The FlashPoint adapter complies with PCI Specification Rev. 2.1, operating
at the maximum PCI local bus rate of 133 MBytes/sec in 32-bit data burst
mode. Mylex host adapters offer exceptionally high product reliability due to
reduced component count and lower power consumption. Minimized
command overhead results in faster command execution. The adapter BIOS
supports disk drives, even those with greater than 8 GBytes capacity.

Manual No. 3000863 1-1

Configuration

Configuration

Plug and Play Operation. FlashPoint adapter configuration is handled by
the PCI motherboard. Operating parameters can be adjusted using
AutoSCSI, a menu-driven utility residing in the adapter’s Read Only
Memory (ROM).

Features

The FlashPoint PCI host adapter has the following features:

• Fast data transfer rates

The FlashPoint supports standard data transfer rates including Fast
SCSI-2 at 10 megabytes per second and Ultra SCSI rates at 20
megabytes per second.

• SCAM Support

The FlashPoint supports the SCSI-3 SCAM (SCSI Configured
Automatically) ConLevels 1 and 2 protocols for SCSI ID assignment.
SCAM devices do not require manual SCSI ID assignment. The
FlashPoint adapter assigns a SCSI ID to the de vice as requir ed. See the
owner’s manual for your peripheral devices to determine whether or
not they support SCAM.

• SmartTerm

The FlashPoint has no onboard jumpers. With SmartTerm, the
FlashPoint adapter determines the configuration of the daisy chained
devices, and self-terminates as required. See the owner’s manual for
your SCSI devices to determine how they support termination.

•SeqEngine

SeqEngine provides automated SCSI command processing which
reduces SCSI command overhead by minimizing the need to interface
with the host processor. This results in improved performance.

Introduction

PC-DOS, MS-DOS and Windows. Your host adapter’s onboard BIOS
allows you to attach up to seven SCSI disk drives without additional
software under PC or MS-DOS 5.0 and above. Earlier versions of DOS only
allow support for up to two hard disk drives.

Mylex offers device drivers that support ASPI (Advanced SCSI Program
Interface) for configurations where more hard drives are needed than your
version of DOS can support. Mylex also offer s CDROM dri ver s for DOS and
Windows.

If you are installi ng other types of d e vices un der DOS and W in do ws, s uch as
a tape backup device or a scanner, you will need to install additional drivers
that support the ASPI interface to operate those devices. Those drivers are
usually available packaged with the device or from third party sources.

Installation Tools

Warran ty Information

If damage to the board has occurred, return it in the protective envelope and
original packaging with this manu al to your Mylex board supplier. The
shipping agent should also be notified if the unit has been damaged during
shipment. The Mylex warranty conditions are given in the back of this
manual.

Installation Tools

The following items may be needed to assist with installing the adapter into
your system:

• Small screwdriver

• Host system hardware manuals and manuals for the peripherals being
installed.

Setting the SCSI Device ID

Each SCSI device is assigned a unique SCSI ID ranging from 0 through 7.
Most SCSI peripheral devices are shipped with a preassigned SCSI ID
number. Your FlashPoint is , by default, SCSI ID 7.

If you need to change the SCSI ID for a peripheral device, refer to the
instructions in its owner’s manual. A SCSI ID jumper or switch is usually
located on the peripheral’s back panel.

T o change you r adapter SCSI ID use the V iew/Modify Adapter Configuration
option on the AutoSCSI’s Adapter Configuration Menu (Chapter 3, “Adapter
and Device Configuration”).

☛

Note

FlashPoint LT allows the user the option of selecting
the boot drive and specifying its SCSI ID through
AutoSCSI. If the SCSI ID of the boot drive is set to
zero then BIOS looks for the boot drive by scanning
devices according to their SCSI ID, starting at SCSI
ID 0. In this case, mak e sure that your bo ot device has
the lowest SCSI ID.

2-2 FlashPoint™ LT BT-930 User’s Manual

Installation

SCAM Support

The FlashPoint adapter supports SCAM Levels 1 and 2. If your peripheral
device supports SCAM, the FlashPoint adapter will determine an available
SCSI ID and assign it to the device.

