Model DC-390U2W can support SCSI-2, Ultra-Wide and Ultra2
devices. The Symbios 53C141 Isolation IC allows all devices to work
at their full speed with no degradation of performance to the Ultra2
bus. DC-390U2W ships with Internal Ultra2, Ultra-Wide and SCSI-2 cables, as well as an Ultra2 Terminator and an Internal-to-External
SCSI-2 adapter bracket.
