCU monitor cables, as well as ECG diagnostic leads. These medical cables are damaged by repeated mechanical stress and exposure to cleaning chemicals, but are designed to last until scheduled replacement.


Use-only interfaces include catheters, electro-surgical devices, fetal monitoring cables, and neural simulator lead sets. They are sterilized and packaged in kits, and designed to be discarded instead of cleaned after use.


When selecting patient-interface products, buyers should consider the cost of replacement vs. cleaning these medical cable assemblies.


Connectors


The Engineering360 SpecSearch database contains information on several types of medical cable assembly connectors.




BNC connectors are secure bayonet-style locking connectors, commonly used with A/V equipment, professional test equipment, and older peripheral devices.




DIN connectors adhere to standards from Deutsches Institut für Normung, a German national standards body.




Digital visual interface (DVI) connectors cover the transmission of video between a source and a display. DVI connectors may transmit analog (DVI-A), digital (DVI-D), or analog/digital (DVI-I) data.




RJ-45 connectors are commonly used to transmit serial data.




Shielding


Cable assemblies may feature a type of electromagnetic shielding material, which is wrapped around the cable assembly underneath the outer jacket. Shielding serves to prevent electrical noise from affecting the transmitted signal, and to reduce electromagnetic radiation emission from the cable itself. Shielding is typically comprised of metal braiding, metal tape or foil braiding. A shielded cable assembly may also feature a special grounding wire known as a drain wire.


How Long Does It Take To Change A Engine Wiring Harness?


A technician may need to disassemble parts of the vehicle if they are attempting to access the wiring harness in question as it is difficult to reach. According to this example, installing a wiring harness can take no less than an hour or no more than 20 hours (i.e. if complications arise).
I often receive inquiries concerning InterConnect Wiring, like, “Can InterConnect fix or overhaul my wires?”. ” The short answer to that question is, “Yes! “. A new electrical wiring harness may be less costly than the one you’d need to replace an old one or replace it altogether.

How Do You Replace An Engine Wiring Harness?




Check the old and new connectors are the same.




Strip the ends of the wires, then pull out the wire clips to replace the wiring harness.




The wire ends should be twisted a little…




Insulated connections should be coiled to wire harnesses.




The Insulated Connector needs to be melted while the Wiring needs to be replaced.




Using an electrical tape, you can tape the wire to it.
