FCC INFORMATION

The equipment described in this manual has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in Part 15 of FCC rules. These specifications are designed to provide reasonable protection against radio and television reception interference in a residential installation. There is no guarantee that interference will not occur in a particular installation.

To determine if your CD-ROM drive is causing interference, turn the drive off. If the interference stops, it was most likely caused by the drive. To eliminate the interference, you may try one or more of the following corrective measures:

• verify the cables and connectors between components are shielded.

• increase separation between the drive and components.

• connect the drive into an outlet or circuit different from that which the components are

connected.

• consult dealer or experienced radio/television technician for help.

The Federal Communications Commission offers a handbook that may help you with eliminating interference. The handbook is titled Interference Handbook (stock number 004-000-00493-1) and may be ordered from the U.S. Government Printing Office, Washington, D.C. 20402.

WARNING: Any changes or modifications to this product that are not authorized by Pioneer could void the FCC Certification and negate the user’s authority to operate the equipment.

DOC CLASS B COMPLIANCE

This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus set out in the radio interference regulations of the Canadian Department of Communications.

1. PREFACE

These specifications define the SCSI command set that defines the interface between a host computer and such primary devices as CD-ROM drives and CD-R writers.

These are the control functions for the Pioneer DRM/DR-U series CD-ROM drives. For specific models, refer to Section 1.1 below.

For details of the common standard of SCSI, refer to ANSI SCSI-2 working draft X3T9.2 revision 10K.

For details regarding the use of the compact disc as a SCSI CD-ROM device, refer to the proposal made after the ANSI SCSI-2 working draft X3T9.2 revision 10K.

For Compact Disc, CD-ROM disc, and CD-R disc specifications, refer to the Red Book, Yellow Book and Orange Book Part2.

Preface

For file system specifications, refer to ISO 9660.

For details about the use of SCSI Bus, refer to the installation manuals of the particular drives.

For more information on player control commands (mnemonic commands), refer to Appendix B of this document and/or Pioneer Industrial LaserDisc Player (any model) User’s Manuals.

THESE SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE.

1.1 DRM/DR-U Series

The six-disc DRM series drives are SCSI-21 CD-ROM minichangers using a single movable optical assembly and a removable Pioneer-developed 6-disc CD magazine. Six discs may be stored in individual trays in the magazine. Each tray swings out of the magazine into the drive assembly. Only one disc may be read at a time. The minichanger appears on the SCSI bus as one SCSI ID with six (6) logical units (0-5), one logical unit assigned per disc. The assignment of logical units to discs may be changed at any time.

DRM-604X is the only minichanger that supports both the SCSI-1 and SCSI-2 command sets. Please refer to Pioneer’s DRM-600

Series SCSI Command Reference Manual for details on the SCSI-1 command set.

Refer to Pioneer’s DRM-5004X Series 500-Disc CD-ROM Changer Mechanism Controller SCSI Specifications, document number OB-U0091-B, for further details.

Implementing Pioneer’s LaserDisc player technology, vendor unique SCSI commands support the alphanumeric player command set allowing CD audio control through use of simple mnemonic commands. Refer to Appendices A and B for further information.

Table 1.1 on the opposite page lists the models supporting the SCSI-2 command set.

1.2 Drives Supported by this Manual

Refer to Table 1-2 on the opposite page for drive versions that are supported by this manual. To determine what version your drive is, issue an IQUIRY command, reference Section 2.4. The drive’s response to the command will be to return the following information about the drive:

Model Number; Vendor; Product Data; and Revision Number.

1.3 SCSI Protocol

The SCSI Protocol outlined in this section applies only to SCSI bus models. It does not support ATA bus models.

1.3.1 Command Link/Control Field

The Control Field inside the Command Block is defined as:

Bit 7 6 5 4 3 2 1 0

Vendor Unique Reserved Flag Link

The Command Link function is not supported by the DRM/DR-U Series. Set Flag and Link bits to “0” (FALSE).

Set the RelAdr (Relative Address) bit, bit 0 of byte 1, inside the Command Block to “0” (FALSE).

1.3.2 Disconnect/Reselect

Selection time-out period is 250 ms.

