Overview
1.1.5 The Pioneer CD-ROM Reader
1
The Pioneer CD-ROM reader DR-D504X is a 4X speed CD-ROM drive
and includes audio outputs for CD-DA. (When digital audio is present,
the drive automatically outputs audio at single speed.) On the rear
panel, there are also four sets of stereo audio outputs, one for each of
up to four drives installed. Each CD-ROM reader within the unit is
assigned its own specific SCSI ID address on a SCSI chain and is
controlled by SCSI commands sent from a host computer.
1.1.6 The Pioneer CD-ROM Writer
The 4x speed Pioneer CD-ROM Writer (DR-R504X) is also available as
an option. The writer can write data to CD-Recordable (Write Once)
discs (CD-R discs) at 4X speed or 2X speed. When the writer is
installed in the DRM-5004X, it is usually addressed independently on
its own SCSI chain so writing a CD-R disc can take place without
interruption.
1.1.7 SCSI Connections
There are a total of five SCSI ID Setting Switches on the rear panel of
the unit: one to set the SCSI address of each drive installed and one
to set the SCSI address of the changer mechanism. There are six SCSI
connectors on the rear panel. Typically, when the unit is shipped, the
controller and installed Pioneer CD-ROM readers are daisy chained
starting at SCSI Port A. The SCSI chain is terminated by placing the
terminator block, included as an accessory, on SCSI Port B.
1.1.8 Connecting Drives on Separate SCSI buses
Internal drives can also be connected to separate SCSI buses using
the other SCSI connectors on the rear of the the unit. For example,
when one CD-R writer is added, it can be connected to an unused
SCSI connector on a separate SCSI bus to assure there are no inter-
ruptions while writing data to a CD-R disc. Refer to instructions in
Section 4.6, Custom Configuration.
