A Wangdat 3800 is an internal DDS2 DAT drive with a 4/8Gb capacity. It is 3.5" sized as standard, a 5.25" fixing kit and bezel is available as an option. The Wangdat 3800SE (the external version) is also available.
INTRODUCTION
The following tables and notes give a quick guide in setting up the Wangdat 3800 4/8Gb.
The Wangdat 3800 has the same capacity as a Wangdat 3400 - 4/8Gb - but it is a much
quicker drive
The notes explain the setting of the 16 pin jumper block.
| Jumper Block | Jumpered Value | No Jumper Value | Default Settings |
| Pin Pair 1 & 2 | SCSI ID 4 | SCSI ID 0 | No Jumper |
| Pin Pair 3 & 4 | SCSI ID 2 | SCSI ID 0 | No Jumper |
| Pin pair 5 & 6 | SCSI ID 1 | SCSI ID 0 | No Jumper |
| Pin Pair 7 & 8 | Compression Disabled = 12Gb | Compression Enabled = 24Gb | No Jumper |
| Pin Pair 9 &10 | Enables SCSI Parity | Disables SCSI Parity | Jumpered |
| Pin Pair 11&12 | Factory Use Only - Do not jumper | Factory Use Only - Do not jumper | No Jumper |
| Pin Pair 13 &14* | Terminates the drive | No.termination | Jumpered |
| Pin Pair 15 &16** | SCSI bus Termination Power | No termination power | Jumpered |
NB.You can choose any SCSI ID value from 0 to 7. See table
below.
To do this the pin pairs 1&2, 3&4 and 5&6 from the 16 pin jumper block
are arranged in various ON OFF combinations.
So for example SCSI ID 5 would be ON OFF ON (4 + 0 +1 = 5).
| Jumper Block | Pin Pair 1 & 2 (Value = 4) | Pin Pair 3 & 4 (Value = 2) | Pin Pair 5 & 6 (Value = 1) |
| SCSI ID VALUE 0 | OFF (No Jumper) | OFF (No Jumper) | OFF (No Jumper) |
| SCSI ID VALUE 1 | OFF (No Jumper) | OFF (No Jumper) | ON (Jumpered) |
| SCSI ID VALUE 2 | OFF (No Jumper) | ON (Jumpered) | OFF (No Jumper) |
| SCSI ID VALUE 3 | OFF (No Jumper) | ON (Jumpered) | ON (Jumpered) |
| SCSI ID VALUE 4 | ON (Jumpered) | OFF (No Jumper) | OFF (No Jumper) |
| SCSI ID VALUE 5 | ON (Jumpered) | OFF (No Jumper) | ON (Jumpered) |
| SCSI ID VALUE 6 | ON (Jumpered) | ON (Jumpered) | OFF (No Jumper) |
| SCSI ID VALUE 7 | ON (Jumpered) | ON (Jumpered) | ON (Jumpered) |
SCSI TERMINATION
*Termination - The pin pair 13&14
controls drive termination. The Wangdat 3800 must be terminated, by jumpering pin
pair13&14, if it is either a stand alone unit, or last in a chain of devices. (The
default setting is for the pins to be jumpered).
**SCSI Bus Termination Power - The pin pair 15 & 16 controls the drive's termination power, a
jumper on this pin pair connects termination power to the SCSI bus. When jumpered
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).
SCSI CONNECTION
The Wangdat 3800 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.
| LED | State | Indication |
| Drive Status (Left) |
OFF | No drive activity on the SCSI bus. |
| ON | Drive activity on the SCSI bus. | |
| FLASHING | Drive moving tape. | |
| Tape Cartridge Status (Center) |
OFF | No tape cartridge in drive. |
| ON | Tape cartridge in drive. | |
| FLASHING | Tape cartridge loading or unloading. | |
| Attention (Right) |
OFF | Drive O.K. |
| ON | Cleaning required. | |
| FLASHING | Tape cartridge high soft error rate (clean drive or replace cartridge). | |
| DOUBLE FLASHING |
Self test failure. |
| Media | 60 Metre |
90 Metre |
120 Metre | To back up 8Gb (compression ON) on a Wangdat 3800 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. |
| Native | 1.3Gb |
2Gb |
4Gb | |
| Compressed | 2.6Gb |
4Gb |
8Gb |