If the initiator does not respond to reselection within the time-out period, the drive will release the bus for a minimum of 200 ms. The drive will then repeat the arbitration/reselection sequence until the initiator responds, issues BUS DEVICE RESET, or until the SCSI bus is reset. During a reselection retry, the drive will return BUSY to selection requests from any initiator.

During execution of audio commands, if the disconnect/reselect function is selected, the drive disconnects from the initiator before execution a SEEK or other operation that requires head movement. When the selected address is located, the drive reselects the initiator and begins audio playback. The time needed for the reselection procedure is dependent upon the status of the SCSI bus. Audio playback may begin before the reselection is complete. Refer to Appendix A for more information.

- 5 -

1.3.3 Status Phase

Four status conditions are supported. They are

GOOD 00h CHECK CONDITION 02h BUSY 08h RESERVATION CONFLICT 18h

When the IMMED bit is set to “1” (TRUE) in a command block, the drive returns GOOD when the command is first interpreted. As the command is being executed, the drive returns BUSY to successive commands until operation of the first command is complete and the drive is ready to receive a new command.

Refer to Section 2.31 REQUEST SENSE for details on deferred error reporting.

Preface

1.3.4 In-Phase/Out-Phase Messages

The DRM/DR-U Series supports only those In-Phase and Out-Phase Messages that are listed below and on the following page. The drive will return a MESSAGE REJECT for any messages received other than those listed.

Message Msg 05h + 09h will cause the drive to go to BUS FREE PHASE without a retry.

1.4 Address Format for Answering Occasion (MSF bit)

With some commands, it is possible to choose either Logical Block Address or MSF Format with Address Field of answering data.

Preface

0Ch

01h

MSF bit

if “0” (FALSE), use Logical Block Address as CD-ROM Absolute Address or Track Relative Address. If Track Relative Address, the MSF bit is indicated by 2s sequences.

if “1” (TRUE), MSF Format is used. Within the shift area, number declines by a positive number.

1.5 Sample Command

The table on the opposite page outlines the command structure. Some commands apply to the entire drive. For these commands only, the LUN will be ignored.

Commands with Logical Blocks, e.g. READ, VERIFY, have Allocation Length in Blocks. All others have Allocation Length in bytes. Some commands use Transfer Length instead of Allocation Length to specify the number of bytes that the initiator will transfer to the drive.

For equipment supporting Change Definition Command, the DRM/DR-U Series drives have a Hardware Reset Option. In this case, the Change Definition chosen by the SCSI action definition would not be changed or initialized by either the SCSI BUS RESET or BUS DEVICE RESET message.

2.1 Audio Scan (1) (CDh)

When AUDIO SCAN (1) is executed, the drive begins a high-speed scan from the Scan Start Address. The drive plays a block as it crosses each track. Each scan is approximately 15 seconds.

When the specified search address is found, GOOD status is returned.

If the drive is not ready or if the Scan Start Address is not on an audio track, Check Condition status is returned.

During an audio scan, the drive can receive and execute the following SCSI commands without scan termination:

AUDIO PLAY (StpAdr=1), AUDIO STATUS, AUDIO STOP INQUIRY MODE SELECT, MODE SENSE READ BUFFER, WRITE BUFFER READ CD-ROM CAPACITY, READ SUB CHANNEL, READ TOC RECEIVE DIAGNOSTIC RESULTS, REQUEST SENSE, TEST UNIT READY RELEASE, RESERVE

Audio Scan (1)

There are several commands that when received by the drive during an audio scan, the drive will terminate the scan and execute the received command. The commands are:

PLAY AUDIO (StpAdr=0), AUDIO SCAN, PLAY AUDIO TRACK PAUSE/RESUME READ, SEEK, VERIFY READ HEADER START/STOP UNIT, REZERO UNIT SEND DIAGNSTICS PREVENT/ALLOW MEDIA REMOVAL

Operation Code is (CDh).

Direct

is “0” (FALSE) when the drive scans forward. is “1” (TRUE) when the drive scans backwards.

Scan Start Address contains the address at which the audio scan is to begin.