SCSI peripheral devices that do not support SCAM (legacy) are shipped with
a preassigned SCSI ID number . You can change this ID if necessary . A SCSI
ID switch is usually located on the back panel of such devices. It may be in
the form of a jumper or a switch whose setting indicates the SCSI ID. If you
need to change the SCSI ID for the other peripheral devices, refer to the
instructions in the owners manual for the device.

Terminating SCSI Devices

The SCSI devices connected on the ends of the cable of a SCSI bus must
have terminators installed or enabled. Terminators, which can be connected
to either SCSI devices or SCSI cables, are required for reliable operation of
the SCSI bus.

☛

Note

Pass through cable t erminat ors may not prop erl y
terminate the device. For greater reliability, Myle x
recommends the use of active terminators for all
devices.

If more than two SCSI devices are connected in a SCSI daisy chain, disable
the termination on the middle device(s).

The FlashPoint is equipped with SmartTerm™ and does not require any
physical configuration for termination. SmartTerm requires no user
interaction and automatically enables or disables the FlashPoint termination
depending on the configuration of the SCSI bus in the system.

☛

Note

There are devices on the market, such as some pass
through terminators and de v i ces with 26-pin DB
connectors, that do not conform to SCSI
specifications. With such devices on the cable, the
SmartT er m log ic on th e FlashPoint LT board does not

Installing Your FlashPoint

work properly. To overcome this problem, the
FlashPoint adapters provide an AutoSCSI option to
disable onboard termination.

Installing Your FlashPoint

Step 1: Prepare the host system and the adapter

When you are ready to begin, power down the host system.
Referring to your host system owner’s manual, remove the covers to open

the case to gain access to the motherboard and expansion slots as shown in
Figure 2-1.

If the computer has been on, wait a few minutes until the power supply case
has cooled down inside the computer. If the power supply case is cold, touch
it to discharge any static electr icity t hat may be on your clothes or body.

Figure 2-1. Remove the Cover and Bracket

To install the adapter card, remove the mounting screw and the existing
bracket from the rear panel behind the selected PCI slot.

Align the mounting bracket, and reinstall the mounting screw.

Figure 2-2. FlashPoint adapter Installation

m Caution

Make sure that the board is properly seated in the slot.

Step 3: Install internal devices and cables

Internal devices require a 50-pin flat ribbon cable. Use the ribbon cable
included with the FlashPoint to install o ne or two internal devices. Install
one end of the ribbon cable to the 50-pin double-row SCSI connector on the
FlashPoint host adapter (see Figure 2-3).

Before plugging in the cable, check that the “▼” mark molded on the
connector or the colored stripe on the cable (indicating the location of Pin 1)
matches Pin 1 of the connector on the board.

Manual No. 3000863 2-5

Installing Your FlashPoint

Figure 2-3. Installing Internal Devices and Cables

When installing one internal device, connect it to the end of the cable and
terminate the device. Consult the owners manual for information on how to
terminate the device.

If a second internal device is to be included in the internal installation,
terminate only the device at the end of the cable. If the default config uration
for the device in the middle of the cable is terminated, consult the owner’s
manual to find out how to disable termination.

Be sure each device has a unique SCSI ID assigned. See “Setting the SCSI
Device ID” on page 2-2 in t his chapt er for mor e in formati on about assign ing
SCSI IDs.

Install the LED Cable (Optional)

Insert the connector from the drive activity LED on the front panel of the
host to the connector on the FlashPoint as shown in Figure 2-4. This
connector is reversible and may be plugged into the connector in either
direction. If your system has a two-pin LED drive acti vity connector, use the
first two or the last two pins. The following diagram shows the connector
pin-outs.

Installation

Figure 2-5. Installing External Devices and Cables

External devices are connected using a 50-pin cable with a high-density
SCSI-2 connector.

Manual No. 3000863 2-7

Installing Your FlashPoint

Connect one end of the SCSI cable to the adapter’s SCSI connector and the
other end to the SCSI device as shown in Figure 2-5. Devices are attached in
a daisy chain configuration until a maximum is reached. The last device in
the daisy chain must be terminated. All intermediate devices should not be
terminated or should have termination disabled.

