WHITE PAPERS FROM THE 1394 TRADE ASSOCIATIONUsing Apple's Target Disk Mode with FireWire (IEEE1394) Apple has provided a useful feature on their FireWire equipped computers, since May of 1999 with OS 8.6, called Target Disk Mode (TDM). This allows users to make their Macintosh internal hard drive appear as an external FireWire hard drive to another FireWire-enabled Mac. There are many uses for this beyond copying files between machines. This article outlines this and a number of other uses of TDM. In particular, system backup and restore, disk troubleshooting and repair are explained. Additionally, TDM will present any optical drives, to another Macintosh, which can be useful for MacBook Air owners or for Mac's that have older optical drives that, for example, do not support dual-layer DVD's. It's also a time-saving feature for those who want to upgrade to a larger hard drive, or to migrate files and settings to a new Mac. Most, if not all, of the tools you will need for all of this are included in OS X. Digital Audio Relies on the Features and Benefits of IEEE 1394, by Morten Lave, CEO of TC Applied Technologies Like most everything else, professional audio production happens almost entirely in the digital domain these days. The digital transition has enabled amazing production capabilities on PCs using digital audio workstation (DAW) software. But with the digital transition came the need for a digital interconnect that had the bandwidth needed to move audio streams in real time along with the need for timing and synchronization capabilities that allow mixing of multiple audio channels. The 1394 or FireWire interconnect has proven to be the only interconnect that can support pro audio applications. 1394 Maximizes Value in Security Camera Networks, by Dimitrios Staikos, Codemost Technology Ltd. Inc. Companies making security and surveillance Systems that rely on multiple cameras are facing a major technology transition – the swap to an all-digital system. That transition will necessitate a digital network that links all of the cameras in an installation. Video-centric security systems in the past have typically used analog connections that link remote cameras to a surveillance control center. Older systems have even stored video on analog media such as videotapes. More modern analog designs digitize the video using servers in the control center. Industry-standard compression techniques yield video that is stored on disk drives for quick access and the ability to jump instantaneously to any timestamp in a recorded stream. Avoiding Design Errors in 1394-Based External Storage Systems Dave Thompson, LSI and Don Harwood, PLX Technology IEEE 1394, also known as FireWire, has become a standard of choice for storage applications. FireWire is a popular and proven standard, and while it is familiar to many system designers, there is still the potential to make design errors that can compromise performance. IEEE 1394 Ideal for Long-Haul Automotive, Consumer, Industrial, Security and PC Applications How to Use FireWire for Innovative New Designs without Distance Constraints Les Baxter, Baxter Enterprises Since 1995, FireWire has been a proven and popular interface for short haul audio and video transfer in PCs, storage products and consumer electronics. To date over 1 billion ports have shipped. Now the 1394b version of FireWire (known as Beta mode), which runs at up to 3200 Megabits/second, is becoming an interface of choice for innovative and advanced long haul applications. Since the publication of the 1394 Copper Automotive Specification in 2008, there has been significant interest in FireWire for automotive applications as well. Proven 1394 Technology Trumps Ethernet AVB Potential With the automobile becoming yet another home for a network of interconnected intelligent subsystems, vehicle designers must choose a multimedia network technology. Modern automobiles need a way to move everything from video to safety data around the auto. Ethernet works well in the office and the home, and at first glance it might appear a good fit for vehicles. A detailed investigation, however, reveals that the Ethernet physical layer (PHY) is not a proper match for the automotive environment, and that no high-level protocols exist for multimedia delivered over Ethernet in the automobile. Conversely, 1394 has a more flexible PHY that supports numerous topologies (including preferred daisy-chained connections) and also includes proven protocols for passing real-time multimedia streams. Reference Tables for FireWire Isochronous Bandwidth Usage Correctly calculating the bandwidth required in a FireWire application that uses isochronous streaming is crucial to the success of the application. Although the calculations are fundamentally simple, they involve some rudimentary math, which can always go wrong and require some solid understanding of how FireWire works. Too often these calculations are not done correctly and, as a result, FireWire either is underutilized or overutilized to the point where the application might start to experience significant problems, usually of intermittent nature. With