What are SCSI connectors?
SCSI, or Small Computer Systems Interface, is technology designed to connect smaller devices to a computer. SCSI is bus technology, which means that all devices connect to a central bus and are "daisy-chained" together. The SCSI bus is controlled by a host controller which will typically be built into the motherboard, or it can be from a separate expansion card. Either external or internal, the cabling/connector requirements for an SCSI connector depend upon the location of the bus. SCSI uses three different signaling types, Single-Ended (SE), Differential (HVD or high-voltage differential), and LVD (or low-voltage differential). The most important things to remember when selecting your SCSI cable is the type of connector required by your devices, and if the location of the cable is internal or external.