Be sure each SCSI device has a unique SCSI ID assigned. Refer to “Setting
the SCSI Device ID” on page 2-2 below for more information about
assigning SCSI IDs.

A Note about SCSI BUS T ermination

The FlashPoint adapter supports both internal and external devices. If more
than two SCSI devices are connected in a SCSI daisy chain (the FlashPoint
adapter card is considered one device in the chain), remove or disable the
terminator resistor pack on the middle devices.

• When attaching internal devices only, the last device in the chain must
be terminated. The FlashPoint adapter automatically terminates the
other end of th e SCSI bus.

• When attaching external devices only, the last device in the chain must
be terminated. The FlashPoint adapter automatically terminates the
other end of th e SCSI bus.

• Both internal and external devices can be attached to the same
FlashPoint adapter. The last device at each end of the SCSI bus (one
internal end and one external end) must be terminated. (See Figure 2-

6.)
The FlashPoint automatically disables its termination to ensure SCSI
bus integrity.

Maximum SCSI BUS Lengths

The SCSI bus may not exceed the maximum lengths listed in Table 2-1. The
limitations listed in this table are for 8-bit data path SCSI d evices. Wide
SCSI (16-bit data path) is not supported by the FlashPoint LT host adapter.
The total length of the SCSI bus is made up of all the cables that interconnect
the FlashPoint to all the devices in the daisy chain configuration including
the length of the internal ribbon cable, if it is used (see Figure 2-8). If the
SCSI bus exceeds the recommended length, the SCSI devices may display
unpredictable behavior.

Step 5: Power up the System

Once the adapter is installed, power up the system. As the system powers on,
the BIOS performs a self test. Any error conditions that arise from the self
test are displayed on the start-up screen. Should you encounter any
conditions that you can not resolve, contact Mylex Customer Service at the
numbers and/or addresses listed in Appendix B of th is manual.

Step 6: Ver if y devices

The FlashPoint adapter comes with an o nboard configuration utility,
AutoSCSI, which resides in Read Only Memory (ROM). AutoSCSI is a
menu-driven utility for configuring Mylex SCSI host adapters. You can use
AutoSCSI to set or change SCSI and BIOS-related configuration parameters.
In addition to simplified configuration, AutoSCSI offers diagnostics. See
Chapter 3, “Adapter and Device Configuration,” for information about how
to use this program to verify the connected devices.

Step 7: Set up hard drives

Most off-the-shelf hard drives are preformatted. If this is not the case, or
your drive requires a low-level format as indicated by error conditions, use
the low-level format utility included with the onboard AutoSCSI utility
described in “Performing a Low-Level Format of a Device” in Chapter 3 of
this manual.

Once the hard drive is low-level formatted, you will need to create a partition
(or multiple partitions) and high-level format the partition(s) to prepare your
drive for operating system installation. Your operating system may
incorporate these partitioning and high-level format functions as part of its
installation or may offer them as separate utilities. For example, DOS
provides FDISK and FORMAT in its utilities suite.

Step 8: Install device driver s

In addition, you may need to install device driver software if your operating
system does not include the required drivers for your installation as
discussed in Chapter 1.

Driver installation usually takes place as part of operating system
installation. Refer to your operating system installation instructions and the
FlashPoint Software User’s Guide for details.

need to adjust the adapter’s configuration, the
AutoSCSI utility provides fast and easy configuration
capabilities.

The BIOS on the PCI motherboard automatically configures the following
parameters at power-up:

• Adapter I/O Port Address (Base Address Registers)

• BIOS Address (ROM Base Address)

• Interrupt Channel (IRQ)

Use AutoSCSI to further configure the FlashPoint adapter to suit your
operating environment.

Bringing Up AutoSCSI

AutoSCSI resides in Read Only Memory (ROM). AutoSCSI is a menu­driven utility for configuring FlashPoint adapters. In addition to this utilities

This field shows the base address of the registers the host uses
to communicate with the host adapter. Each board and each
channel within the same host system must have a unique I/O
port address to prevent hardware conflicts. On PCI adapters, the
host system’s BIOS assigns the I/O port address during the boot
sequence.