higher FireWire speeds of 1.6Gbps and 3.2Gbps now coming to the market it is important to ensure that designers and implementers understand the technology and use the available tools to maximize FireWire’s performance -- without risk to their solution. The details in this paper provide a concise explanation of how FireWire bandwidth works, and a complete set of reference tables so users can achieve these objectives. Tables are provided for users who intend to oversubscribe the available isochronous bandwidth to a certain extent, so that in these cases the designer can make the correct calculations. FireWire Reference Tutorial (English | Chinese - Traditional | Chinese - Simplified) This document is a FireWire tutorial aimed at engineers that have no previous exposure or understanding of FireWire. Its purpose is to familiarize the reader with FireWire and to build a sound and complete understanding of how the FireWire bus operates from the experiences of expert members of the 1394 Trade Association. This document provides guidelines for implementing FireWire (IEEE 1394) ports on both high level complex devices such as personal computers and simple devices such as inexpensive consumer electronics products. The guide includes references to normative specifications as well as full reference designs that can be used as is or, with the careful consideration of the trade-offs, as a starting point for a more optimized design. 1394 Automotive Camera Systems Are on the Move: Simple Designs with High Bandwidth, Low Latency and Scalability, by Richard Mourn Automotive camera systems are progressing from a single backup camera and simple sensors to detect objects to smart driver assist systems such as collision avoidance and sign recognition. These systems require high bandwidth, low latency, multi-camera synchronization, and scalability; and they must meet general automotive considerations like low cost, low maintenance and reduced weight, achievable using a flexible wire harness. Of Windmills and Recording Studios, by Burke Henehan Windmills are pleasing to the eye, but the size, violence, and expense of these mega-machines make them even more impressive. They are standalone power plants, 40 to 80 meters above the ground, costing more than a $1 million USD each with 20+ year life spans, meaning they require maintenance. This article describes the need for a machine monitoring system in wind turbines, how the requirements for a music studio network are similar to a wind turbine’s machine monitoring system, and how a FireWireTM music studio networking system has been used to create a condition based maintenance system for wind turbines. FireWire Security Imaging, by Burke Henehan FireWire™ is not merely the fastest network for connecting your external hard drive and other peripherals – it is also the most environmentally friendly. Using Power over FireWire, you can not only reduce your energy usage, you can eliminate the cost and toxic waste that comes from the production and disposal of millions of external power supplies or “wall warts."

Read More Home Entertainment Networks and Flying Cars Today’s entertainment networks are reminiscent of the flying cars we have been promised for years but only see in magazines or demonstrations. They are typically cobbled together from parts that require professionals to assemble and maintain, are expensive, and both have a tendency to crash when operated by someone with inadequate training. This white paper provides an in-depth look at the new 1394 specification that addresses these issues with a sophisticated, cost-effective, and secure solution. IEEE1394: versatility, performance, security, flexibility The advent of digital representations of all media types has fundamentally changed the way consumers use electronic products and blurred the distinction between computers and consumer electronics. Today, consumers demand products that interoperate whether a device lives in the office or the living room. Interoperability mandates a versatile interconnect. Too often, consumers must rely on multiple links – a situation that’s inconvenient, often offers sub-par performance, and hampers the user experience. IEEE 1394 (also known as FireWire™ (and the terms are used interchangeably throughout this document) remains the single best interconnect across the range of computer, data storage, consumer electronic, and service-provider supplied products in terms of performance and versatility. This paper provides a complete review of these features, including the results of recent benchmark tests and a heads-up about the future of 1394 and related products. Simply POF: High-End Connectivity with Plastic Optical Fiber Plastic Optic Fiber, or POF as it is widely known, offers affordable, high-end connectivity for office and home networks. With speeds of 250 Mbps (and Gigabit just around the corner), POF is a superior alternative to copper used in traditional networks. The 1394b high performance serial bus offers outstanding features to meet the demands of a multiple purpose network. Simply POF provides a complete review of these features and their implementation.
