JUMPER SETTINGS

Toshiba's half-height CD-ROMs, CD-RW/DVD-ROM, DVD-ROMs and DVD-RAMs have jumper settings that may need to be changed in order for your drive to work properly. (The slim-line CD-ROMs and DVD-ROMs do not have jumpers.)

Jumper Settings:
ATAPI CD-ROM & CD-RW/DVD-ROM & DVD-ROM | SCSI CD-ROM & DVD-ROM | SCSI DVD-RAM

ATAPI CD-ROM, CD-RW/DVD-ROM and DVD-ROM Jumper Settings (Half-height drives only)
A block of mode select jumpers can be located on the rear of your CD-ROM, CD-RW/DVD-ROM or DVD-ROM. If a jumper covers both pins on the jumper block, it is ON; if there is no jumper or only one of the pins is covered, the jumper is OFF.

Mode Select Jumper	CS	Drive is configured using host interface signal CSEL
	SL	Configures drive as Slave
	MA	Configures drive as Master (default mode)

In most installations, jumper should remain in the MA position (factory default). It is recommended that you install your drive only on the secondary IDE BUS. If you are installing on primary IDE BUS, your hard drive would then be the Master, and you should set your drive to the Slave position (SL)

SCSI CD-ROM and DVD-ROM Jumper Settings (half-height drives only)

A block of mode select jumpers can be located on the rear of your CD-ROM or DVD-ROM. If a jumper covers both pins on the jumper block, it is ON; if there is no jumper or only one of the pins is covered, the jumper is OFF. The jumper settings include SCSI ID, Parity, Termination, Eject (except SD-M1401), 512/2K Block selectability (SD-M1401 only), Test and Power Supply.

SCSI ID - All SCSI devices attached to your computer are assigned a SCSI-ID number from 0 to 7. Your CD or DVD's SCSI ID must be set so that its ID number does not conflict with any other device's SCSI-ID in your system. In most cases, your CD or DVD will be set to SCSI ID 4 at the factory. Also note that your SCSI interface card in most cases has a SCSI ID of 7. This chart above shows the jumper settings for the eight possible ID numbers.

Parity - The Parity jumper should be in the "disabled" mode (no jumper present). When in the disabled mode, the drive does not check parity, although the output data is issued the parity bit.

Termination ON/OFF - This jumper turns termination power ON or OFF. If you are connecting more than one SCSI device to your system, and the CD or DVD is not at the end of the chain, then terminator jumper is not required.

PRV/ALW (all SCSI except the SD-M1401) - This jumper is used to inhibit the drive's EJECT button. When the jumper is ON, the EJECT button will not operate.

512/2K Block Selectability - (SD-M1401 only) - This jumper is used to select default block size. When the jumper is present, the default block size equals 512Bytes. When the jumper is not present, the default block size is 2048Bytes. This is effective for CD media only, not DVD media.

Test - This setting selects the drive operation between normal CD-ROM/DVD-ROM and CD-Audio player mode. When jumper is set to ON position, commands from the host computer are ignored. This jumper is for test purposes only and should be set to OFF for proper drive function.

Power Supply - Toshiba SCSI CD-ROM/DVD-ROM drives can supply power to other equipment on the SCSI BUS. When the jumper is ON, the drive will supply termination power. If you're not sure if any other device supplies termination power, it is fine to leave the jumper ON.

SCSI DVD-RAM Jumper Settings

A block of mode select jumpers can be located on the rear of your DVD-RAM. Jumper settings include SCSI ID, Parity, Verify, ONE LUN/TWO LUN, Test and Termination.

SCSI ID - All SCSI devices attached to your computer are assigned a SCSI-ID number from 0 to 7. Your DVD's SCSI ID must be set so that its ID number does not conflict with any other device's SCSI-ID in your system. In most cases, your DVD will be set to SCSI ID 4 at the factory. Also note that your SCSI interface card in most cases has a SCSI ID of 7. This chart above shows the jumper settings for the eight possible ID numbers.

DVD-RAM Jumpers

SCSI ID

Parity - The Parity Jumper should be in the "Enabled" mode (no jumper present). This causes the parity bit check function on the SCSI data bus to be activated which enhances data BUS reliability. The DVD-RAM is shipped with no jumper present.

Verify - The Verify Jumper pins should be set to OFF mode (no jumper present). When the jumper is in OFF mode, written data on the media is verified after the write operation. Writing speed is lower when in OFF mode, but data reliability.

ONE LUN/TWO LUN - The LUN jumper sets LUN (Logical Unit Number) on ONE LUN or TWO LUN mode. The default setting is no jumper present, which sets drive to ONE LUN mode.
ONE LUN mode: Standard mode (no jumper present)
TWO LUN mode: For testing only (factory use only) (jumper present)

Test - This jumper is for test purposes only and should be set to OFF (no jumper present) for proper drive function.

Termination ON/OFF - This jumper turns termination power ON (jumper present) or OFF (no jumper present). If you are connecting more than one SCSI device to your system, and the DVD-RAM is not at the end of the chain, then terminator jumper is not required.
