1st Import Export Element Address

The first import export element address field identifies the first import
export element contained in the medium changer.

Number of Import Export Elements

The number of import export elements field defines the total number of
import export elements contained in the medium changer. This field is
always zero.

1st Data Transfer Element Address

The first data transfer element address field identifies the first data transfer
element contained in the medium changer.

Number of Data Transfer Elements

The number of data transfer elements field defines the total number of data
transfer elements contained in the medium changer.

The default Medium Changer Element Address Assignment is as follows:
