The Archive 4326 is a DDS2 DAT drive with a 4/8Gb capacity, achievable through hardware compression. The drive is 3.5" sized as standard (product code 4326NP), and a 5.25" fixing kit and bezel is available as an option (product code 4326RP).

INTRODUCTION
The following tables and notes give a quick guide in setting up the Archive 4326 4/8Gb.
The notes explain the setting of dip switch SW1, JP4 jumper, JP6 six pin block and the two terminating resistors.

Archive 4326 4/8Gb DAT - SW1 Switch Settings
Dip Switch Number On Value = Off Value = Default Settings
1 SCSI ID=1 SCSI ID=0

2 SCSI ID=2 SCSI ID=0

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).

Archive 4326 4/8Gb DAT - SCSI ID Further Explanation
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 4326 4/8Gb 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 4326 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 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.

90 Metre

120 Metre To back up 8Gb (compression ON) on an Archive 4326 a 120 metre cartridge is used, if compression was OFF a 4Gb capacity would be acheived.  Inserting a 90 metre cartridge gives a 4Gb compressed and 2Gb native capacity.  Inserting a 60 metre cartridge gives a 2.6Gb compressed and 1.3Gb native capacity.
