SCSI Adapters

Using the correct scsi adapter is crucial to the ability of your scsi drives and peripherals to work properly at their maximum speed -- or at all...
SCSI Adapters have different types of connectors and/or "genders" of connectors on each end. They are used for connecting a device with one type of connector to a cable or other device with another type of connector. Unfortunately there have been quite a few "standard" connectors over scsi's long history. As scsi got faster and "wider", it was necessary to update the connector types to newer, "better", "faster" connector types. So of course with the advent of new connectors came the need for adapters.  An important issue to keep in mind is the "wide" and "narrow" or "high byte" "low byte" problem. "Wide scsi" means 16 bit or 2 "bytes" (8 bits make a byte). Narrow scsi is 1 byte (8 bits). Connecting wide devices to a narrow bus or narrow devices to a wide bus must be done with the proper adapter which takes the termination problems into account. Wide scsi devices will work just fine using only the first byte, and therefore can be used on a narrow bus (cable) as long as their connected using a scsi adapter with high byte termination. Narrow devices can be used on a wide bus, without problems depending on whether or not they are connected to an "LVD" (Low Voltage Differential) segment. Connecting narrow devices to an LVD bus will cause that segment to drop out of LVD mode. Feel free to contact us with your SCSI Connectivity Issue.
