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
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 3-1 defines 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.

3.3.1.1 Cable Select (CS) Jumper
When a MaXLine Plus II 250GB AT hard disk drive and another ATA hard disk
drive are daisy-chained together, they can be configured as Master or Slave either by
the CS or DS jumpers. To configure the drive as a Master or Slave with the CS
feature, the CS jumper is installed (1). The drive's position on the 80 conductor Ultra
ATA data cable then determines whether the drive is a Master (Device 0) or a Slave
(Device 1). If the drive is connected to the end of the Ultra (cable Select) data cable
the drive is a Master. If the drive is connected to the middle connection it is set as a
Slave.