This field shows the PCI bus number.
This field shows the PCI device number
The channel on the FlashPoint LT that is being configured.
This field shows the hardware interrupt line (IRQ) number that

the adapter uses to generate interrupts to the host. The adapter
issues an interrupt whenever it requests attention from the host.
On PCI adapters, the host system’s BIOS assigns the IRQ
value.

This field indicates whether the adapter’s automatic SCSI
termination, SmartTerm is turned on or not. SCSI devices are
daisy-chained together and a terminator is required at each end
of the chain. Should the selected adapter be at t he beginning or
the end of the SCSI chain, this value must be set to AUTO.
Termination is enabled/disabled automatically by the FlashPoint
host adapter.

When there are multiple adapters, the adapter with the highest BIOS address
controls the process of reading data from other adapters for configuration
information.

Troubleshooting

Troubleshooting Guidelines

If you experience a problem with adapter operation when all the installation
steps are completed, refer to the following guidelines.

Check the Installation Procedures

• Be sure all connectors are firmly seated.

• Check the orientation of the SCSI cable. Be sure that Pin 1 o n the cable
matches Pin 1 on the adapter/SCSI device connector.

• Check that the adapter and attached devices have unique SCSI IDs.

• Be sure that the SCSI ID for the boot hard drive is the same as the ones
in the AutoSCSI option. If the ID 0 (zero) is specified in that option,
BIOS determines the boot drive by scanning SCSI devices starting
from ID 0. If the boot drive number is higher than the other drive,
change it to a lower value.

• Be sure that you’ve followed SCSI termination rules.

• Check that you have correctly set the CMOS hard drive option to not
installed in your system SETUP file.

Verify Host Adapter Configuration Settings

☛

Note

Although IRQ and BIOS Addresses are autom atically
configured in a PCI system, differences in PCI bus
implementation may result in conflicts among
adapters from more than one manufacturer.

• Check the adapter’s IRQ setting. Verify that each installed card has a
unique IRQ value. There may be a conflict with ISA (non-PCI)
adapters. If this occurs, you must change the non-PCI adapter’s IRQ
setting.

Manual No. 3000863 4-1

Troubleshooting Guidelines

For example, you have installed the ASPI DOS driver in the
CONFIG.SYS file and are attempting to boot from a SCSI disk drive.
The system begins the boot sequence, the b anner is displayed , attached
SCSI devices are recognized and posted on the display. A message is
then displayed indicating that th e SCSI DOS driver is being installed,
however, the system appears to suspend operation with no further boot
activity. In this sequence of operation, BIOS does not require IRQ
support, so it proceeds without problem. The DOS driver requires the
IRQ and quickly stops operation after being installed because of a
possible IRQ conflict.

• Verify AutoSCSI configuration. If you have changed adapter SCSI-

or BIOS-related parameters via AutoSCSI, use the Load Factory
Default option on the AutoSCSI Adapter Configur atio n Menu to return
the board to factory-set defaults. Check that you have selected
operating parameters that do not conflict with those of other installed
adapters before re-entering your changes.

Check Device Driver Compatibi lity

• Check that you have installed no more devices than your operating
system or driver can handle. For example, pre-DOS 5.0 versions of
DOS can handle only two hard drives. To handle more devices, you
must install additional drivers.

• Under DOS, be sure that you ha ve installed dri v ers appropr iate for each
installed device. For example, you cannot operate a CDROM device
without installing a CDROM driver for it. Mylex provides a DOS
CDROM driver. Refer to driver installation for further details.

• Be sure you have compatible device driver software installed.

Verify SCSI Device Configuration and Connectivity

Verify that the SCSI cabling is correctly attached and that the adapter can
communicate with a selected device by performing the following:

• Check the adapter’s ability to communicate with attached devices.
Invoke AutoSCSI, and select the SCAN SCSI Bus option on the SCSI
Device list. This option will scan the SCSI bus displaying the message
shown in Figure 4-1. When the scan operation is complete, it registers
all the SCSI devices and displays the device information. If the device

4-2 FlashPoint™ LT BT-930 User’s Manual

Troubleshooting

information is displayed without error, then the adapter is properly
communicating with the SCSI devices.

Figure 4-1. Device Scanning Dialog Box

If an attached SCSI device is not recognized, verify that each device
has a unique SCSI ID. The host adapter is set to SCSI ID 7 by default.

