A jumper is available at the interface connector to determine the drive address.

Note: When cable selection is used (Jumper Pos 3 selected), the drive address depends on the condition of pin 28 of the AT interface cable. In the case when pin 28 is ground or low, the drive is a master. If pin 28 is open or high level, the drive is a slave.  The drive is shipped with no jumper installed (Master).
