There have been five (5) series of Pioneer optical drives: 5000, 5100, 7000, 7100 and 9100. The 5000,
5100 and 7000 series were all SCSI-1 type devices and are no longer in production. The 7100 and 9100
series are switchable SCSI-1 and SCSI-2 devices and are still being produced.
NOTE: SCSI-2 is the current prevalent industry standard.
DE-7001 Series
The DE-7001 series includes the DE-S7001 and DE-U7001 models. The DE-S7001 is an external
subsytem including drive unit, SCSI controller and DC power supply. The DE-U7001 is an internal full
height drive unit with SCSI controller. Both models use the DEC-702 rewritable (MO) magneto-optical
disk media and the DC-502
A
WORM (Write Once Read Many) optical disk media.
The 7001 series drives must be set to Mode 0 when using Rewritable media and to Mode 1 when using
WORM media. The settings of the dip switch bits 7 and 8 determine which mode the drive is set to. The
dip switch is located on the rear of the DE-S7001 and on the controller board of the DE-U7001.
The bit settings are read by the controller at Power ON and RESET. If the settings of the bits have
changed, the unit must be reset or turned OFF and then ON before the new setting will take place.
IMPORTANT: You should only change the bit settings when power to the device is OFF.
NOTE: The Mode setting may also be changed by sending the SCSI command CHANGE MODE. Refer
to the SCSI specifications for the corresponding drive for more details.
The Modes are set as described in the table below:
Mode Bit 7 Bit 8 Name Description
0 OFF OFF Rewritable Mode Read and write operations are enabled only with ISO
standard (sampled servo format) rewritable disks. Read
and write operations with WORM disks are disabled.
1 OFF ON WORM Mode Read and write operations are enabled only with ISO
standard (sampled servo (SS) format WORM disks.
Read and write operations with rewritable disks are
disabled.
