What is SCSI, pronounced Skuzzy? No, it's not some sort of inappropriate language used to belittle a person. SCSI stands for Small Computer System Interface and this is a SCSI terminator that terminates the end of a SCSI chain. This cable is used with SCSI devices that have an Ultra Micro Centronics 68 (VHDCI) female port, like scanners and zip drives, to terminate the end of a SCSI chain. Belkin active terminators provide the clearest data signal maximizing signal integrity.