Disable Fast Transfer Rate. Some SCSI de vi ces may not be capable of
negotiating a data transfer rate of 20 /10 MBytes/sec. If a d evice cannot
support the higher rate, it is supposed to reject that value and propose a
lesser value it can support. Some older SCSI devices when requested to
negotiate at 20/10 MBytes/sec will halt operation. Try selecting a lower
negotiating data transfer rate or set the requested transfer rate to Async
in the View/Modify Device Configuration menu.

Motor Spin -U p. Some SCSI disk devices may not be configured to
spin-up on power-on or upon reset. This will cause an error if the
operating system attempts to access this device. When this occurs,
enable the Motor Spin-Up option in the AutoSCSI View/Modify
Device Configuration menu. If this option is enabled and the selected
device does not require this option to be enabled, the device will
probably ignore it.

Power. Be sure that all external SCSI devices a re secur ely co nn ected to
a power source.

Troubleshooting Startup

At system startup, the FlashPoint adapter performs a self-test, runs tests on
the SCSI bus, and performs SCAM on the SCSI bus devices. As these
operations are executing, screen messages appear briefly. When all the
operations are complete, a BIOS installation completion message is
displayed and your system should continue to boot. If the startup operations
do not complete successfully, an error message may be displayed. There are
also conditions under which an operation will not complete successfully and
the system will hang before an error message can be displayed. System hang

Questions & Answers

Q. Why does the “NO ROM BASIC” message appear
when booting up?

A. The DOS partition may not be activated, run the MS DOS FDISK utility
and set the partition active. Refer to your MS DOS reference manual for
specific instructions on activating a DOS partition using the FDISK
command.

Q. Why is the message “Missing Operating System”
displayed during boot, but the hard drive is still seen
by the controller?

A. Check for the active partition. High level format the partition with the
“format C:/s” option. Note, this will erase any data currently on yo ur hard
drive. If the drive was previously used on another controller, you may need
to perform a low-level format and then prepare the drive with DOS Fdisk
and Format utilities. If the mapping mode has been changed since the last
hard disk partitioning, perform another Fdisk an d Format.

Q. My system displays a “Har d Disk F ailure” messa ge
during boot up, what can I do to correct it?

A. Check all cables and drive jumpers. Make sure the drive for the C: drive
is “Type 0" or “Not Installed” in System CMOS if no IDE is installed.

Q. When my system boots up, the banner shows 6
drives, but I only have 1 drive. What is wrong?

A. Check that the drive is not the same SCSI ID as the SCSI controller,
which defaults to ID 7. Make sure your drive is set to SCSI ID 0.

Manual No. 3000863 Q&A-1

Q. How can I use a CDROM drive wi th Mylex contr oller
card in MS-DOS?

A. In DOS, make sure the SCSI ID for the CD-ROM is higher than the disk
SCSI ID. Connect the CD-ROM in the SCSI chain so that it is properly
terminated. Then add these two lines to your CONFIG.SYS.

device=c:\path\flashpt.sys /d

Q. When I load the FLASHPT.SYS driver in the DOS
CONFIG.SYS, the system hangs.

A. Do followings:

1. Make sure the IRQ settings are configured properly. In the system
CMOS under PCI option, there is an IRQ setting. Make sure an IRQ is
being assigned to the Mylex slot.

2. Try a different IRQ. For example, i f you are using IRQ 12, try IRQ 11.
Make note of the first requirement above, make sure it applies when
you try a different IRQ.

3. Get another copy of the latest versio n of FLASHPT.SYS and try it. The
original file may be corrupted. Copies of this file can be obtained in our
BBS, FTP site, or WWW page.

Q. Why I am getting slow transfer times with my new
FAST SCSI-2 hard drives .

A. Make sure the drive is jumpered FAST SCSI-2 and active termination.
Also check that the controller has both Synchronous Negotiation and Fast
Data Transfer enabled.

