ValueLoader DLT VS80/DLT VS160 Tape Autoloader User Manual
The ValueLoader DLT VS160 uses up to eight DLT VS1 data cartridges,
providing a maximum formatted capacity of 1280 GB and a sustained
data transfer rate as high as 960 MB per minute, assuming a 2:1
compression ratio.
The ValueLoader is compatible with most operating systems and
environments that support the SCSI interface, but requires either direct
support from the operating system or a compatible backup application to
take full advantage of its many features.
Your ValueLoader may have come equipped with an optional bar code
reader. The bar code reader is enclosed in a plastic housing that protrudes
out of the back panel of the ValueLoader, just above the SCSI connectors.
The bar code reader automatically scans each cartridge in the carousel
upon power up, after a reset, or when a
(see Creating an Inventory of Cartridges
is no user interface with the bar code reader via the front panel operator
controls or LCD screen. The information from each label is stored in
memory and available through SCSI to the computer's operating system
or backup application upon request.
If utilizing the bar code reader, you must insert a bar code label into the
slide-in slot on the front of each cartridge. These labels must conform to
ANSI/AIM BC1-1995, Uniform Symbology Specification Code 39. A set
of bar code labels is included with the ValueLoader. Refer to

labels.
The ValueLoader incorporates a wide SCSI-2, LVD SCSI bus. Make sure
your SCSI host adapter or controller supports these standards.
The ValueLoader can be attached to a single-ended (SE) SCSI bus, but this
is not recommended because it restricts performance. If you connect the
ValueLoader to an SE SCSI bus, or if there are SE devices attached to the
same SCSI bus, the autoloader's performance is limited to the maximum
data transfer speed and maximum cable lengths of the SE bus. The
ValueLoader is NOT compatible with a standard differential (Diff) or
high-voltage differential (HVD) SCSI bus. The ValueLoader can be
attached to a narrow (50-pin) SCSI bus using a customer-supplied 68-pin
to 50-pin adapter that terminates the unused 18 pins. These adapters are
sometimes labeled high-byte termination.
