1-1 Unpacking Your AP-10 SCSI PCI
Before installing your SCSI board, verify that the following
items are included in the packaging carton:
• One AP-10 SCSI PCI board
• One internal SCSI 50-pin ribbon cable
• Drivers and utilities software
• This user’s manual
Please consult your dealer if any item is damaged or missing.
1-1.1 Static Electricity Precaution
One of the routine precautions you must be aware of when
working with computer components is the problem of static
electricity discharge.
Leave the board in its static-resistant bag until you
are ready to install it.
WARNING:STATICELECTRICITYDISCHARGEmay
permanentlydamageyoursystem.Inordertoavoidpossible
static electricity discharge during installation procedures,
please follow the guidelines below:
•Discharge any static electricity build up in your body by
touchingalargegroundedmetalsurfaceorthecomputer’s
case (if plugged in), for a few seconds.
•During installation procedures, avoid any contact with
internal parts. Handle boards only by their edges.

1-2 Introducing Your AP-10 SCSI PCI
Your AP-10 SCSI PCI is a high performance PCI-bus Bus
Mastering SCSI adapter which can connect up to seven SCSI
devices. It is an all-purpose SCSI adapter for users who want
to take advantage of the benefits offered by SCSI technology
such as multitasking, multiple device support, ease in using
portabledevices,betterdataintegritythrough parity checking
and fast data transfer rate. Plus, it supports the most efficient
Bus Mastering DMA data transfer method so you can get the
maximum performance from iomega®/SyQuest®removable
cartridge drives, scanners, tape drives, CD-ROMs, CD-R/RW
drives, MO drives and many more.
The AP-10 SCSI PCI supports 32-bit data transfer across the
PCI bus at speeds up to 133MB/sec and synchronous burst
data transfer rates up to 10MB/sec on the SCSI bus.
You may be surprised to learn that hard disk drives are the
only devices that can really take advantage of higher data
transfer rates supported by the faster Ultra SCSI adapters
Serial No. Part No.

AP-10 SCSI PCI User's Manual
(20MB/sec for Ultra SCSI and 40MB/sec for Ultra Wide SCSI
drives). To get the optimum performance from other SCSI
devicessuchasfastSCSIharddiskdrives,removablecartridge
drives, scanners and tape drives, 10MB/sec synchronous data
transfer rate is all you need. So, unless your requirements are
for high end data-intensive applications, such as used by
graphics and multi-media professionals (which could benefit
fromthe faster UltraSCSIharddiskdrives), this “all-purpose”
adapter is the ideal, affordable choice for adding SCSI devices
to your system.
The AP-10 SCSI PCI can function as a primary controller (the
on-board SCSI BIOS supports the INT 13h extension which
allows boot up in SCSI only systems); it can also be set as a
secondary controller in a system which already has a primary
IDE,ESDIorMFMharddrivecontrollercard;oritcanbesetto
boot from a CD-ROM.
Regardingtermination,yourAP-10SCSIPCI boardisdesigned
withanactiveterminationfeature,whichautomaticallysetsthe
proper termination of the board for you. Compared to passive
termination, this built-in auto-termination provides the most
accurate termination by adjusting to the actual voltage signal
levels on the bus.
The AP-10 SCSI PCI also comes with a full complement of
softwaresupport.Plus,aconvenienton-board(ROMresident)
SCSI BIOS Setup Utility allows for easy configuration and
optimization of the board and peripheral devices.

Chapter 2
Quick Installation
This chapter is a quick reference guide for installing your AP-
10 SCSI PCI board for proper operation in your system.
This information assumes you are familiar with SCSI device
termination and installing boards in a computer. If you are a
new user, or find you need more detailed information, please
refer to Chapter 3: Introduction to SCSI for an overview of the
SCSI bus, cabling and rules for termination, and Chapter 4:
Hardware Installation, to install the SCSI board in your system.
Theinstallationofthe AP-10SCSIPCIboardisfullyplug-and-

the system BIOS automatically, there are no jumpers to set.
2-1 Installing Your AP-10 SCSI PCI
Perform the following instructions to install your AP-10 SCSI
PCI board:
Like all electronic equipment, your SCSI board is static
sensitive.Beforeopeningtheanti-staticpolybaginwhichit
is packaged, discharge static electricity by touching the
computerchassis.Keeptheboardinitsconductivewrapping
until it is ready to be installed in your system.

Do not use differential devices; use only
single-ended devices.
SCSI ID: Ensure each SCSI device has a unique SCSI ID.

Quick Installation
Termination: The AP-10 SCSI PCI will automatically set
its own termination correctly. However, you must ensure
that all other SCSI devices are properly terminated. Only
the last device on the internal and/or external SCSI Bus
shouldbe terminated. All otherSCSI devicesshould NOT
be terminated. (Refer to Chapter 3.)
Always use “Active Terminators” on devices that have this
feature. Refer to device documentation if necessary.
Internal Devices:

with the board to connect 8-bit SCSI devices.
(Ifyouplantoconnectmorethantwodevices,seeyourlocaldealer

Make sure pin 1 on both connectors are matched when
making the connections. (The side of the cable with the
colored stripe running down its length indicates the pin 1
side of the connector.)
ExternalDevices:
Installation of external SCSI cables can be made after the
cover is replaced. Cabling is limited in length to a total of
9.8feet. The externalcable can bedaisychained to include
up to 7 devices (in combination with internal devices.)
Leave the power OFF. Make sure all signal and power
cables are properly connected.

Introduction to SCSI
Chapter 3
Introduction to SCSI
3-1 Introducing the SCSI
SCSI,whichistheacronymforSmallComputerSystemInterface,
is a specification for a peripheral bus and command set. The
SCSI specification defines a high performance interface that
distributes data among peripherals independently of the host,
thereby freeing the host computer for more user-oriented
activities.
SCSIofferstheadvantageoflettingyouconnectuptoseven(15
on wide SCSI) internal and/or external SCSI devices to one
host adapter card. This enables you to use the other available
expansionslotsforotheradd-oncardssuchasinternalmodem
or network cards.
AnotherSCSIadvantageoverotherperipheralinterfacesisthat
SCSI is designed to keep computers in step with advancing
technologies. SCSI enables host computers to connect with
virtuallyanySCSIperipheraldevicewithoutalwayshavingto
overhaulsystemhardwareand/orsoftware.Thehostcomputer
doesnothaveto“learn”anewwaytocommunicateeverytime
aperipheraldeviceisadded–theconflictingissuesofinterrupts
and COM/LPT port assignments are eliminated by the
independentscheme ofassigninga unique SCSIID number to
each device on the SCSI bus.
However, one important requirement (defined by the SCSI
specification) is the rule of device termination:
Whenadding SCSI devices,you mustensure that
the devices on both ends of the SCSI bus are
terminated and that all devices in-between are
NOT terminated.
