Abstract
A cable for connecting a peripheral device to an input/output port configured in accordance with either a SCSI protocol or a parallel port protocol has a first connector which has a plurality of contact pins for connecting the cable to the peripheral device; a second connector which has a plurality of contact pins for connecting the cable to the input/output port; and a plurality of twisted pairs each having a first conductor and a second conductor. The first conductor of each of the twisted pairs is a data/control line, and the second conductor of the twisted pair is a return for the respective data/control line in accordance with the SCSI protocol. The first and second conductors of each of the twisted pairs are connected between selected pins of the first and second connectors such that none of the twisted pairs carries a data/control signal on both its first and second conductors when the cable is connected to an input/output port that is configured in accordance with the parallel port protocol.
