Abstract
A cable used for transmitting the signals of a communications bus, such as a SCSI bus, having arbitration control signals subject to a wired-or glitch--such as the SCSI BSY signal. Low characteristic impedence conductors ensure that voltage reflections resulting from the deassertion of the BSY signal do not exceed a minimum threshold signal assertion voltage, allowing an increase in the maximum length of the SCSI bus cable.
