Description
NOTE
The maximum time to back up (read or write) on a TLZ09/9L cassette tape
in a continual (streaming) mode is system dependent. The efficient use of
streaming mode is determined by your operating system. Please refer to your
system software documentation.
As of this printing, the TLZ09/9L device is supported by a variety of Digital
systems. Consult your Digital Sales Support representative for a list of
supported systems. Your particular system must have an available standard
SCSI (Small Computer System Interconnect) port in order to connect the
TLZ09 or TLZ9L.
1.2 Design Features
The TLZ09/9L cassette tape device uses state of the art technology. The
device’s design incorporates the Digital Data Storage (DDS) recording format
and Digital Audio Tape (DAT) recording technologies. It is also designed to
provide a transfer rate that is twice that of standard DDS-2 DAT drives while
still maintaining full DDS compatibility.
1.2.1 What is Digital Audio Tape (DAT)?
DAT technology provides a high recording density with a very low error rate
through the helical scan recording method. With this method of recording,
both the tape and the recording head move simultaneously. The read and write
heads are located on a rapidly rotating cylinder, or drum that is tilted at an
angle in relation to the vertical axis of the tape. This causes the tracks to be
recorded diagonally across the tape, resulting in an extremely high recording
density, far higher than what is achievable with stationary-head devices.
1.2.2 What is Digital Data Storage (DDS)?
DDS uses a recording format that supports the use of digital audio tape
for computer applications. The objectives of DDS are to maximize storage
capacity and performance, facilitate data interchange, and provide very fast
random access. In addition, this format has three levels of error correction,
which ensures high data integrity. The DDS-DC format, which is a superset
of the basic DDS DAT format, allows you to back up 8 gigabytes of data in
approximately 1.5 hours minimum with no operator intervention, assuming 2:1
compression ratio.
Use of non-DDS media may result in degraded drive performance and
is not recommended by Digital Equipment Corporation.
MRS refers to a series of alternate opaque and clear stripes at the beginning
of a tape. This striping is used to classify the media as data grade rather than
audio grade media. Use of MRS helps to ensure that only data grade tapes are
used in computer applications. All 120-meter cartridges support MRS. Shorter
media are available in both MRS and non-MRS types.

2. Halt the system.
3. Set all system power switches off.
Installing the Tabletop Drive or Autoloader (TLZ09-DA/DB or TLZ9L-DA/DB) 2–1
2.3 Selecting the SCSI Address
To familiarize yourself with the TLZ09 drive and TLZ9L autoloader:
1. Refer to Figure 1–1 for the location of the buttons, switches, and connectors
on the tabletop drive and to Figure 7–2 for the location of the buttons,
switches, and connectors on the tabletop autoloader.
2. Note that all connections are made at the rear of the tabletop enclosure.
Your system uses a SCSI ID switch to identify, or address, the drive. The SCSI
ID is factory set at 0. If you are installing the drive on a system that is already
using SCSI ID 0, use any available SCSI ID. (You may have to consult your
system manager.)
To set/change the SCSI address:
1. Locate the SCSI address switch at the rear of the tabletop enclosure.
2. Select the SCSI address for the drive or autoloader. Press the + or button until the desired address (0 through 7) appears in the window. See
Figure 1–1 for the drive and Figure 7–2 for the autoloader.
If you are installing any other drive variant, refer to Chapter 3.
Turn off all power before connecting the cables and the terminator.
The drive must be turned off and then on for switch settings to take
effect, or a SCSI bus reset must be received.
NOTE
2–2 Installing the Tabletop Drive or Autoloader (TLZ09-DA/DB or TLZ9L-DA/DB)
The tabletop devices provide two SCSI connectors to allow daisy chaining.
Either connector can connect to the host computer or any SCSI device in a
daisy chain.
•If the tabletop is the last device in the chain an interface cable is attached
to one connector and an active SCSI terminator is installed in the other
connector.
•If the device is within the chain, the interface cable from the preceding
device is connected in one connector; an interface cable is also connected
from the other connector to the following device.
NOTE
Make sure that the last SCSI device on the bus is terminated correctly
and is jumpered to supply termination power
2.4 Connecting a SCSI Signal Cable — Device to System
If you are connecting a TLZ09-DA/DB drive or TLZ9L-DA/DB
autoloader directly to your system, you should use the SCSI signal
cable supplied as part of your system installation kit.
If you do not have this cable, contact your Digital sales representative. You
should use a cable supplied by Digital Equipment Corporation. Failure to do
so can result in degraded performance of your tabletop device.
To connect a SCSI cable — device to system — perform the following:
1. Connect one end of the cable to the system SCSI connector.
2. Connect the other end of the SCSI signal cable to either SCSI connector on
the rear of the TLZ09-DA/DB drive or TLZ9L-DA/DB autoloader.
3. Secure the SCSI cable by snapping the wire cable clamps (on either side of
the SCSI connector) into place.
4. Connect the SCSI terminator to the other SCSI connector on the rear of
the TLZ09-DA/DB drive or TLZ9L-DA/DB autoloader.
5. Secure the terminator by snapping the wire cable clamps (on either side of
the SCSI connector) into place.

