A jumper switch consists of two metal pins across which a metal cover can be placed. By placing the cover across
the two pins, the pins are interconnected and the current bridge circuit is closed.
The hard disk is usually installed as the MASTER to the primary connector. If you now wish to connect a second
device to the same connector (and therefore to the same cable), this device must be set up as the SLAVE. It is
strongly recommended that you set up your CD-R/RW device as the MASTER and connect it to the secondary
connector. If necessary you can connect a second device to this cable as a SLAVE, but we advise against this as it
can affect the performance of your CD-R/RW.
Use a pair of long nose pliers to adjust the jumper switch at the back of your device. By default, the jumper switch is
set as the MASTER.
