Termination
The SCSI bus is a chain of SCSI devices. The devices at both ends of any SCSI chain
must be terminated for the SCSI bus to function correctly. A SCSI device chain can be
configured in three different ways: internal, external and an internal/external SCSI
device chain..
Remember an ATTO ExpressPCI Ultra2 SCSI adapter is also a SCSI device and may
require termination depending upon the configuration. Be sure to use the correct
terminator. Single-ended, low voltage differential and differential SCSI buses use
different types of terminators that should not be mixed.
Terminating the Single-Ended ATTO ExpressPCI UL2S and
UL2D
Your ATTO ExpressPCI Ultra2 SCSI host adapter incorporates advanced termination
circuitry that allows it to automatically configure its own termination.
