Abstract
A state machine is used to remove residual electric charge from a sense line and to sample the voltage of the sense line at multiple pre-determined times to determine the presence of a terminating capacitor and its value. Various values of capacitors identify discrete conditions. These discrete conditions may identify different types of plug-in cards or models of plug-in cards within a group type.