Q&A-2 FlashPoint™ LT BT-930 User’s Manual

Q. I am connecting a removable drive to the Mylex
adapter in DOS. What device drivers do I need to
load?

A. In DOS, you need to load DOS Manager drivers in CONFIG.SYS as
follows:

device=c:\path\flashpt.sys /d
device=c:\path\btmdisk.sys

After that run BTFDISK program to create the partition on the drive
connected to second card and use the DOS FORMAT command to format
the drive.

Q. I am connec ting a SCSI tape drive to the Mylex
adapter. What device driver do I need to load?

A. You need to load DOS Manager driver in CONFIG.SYS as follows:

device=c:\path\flashpt.sys /d

You also need tape backup software.

Q. I have a large capacity (more than 1GB) drive.
When I run FDISK, it recognizes only 1 GB capacity.
What is the problem?

A. Make sure you enable the DOS > 1 GB switch on the adapter. If you plan
to run NetWare, leave this option off and create your DOS partition in the
first 1G.

Q. I have a floppy tape backup and it runs very slowly
with the Mylex SCSI adapter. What should I do?

A. When you load DOS manager, use the “/n04” switch to reduce bus on
time from default 11us to 4us.

Manual No. 3000863 Q&A-3

Q. Why does my system lock up on bootup after
connecting to an external SCSI device?

A. Double check for proper SCSI bus termination and check connections and
cabling.

Q. I added a new SCSI device to one of the Model C
SCSI host adapter s. Either it is not seen or the system
hangs when the host adapter BIOS tries to scan it. Do
I have the proper SCSI bus termination?

A. This problem occurs mainly because the new device is not SCSI II FAST.
You need to change the Enable Fast Transfer option to No in the AutoSCSI
Configuration Menu. Disable the Enable Synchronous Negotiation option
too, if it is not supported by the device.

Appendix A

Small Computer System

Interface (SCSI)

This appendix describes the Small Computer System Interface terms. It is
provided to help you understand the concepts related to SCSI.

What is a host adapter?

A SCSI host adapter is a printed circuit card that provides a SCSI bus
interface to the SCSI devices installed in a computer system. The FlashPoint
host adapter has both internal and external SCSI connectors supporting both
internal and external SCSI peripheral devices.

What does SCSI stand for?

SCSI stands for Small Computer System Interface. SCSI is a computer bus
interface standard that allows a variety of computer peripheral devices such
as disk drives, CD-ROM drives and tape drives to interface to a host
computer. SCSI-1, SCSI-2 and SCSI-3 are different version of the SCSI
protocol standard.

• SCSI-1 is the original standard that defines the SCSI interface. This
standard includes the definition of a command set, the electrical
characteristics of the SCSI bus, and a 5 megabytes per second data
transfer rate.

• SCSI-2 adds features to the standard including, SCSI linking,
command queueing, and support for additional SCSI peripheral
devices. The SCSI-2 standard also includes the following:

• Fast SCSI is a SCSI data transfer standard that allows up to 10

megabytes per second data transfer on the SCSI bus.

• Wide SCSI provides data transfer at 16-bits for faster data

throughput. Up to 20 megabytes per seco nd is suppo rted on F as t and
Wide SCSI host adapters.

Manual No. 3000863 A-1

What is the SCSI bus?

• SCSI-3 adds more features including Ultra SCSI, SCAM, optional P­cable, the Wide SCSI bus specification that defines an extended
number of devices, support for fiber channel hardware, and a serial
channel interface. It also allows transfer rates of 20 megabytes per
second.

What is the SCSI bus?

A SCSI bus is one or more SCSI peripheral devices and a host adapter
connected together by cables in a daisy chain configuration. The SCSI bus
may include both internal and external devices on one bus.

• A Narrow SCSI bus may have up to eight devices. The host adapter
counts as one device.

• Wide SCSI supports up to 16 devices. Note, however, that Wide SCSI
is not supported by the FlashPoint LT host adapter.

What are the SCSI bus length limitations?

The SCSI bus maximum length is determined by the data transfer rate and
the number of devices in the configuration. Table A-1 lists the data transfer
rates, the maximum number of devices and the maximum allowable cable
lengths for each.

