The Wangdat 3200 is a DDS1 drive with a 2/4Gb capacity. It is 3.5" as standard, a 5.25" fixing kit and bezel is available as an option.
INTRODUCTION
The following tables and notes give a quick guide in setting up the Wangdat 3200 2/4Gb.
The notes explain the setting of dip switch block SW1, dip switch block SW4, jumper JP1
and the three terminating resistors.
| SW1 - Dip Switches | On Value | Off Value | Default Settings |
| 1 | Enables Buffered Mode | Disables Buffered.Mode | OFF |
| 2 | Compression ON = 4Gb | Compression OFF = 2Gb | ON |
| 3 | SCSI 2 | SCSI 1 | ON |
| 4 | Enables Cartridge Eject | Disables Cartridge Eject | OFF |
| 5-8 | Reserved | Reserved | OFF |
| SW4 - Dip Switches | On Value | Off Value | Default (Parity ON, SCSI ID 0) |
1 |
Parity is enabled | Parity is disabled | ON |
2 |
Gives SCSI ID Value of 1 | Gives SCSI ID Value of 0 | OFF |
3 |
Gives SCSI ID Value of 2 | Gives SCSI ID Value of 0 | OFF |
4 |
Gives SCSI ID Value of 4 | Gives SCSI ID Value of 0 | OFF |
NB.You can choose any SCSI ID value from 0 to 7. See table
below.
To do this the dip switches 2, 3 and 4 from SW4 are arranged in various ON OFF
combinations.
So for example SCSI ID 5 would be ON OFF ON (1 + 0 + 4 = 5).
| SW4 - Dip Switches | Dip Switch 2 (Value = 1) | Dip Switch 3 (Value = 2) | Dip Switch 4 (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: JP1 (Jumper Block)
Jumper JP1 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 Wangdat 3200 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.
| LED/Colour | State | Indication |
| Green (left LED) | On | Drive activity on SCSI bus |
| Red (left LED) | Flashing | Drive fault condition exists |
| Amber (right LED) | Flashing | Unloading/Loading cartridge |
| Amber (right LED) | On | Cartridge in place, compression disabled (2Gb) |
| Green (right LED) | On | Cartridge in place, compression enabled (4Gb) |
The table of LED indicators on the left, gives an idea of the various functions of the flashing LEDs.
JUMPER BLOCKS INSTEAD OF DIP SWITCHES
There are versions of the Wangdat 3200 2/4Gb that have jumper blocks instead of dip
switches. However the jumper block pin pairs control the same function as their respective
dip switch number. On a Wangdat 3200 with jumpers, the SW1 switch block is labelled JP2,
and the SW4 switch block is labelled JP3.
So for example.
On a 3200 with dip switches, the SW4 dip switch 1 controls whether parity is enabled or
not.
On a 3200 with jumpers, the JP3 jumper block pin pair 1 controls the parity.
etc
| Media | 60 Metre |
90 Metre |
To back up 4Gb (compression ON) on a Wangdat 3200 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 |
