How Can I Extend the Length of my Logitech Z623 Satellite Speaker Connection?

New “Ask the Cable Guy” Blog Question:

How do I Extend my Logitech Z623 Speaker System?

(Pictured: Rear Panel of a Logitech Z623 Satellite Speaker System)

Lou from Minnesota has approached us with an urgent question related to how to extend the connection on the back of his Logitech Z623 THX-Certified satellite speaker system. This topic comes up quite frequently because there is a lot of confusion out there about the connection type in question: d-subminiature or “d-sub” for short.

This question extends beyond any single particular brand or model. Many manufacturers will use this same High Density 15-pin d-sub interface (aka HD15 or DB15HD) in their own speaker and HTIB (Home Theater in a Box) designs. You can see the HD15 male connector in the picture above of the Logitech Z623, where it is labeled as “Right Speaker”.

(Left: Regular HD15 D-Sub) (Right: VGA HD15 D-Sub)

The speaker systems that use the HD15 d-sub interface tend to already come with some form of HD15 d-sub cable in the box, but what happens if you lose it or need to extend it in any way? A proper HD15 d-sub cable will solve that problem — but it has to be the correct choice for the application.

In the pictures above, can you really tell the difference between the regular HD15 d-sub on the left and the VGA HD15 d-sub on the right? They both have 15 pins. They both feature 3 rows of 5 pins each in a staggered arrangement. They both are contained within the same D-shaped housing. However, the similarities end there once you explore the insides of these cables.

(Pictured Above: Internal Pin Arrangement of Regular D-Sub)

First, let’s look at the regular HD15 Cables presently available at Cables on Demand. The drawing above for our Deluxe Series HD15 15-pin D-Sub Cable shows that the inside features 15 identically sized wires, all connected in a “straight-thru” pin-to-pin configuration (i.e. pin 1 routes directly to pin 1 on the opposite end of the cable). This simple arrangement is primarily designed for the transfer of low-speed data, i.e. RS232 serial port communications.

(Pictured Above: Internal Pin Arrangement of VGA Monitor D-Sub)

Next, let’s take a look at the VGA Monitor HD15 Cable presently offered by Cables on Demand. The drawing above for one of our Premium VGA HD15 D-Sub Cables is radically different from the regular HD15 cable shown previously. First, you will notice that a VGA HD15 Cable is not made of 15 identically-sized wires.

Instead, it consists of three different coaxial cables (used for RGB video signals), surrounded by several smaller wires. Also, while this cable type does feature “straight=thru” pin-to-pin wiring, it is not wired in order, i.e. the center pin of one of the coaxial cables goes to pin 1 and the shield return line goes to pin 6.

So now that we know the differences between the two HD15 D-Sub Cable types, which one is appropriate for extending a speaker system like the Logitech Z623 pictured above? The answer is the first cable profiled: the “regular” data-grade HD15 d-sub cable. While these regular d-sub cables are generally used for data transfer, one can think of audio as an analog form of data. A good rule of thumb: regular d-sub cables are generally beige or grey in color, whereas VGA d-sub cables are generally black in color.

The same wire used in our regular d-sub cable is also used in a variety of audio cables, such as speaker wire and instrument cables. As long as the d-sub cable is shielded, which all of our cables are, it can effectively transfer audio without the fear of noise entering the connection. The other HD15 d-sub cable type we profiled, the one designed for VGA video use, will simply not work because audio signals are not designed to transfer over coaxial cables!

Now that you know which cable type to get, head on over to www.CablesOnDemand.com today and search for part number CS-DSDHD15MF0. Alternately, you can simply click on the image above or link below to go directly to the product. Our 15-pin (HD15) Deluxe HD D-Sub Cable (Male/Female) can effectively extend your satellite speaker system by up to 25 feet — a vast improvement over the ~ 6 to 10-foot length cable included with the satellite speaker system!

For cases where the speaker system is installed in an environment more prone to interference, or in cases where you need to extend the speaker system by up to 50 feet, we highly recommend taking a look at our 15-pin (HD15) Premium HD D-Sub Cable (Male/Female) (pictured above). Our Premium HD15 D-Sub Cable (part number: CS-DSPMHD15MF) features double shielding (Aluminum Foil + Aluminum Braid), helping to preserve the audio signal over a longer distance. For extensions of 25 feet or less, our Deluxe D-Sub Cable with its Copper Foil Shielding will work just fine.

