Welcome to our page regarding Cables, Connectors, and terminators
Host Adapters Page

SCSI Interface (Small Computer Standard Interface)
There are a number of connectors, including high-density, low density, Mac, PowerBook, Wide, and SCSI-3. Part of the aim of this page is to clarify the various SCSI cable connectors and associated terminators and adapters

1. Centronics 50 pin aka Low density, SCSI-1, ~ 2. 5" 50 pin connector
Typically used in older peripherals and host adapters such as the Adaptec AHA-1540, and physically large equipment

2. High Density , SCSI -2, 50 pin ~ 1. 375 "
Typicall used in newer card such as the Adapatec AHA-2920, AHA-2940 aka SCSI-2

3. Mac SCSI ~ 1. 5 " 25 pin
This is the connector used to connect to the Macintosh computers, and also used in Zip drives and adaptec AHA-1502

4. Mac Powerbook

5. Wide, SCSI-3, 68 pin

Typical internal cables are 50 or 68 pin ribbon cable.

Terminators:

The SCSI chain requires termination at bothe ends of the SCSI chain.
Host Adapters are typically self terminating, or jumpered at one end of the chain, if no internal SCSI devices are connected,
otherwise the Host Adapter is in the middle of the chain, and the last internal device requires termination, typically by jumpers.
The last external SCSI device on the chain also requires termination, typically by terminator connector or switch setting. Depending on the length of the chain, an active rather than passive terminator is suggested, and this requires termination power from the SCSI device.

There are physical limits to the SCSI chain of 6 feet and of course 7 units.
