Abstract
A system and method for transferring data with a peripheral of a computer controlled system is presented. The system and method comprises a means for monitoring an interface cable between the peripheral and the peripheral controller to identify an idle interval, a switching means for connecting a controller to the interface cable for transferring data between the controller and the peripheral, and a communications port for transferring commands and data between the controller and an another computer. The system and method transfers data with the peripheral without consuming memory or CPU resources of the computer controlled system.
Claims22
A system for accessing data of a computer controlled system, comprising:
- a means for monitoring an interface cable between a peripheral and a peripheral controller of the computer controlled system to identify an idle interval;
- a switching means for electrically connecting a controller to said interface cable to transfer a data between said controller and said peripheral during said idle interval without consuming memory or CPU resources of the computer controlled system;
- and
- a communications port for receiving commands from a second computer and transferring said data with said controller.
A system for controlling a legacy computer controlled system, comprising:
- a first crimping portion of a coupler for electrically connecting to a peripheral data cable of the legacy computer controlled system by displacing an insulating layer surrounding a wire of said peripheral data cable and contacting said wire;
- a second crimping portion of a coupler for securing said first crimping portion to said peripheral data cable;
- and
- a second peripheral data cable in electrical communication with said wire, said second peripheral data cable transmitting a data to a peripheral hard drive of the legacy computer system via said wire during an interval when said legacy computer controlled system is not accessing said peripheral hard drive, said data altering a functional operation of the legacy computer controlled system.
A method of controlling a computer comprising:
- monitoring a data communications cable of the computer;
- identifying an idle interval when the computer is not communicating with a hard drive using said data communications cable;
- and
- switching a controller onto said data communications cable;
- transmitting a data between said controller and said hard drive using said data communications cable, without consuming a memory resource or a cpu resource of the computer.
A device for interfacing with hard drives, comprising:
- a target hard drive;
- an interface cable;
- and
- a target interface card.