USB Cable Guide from www.CablesOnDemand.com

Introduction

Our exclusive USB User Guide is designed to address all of your questions regarding USB technology. Whether you’re looking for a basic technical primer on the subject, or require more specific information on which USB cable is right for your application, Amphenol CablesonDemand.com has you covered. With thousands of USB cables available in stock everyday, we’re ready to address your USB needs, large or small.

Despite its widespread popularity today, the USB (Universal Serial Bus) interface faced a tumultuous upstart back in 1996. Many of the first generation USB devices failed to follow the guidelines provided in the USB specification, causing headaches for users. Most of the problems found with early USB devices were tracked down to software incompatibilities. The Windows 95 operating system never properly integrated USB technology, despite several attempts to do so. This all changed in June of 1998 with the release of the Windows 98 OS, which was designed to support USB from its inception. In the six years following the release of Windows 98, over 1 Billion USB devices went online worldwide.

Why USB?

USB is the defacto industry standard computer interface because of its immense benefits over prior technologies. These benefits include:


• Speed – USB supports high speed datatransfer between today’s devices • Expansion – A single USB port can support up to 127 different devices • Ease – USB features “Hot Swapping” and “Plug and Play” capabilities
	The USB “Trident”Logo

Speed

The development of the Universal Serial Bus was an absolute necessity. The proliferation of the internet, MP3 players, PC peripherals, PDA’s, and other mobile devices increased the demand on a computer’s ports. For over 15 years, computers relied on serial and parallel ports for their connection to the outside world. These bulky interfaces relied on a standard known as RS-232 to transfer data.

While RS-232 could handle basic I/O functionality for simple devices like mice and joysticks, it was never intended to handle the high speed data rates demanded by today’s devices. The maximum transfer speed for a serial port is roughly 115,000 bps (bits per second). The maximum transfer speed for a parallel port is roughly 2 Mbps (megabits per second). USB, by comparison, supports data transfer rates up to 480 Mbps; over 4,000 times faster than a serial interface. It is no wonder why nearly all notebook and desktop PC’s sold today fail to include serial and parallel ports in their designs.

9-Pin Serial Port 25-Pin Parallel Port

Expansion

Before the advent of USB, expanding ports on a PC was a daunting task. Most PC’s came equipped with at most two serial ports and one parallel port. If you needed to connect anything beyond a mouse and a printer, it would require opening up the computer and installing an expansion card. USB was designed to eliminate these expansion problems from the onset by supporting up to 127 different devices on a single port. Since an average PC comes equipped with four USB ports, one could potentially support over 500 devices from a single machine.

Now, 500 devices hooked up to a single computer is a bit of exaggeration, but it is theoretically possible. What if you need more USB ports than are presently available on your PC? A USB Hub is a cheap and effective device that connects to a single port and splits off into four or more new ports. They’re available in two varieties: powered and unpowered. Larger devices like printers or scanners usually come with their own power supply. Smaller devices such as webcams, joysticks, mice, and thumb drives are powered by the computer’s USB port directly. Each port has a power limit, so a powered USB hub may be necessary if your devices are power hungry.
		USB Hub

Ease

USB was designed with ease in mind. Gone are the days of wasting hours on end trying to manually load software drivers to a new device up and running. USB devices are a breeze to set up thanks to Plug-and-Play technology. Plug-and-Play is a computer feature that allows the addition of a new device, normally a peripheral, without requiring reconfiguration or manual installation of software drivers. The computer will either install that new device automatically or will simply prompt you for the CD included with that device. Although early implimentations of Plug-and-Play for USB (then known as Plug-and Pray) were troublesome, the process has mostly worked itself out.


	USB Fan USB Heated Gloves

ttUSB is also an easy technology to work with from an Orignal Equipment Manufacturer’s point of view. USB connectors are extremely reliable and inexpensive. Since USB is an internationally adopted technology, specialized software is not required for its implementation. OEM’s have come up with some pretty interesting USB devices over the years based on the fact that it is easy to tap into the USB port’s power supply. USB lights, USB fans, USB air darts, even USB heated gloves are on the market.

