In terms of workstations, IEEE1394 is a very common interface. The predecessor of IEEE 1394 was drafted by Apple in 1986. Apple called it FireWire, Sony called it i.Link, and Texa Instruments calls it Lynx, but in fact all the brand names refer to the same technology - IEEE 1394.
IEEE 1394 is a high-speed serial bus designed to enhance the connection performance of external multimedia devices and computers. The transmission rate can reach 400Mbps. Using IEE1394 technology, we can easily connect computers and cameras, high-speed hard disks, and audio equipment Wait for the data stored in the device to be poured into the PC. It has two data transmission modes - synchronous (Isochonous) transmission and asynchronous (Asynchronous) transmission. The synchronous transmission mode will ensure the bandwidth of a certain connection. This is very important for real-time images, because audio and video data will have its own time limit, and excessive delays cannot be accepted.
IEEE 1394 supports hot swapping, which can automatically detect the addition and removal of devices and reintegrate the system without manual intervention. The cable used by IEEE 1394 includes six copper wires, two of which are used to power the device, providing a voltage of 8-30 volts and a maximum power supply of 1.5 amps, and the other four are used for data signal transmission.
Generally speaking, IEEE-1394 has the following characteristics:
Cheap - Small footprint - Fast - Open standard - Hot-swappable - Scalable data transfer rate - The topology is flexible and diverse - fully digitally compatible - peer-to-peer networks can be established - both synchronous and asynchronous data transmission modes are supported.
