Remote LED Option
-----------------
LED (user supplied) connected to Remote LED
Both LEDs (on Device Electronics board and remote location) are
enabled.
Remote LED not connected (default)
LED on Device Electronics board enabled.
Spindle Synchronization
-----------------------
The Rotational Position Locking field (MODE SELECT command, Page Code
04h) is used to specify spindle synchronization operation.
Unsynchronized: If the drive is set to Unsynchronized (RPL = 00b), it
ignores the SLAVE SYNC signal.
Slave: If the drive is set to Slave (RPL = 01b), it does not generate
the MASTER SYNC signal or the SLAVE SYNC signal but synchronizes its
index to the SLAVE SYNC signal supplied by an external source. Signal
termination is placed on the SLAVE SYNC signal at the first and the
last device in the chain only.
Master: If the drive is set to Master (RPL = 10b), it generates the
SLAVE SYNC output signal for use directly by the slave drives. Signal
termination is placed on the SLAVE SYNC signal at the first and the
last device in the chain only.
Master Control: If the drive is set to Master Control (RPL = 11b), it
generates the MASTER SYNC signal. This output is used by the
controller to generate the SLAVE SYNC signal for the slaves. Signal
termination is placed on the SLAVE SYNC signal at the first and the
last device in the chain only.
MICROPOL. AV LT
What is an AV Drive?
--------------------
Today's demanding digital video and audio applications require disk
drives to sustain a pre-determined minimum data transfer rate.
Any interruptions in this data rate are detrimental to AV
applications that require constant delivery of data at 30 frames per
second minimum. In standard drives utilized for data processing
requirements, the error correction and thermal calibration methods
employed are not optimized for continuous delivery of data. These
routine housekeeping tasks will procedure gaps in the data stream as
long as 850 ms, resulting in jumps, gaps, and stutters in motion and
sound when used in most AV applications.

==========================================
Daisy Chain Option Kit
----------------------
The MICRODISK AV LT subsystem will normally be last SCSI device on
the daisy chain. However, if you wish to daisy chain your MICRODISK
AV LT subsystem to other SCSI devices, you will need one Daisy Chain
Option Kit. This kit includes one each of the following items:
- SCSI System Cable (right angle connector)
- Daisy Chain (DCO) SCSI Backplane Cable
- MHA Rear Cover
Two SCSI system cables are available. Both cables have a Centronics
50-pin connector at the MICRODISK AV LT end, and either a Centronics
50-pin or mini-SCSI connector at the other end.
NOTE
Connect the SCSI system cable's right angle connector to the back of
the module.
Using the Daisy Chain Option Kit
--------------------------------
The MICRODISK AV LT subsystem will normally be the last SCSI device
on the daisy chain. However, if you wish to daisy chain your MICRO-
DISK AV LT subsystem to other SCSI devices, you will need one Daisy
Chain Option Kit.
To allow your MICRODISK AV LT subsystem to daisy chain to other SCSI
devices, you will remove the SCSI Backplane Cable from a MICRODISK AV
LT module (usually the TOP module in the stack), and replace it with
a Daisy Chain SCSI Backplane Cable. You will then install the MHA
rear cover, and connect the rightangle connector end of the SCSI
system cable to the Daisy Chain SCSI Backplane Cable connector, and
the other end (50-pin Centronics connector) to another SCSI device
outside the MICRODISK AV LT subsystem.

==========================================
Cables/Cords
------------
MICRODISK AV LT SCSI cables and AC power cords are manufactured to
the industry standard for this type of application. MICRODISK AV LT
module interconnect cables and cords have specific design features to
maintain both aesthetics and uncompromising performance.
Failure of any single power cord or SCSI cable will not cause data to
be lost. Failure of a single cord or cable may sometimes cause all
disk drive access to cease, but should never cause data stored on a
MICRODISK AV LT drive to be lost.
Getting Started
---------------
There are several kits that may be shipped for assembly and installa-
tion of a MICRODISK AV LT subsystem. The minimum MICRODISK AV LT
subsystem requires at least:
- One MICRODISK AV LT Module Kit.
- One MICRODISK AV LT System Configuration Kit.
- One SCSI/Power Cable Kit.
- One SCSI host adapter.
Depending on the configuration you may also need:
- Additional SCSI host adapters. - One or more MICRODISK AV LT Module Kit(s). - One or Expansion Kit(s). - One or more MICRODISK AV LT Multiple Host Adapter (MHA) Option Kit(s) . - One or more MICRODISK AV LT Daisy Chain Option Kit(s).
CAUTION
Do not twist cable or cord connectors during unpacking or assembly;
damage may occur.
MICRODISK AV LT Module Kit
--------------------------
A MICRODISK AV LT Module Kit includes one each of the following
items:
- MICRODISK AV LT Module
- Front Cover
- Rear Cover
- Hardware Registration Card
- Read First Document
To increase available storage capacity, modules may be assembled in a
"stack".
If you use more than nine modules in your MICRODISK AV LT subsystem,
new stacks should be created to accommodate the additional modules.
NOTE
The maximum recommended number of modules in each stack is nine.
Only seven SCSI devices can be connected to a single host adapter
If you have more than seven modules in your stack, you must install a
second host adapter and use a Multiple Host Adapter (MHA) Option Kit.
If you create more than one stack, you will need one Expansion Kit
and one SCSI/Power Cable Kit for each additional stack you create.
System Configuration Kit
------------------------
MICRODISK AV LT subsystems are assembled with the components included
in the MICRODISK AV LT System Configuration Kit, Module Kit(s), and
SCSI/Power Cable Kits. One System Configuration Kit is required per
MICRODISK AV LT subsystem.
The MICRODISK AV LT System Configuration Kit includes one each of the
following items:
- Top Cover
- SCSI Terminator
- Base Assembly (with Power Switch)
- Read First Document
- Assembly and Installation Guide.
SCSI/Power Cable Kit
--------------------
One SCSI/Power Cable Kit is needed per stack. There are six types of
cable kits to address the Centronics SCSI Connector (ISA) or mini-
SCSI Connector (EISA/MCA) and three types of AC Power Cords
available: U.S., U.K., or European:
- U.S. Standard SCSI/Power Cable Kit
- U.S. Mini-SCSI/Power Cable Kit
- U.K. Standard SCSI/Power Cable Kit
- U.K. Mini-SCSI/Power Cable Kit
- European Standard SCSI/Power Cable Kit
- European Mini-SCSI/Power Cable Kit
Each type of SCSI/Power Cable Kit includes one each of the following
items:
- SCSI System Cable (Centronics SCSI)
- AC Power Cord
Expansion Kit
-------------
One Expansion Kit is necessary for every new stack you create.
An Expansion Kit includes one each of the following items:
- Top Cover
- SCSI Terminator
- Base Assembly (with Power Switch)
Multiple Host Adapter Option Kit
--------------------------------
One MHA Option Kit, required for each additional host adapter used
in any single stack, includes one each of the following items:
- SCSI System Cable (right angle connector)
- MHA SCSI Backplane Cable
- SCSI Terminator
- MHA Rear Cover
Two SCSI system cables are available. Both cables have a Centronics
50-pin connector at the MICRODISK AV LT end, and either a Centronics
50-pin, mini-SCSI, or mini-SCSI connector at the host adapter end.
NOTE
Connect the SCSI system cable's right angle connector to the back of
the module.
Compatible SCSI Host Adapters ----------------------------- Your computer needs at least one SCSI host adapter in order to communicate with modules in a MICRODISK AV LT subsystem. If you need a SCSI host adapter or have any questions, please contact your dealer.

