They are available with or without locking options and robot flexibility and are fully compatible with our range of cameras and interface cards. For a more in-depth discussion of the different connector types, please refer to the cabling section. At the time of writing we started to see a few camera products being announced using Thunderbolt, Light Peak and PCIe interfaces. All of these interfaces provide the option for one of the existing camera standards to sit on top.
These standards effectively extend the internal PC, but to a copper or fiber wired connection, allowing along frame grabbers to become external to the PC, or a ultra high-speed camera to connect directly to the PC. The first generation of cameras that required a digital output in the 's and 90's used parallel digital; firstly RS and later LVDS. There are still some cameras that use this technology, but as there is no standard, every combination of camera and frame grabber uses a different connector, which makes cabling very complex. Because the speed of the interface is limited, many cameras use multiple channels or taps to increase data throughput and many of these digital cameras offer high dynamic range output that requires 10, 12, 14 or even 16 bits per pixel.
LVDS and RS require two wires per signal, therefore, for a bit camera with two output taps the required cable contains about 70 wires, including timing and control. Parallel digital interfacing has largely been replaced by CameraLink. The simplest form of analogue interface uses a single 75 ohm coaxial cable that transmits the video and timing information using the same signal.
What does IEEE 1394, Firewire and iLink mean?
Trying to fit all this information down one wire naturally limits the image quality, and so for colour applications, the colour or chrominance information is often transmitted over a separate cable from the luminance monochrome signal. This system is known as the S-Video standard. To maintain the best possible colour image quality using analogue technology, each colour signal uses a separate channel, requiring 3 cables: one each for Red, Green and Blue. This interface is called RGB. Within the vision industry there is also an additional requirement to support dynamic exposure control and asynchronous triggering.
To achieve these, the timing signals are usually separated from the video signal and this additional exposure control requires two or three extra cables.
Although there are no official standards, the Hirose connector has become the de-facto standard for analogue vision cameras, making interfacing relatively easy. In the digital era analogue cameras are generally not specified in new applications and with Sony's announcement of the closing of their CCD factory we expect this standard to die by at the latest. FireWire is Apple Inc. Apple's development of the original IEEE was completed in The aim of current work is to incorporate all four of these documents into new revision of the standard.
What Is FireWire?
Sony 's version of the system is known as i. LINK, and uses only the four signal pins, omitting the two pins which provide power to the device because of a separate power connector on Sony 's i. LINK products. The 6-pin connector is commonly found on desktop computers, and can supply the connected device with power.
Typically a device can pull about 7 to 8 watts from the port; However, the voltage varies significantly from different devices. Modification IEEE a was released in It standardized the 4 pin connector already widely in use. The 4-pin version is used on many consumer devices such as camcorders, some laptops and other small FireWire devices. It is fully data compatible with 6-pin interfaces.
What does IEEE , Firewire and iLink mean?
This newer specification b and corresponding products allow a transfer rate of It is backwards compatibility to the slower rates and 6-pin connectors of FireWire However, while the IEEE a and IEEE b standards are compatible, connectors are different, making the cables used by previous versions incompatible. In December , the Trade Association announced the products will soon be available using S mode.

It will use the same 9-pin connectors as the existing FireWire and will be fully compatible with existing S and S devices. The future products are intended to compete with the USB 3.
The first version can transfer The versions that came afterwards can do this speed, and multiples of it. Using the SI prefix, this is exactly To avoid confusion, it is rounded to the next closest That way, S does not transfer 3. Unlike with USB, there is no one device that manages the bus all the time.

Each device is able to manage the bus. When a new device is connected, there will be negotiations between the devices which of them does the management. Addresses have a length of 64 Bits.
Of these, 10 are used to identify segments as part of the network , 6 are used for nodes, and 48 are freely available. The standard used to connect several segments has not yet been ratified. For this reason, all Firewire networks currently only use one segment. Devices on a FireWire bus can communicate by direct memory access.
