7.10 Drive address setting

A jumper is available at the interface connector to determine the drive address. The set position of the
jumper is as shown below.
Using Cable Selection, 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 logic high, the drive is a
Slave.

2—Device 1 (Slave)
3—Cable Select
4—Never attach a jumper here
5—Never attach a jumper here
Note: When pin C is grounded the drive does not spin up at POR.
