PlexCombo 20/10/40-12A Installation and Users Manual
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 jumper.
Figure 5: Install the Mode Jumper Across Vertical Pairs of Pins
CAUTION: Install the mode jumper across each pin 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.
Select an IDE Configuration
Set the jumper according to the desired configuration, as shown in the tables and
illustrations on the next few pages.
NOTE: For best CD-RW performance, try to connect the PlexCombo to the IDE port
that is not connected to the hard disk drive or to a CD-ROM drive. In most cases, this
will be the secondary IDE port.
NOTE: For best results, set the PlexCombo to be the Master, if possible. DMA setting
must be enabled on your system to achieve the drive’s maximum writing speed.
