This concept is similar the USB-powered devices to receive power from a power source such
as a Repeater or Frame Grabber. PoCL has an advantage of reducing the number of interfaces
required by the back of the camera. That is, using the four drain of the Camera Link cable wires
(4 ground), the power cable can be removed from the camera. Not only it does not have any
effect the quality of data from the camera, but also it is very helpful in reducing the cost and size
of the system to remove the power source terminal.
