What Is a Smart Cable?

A cable is essentially a connector formed from wires twisted or otherwise bonded together to form an assembly. In electrical applications, cables are used to transmit power. A smart cable carries out this function while converting electrical signals.

Definition

• A smart cable is a cable that connects devices and contains an internal microprocessor. A microprocessor functions like a simple central processing unit, or CPU, contained on a single integrated circuit, or IC.

Protocol Conversion

• Protocols are sets of guidelines, or standards, used to facilitate the transfer of data, or digital information, across computer networks such as the Internet. Protocols often offer specific applications or functions. Converting protocols may allow a computer access to a specific application, program or even system. A smart cable converts digital signals it receives in order to modify protocols.

Universal Serial Bus

• Smart cables often use a Universal Serial Bus, or USB. USBs are a standard connection method for a wide array of computing devices, from PCs to PDAs. USBs are interface devices that can take the form of a power cord, and are used to connect peripherals or other devices to a host unit.
