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.

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.

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-2¹CD-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.

The DRM-1804X is an 18-disc single drive SCSI-2 CD-ROM changer. It appears on the SCSI

bus as one SCSI ID with two (2) logical units. The single CD-ROM reader is logical unit 0 and

the changer is logical unit 1. For detail information, refer to Pioneer’s DRM-1804X CD-ROM

Jukebox Changer Mechanism Controller SCSI Specifications, document number OB-U0084-B.

The DRM series includes two jukebox changers - the DRM-1004X 100-disc CD-ROM changer

and the DRM-5004X 500-disc CD-ROM changer. For detail information, refer to Pioneer

publications DRM-1004X Series 100-Disc CD-ROM Changer Mechanism Controller

Specifications, document number DSE-S035C and DRM-5004X Series 500-Disc CD-ROM

Changer Mechanism Controller SCSI Specifications, document number OB-U0091-B,

respectively.

The DR-U series are SCSI-2 single disc CD-ROM drives. They appear on the SCSI bus as one

SCSI ID with logical unit 0.

The DR-D504X is a SCSI-2 single drive unit that is mounted into the DRM-5004X 500-disc

jukebox changer. It is assigned one SCSI ID and logical unit 0. 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.

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

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.

1.3.3

Status Phase

Four status conditions are supported. They are

GOOD

CHECK CONDITION

BUSY

RESERVATION CONFLICT

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.

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.

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.

³For 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.

2.5

Mode Select(6) (15h)

The MODE SELECT(6) command provides a range for the initiator specifying specific operating

parameters, e.g., medium, logical unit and peripheral device parameters.

IMPORTANT: Initiators should issue the MODE SENSE command (reference Section 2.7)

prior to each execution of the MODE SELECT command to determine supported pages, page

lengths and other parameters.

Operating Code is (15h).

PF (Page Format)

Must be set to “1” (TRUE). The drive does not check the value of the Page Format bit.

SP (Save Parameters)

Must be set to “0” (FALSE). Parameter saving is not supported.

Parameter List Length

If “0” (ZERO), no data will be transferred.

The Parameter List Length is the number of bytes of the Mode Select Parameter List that is

to be transferred in the Data Out phase. A parameter list length that results in the truncation

of any descriptor, header or page parameters will cause the target to terminate the

command. In this case Check Condition Status (Sense Key : Illegal Request) is returned

and Sense Code is set to Parameter List Length Error.

Using the MODE SELECT command, the initiator can assign or alter parameters for the logical

units. The Parameter List includes a 4-byte header, followed by 0-1 block descriptors and 0-N,

where N is a whole number, page descriptions. Refer to Table 2-5A on the opposite page. The

drive keeps parameters, the block descriptor and parts of page descriptors for each logical unit in

its controller memory. When the drive is reset, the default parameter values are restored.

Refer to Table 2-5B on the next page for details on the Block Descriptor format.

Refer to Table 2-5C on the next page for details on the Page Descriptor format.

After the MODE SELECT command is received, the drive returns Check Condition Status

(Sense Key : Unit Attention) and sets sense key to Mode Select Parameter Changed for the first

command received (except for INQUIRY or REQUEST SENSE) from any other initiator. The

Sense Key Unit Attention is returned even if the parameters have not actually changed with the

MODE SELECT command.

Error Recovery Parameters

NOTE: When the bit definition of this error recovery parameter and the error recovery

procedure (described later) are not in agreement, the error recovery procedure takes

priority.

DCR (Disable Correction)

If “1”, data is transferred without Layered ECC (L-ECC) error correction.

If “0”, L-ECC error correction is performed. The default value is 0.

DTE (Disable Transfer on Error)

If “0”, transfer of recovered data is allowed. The default value is 0.

When both the DTE and PER bit are 1, the target stops the data transfer

immediately if the error is detected, and then returns Check Condition status.

NOTE: The TB bit controls whether data from the bad block is transferred.

PER (Post Error)

If “1”, the drive returns a Check Condition status for a recovered error.

If “0”, no Check Condition status is returned for the recovered error.

The default value is 0.

EEC (Enable Early Correction)

This bit must be 0: The defined retry procedure is performed prior to the error

correction.

RC (Read Continuous)

Set to 0. A delay in the data transfer may occur due to an error recovery action.

TB (Transfer Block)

If “1”, uncorrected data blocks will be transferred to the initiator.

If “0”, uncorrected data blocks are not transferred. The default value is 0.

NOTE: in either case, the block address returned to the REQUEST SENSE command

is not of the preceding good block but of the error block.

Retry Number specifies how many times the drive re-tries a physical read operation

when it finds an uncorrectable block. The default value is 4.

Logical Block Address

The logical block address field specifies the logical block at which the audio play back

operation will begin. If all bytes in the logical block address field are set to FFh, it means

to start at the current optical head location. This feature allows the host to modify the audio

ending address without interrupting the current audio playback operation.

Transfer Length

Specifies the number of contiguous logical blocks that will be played. A transfer length

field of zero indicates that no audio operation will occur. This condition will not be

considered an error. Any other value indicates the number of logical blocks that will be

played.

The PLAY AUDIO(10) command requests that the target play audio starting at the specified

logical block address for the specified transfer length. The command function (Immed bit) and

the output of audio signals will be as specified by the settings of the audio control parameters in

the MODE SELECT PAGE CODE E.

The status returning condition depends on the Immed bit of MODE SELECT page code E. The

Immed bit in MODE SELECT page code E of one requests that this command return the status

byte as soon as the audio playback operation has been started. The Immed bit in MODE

SELECT page code E of zero requests that this command return the status byte when audio

playback operation is completed, or an error occurs.

If any commands related to audio operations are implemented then the PLAY AUDIO command

will be implemented to allow a method for the initiator to determine if audio operations are

supported. A target responding to a PLAY AUDIO command which has transfer length of zero

with Check Condition status and setting the sense key to ILLEGAL REQUEST does not support

audio play operations.

C2 & Block Error Flags Both the C2 Error Flags (2352 bits or 294 bytes) and the

Block Error Byte will be included in the data stream.

The Block Error byte is just the longitudinal parity of all

the C2 Error Flag bytes, So that the data stream will

always be an even number of bytes, the Block Error byte

will be padded with a 0 byte. The Block Error byte will

be first in the data stream followed by the pad byte.

Support of Sub-channel data is optional. In the case of R-W the drive may return data de-

interleaved and error-corrected, RAW or padded with zeros depending on the R-W Supported

and R-W de-interleaved and error-corrected bits in the CD-ROM capabilities and mechanical

status page.

If the Starting Logical Block Address is set to FFFFFFFFh and the only information requested to

be placed in the data stream is the Sub-channel data and there is currently a PLAY AUDIO

command in process, the actual address used will be from the current location (of the Audio

play).

The number of bytes returned is based on which bits are set in the Data Selection Field.

The table on the opposite page allows you to calculate the number of bytes returned based on

which Data Selection field bits are set.

The CD-DA audio data includes 16bits of information for each channel, and will be formatted as

follows when an audio track is read. The First Channel is Left channel, and Right channel is

next.

2.24 Read CDP (E4h)

Operation Code is (E4h)

This command requests the drive to return the status data resulting from the previous WRITE

CDP command. The drive terminates the data phase when Allocation Length bytes or all the

relevant data have been transferred.

The last status data returned from the Drive Controller is buffered in the drive SCSI controller.

Because the next return data from the next WRITE CDP command will overwrite the buffer, the

READ CDP command should immediately follow a WRITE CDP command.

The buffered status data is cleared after executing a READ CDP command. If a READ CDP

command is issued after the buffer is cleared, the drive does not go to the data phase, but returns

a GOOD status.

