Setting the Jumper Terminals

Configure the the jumpers to set the device to master or slave mode before physically installing it to your computer chassis. Use jumper blocks to short the pins to your desired setting.

CAUTION: Make sure to correctly place the jumper blocks over the pins. Failure to do so may cause irreparable damage to the drive!

Terminals

Master Mode

Cover the two pins labeled MASTER to set the CD-RW drive as a secondary master drive. This is possible only if your computer supports four IDE devices. The hard disk in the computer is set as Primary Master.

Slave Mode

Cover the two pins labeled SLAVE to set the CD-RW drive as a slave device if your computer supports only two IDE devices.

If your computer supports four IDE devices, this setting sets your CD-RW drive either as a Primary Slave or a Secondary Slave.

Cable Select Mode

Cover the two pins labeled CABLE SELECT if your computer supports a Cable Select (CSEL) signal. You need an exclusive interface cable for this setting. Refer to your computer manual for details.
