DC-310 series SCSI Adapter Quick Reference Guide (rev 2.2)

Introduction

The DC-310 series has two adapters: DC-310U, an Ultra-SCSI adapter based on the
Symbios Logic SYM53C860 SCSI Chip, and DC-310, a Fast SCSI-2 adapter based on
SYM53C810 SCSI Chip. Designed to provide a low cost, easy to implement SCSI solution,
this adapter utilises the built-in Symbios Logic SCSI BIOS (SDMS BIOS version 4.x) on
supported mainboards, such as Tekram P5 VX/TX and P6/Pentium_II series.

Fully Plug & Play and PCI 2.1 compliant, enhanced SCSI features include
Disconnect/Reconnect, Scatter/Gather, and Tag Queuing to greatly improve overall system
performance, particularly under multitasking environments.

Jumper-less hardware design, Active SCSI Bus Termination, and 32-bit PCI DMA Bus
Mastering are a few more of the advanced features built-in to the DC-310 series adapters,

providing the best performance and ease of use possible.

PCI Integration

• Full 32-bit PCI DMA bus master

• Jumper-less design

• Active SCSI bus termination (* DC-310: optional)
∗ Termination is required for both ends of a SCSI bus.
∗ DC-310U: Need to do nothing for the termination on the DC-310U,

since it’s equipped a pair of Active Terminators on U1B & U2B.

∗ DC-310: (Same to DC-310U if a pair of active terminators are

installed on the U1B & U2B). If it’s Passive Terminators, which
are resistor arrays, used on RP1/RP2/RP3, you’ll need to remove
them if the DC-310 is not located at one end of the SCSI bus.
White dot on the resistor array must point to the small box while
installed.

Reliability

SYMTolerANT technology with:

• Active negation of SCSI Data, Parity, Request, and Acknowledge

signals for improved fast SCSI transfer rates.

• Input signal filtering on SCSI receivers improves data integrity,

even in noisy cabling environments.