If a READ CDP command is issued during the execution of a player operation, a BUSY status is

returned. Any command other than the READ CDP is accepted. If the drive receives a SCSI

command (except the INQUIRY or REQUEST SENSE commands) the action initiated by the

WRITE CDP command will be terminated. In this case, the player status returned by the READ

CDP command will be "E16" (Input From Other Device). Such a player interrupt does not cause

any SCSI errors.

See Appendix B for information on the CDP return codes.

The Start Track field specifies the starting track number for which the data shall be returned. If

this value is zero, the table of contents data shall begin with the first track on the medium. The

data is returned in contiguous ascending track number order.

If the Start Track field is not valid for the currently installed medium, the command shall be

terminated with Check Condition status. The sense key shall be set to ILLEGAL REQUEST and

the additional sense code set to INVALID FIELD IN CDB.

IMPLEMENTORS NOTE: The maximum TOC data length possible on currently available CD-

ROM media is 804 bytes, or 100 TOC track descriptors.

The TOC data block contains a four byte header followed by zero or more TOC track descriptors.

The TOC data length specifies the length in bytes of the following TOC data that is available to

be transferred during the DATA IN phase. The TOC data length value does not include the TOC

data length field itself.

The first track number field indicates the first track number in the table of contents. The last

The first track number is not required to be one. A disc may start at any valid track

number. The track numbers between the first track number and the last track number are

required to be in contiguous ascending order, except for the lead-out track.

The ADR field gives the type of information encoded in the Q sub-channel of the block where

this TOC entry was found. The control field indicates the attributes of the track.

The track number field indicates the track number for which the data in the TOC track descriptor

is valid. A track number of 0AAh indicates the track descriptor is for the start of the lead-out

area.

The absolute CD-ROM address contains the address of the first block with user information for

that track number as read from the table of contents. An MSF bit of zero indicates that the

absolute CD-ROM address field contains a logical block address. An MSF bit of one indicates

the absolute CD-ROM address field contains an MSF address.

IMPLEMENTORS NOTE:

The starting logical block address value recovered from the TOC has a tolerance of zero for

data tracks and plus or minus 75 CD sectors for audio tracks. This tolerance is multiplied

by a factor dependent of the logical block length.

The initiator uses this command to exclusively reserve the specified logical unit. Area

reservations using the Extent bit are not supported. If the 3rd Party bit is 1, the logical unit is

reserved for another SCSI device specified by the 3rd Party Device ID. The initiator can change

the reservation by issuing a new RESERVE UNIT command to the reserved unit. In this case,

the previous reservation is released when the new reservation is received.

The reserved condition is maintained until the original initiator issues another valid RESERVE

UNIT command or a RELEASE UNIT command; when a BUS DEVICE RESET message is

issued by any initiator; or when a hardware reset condition occurs. In the latter two reset cases, a

UNIT ATTENTION condition is reported for the next SCSI command.

Any reservation request by an initiator for a logical unit that has been reserved by another

initiator is rejected, and a RESERVATION CONFLICT status is returned.

If the 3rd Party bit is 1, the logical unit is reserved for the SCSI device indicated by the 3rd-

Party Device ID. The reserved state is maintained as described previously. Any release request

is ignored, and a GOOD status is returned if it comes from an initiator other than the one that

issued the reservation command.

The Transfer Length specifies the number of contiguous CD-DA data blocks to be transferred.

- 157 -

C D-ROM SC SI-2 C OMMAND REFERENC E MANUAL VERSION 3.1 (OB-U0077C )

NOTES:

1) The CD-DA block lengths are totally irrelevant to the logical block length set by the

Mode Select(6) command. This command would not change the block length field in the

MODE SELECT command.

2) While the SCSI buffer is being filled, the drive is able to prepare with no overlap or

missing data in response to the consecutive commands which read contiguous CD-DA

blocks.

When the host cannot read the data quick enough and the buffer is full, the drive will stop

refilling the buffer. The host is still capable of reading all CD-DA data in the SCSI buffer

with consecutive read commands without overlap or missing bits at the block boundary.

