Abstract
A bus system providing increased connection flexibility and hot pluggable connections includes an open collector bus, a receiver connected to the open collector bus via a current sensor, a driver connected to the open collector bus, a peripheral card and a flexible cable operatively coupling the peripheral card, the receiver and the driver so as to provide point-to-point connection between the peripheral card and the open collector bus. The current sensor provides a control signal to the driver to increase the impedance of the driver in the event that a current is produced by the peripheral card.
