CABLE ASSEMBLIES - SCSI TYPES
SCSI-1
The original SCSI standard was approved in 1986. It supports transfer rates of up to 5 Mbps and 7 SCSI devices on an 8-bit bus. The most common connector for SCSI-1 is the Centronics 50 or Telco 50. A micro ribbon 60 connector may also be used.
SCSI-2
Approved in 1994. SCSI-2 introduced optional 16 and 32 bit buses called "Wide SCSI." The transfer rate, normally 10 MBPS, can go up to 40 Mbps, when combined with Fast and Wide SCSI, SCSI-2 usually uses a MicroD 50-pin connector with thumbclips. It's also known as Mini 50 or Micro DB50. A micro ribbon 60 connector may also be used.
SCSI-3
Found in many high end systems, SCSI-3 commonly uses a MicroD 68-pin connector with thumbscrews. The most common bandwidth for SCSI-3 is 16-bit with transfer rates at 20 MBPS. Serialbus and fiber channel protocols are in development. It's also known as Mini 68.
Notes: If you are using SCSI-3 to SCSI-2, check your equipment to determine if it terminates the 16 unused leads. If not, a termination may be required.
Your system's performance depends on the quality of your cables, and connectors. Our high quality cable assemblies reduce the possibility of system failure.
Peak performance is also tied to correct cable lengths. As cable runs become longer, signals weaken and are subject to increased noise. Length is total of the bus.