2.5 Adding Another Tabletop Device — Device to Device
If you have one SCSI tabletop device already connected to your system, you
can connect the TLZ09-DA/DB drive or the TLZ9L-DA/DB autoloader to that
device. For device to device connections, use a 50-pin low density to 50-pin low
density SCSI signal cable [PN 17-03926-02 (gray), 17-04370-01 (frost white), or
equivalent].
Care should be taken to ensure that total SCSI cable length is well within the
SCSI specification limit of 6 meters for 5 MB/s transfer speeds (including cable
length within the system enclosure). When operating at FAST SCSI (10 MB/s)
transfer speeds, the total cable length must not exceed 3 meters. It is also
important to ensure that the drive is configured to supply terminator power to
the bus (default configuration). See Chapter 3 or Chapter 7 for jumper/switch
configurations.
1. If present, remove the SCSI terminator from the existing SCSI drive.
2. Connect one end of the SCSI signal cable (see part numbers above) to
the existing SCSI device, observing the correct orientation of the cable
connector.
3. Secure the SCSI cable by snapping the wire cable clamps (on either side of
the SCSI connector) into place.
4. Connect the other end of the SCSI signal cable to either SCSI connector on
the TLZ09-DA/DB drive or TLZ9L-DA/DB autoloader, observing the correct
orientation of the cable connector.
5. Secure the SCSI cable by snapping the wire cable clamps (on either side of
the SCSI connector) into place.
6. Connect the SCSI terminator to the other SCSI connector on the TLZ09DA/DB drive or TLZ9L-DA/DB autoloader, observing the correct orientation
of the cable connector.

2.6 Connecting the Power Cable
The tabletop devices have an autoranging power supply. Refer to Table A–1 or
Table A–4 for voltage specifications.
To connect the power cable, proceed as follows:
1. Be sure that the TLZ09-DA/DB drive or TLZ9L-DA/DB autoloader power
switch is off (0).
2. Connect the power cable to the TLZ09-DA/DB drive or TLZ9L-DA/DB
autoloader power connector.
3. Connect the other end of the power cable to a nearby ac outlet.
Multivendor Customer Services personnel: The power cable disconnects
the device from the main ac power source.

To familiarize yourself with the TLZ09 drive:
1. Refer to Figures 1–2 through 1–4 for the location of the buttons, switches,
and connectors on the TLZ09 drive.
2. Note that all connections are made at the rear of the drive.
3.3.1 SCSI ID Address Jumpers
Your system uses a SCSI ID jumper block to identify, or address, the TLZ09.
The SCSI ID is factory set at 0. If you are installing the TLZ09 on a system
that is already using SCSI ID 0, use any available SCSI ID. (You may have to
consult your system manager.)
To set/change the SCSI address, refer to Figure 1–2 and Figure 3–1 for jumper
block location, then:
1. Refer to Figure 3–1 for jumper configuration.
2. Select a unique address number with the first three jumpers on the left.
Table 3–1 shows the SCSI IDs (0 through 7) and Figure 3–1 shows a close-up
view of the jumpers.
NOTE
If you are installing the tabletop variant, refer to Chapter 2.
Turn off all power before connecting the cables.
The drive must be power cycled for switch settings to take effect, or a
SCSI bus reset must be received.
Make sure that both ends of the SCSI bus are terminated correctly. For
the drive, termination is enabled by installing a jumper on pins 13 and
14 of the jumper block.
