Active Terminators provide a much more stable form of termination than Passive Terminators and are suitable for those longer, higher data rate SCSI cable runs. Terminators designated as 'Active' use a voltage regulator to optimize signal voltage as opposed to those designated 'Passive', which only regulate the line impedance.
- HP68 Male
Probably the most common SCSI connector used today. Used on all SCSI Wide applications and some old DEC single-ended SCSI
this connector provides a highly secure connection. Used for scsi-3 applications: scanner, removable
storage drive, controller, external cdr/cdrw, ultra/2. The HP68 connector has
68-pins arranged in two rows one on top of the other. The top row has 34 pins and
the lower row has 34 pins.
- SCSI 3 - Before Adaptec and later SCSITA codified the terminology, the first parallel SCSI devices
that exceeded the SCSI-2 capabilities were simply designated SCSI-3. These devices, also
known as Ultra SCSI and fast-20 SCSI, were introduced in 1992. The bus speed doubled again
to 20 MB/s for narrow (8 bit) systems and 40 MB/s for wide. The maximum cable length
stayed at 3 meters but ultra SCSI developed an undeserved reputation for extreme sensitivity
to cable length and condition (faulty cables, connectors or terminators were often to
blame for instability problems).
