Serial cable assemblies are used for the serial transmission of data. Serial type, cable construction, features, and applications are important specifications to consider. Choices for serial type include: RS232, RS422, RS485, Fibre Channel, IEEE 1394, USB 1.1, and USB 2.0. RS232, RS422, and RS485 are serial standards approved by the Electronic Industries Association (EIA). RS232 uses a serial binary data interchange to interface data terminal equipment (DTE) to data communications equipment (DCE). RS422 and RS485 are balanced serial interfaces for the transmission of digital data. They provide greater immunity to noise and are designed for greater distances and higher Baud rates. RS485 can also be transformed into a multi-point application. Serial cable assemblies that use Fibre Channel incorporate links of twisted-pair, coaxial, or fiber optic cable. Small computer system interface (SCSI) devices can use fibre channel arbitrated loop (FC-AL), the most popular Fibre Channel typology. IEEE 1394 or FireWire^® (Apple Computer, Inc.) is a serial interface standard adopted by the Institute of Electrical and Electronics Engineers (IEEE) for very fast digital data transfers such as streaming video. There are two universal serial bus (USB) standards for serial cable assemblies. The original standard, USB 1.1, supports data transfer rates of up to 12 Mbps. USB 2.0 is faster than USB 1.1 and supports data transfer rates of up to 480 Mbps.