USB Cable Overview

USB cables are designated by the connector types used on each end. The Type A connector is flat and always goes to the computer whereas the Type B connector is more square-like and always goes to the device. Most USB cables use male connectors, with the exception of a USB extension cable, which features a female Type A connector on one end.

USB Type A USB Type B

ttNeed help in finding the right USB cable for your particular device? Although some manufacturers elect to use a special proprietary USB cable that is only compatible with their device, most tend to use one of several standard cables. CablesonDemand.com has all of these standard cables in-stock and ready to ship. A quick overview of these standard cable varieties is provided below.

USB Type A-B Cable

The USB Type A-B cable is primarily used to connect a peripheral device to the PC. This is the most common USB cable on the market today. Nearly all printers, scanners, and external drives utilize the USB Type A-B cable. It should be noted that most new printers fail to include a USB cable in the package.

USB Type A-A Transfer USB Type A-A Extensiontt

ttThere are two styles of Type A-A USB cables on the market today. The Type A-A Male to Male cable is used primarily to transfer data between two PC’s. They are commonly known as USB transfer cables and are often bundled with special computer back-up software. The type A-A Male to Female cable is used to extend the length of an existing USB cables. USB cables can be extended by up to 10 feet without the need for a booster. To view our selection of USB Type A-A cables, please click here.

USB Type A-Mini B (4-Pin) USB Type A-Mini B (5-Pin)

ttWith the widespread proliferation of cell phones, PDA’s, digital cameras, and MP3 players, it was necessary to create a low profile USB interface. The USB Type A-Mini B cable was the solution offered by the latest USB 2.0 specification. These cables can interface with a PC and support the maximum USB transfer speed just like a standard USB cable, despite the reduced size. The first USB Type A-Mini B cables offered on the market featured a 4-pin connector on one end whereas most modern cables feature a 5-pin connector on one end. There are some subtle differences between the two. To browse our selection of USB Type A-Mini-B cables, please click here.

ttThe 4-Pin Mini-B USB interface was introduced in 1999 with a nearly square connector that is essentially a scaled down version of the standard type B. These connectors are mostly found on early generation digital cameras and MP3 players. Sony uses a special version of the 4-pin for many of their cameras. Most of the USB compatible portable devices built before the year 2003 feature the 4-pin Mini-B as their interface of choice. To go straight to our selection of 4-pin Mini-B cables, please click here.

ttThe 5-pin Mini-B USB interface is the most common type found on today’s popular portable devices. Essentially most of the digital cameras, cellular phones, MP3 players, and PDA’s sold since 2003 use this interface. The inclusion of an additional pin was established to support a new USB feature called USB-on-the-go. This allows the device itself to initiate the USB link rather than the computer, making installation a snap. To go straight to our selection of 5-pin Mini-B cables, please click here.

tttt

Special Tip

To properly identify the type of cable needed for your device, simply take a look at some of the features of the connector. The 4-pin connector is square shaped whereas the 5-pin connector is more rectangular. In the picture above, you can clearly distinguish 5 gold colored dots in the center of the connector. These are the “pins” of the connector, and therefore the 5-pin Mini-B cable is the proper choice. Please feel free to compare the interface on your device to the diagrams above for reference purposes.

Guide to HDTV Cables from www.CablesOnDemand.com

HDTV Cable Technology Overview

Unfortunately one of the most critical factors in ensuring a stellar HDTV experience is often overlooked. Simply using an incorrect cable for your HDTV installation can lead to an 80% reduction in picture quality, even if you’ve invested in the proper equipment. Some of the most common video cables used by today’s A/V devices simply cannot handle the strict technical requirements imposed by HDTV.

Common A/V Cable Types

Coaxial / RF Composite Video S-Video

HDTV Support: NO HDTV Support: NO HDTV Support: NO

If you are using any of the cables shown above as the connection between your HDTV and HD source equipment, you are missing out on the HDTV experience. This is one of the best indicators of HDTV compatibility, since a quick glance at the back of your equipment can verify whether the installation is compliant. These cables can still be used for connections between legacy equipment like VCR’s and an HD display.

