Section 2. Installing the PX-712A Internal ATAPI Drive
Changing to a Master, Slave, or Cable Select
The Master/Slave/Cable Select setting for the drive is determined by the
mode jumper. The jumper is placed over one of the sets of mode pins.
To change the drive from Master to Slave or to Cable Select, you must
move the jumper.
For example, to change the drive to be a Slave, move the jumper to the
middle set of mode pins, leaving the other pins uncovered. To change
the drive for Cable Select, move the jumper to the left set of mode pins.
Note that if any device is jumpered as Cable Select, then both devices
connected to that cable must be jumpered as Cable Select. In addition,
the cable you use must be a special Cable Select cable.
Changing Jumper Settings
• To remove a jumper, pull it off with your fingers or a pair of needle-
nose pliers.
• To install a jumper, push it onto the jumper pins.
CAUTION: Ensure power to the drive is OFF before installing or
removing a jumper.
Figure 5: Install the mode jumper across vertical pairs of pins
CAUTION: Install the mode jumper across the pins as shown (vertically).
Do not connect one pin switch to another by installing the jumper
lengthwise (horizontally). Doing so could result in damage to the drive.
