The Archive 4322 is a DDS 1 drive with a 2/4Gb capacity, achievable through hardware compression. The drive is 3.5" sized as standard (product 4322NP), a 5.25" fixing kit and bezel is available as an option (product 4322RP).
INTRODUCTION
The following tables and notes give a quick guide in setting up the Archive 4322
2/4Gb.
The notes explain the setting of dip switch SW1, JP4 jumper, JP6 six pin block and the two
terminating resistors.
Dip Switch Number | On Value = | Off Value = | Default Settings |
1 | Sets SCSI ID Value of 1 | Sets SCSI ID Value of 0 | OFF |
2 | Sets SCSI ID Value of 2 | Sets SCSI ID Value of 0 | OFF |
3 | Sets SCSI ID Value of 4 | Sets SCSI ID Value of 0 | OFF |
4 | SCSI 2 | SCSI 1 | ON |
5 | Enables Parity | Disables Parity | OFF |
6: DDS Pass Through | ON=DDS 2Gb | OFF=DDSDC (Data Compression) 4Gb | OFF |
7 | Reserved | Reserved | Reserved |
8 | Self Test | Self Test | Self Test |
NB. You can choose any SCSI ID value from 0 to 7. See table
below.
To do this the dip switches 1, 2 and 3 from SW1 are arranged in various ON OFF
combinations.
So for example SCSI ID 5 would be ON OFF ON (1 + 0 + 4 = 5).
SW1 - Dip Switches | Dip Switch 1 (Value = 1) | Dip Switch 2 (Value = 2) | Dip Switch 3 (Value = 4) |
SCSI ID VALUE 0 | OFF | OFF | OFF |
SCSI ID VALUE 1 | ON | OFF | OFF |
SCSI ID VALUE 2 | OFF | ON | OFF |
SCSI ID VALUE 3 | ON | ON | OFF |
SCSI ID VALUE 4 | OFF | OFF | ON |
SCSI ID VALUE 5 | ON | OFF | ON |
SCSI ID VALUE 6 | OFF | ON | ON |
SCSI ID VALUE 7 | ON | ON | ON |
SCSI TERMINATION: JP4 (Jumper Block)
Jumper JP4 connects termination power to the SCSI bus. When the two pins are jumpered, and thus installed,
termination power is supplied by the drive. Without a jumper the power is supplied by the
host. (The default setting is for the pins to be jumpered).
Terminating Resistors - The drive must be
terminated (using the terminating resistors) if it is either, a stand alone unit, or last
in a chain of devices. Terminating resistors are fitted one way only, a white circle
printed on the PCB shows pin1.
SCSI CONNECTION
The Archive 4322 2/4Gb needs to be connected to a SCSI controller card. A low cost card,
such as an Adaptec 1505, is
suitable for this task. However the Adaptec 1505 will only control the one SCSI
device.
EXTERNAL SCSI ID SELECTION : JP6 (Jumper Block)
JP6 is the SCSI ID selector if used in an external case. If the Archive 4322 is to be used
in an external cabinet the SCSI ID dip switch selectors (1, 2, and 3) on SW 1 should all
be set to OFF.
LED/Colour | State | Indication |
Yellow | On | Drive is reading or writing to the tape |
Yellow | Flash Rapidly | Hardware fault, or dew detected. |
Green | On | Cartridge is inserted, no excess errors |
Green | Flash Slow | Cartridge is inserted, excessive errors. Use a DDS cleaning tape. |
Green | Flash Slow + Yellow Flashing | A pre-recorded audio cartridge is inserted and is being played automatically. |
Green | Flash Rapidly | Drive can't read or write to the tape correctly. Try using a DDS DAT cleaning tape. |
Media | 60 Metre |
90 Metre |
To back up 4Gb (compression ON) on an Archive 4322 a 90 metre cartridge is used, if compression was OFF a 2Gb capacity would be acheived. Inserting a 60 metre cartridge gives a 2.6Gb compressed and 1.3Gb native capacity. |
Native | 1.3Gb |
2Gb |
|
Compressed | 2.6Gb |
4Gb |