Common HDTV Cable Types

Component Video DVI HDMI

HDTV Support: YES HDTV Support: YES HDTV Support: YES

A great majority of HDTV’s can utilize any of the three cable types shown above. Component Video, DVI, and HDMI cables are all fully compatible with HDTV signals. All of these cables are optimized specifically for the purpose of carrying high resolution video signals such as HDTV. CablesonDemand.com carries all of these HDTV cable options for your home theater.

Component Video

Component Video is the oldest cable technology commonly used for HDTV’s. Component Video cables support an analog system of signal transmission. Component Video is very similar to the VGA/SVGA system used primarily on computer displays. Component cables can always be identified by their distinctive red, green, and blue markings. The image quality provided through a Component Video

quality provided through a Component Video connection is quite impressive, but not quite as sharp as a digital connection like DVI and HDMI. DVD players almost always provide the best picture quality through the Component Video connections.

Since Component Video is an analog technology, it can be prone to interference, especially over extended runs. Component Video cables from CablesonDemand.com are designed to combat these problems. Gold Plated RCA connector terminations eliminate signal drop-outs caused by corrosion. Low-loss double shielded RG-59 coaxial cable permits longer cable runs and protects against interference.

Compatible with all devices featuring Component Video connections; including HDTV’s, DVD Players, Sony PS3™, and X-Box 360™ game consoles.

To browse our selection of Component Video cable products, please click the image on the right.

DVI Video

DVI, or Digital Visual Interface, was the first all digital video connection technology used for HDTV’s. Although originally developed for flat panel computer displays, the technology quickly migrated to the HDTV market. HDTV’s specifically use the DVI-D connection type designed to accommodate digital video signals. Due to its digital nature, a DVI connection produces a stunningly detailed image. DVI should be considered first over Component Video if the

option is available. Although most late generation HDTV’s use HDMI connections, it is possible to convert between HDMI and DVI using the proper cable.

DVI cables from CablesonDemand.com feature a mixture of copper twisted pair and coaxial cable conductors in a flexible jacket. An additional layer of shielding is included to isolate the DVI cable from potentially harmful interference. Conductors are precisely spaced to maintain signal integrity over extended runs.

Compatible with all devices featuring DVI-D or HDMI (with converter cable) connections; including HDTV’s, Digital Computer Displays, Upscaling DVD Players, HD-DVD™ and BlueRay™ Players, Sony PS3™, and X-Box 360™ game consoles.

To browse our selection of DVI cable products, please click the image on the right.

HDMI Video

HDMI, or High Definition Multimedia Interface, is the premier HDTV interface. Specifically designed for High Definition devices, HDMI provides both uncompressed high resolution digital video and multi-channel surround sound over a single link. This drastically reduces your cabling requirements and setup time. The video component of the HDMI interface is backwards compatible with DVI when using the proper cable. HDMI should always be the preferred connection method if your equipment supports it. HDMI is a scalable technology, thus allowing for future technology upgrades without the need to replace the cable.

HDMI cables from CablesonDemand.com have been certified by an HDMI compliant test lab. This compliance testing ensures that the cable uses the proper wire gauge and layout per the HDMI specification. By following such tight tolerances in the construction of the cable, HD resolutions up to 1080P are supported.

Compatible with all devices featuring DVI-D (with converter cable) or HDMI connections; including HDTV’s, Digital Computer Displays, Upscaling DVD Players, HD-DVD™ and BlueRay™ Players, Sony PS3™, and X-Box 360™ game consoles.

Questions About 10GbE CX4 Cables? Check Out the CX4 Cable FAQ!

Leave a reply

10GbE-CX4 Cable Frequently Asked Questions

Network Engineers have a plethora of cabling options when it comes to installing a 10-Gigabit Ethernet compliant backbone, but which solution is truly optimal under the circumstances? 10-Gigabit Ethernet CX4, aka 10GbE-CX4 or 10GBASE-CX4, combines low cost, low latency, and low power consumption for the ultimate short-distance link. Although CX4’s popularity has grown rapidly in recent years, there is still a great deal of confusion and misinformation regarding this technology. Our exclusive Guide to CX4 Cables will help with all of your CX4 related questions.

