Tekram DC-395UW Ultra Wide (SCSI Host Adapter)

DC-395UW

Tekram launches a series of SCSI hosts adapters using Tekram's SCSI ASIC design from Ultra SCSI up to Ultra Wide SCSI.

Based on Tekram’s TRM-S1040 SCSI chip, the DC-395UW/DC-395F expands SCSI bus bandwidth to a maximum 40MB/s data transfer rate and 20MB/s for DC-395U.

The DC-395 Series controllers support ASPI (Advanced SCSI Programming Interface) managers for the following operating systems: MS-DOS, Windows 95/98/NT, OS/2, SCO Unix, NetWare, Linux and FreeBSD. Other enhanced SCSI-2 features such as Scatter-Gather and Command-Tag Queuing are supported.

Features

• Flash BIOS available.
• High speed 32-bit PCI bus master DMA transfers up to 133MB/s in burst mode.
• Max transfer rate supported are 20MB/s for DC-395U Ultra SCSI and 40MB/s for DC-395UW, DC-395F ultra-wide SCSI.
• Maximum devices supported are 7 for DC-395U and 15 for DC-395UW & DC-395F.
• Level triggering allows interrupt sharing between multiple adapters.
• PCI 2.1 compliant with full plug & Play readiness.
• User friendly PCI configuration utility for quick and easy adapter installation and system configuration.
• PCI power management supported.
