A differential SCSI/single-ended SCSI interface adapter/converter

摘要

An interface match converter between a differential SCSI bus and a single-ended SCSI bus, wherein a plurality of differential receivers and transmitters are selectively controlled by a state machine (23) capable of recognizing the participation in an arbitration step of at least one unit (25) connected to a single-ended bus, the unit (25) as being successful in the arbitration and selection/re-selection of another unit connected in the differential bus, or a request for selection/re-selection from a unit connected in the differential bus being addressed to a unit (25) connected in the single-ended bus, and accordingly, of suitably controlling the flow of information being transferred between the two buses. <IMAGE>
