Position To Element Command (2BH)
This command positions the specified transport element in front of the
specified destination element.
Transport Element
Address The default address of zero is the best address for use.
(Changing from the default could result in a decrease in
jukebox performance.) However, this field can also be
set to a specific transport element address (see Table 3-
22 on page 3-23).
Destination Element
Address See Table 3-22 on page 3-23 in the description of the
Mode Sense Command for more information about
addressing.
Invert An Invert bit value of 1 requests the transport element
be inverted (flipped) before being placed in front of the
destination element.