Table A-1. Maximum SCSI Bus Configuration Limits (Narrow Only)

SCSI Type Data Transfer Rate

(in megabytes per

second)

SCSI-2 5 or less 8 6 meters (19.7 feet)
SCSI-2 10 8 3 meters (9.8 feet)
Ultra SCSI 20 4 3 meters (9.8 feet)
Ultra SCSI 20 8 1.5 meters (4.9 feet)

Cable Length

Remember when measuring the length of the SCSI bus, you must include all
the connecting cables including the internal cable if it is used to connect
internal devices.

A-2 FlashPoint™ LT BT-930 User’s Manual

Small Computer System Interface (SCSI)

What is a Daisy Chain Configuration?

A daisy chain is where the bus is created by attaching the first device in the
chain to the second device and the second device to the third device and so
on until all the devices are chained together.

What is a SCSI ID?

A SCSI ID is a unique identifying number ranging from 0 to 7. (0-15 for
Wide SCSI) This number is assigned to a SCSI device on the SCSI bus. The
SCSI ID identifies the device and determ ines the priority of the de vice on the
SCSI bus. The priority of the de v i ce on th e bus is important when more than
one device attempts to access the bus at the same time. The higher the SCSI
ID number the higher the priority of the device during bus access. The
FlashPoint adapter is preassigned SCSI ID 7, giving it the highest SCSI bus
priority.

What is termination?

T ermination is an electrical characteristic of a SCSI bus. In order for devices
to transmit and receive data and signals reliably over the SCSI bus, the bus
must be properly terminated at both ends.

Devices can be terminated in a variety of way:

• The FlashPoint adapter supports SmartTerm. This means that the
FlashPoint adapter determines where it is located in the daisy chain and
either enables or disables its own termination as required.

• Peripheral devices can be terminated using a sev eral dif feren t methods.
Some require termination plugs, thumb wheel setting, and/or DIP
switches. Refer to the documentation that accompanies the device to
determine what the termination method is. If the device occupies either
end of the daisy chain, it must be terminated properly in order for the
SCSI bus to function properly.

What kinds of terminators are there?

For external de vices there are SCSI-1 and SCSI-2 type terminators. Standard
SCSI-1 terminators fit into Standard SCSI-1 connector receptacles. SCSI-2
terminators fit into SCSI-2 receptacles.

Manual No. 3000863 A-3

What are SCSI Cables and Connectors?

Internal devices may be terminated using cable terminators, however it is
more likely that an internal device will use some sort of other method of
termination like a resistor pack or a jumper.

When determining how to terminate a de v i ce, e xam ine the device and check
on the manufacturers suggested termination method as described in the
product documentation.

The last device in the chain must be terminated. The terminator may be a
SCSI-2 type terminator or Standard SCSI-1 (Centronics).

The cable to the device may need a SCSI-2 type plug or a Standard SCSI
(Centronics) type plug.

It is recommended that you use active terminators rather than passive
termination.

What are SCSI Cables and Connectors?

There are several types of SCSI cables and connectors.
Cables are used between the devices in a SCSI bus to create the electrical

pathway that connects the devices to the host adapter. The FlashPoint LT
adapter provides for both internal and external device attachment.

Internal Connections. The FlashPoint LT adapter’s internal connector is a
standard 50-pin internal SCSI connector that provides attachment for the 24­inch ribbon cable with two additional de vice connectors. T his ribbon cable is
provided with the adapter. You can connect two internal devices to the
adapter using this cable. Remember when using this cable to connect internal
devices to the FlashPoint adapter, the last device on the cable must be
terminated.

External Connections. The FlashPoint LT adapter’s external connector is a
SCSI-2 50-pin connector. In order to correctly cable devices, you must
examine each device to determine what type of connectors need to be
accommodated.

For example, if the peripheral device you want to attach to the FlashPoint
adapter has standard SCSI 50-pin (Centronics) connectors, you will need to
purchase an adapter cable that has a SCSI-2 connector on one end (to attach
to the FlashPoint adapter external connector) and a SCSI 50-pin (Centronics)
connector on the other end to attach to the adapter.

A-4 FlashPoint™ LT BT-930 User’s Manual

Small Computer System Interface (SCSI)

Each device needs to be examined to determine what type of connector is
required. SCSI cables come in a variety of connector combinations so that
the SCSI bus may be made up of a combination of device types with cable
adapting for the differences between devices.
