Installation

The configuration of the following three jumpers controls the drive’s five modes of operation:

•CS – Cable Select

•DS – Drive Select

• CLJ– Cylinder Limitation Jumper

• POSB - Power on standby (Remote Command)

The AT PCB has two jumper locations provided to configure the drive in a system. The default configuration for the drive as shipped from the factory is with a jumper across the CS location, and open positions in the DS and CLJ positions.

Table 3-1defines the operation of the master/slave jumpers and their function relative to pin 28 on the interface. 1 indicates that the specified jumper is installed; 0 indicates that the jumper is not installed.
