Product Revision Level:
This field contains 4 bytes of ASCII data that provides the media changer's software revision
levels. When a firmware update is performed on the media changer, this part of the revision level
changes to reflect that update.
BarC: When set this bit indicates that the library is equipped with a bar code scanner.
IUS: Information Units Supported. Set to 0 indicating information units are not supported.
QAS: Quick Arbitrate Supported. Set to 0 indicating QAS is not supported.
Clocking:
Indicates the level of data clocking supported. Set to 11b if the host interface speed has not been
set to limit transfers to 80MB/s. Set to 00b when the host interface speed has been set to limit
transfers to 80 MB/s.
Version Descriptors:
The version descriptors report the identifier of the supported SCSI command sets.
