Set the Drive’s Jumpers
You specify your drive's master or slave setting before installing it. You do this by
changing the position of a jumper on the jumper block at the rear of the drive.
Your drive ships from our factory with its jumper set to operate the PlexWriter as a
master. This will work in the most commonly found environments.
Changing the Jumper on Your Internal PlexWriter Drive
As shown in Figure 4, the PlexWriter drive arrives from the factory with its jumper
set to MASTER. (A function is ON if the jumper is installed and OFF if the jumper
is removed.)

Changing to a Master, Slave, or Cable Select
The Master/Slave setting for the drive is determined by the jumper. To change the
drive from Master to Slave or to Cable Select, you must move the jumper.
For example, to change the PlexWriter drive to be a Slave, move the jumper to the
middle set of pins, leaving the other pins uncovered. To change the drive for Cable
Select, move the jumper to the left set of pins.
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 jumpers.