Once the buffer is full, the first read command to read the next sequential CD-DA

block(e.g. X+1) after the last CD-DA block(e.g. X) in the buffer will cause a Check

Condition with a sense key of 05h and an additional sense code of BAh(buffer overflow).

There is no check condition for a read command which does not request block X+1(e.g. a

Read(X+2, 1) command). In addition, a second read command which requests block X+1

will not get a check condition.

For Example (In case that the last CD-DA block stored in the buffer is X):

In a Read(X-2, 5) command to read block X-2 to X+2, the drive returns three CD- DA data

blocks and then a check condition. The drive returns the block X+1 address in the

information bytes(byte 3 to 6) of a subsequent Request Sense command. There are no

overlap of missing bits for blocks X-2, X-1 and X. Block X and X+1 are not transferred.

That is; in case of reading CD-DA blocks, the drive has only rough access. Once the data

stream from the media has been stopped, it is unable to have such pin-point access as in

CD-ROM blocks. (Each CD-ROM block always includes the CD-ROM Header that

provides the pin-point access.)

3) The volume level control is not performed on any SCSI CD-DA data. Analog audio

output is not performed while SCSI CD-DA data is in transaction, either.

4) The drive transfers data to the host at the burst transfer rate for the entire block of data.

The drive's firmware overhead should only occur at a block boundary. Upon completion of

the read operation, the drive enters the Hold Track state during inactive time.

data and a block of 294 bytes Error Flag data.

NOTE: The CD-XA block length is totally irrelevant to the logical block length set by Mode

Select Command.

IMPORTANT: This command applies only to models DRM-602X, DRM-624X, and the DR-U

Series drives.

Operation Code is (DFh)

Transfer Length indicates the number of contiguous sub-code frames to be transferred. Each

sub-code frame consists of 96-byte data.

Read All Subcode command directs the target to transfer real-time sub-code data (P-W) to the

initiator while the audio is being played.

The initiator must hold while the current sub-code is being retrieved from the disc.

If the Transfer Length is zero, sub-code data will not be transferred. In this case, however, it is

not considered an error.

In the event the sub-code buffer is full in the drive, the drive will stop storing sub-code data into

the buffer. However, the data in the buffer is accessible by this command.

The drive will quit the operation with a Check Condition status once the buffer overflows

or there is no more valid sub-code data in the buffer. The sense key is set to 05h and the

additional sense code is to BFh. The Check Condition for buffer overflow occurs only for the

READ ALL SUBCODE command.

If the target is not playing the audio, the drive will return a Check Condition status.

The sense key is set to 05h and the additional sense code is to 64h.

NOTE: The drive transfers an entire block of data at SCSI bus burst transfer rate. The drive's

firmware overhead only occurs at a block boundary. Upon completion of the read operation, the

drive enters the Hold Track state during the inactivity time.

Appendix A

APPENDIX A PIONEER CD-ROM DRIVES - AUDIO FUNCTIONS

The CD-ROM drives consist of two logical subsystems - a CD reader and a controller. The controller

receives SCSI commands, and sends commands to the reader for execution as needed. This allows audio

commands to be executed in the background. At times, the two subsystems may be operating

independently.

In addition to the normal audio commands, the CD-ROM drives support the Pioneer Laser Disc Player

control commands. These alphanumeric mnemonics may be sent to the drive using the vendor-unique

command WRITE CDP (Character Device Player). The WRITE READ CDP command strings are

passed through the controller directly to the reader. The controller checks the length and termination of

the command string, and, if valid, returns a GOOD status. The controller will generate a Check

Condition with a sense key of ILLEGAL REQUEST if the string is not valid. The controller then passes

the command string to the reader for execution. To receive the results of the command string, the

initiator must use the READ CDP command to get the status from the reader. The reader passes the

result data through the controller. Invalid commands or execution errors will not cause SCSI errors, but

will be reported by the READ CDP command.

Certain types of data, such as the disc TOC, are stored by the controller once they have been read from

the disc. If a disc has been accessed, a READ TOC command will not require a disc access, which could

include a disc change. Instead, the TOC data is transferred from controller memory.