Question 1: What is CX4?

CX4, also known by its IEEE designation, 802.3ak, supports 10-Gigabit Ethernet data transfer over 4-lanes of copper cabling in each direction (8-lanes total). In order to rapidly bring this technology to market, the IEEE workgroup designed CX4 to utilize field-proven InfiniBand type cabling and connectors. Nearly one quarter of the world’s Top 500 super computers utilize InfiniBand interconnects for mission-critical applications, making it an ideal choice for CX4 use. While InfiniBand is more proprietary in nature and requires licensing fees, CX4 is based on an Open Source MSA (Multi-Source-Agreement), allowing any manufacturer to develop CX4 products at significantly lower costs.

Question 2: What is CX4 Used For?

CX4 is primarily used as a 10-Gigabit Ethernet interconnect for backbone applications. With the rapid rise of Gigabit Ethernet at the desktop level (1000BASE-T), a broader data pipeline is required on the back-end to aggregate data between servers. Therefore, it is not uncommon to see CX4 capable switches installed in nearly any environment, including data centers, enterprise networks, or even HD video distribution hubs.

Question 3: Are there any Limitations to CX4?

CX4 interconnects offer the advantages of low-cost, low-latency, and low-power consumption at the expense of range. The length limitation for CX4 is 15m (49ft) when using passive cable assemblies. Some novel solutions exist which use active signal boosters or fiber optics to achieve lengths beyond 15m, but these solutions negate the cost, latency, and power benefits inherent to CX4 technology. Fortunately, lengths beyond 15m are rarely needed, since most switches reside in close proximity within a wiring closet.

Question 4: What do I Need to Integrate CX4 into my Network?

Depending upon your particular requirements, several upgrade paths exist to integrate CX4 into your network. Many switches from companies such as HP, Cisco, and Intel can be upgraded with a CX4 plug-in module. These CX4 modules are available in XENPAK, X2, and XFP configurations. Another option is to purchase a new CX4 capable switch. These high performance switches often feature a combination of CX4 ports and standard RJ45 ports for Gigabit Ethernet. Nearly all servers with PCI-Express slots can be upgraded with a CX4 enabled PCI-E NIC card. Finally, you will need quality CX4 Cables to connect to your gear.

Question 5: What Types of Connectors are used on CX4 Cables?

A properly designed CX4 cable should feature die-cast SFF-8470 InfiniBand type latching connectors. These connectors are easy to engage and will maintain continuity even if significant strain or vibration exists along the body of the cable. SFF-8470 thumbscrew style (i.e. SAS) connectors should be avoided since most equipment does not support them. Amphenol CX4 cables utilize the best connector on the market today, the Fujitsu microGiGaCN™. The microGiGaCN is the market’s original high-speed, differential-signal, copper interconnect for high-performance (data I/O) applications.

Question 6: How Does CX4 Compare with 10GBase-R & 10GBase-T?

CX4 has numerous advantages over 10GBase-R (Fiber) and 10GBase-T (Cat-6). An optical connection would require (2) 10-Gig optical modules and a fiber patch cord to function. This has significant cost and power budget implications. Running 10-Gigabit Ethernet over UTP cabling like Cat-6 may sound promising, but it is plagued by power consumption and latency issues. Today’s 10GBase-T chipsets are power hogs, as they require several Watts just to separate out signal noise. Here’s a comparison of how CX4 stacks up in terms of power-consumption in a 50-server datacenter. Essentially, CX4 consumes 6x-20x less power.

Power Comparison Chart

Question 7: What is SpectraStrip SKEWCLEAR Cable?

SKEWCLEAR® is a proprietary shielded parallel pair wire technology designed and built by Amphenol SpectraStrip. When transferring high-speed data over copper, signals will often arrive out of sync. This problem, known as skew, can lead to the complete collapse of signal integrity. SKEWCLEAR®,cable utilizes a novel manufacturing approach directed towards reducing within-pair and pair-to-pair time delay/amplitude-skew, critical for today’s high bandwidth applications. All Amphenol CX4 cables feature SKEWCLEAR® wire.
