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.

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).
