SEPTEMBER 2005 MAGNUM 1X7 LTO AUTOLOADER
23-3
WHAT YOU SEND TO THE AUTOLOADER
Starting Element Address – Byte 02 and 03
This field specifies the minimum element address at which to start the search
for volume tag information that matches the template in the parameter list
(see page 23-3). Only elements with addresses greater than or equal to the
Starting Element Address are searched.
Note: The Starting Element Address must be 0 or a valid element address for the
autoloader, but does not have to be an address of the type requested in
the Element Type Code. Only the elements of the requested element type
are searched.
Send Action Code – Byte 05, Bits 4 through 0
This field defines the specific function to be performed by this command. The
autoloader supports a Send Action Code of 5h (translate, search all primary
volume tags, and ignore sequence numbers).
Parameter List Length – Bytes 07 through 09
This field specifies the length of the parameter list following this command.
The minimum length of the parameter list is 32 bytes (20h). The maximum
length is 40 bytes (28h).
23.2.1 SEND VOLUME TAG PARAMETER LIST
Volume Identification Template Field – Bytes 00 through 31
This field contains 32 bytes of volume identification information, which the
autoloader compares to the volume tag (bar code) information stored in
nonvolatile memory. Only the first eight bytes are valid. Any additional bytes
must be 0 (null). The template is considered terminated after the first 0 byte is
detected. This field may contain the following characters:
? (3Fh) – This character matches any single character at that position within the
field.
* (2Ah) – This character is a wild card that matches any characters from that
point on in that field. All characters past the “*” in the field are ignored.
