Abstract
A method and implementing system is provided which includes a switching device as part of a circuit board transmission line or trace serially connecting a plurality of device terminal sockets to a common node. When device terminals are left unconnected, corresponding segments of the connecting transmission line on the circuit board are disconnected to provide transmission line segments corresponding to the number of devices actually used. As a result, signal transition time for signals at the common node is optimized in accordance with the number of devices actually used.
