have been loaded. Sequential DLT1 is the same, except that the cartridges are
loaded into DLT1. Sequential Split mode provides two simultaneous
sequential modes. Cartridges 0 through 4 are loaded sequentially into DLT0;
cartridges 5 through 9 are loaded sequentially into DLT1.

Set Element Base: This setting allows you to set the base addresses of each of
the four SCSI elements of the module. In order to identify sources and
destinations in commands to the robotics, the Library System is divided into
elements, each of which is assigned a separate designator or element address.
The Transport Element is the robotics mechanism itself; the Storage Elements
are the slots in the magazines; the Transfer Elements are the drives, and the
Import/Export Element is the mail slot or slots. The Module reports these
settings in response to the SCSI Mode Sense command, in the Element
Address Assignment Page. The defaults are Transport element base = 0000,
Storage element base = 0001, Transfer element base = 00F0, and
Import/Export element base = 00E0.

Set Identification: This setting enables you to specify the response of the
Module’s robotics to the SCSI Inquiry command in the Vendor ID and the
Product ID fields. The defaults are: Vendor ID = DEC; Product ID TL800.

Set Date: Enables you to set the system’s calendar.

Set Time: Enables you to set the system’s clock.

Set Baud Rate: Enables you to set the data transmission rate of the Expansion
Unit’s trace port. This function is intended for use by Customer Engineers
only. The default is 38400 bits/sec.

Set Serial number: This setting enables you to alter the Expansion Unit’s
serial number as stored in the unit. The Module’s robotics reports these
settings in response to the SCSI Inquiry command, in the Unit Serial Number
Page.

Set Unload Mode: This setting determines whether a SCSI Move Medium
command is interpreted as implicit or explicit. If implicit, the Expansion
unloads a drive before attempting to move a cartridge from that drive. If
explicit, the host must issue a SCSI Unload command to the drive before each
Move Medium command from a drive to a slot. The default is Implicit.

Set Auto Clean Mode: This function, when enabled, will sense the tape
drive’s cleaning request and after the next unload, load a Cleaning Cartridge
into the drive. After cleaning is complete, the cartridge is returned to slot. The
default is disabled.

NOTE: This function is application dependent.
