WHAT YOU SEND TO THE AUTOLOADER
9.2.3 UNIQUE PROPERTIES PAGE (PAGE CODE 21H)
The Unique Properties Page sets options that are unique to the autoloader.
Page Code – Byte 00, Bits 5 through 0
This field identifies the Unique Properties page. The value of this field must be
21h.
Page Length – Byte 01
This field indicates the length, in bytes, of the Unique Properties parameter
list. The valid value for this field is 04h (4) which indicates that there are an
additional 4 bytes of data that follow this byte.
MaxStor – Byte 4, Bit 4
This field specifies whether the number of available storage elements is limited
to the value specified in the MaxStorAddr field, as follows:
0 – Do not limit the number of available storage elements (use all of the cartridge
cells as storage elements)
1 – Limit the number of available storage elements to the value specified in the
MaxStorAddr field.
The factory default is 0.
The MaxStor field is directly related to the Limit Cells option available from
the autoloader’s operator panel. The option to limit the number of cells can be
set, cleared, or viewed using the operator panel or by issuing a MODE
SELECT command with this field set to 1.
This field is kept in nonvolatile RAM, and once set, remains in effect, even
between power-on cycles, until changed by this command.
