An improved electrical connector for connecting bus lines to a card such as a memory card or media card, including a multi-level connector comprising a latching device having a plurality of insertable latch positions that advantageously allows for selectively connecting or isolating an electrical path to an adjoining connector. The connectors of unpopulated DIMM slots are disconnected from the network along with the traces that would normally form a stub with associated undesirable signal reflections that would otherwise disturb the signal transmitted to the receiving end if not properly terminated. The contacts of the edge connector itself are used as a means to selectively connect or disconnect adjacent/downstream cards in a serially cascaded architecture. The burden of the stubs due to unpopulated card slots and the need to place one card at the far end of the network are thus eliminated.
