Abstract
A system and method for automatically enabling and disabling a termination impedance circuit for a computer bus. A peripheral device on the computer bus has two external bus connectors. A connector cover is provided for at least one of the peripheral bus connectors. The connector cover must be removed before a mating bus cable connector can be attached. The presence or absence of the connector cover is detected by sensor within the peripheral device. If a connector cover is detected, one of the peripheral bus connectors must be open (not connected to the bus) and termination is enabled. If a connector cover is not detected, termination is disabled. In one embodiment, the connector cover has a projection that passes into the peripheral device. In an alternative embodiment, a reflective surface is used. The cover may optionally be captured by a hinged edge or attached via a tether.
