INTRODUCTION
The Conner CTD8000 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 following tables and notes give a quick guide in setting up the Conner CTD8000 4/8Gb.
CONFIGURING YOUR TAPE DRIVE
Locate the dip-switches by turning the tape drive upside down with the front bezel facing
towards you. The dip-switchbank is positioned on the right hand side of the tape
drive. If you find that your tape drive doesn't have a dip-switchbank, please click here.
The Conner CTD8000 is despatched with factory default settings, as shown in the table
below.
You should find that only the SCSI ID needs to be altered to suit your system (read below
for full SCSI ID variations and instructions on achieving them).
Once this as been completed, the drive may need to be terminated (depending on your
system), see SCSI TERMINATION below.

Switch 4 (MRS MODE) If ON the drive reads or writes both MRS and non-MRS 4mm media. if OFF, the drive reads and writes to MRS media and reads from but does not write to 4mm media.) Switches 1-3 (SCSI ID) The three switches correspond to the SCSI ID. Each SCSI device on a bus must have a unique SCSI ID. The highlighted example shows SCSI ID 5. ON OFF ON (4 + 0 + 1 = 5) |

SCSI TERMINATION
If you're unsure whether you need to terminate your tape drive, refer to the SCSI termination page
To set the SCSI termination and SCSI power on a Conner CTD8000 tape drive, you must look
to the rear of the drive. There you will see, above the SCSI interface and power
connection, a 16 pin jumper block. Ensure that only pins 11 and 12 (SCSI
TERMINATION) and pins 15 and 16 (SCSI TERMINATION POWER) are jumpered. The diagrams
below show both the position of the jumper block and the jumper block in greater detail.

SCSI CONNECTION
The Conner CTD8000 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 Colour | State | Indication |
| Yellow (Left) | ON (lit) | The drive is reading or writing the tape. |
| Yellow (Left) | Flashing Rapidly | A hardware fault occurred. |
| Green (Right) | ON (lit) | A cartridge is inserted and does not generate excessive errors. |
| Green (Right) | Flashing Slowly | A cartridge is inserted but generates
excessive errors beyond a predefined error threshold. (Warning only). Use a DDS DAT cleaning cartridge to clean the heads. |
| Green (Right) | Flashing Slowly (with yellow LED flashing) |
A pre-recorded audio cartridge is inserted and is being played automatically. |
| Green (Right) | Flashing Rapidly | The drive could not write the tape
correctly. (ERROR). Use a DDS DAT cleaning cartridge to clean the heads. |
60 Metre |
90 Metre |
120 Metre | To back up 8Gb (compression ON) on a
Conner CTD8000 a 120 metre cartridge is used, if compression was OFF a 4Gb capacity would
be achieved. 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. (*assumes 2:1 compression ratio) |

Routine Maintenance
If excessive magnetic dust or debris collects at one or more of the tape heads, your drive
may not be able to read from or write to tape. To avoid this situation, you must
clean the tape heads on your DAT drive in the following circumstances:
After the first four
hours of tape movement of a new cartridge
After every 25 hours
of read/write operation.
Whenever the
rectangular, green cartridge-status LED flashes during operation.
Note. A slowly flashing green LED may indicate that a tape is damaged or is nearing the end of it's life. if cleaning the head does not correct the flashing LED condition, replace the cartridge. the slowly flashing LED does not indicate a loss of data, nor does it, indicate SCSI problems.
To clean the tape heads on your drive, use a DDS DAT
cleaning cartridge. After you insert the cartridge, the drive detects that the
cartridge is a cleaning cartridge, then loads and runs the cartridge for about 30 seconds.
When cleaning is complete, the drive ejects the cartridge.
Each time the cleaning cartridge is loaded, a new, unused portion of cleaning tape is
advanced over the entire tape path. The drive does not rewind a cleaning cartridge.
After about 30 cleaning cycles, the entire tape is used, and you must purchase a
new cleaning cartridge.
If you insert a cleaning tape that has been used up, the drive ejects the tape without
completing a cleaning operation. this process takes just under 25 seconds.
