Many devices and peripherals of yesteryear are affixed with Scsi connectors as that was the rage of the times in data transfer. Many devices were associated on a singular bus, with benefits such as fast transmission speeds and reliability. Although it worked with most computer systems, there were some issues with Bios support. There were also no base Scsi software interfaces.
As technology progressed, Usb made its appearance. True to its name, it became the universal connector in the middle of computers, devices and peripherals. Unfortunately, owners of devices and peripherals with Scsi connectors were in a pickle as to how to associate their old external devices to newer computers which sported Usb ports. External devices which had Scsi connectors were regularly scanners, Cd drives, Dvd drives, hard disk drives, movable magnetic media, Mo devices and tape drives. These devices adored Scsi association as fast speeds of data transmission as well as large quantities of data were their mainstay.
Options for Scsi-Usb association are quite limited. Some cable manufacturers have produced a cable with different adapters at both ends to change Scsi to Usb connections. By connecting the Usb end to the Usb port at your computer and the Scsi end to the Scsi port on your external Scsi device, company runs as usual. You can even string a number of devices to your computer via a daisy chain effect. No added configuration is required as it relies on a simple plug and play. Unfortunately these cables make quite a high-priced purchase. Some also don't work with internal Scsi devices namely internal hard drives with Scsi connectors.
To address this issue, some manufacturers have also advanced an interface kit to change Scsi to Usb connections. If you need to copy some old but principal data from your internal Scsi hard drive to your computer, this is probably the best solution. To setup an interface kit for Scsi-Usb connection, you need some basic knowledge in hooking up devices into your computer's internals. You also need to setup relevant drivers into your system. If you are not adequate with this knowledge, it's best to seek the assistance of one who does.
Delving more into Scsi connectors of these hard drives, there are a few variants in the number of pins on the connector itself. Ready as a 50, 68 to 80 pin connector, you need to buy an added adapter to function as an intermediary if it doesn't match the adapter in the interface kit. For instance, your internal Scsi drive may have a 50 pin connector whereas the Scsi adapter in the kit only supports a 68 pin connector. An adapter to attach this 50 pin expedient to the 68 pin adapter is in order.
Although Scsi technology is here to stay, it's obviously being overwhelmed by newer and cheaper technologies. Possibly it's time to bow down to technology and replace your Scsi scanner to one with a Usb connector.
