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 .

Half Pitch 50 Male (Micro DB50 Male)
Used for scsi-2 applications: scanner, removable storage drive, controller, external
cdr/cdrw. The Micro DB50 connector has 50-pins arranged in two rows one on top of
the other. The top row has 25 pins and the lower row has 25 pins. Most 8-bit SCSI FAST
(up to 10 Mbytes/sec) computers and host adapters use this 50-pin High-Density connector.
Commonly used on Apples and Mac, and some older Sun 8-bit workstations. This connector is seen increased use on Scanners
and Iomega Zip Drives.
- SCSI 2 - This standard was introduced in 1989 and gave rise to the Fast SCSI and Wide SCSI variants.
Fast SCSI doubled the maximum transfer rate to 10 MB/s and Wide SCSI doubled the bus width
to 16 bits on top of that (to reach 20 MB/s). However, these improvements came at the
minor cost of a reduced maximum cable length to 3 meters. SCSI-2 also specified a 32-bit
version of Wide SCSI, which used 2 16-bit cables per bus; this was largely ignored by SCSI
device makers because it was expensive and unnecessary, and was officially retired in
SCSI-3.
