Unpacking / Packing
(1) General precautions
Note the following precautions in order to maintain the
performance and reliability of the drive.
! Open the package with particular care.
! Do not expose the unit to excessively dusty environment.
! The unit contains components that can be destroyed by static
electricity.
Follow the guidelines below for internal unit:
! Use an anti-static mat and ground yourself when handling the
internal unit.
! Always be sure to handle the internal unit only by the frame and
do not touch any electrical components.
(2) Unpacking (Internal Unit)
When moving the unit to an environment where there is a
significant difference in temperature, let the unit remain in its
packaging for at least two hours.
Find a flat, soft surface for unpacking, keeping the box upright.
Do not apply excessive force to the unit when removing the shock-
absorbing material, or to the surfaces and interface connector
when removing the anti-static bag.
(3) Unpacking (External Unit)
When moving the unit to an environment where there is a
significant difference in temperature, let the unit remain in its
packaging for at least two hours.
Find a flat, soft surface for unpacking, keeping the box upright.
MOD520 manual revise 14/5/98 10:32 am Page iv

(4) Packing
Pack the unit after you have removed the disk.
Put the device in the anti-static or plastic bag.
It is desirable to use the original shock-absorbing material and
packing box used when the unit was delivered to you. If not, use
a box with a shock-absorbing structure that will prevent direct
impacts to the device. In the case of the internal unit, protect
the surfaces and interface connector against possible damage and
use an anti-static bag.
(5) Transportation
!Transport the unit in a well-packaged condition, with the upside
facing up.
! Transport the unit as little as possible after unpacking, always
using the shock absorbing material to avoid impact and vibration.
When carrying the unit after unpacking, keep it in the horizontal
plane.
(6) Storage
• Use the moisture-proof packing material for storage.
• The storage environment should meet the non-operating
environmental requirement as specified in Appendix E.
! Do not expose the unit to radical changes in temperature, which
could cause condensation.

WORM disks.
✓Half height unit.
✓Reads 594MB and 650MB disks as well as 1.2GB, 1.3GB, 2.3GB
and 2.6GB media as used in earlier MO drives in addition to
read & write compatibility to 2.3GB and 2.6GB disks.
✓Data cache of 4MB for write and read operations.
✓Effective seek time of 25ms

SCSI Connections
The external drive is equipped with two Micro D 50 way connectors
on the rear panel. These are for the SCSI in and SCSI out (if there
are additional devices connected).
A SCSI interface cable needs to be terminated at each end of the
line, one terminator being on the last device in the chain and the
other terminator is usually on the host computer or adapter card,
a Micro D SCSI Terminator is supplied (external drive only).
Refer to the documentation supplied with your SCSI card or
computer system should you need to check the computer
termination. In normal circumstances this will usually be enabled.
The two ways of connecting SCSI devices are shown below :
Fig 1.External Drive Connection
Fig 2.Internal Drive Connection

1.Switch block SCSI ID setting
2.SCSI connector for additional devices or terminator if last in chain.
3.SCSI cable
If there are also internal devices on the same SCSI card, then the
SCSI adapter card must have its on-board termination disabled.

SCSI Identifier
Each device on a SCSI bus requires a unique address to be set which
maybe in the range of 0 to 6 as address 7 is usually reserved for the
host computer address. The MOD520 is shipped with a default
address of 1 which will usually suffice in most cases.

General Precautions for MOD520E
✗Never plug or un-plug any connectors or cables from the
device on the SCSI bus whilst power is applied to either host
computer or any devices attached.
✗Do not use the unit under the following operating
environments :
Places with high humidity
Exposed to direct sunlight
Locations subject to excessive shock or vibration
✗Do not cover ventilation slots as these are provided for cooling.
✗Do not place the drive near a printer.
✗Never attempt to disassemble the unit.
✗Never touch the surface of a recordable disk.
✗Do not allow any foreign object or liquid to enter the unit.
✓Always remove the disk before moving the unit. This will
ensure that the optical head is securely positioned for shipping.
✓Keep the packaging material should the unit have to be
transported.
Additional Notes for Internal Models
✗Never connect / disconnect unit to / from SCSI bus with
power on any units including host computer.
✓When handling the unit, an anti-static wrist strap should be
used to avoid possible damage from static electricity.
✓Ensure that the power connector is correctly wired.
✓Check that the power is within the unit’s specification.
✓Ensure that adequate ventilation is provided.

GETTING STARTED
Operation & Installation Instructions
External Drive
Do not apply power yet!
Set the SCSI ID of the unit via the DIP switch on the rear of the
unit.
Connect the SCSI interface cable between the computer and the
drive unit.
If the drive is the last unit on the SCSI interface, install the
supplied terminator in the unused SCSI connector.
Apply power to the unit.
Insert a disk cartridge into the drive, gently pushing it into the
drive until it is power loaded. The motor will start and after a few
seconds the drive will be ready for use.
When the eject button is pressed the cartridge will electronically
eject from the drive after a short delay.
Notes:
If you need to use the emergency eject pinhole, make sure that
the unit is powered off and that the disk has stopped its rotation
(20-30 seconds after power off).
If the SCSI ID is changed with the unit powered ON, then power
must be removed and reapplied for the new ID to take effect.
Before moving the drive, always ensure that the optical disk
cartridge is removed.
The drive has various functions that may be altered from their
defaults if required. These are outlined in the MOD520I section.
Opening the enclosure and changing these settings must only be
carried out by a qualified service engineer.

Internal Drive
! The drive must only be used in the horizontal plane.
• Attaching screws are supplied with the unit. The screws are M3 x
4 mm, and the fixing plate should be within the range of 1.5 to
2.5 mm, which includes the washer.
• Included with internal drives is a 50-way flat IDC cable with 2
connectors for connection to the SCSI adapter.
Note for correct orientation of the flat cable when installing! Pin 1 is
usually identified by a red stripe on the edge of the cable, and
connectors have a small arrow by pin 1.
! Connect the internal power connector in your computer to the
drive making sure that the orientation is correct.

Placing a service call
Contact your supplier or service company. They will probably require
the following information;
Where purchased
Date of Purchase
Serial Number
Description of failure
System information which may include;
?Computer type and SCSI adapter type

Service on the unit
There is no prescribed service for the unit. However, to ensure
optimum performance, the unit should operate in as clean an
environment as possible where contaminants do not enter the unit.
Should the unit require cleaning, do NOT attempt to open the drive,
but contact your supplier.
Microsoft Operating Systems and Optical support
Microsoft have confirmed that their NT operating system versions
3.51 and 4.0 do not currently FULLYsupport any WORM or Rewritable
Optical media (512,1024 or 2048 bytes per sector) or drives under
Fat or NTFS File Systems.
NT using FAT or NTFS, only supports Optical if the drive and media act
as a Magnetic Hard Drive. (Type 0 Device)
Windows NT will support both WORM and Rewritable Optical media
when used with another File System (such as Plasmon Drive Manager
for NT).
FAT and NTFS with full Optical support are being looked into for a
future release of NT from Microsoft.
Microsoft have committed that Windows 95 will read and write
Rewritable Optical media only when it has been formatted with
third party software. WORM media is not supported and requires
third party software.
Customers using NT with Plasmon Multitasking Manager have no
needfor any action.
For details of Optical support in future products from Microsoft,
please contact them direct.