* These host adapters do not accept the standard 50-pin SCSI connector cable. Please contact your reseller to obtain the appropriate cable if you have one of these host adapters.
Host Adapter Considerations --------------------------- - One MHA Option Kit is required for each additional host adapter you add to an existing stack.
- When installing host adapters, ensure that there are no port address or IRQ conflicts with other cards already installed or planned for installation. Refer to your host adapter documentation for specific details.
MICRODISK AV LT Assembly
------------------------
A MICRODISK AV LT subsystem may be as small as one module, or you can
add modules to increase storage capacity and create multiple stacks
if you so desire.
The minimum MICRODISK AV LT configuration requires on MICRODISK AV LT
Module Kit, one System Configuration Kit, one SCSI cable, one power
cord, and one SCSI host adapter.
Terminator
----------
The terminator must installed in the last module in the chain for
each SCSI bus (Host Adapter).
MICRODISK AV LT Series Disk Drives
----------------------------------
Each module in a MICRODISK AV LT subsystem contains a MICRODISK AV LT
Series disk drive. MICRODISK AV LT Series disk drives are engineered
specifically for multimediam high-end graphics, and digital audio/
video applications.
MICRODISK AV LT Series disk drives have the highest minimum sustained
data rate in the industry in their class at 3.0 MB/sec, and a maximum
sustained uninterrupted data rate of 2.9 MB/sec. Industry standard
high capacity data processing drives are not designed for high
sustained, uninterrupted data rates - factors which are required for
real-time recording and playback of digital audio/video data.
Standard drives perform short, random "burst" transfers, leaving gaps
in the data stream.
MICRODISK AV LT Formatting/Partitioning
---------------------------------------
Your MICRODISK AV LT subsystem modules need to be formatted and
partitioned before they can be used for data storage. To perform
these functions, use the disk formatting/partitioning utility
program(s) that you received as part of your operating system
software.
The utilities prepare your MICRODISK AV LT modules for use. Under
normal circumstances you will only need to format and partition each
MICRODISK AV LT module once.
NOTE
Because each module in a MICRODISK AV LT stack is a separate,
independent SCSI device, you must format and partition each MICRODISK
AV LT module separately.
Formatting the Hard Disk
------------------------
Formatting lays down distinct patterns on the disk which set up the
disk's organizational structure. You normally need to format the disk
only once.
Installing Partitions
---------------------
Partitioning prepares a hard disk for use by the PC. Partitions allow
you to divide the space available on the hard disk into separate
areas which appear on the desktop as separate logical disk drives
(volumes). This allows more flexible management of files (i.e., you
can use one partition for word processing, another for database work,
etc.).
Management of back-up also becomes easier with a wellorganized and
partitioned hard disk. A large hard disk with many small files takes
up a lot of disk space because of the way the filing system allocates
disk space. You can save space by partitioning the hard disk into
smaller volumes.
Carefully plan your partitions, as you cannot change partitions with-
out erasing your data. If you choose to alter the sizes or types of
partitions, you should:
1. Back up all your files
2. Make partitioning changes
3. Restore the files to their new volumes.
CAUTION
Remember, you can change partitions later, but all the information
stored on them will be lost. Make sure you have all data from these
partitions backed-up before changing the partitions.
It is not necessary to reformat the disk to redefine the partitions.
MICRODISK AV LT Operation
-------------------------
The MICRODISK AV LT subsystem MUST be turned on prior to, or at the
same time as, your computer.
The MICRODISK AV LT subsystem MUST be turned on whenever your
computer is on.
