Setting an ID Number
You can set an ID number for your drive by using the jumpers at the
back of the drive. The figure below shows the default jumper setting.
The jumpers have the following pin assignments shown in Table 3-1:
The first three pair of pins, pin 1,8, pin 2,9 and pin 3,10, allows you to
set your device ID. Table 3-2 shows you the possible ID numbers you
can set for your CD-R drive.
