Chapter 1  Installing the ValueLoader
Understanding ValueLoader Features
ValueLoader DLT VS80/DLT VS160 Tape Autoloader User Manual
3
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.
Bar Code Reader
1
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 
Re-inventory
 command is issued 
 on page 32). Beyond that, there 
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 
www.Quantum.com
 for information on obtaining additional bar code 
labels.
SCSI 
Requirements
1
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.
