INTRODUCTION

The DC-390U2B/W is an Ultra2 SCSI (Small Computer System Interface) bus to PCI bus
host adapter, which complies to the PCI 2.1 specification with Plug-&-Play (PnP) readiness.
Installing this adapter in your PCI system allows connection of up to 15 SCSI devices.

Your DC-390U2B/W is a 16-bit, Low Voltage Differential (LVD) / Single Ended (SE)
SCSI solution for your computer. It can support both legacy Fast SCSI and Ultra SCSI
devices, as well as the newest LVD Ultra2 SCSI devices.

The DC-390U2B/W supports ASPI (Advanced SCSI Programming Interface) managers for
most of the operating systems available today to assure operation with popular third party
applications.

Device drivers are also supported for the major operating systems for compatibility with a
full range of SCSI peripherals including CD-ROMs, Photo CDs, tape backups, scanners,
removable media and SCSI hard drives.

Installing the Adapter

Important: Handle circuit boards by the edges or bracket. Touch the bare metal of your
computer case before handling any circuit boards to prevent static discharge damage.

1. Power OFF and unplug your system.

2. Remove the computer cover. Refer to your system user’s manual for instructions.

3. Align the gold-fingered edge on your card with an empty PCI expansion slot and gently

insert it into place. You may need to remove the cover from the rear of the PCI
expansion slot that you selected.

4. Replace the screws to secure the card retaining bracket in place.

Setting the SCSI IDs

Each SCSI device attached to the SCSI card, as well as the card itself, must be assigned a
unique SCSI ID number. SCSI ID 7 is preset to the SCSI card, giving it the highest priority
on the SCSI bus.

The SCSI IDs of your peripheral devices are usually set with jumpers or with a switch on
the peripheral. Refer to the peripheral‘s manual to determine the ID and how to change it.
