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-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. 1 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. -1- CD-ROM SCSI-2 COMMAND REFERENCE MANUAL VERSION 3.1 (OB-U0077C) TABLE 1-0 MODELS OF DRM/DR-U SERIES SUPPORTING SCS-2 COMMAND SET Model Number DRM-602X DRM-604X DRM-624X DRM-1804X DR-D504X DR-U124X DR-UA124X DR-A10X DR-U10X DR-411 DR-433 DR-A12X DR-U12X DR-444 DR-466 DR-A24X DR-U24X DR-511 DR-533 TABLE 1-2 Voltage Requirements 100 v ~ 230 v 100 v ~ 230 v 100 v ~ 230 v 100 v ~ 230 v DRM-5004X 500-disc Autochanger built-in use +5 v. +12 v +5 v. +12 v ATA BUS mode1 +5 v. +12 v ATA BUS mode1 +5 v. +12 v +5 v. +12 v OEM version of DR-A10X +5 v. +12 v OEM version of DR-U10X +5 v. +12 v ATA BUS mode1 +5 v. +12 v +5 v. +12 v OEM version of DR-A12X +5 v. +12 v OEM version of DR-U12X +5 v. +12 v ATA BUS mode1 +5 v. +12 v +5 v. +12 v OEM version of DR-A24X +5 v. +12 v OEM version of DR-U24X DRIVE VERSIONS SUPPORTED BY THIS MANUAL Model Number DRM-602X DRM-604X DRM-624X DRM-1804X DR-D504X DR-U124X DR-UA124X DR-A10X DR-U10X DR-411 DR-433 DR-A12X DR-U12X DR-444 DR-466 DR-A24X DR-U24X DR-511 DR-533 Vendor Pioneer Pioneer Pioneer Pioneer Pioneer Pioneer Pioneer Pioneer Pioneer Pioneer Pioneer Pioneer Pioneer Pioneer Pioneer Pioneer Pioneer Pioneer Pioneer Product Data CD-ROM DRM-602X CD-ROM DRM-604X CD-ROM DRM-624X CD-ROM DRM-1804X CD-ROM DR-D504X CD-ROM DR-U124X CD-ROM DR-UA124X CD-ROM DR-A10X CD-ROM DR-U10X CD-ROM DR-A10X CD-ROM DR-U10X CD-ROM DR-A12X CD-ROM DR-U12X CD-ROM DR-A12X CD-ROM DR-A12X CD-ROM DR-A24X CD-ROM DR-U24X CD-ROM DR-A24X CD-ROM DR-U24X -2- Revision Number 2901 or greater 2403 or greater 0100 or greater 0100 or greater 2405 or greater 0100 or greater 0100 or greater 0100 or greater 0100 or greater 0100 or greater 0100 or greater 0100 or greater 0100 or greater 0100 or greater 0100 or greater 0100 or greater 0100 or greater 0100 or greater 0100 or greater Preface 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.

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. -3- CD-ROM SCSI-2 COMMAND REFERENCE MANUAL VERSION 3.1 (OB-U0077C) 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 Vendor Unique 4 3 Reserved 2 1 0 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. -4- Preface 1.3.3 Status Phase Four status conditions are supported. They are GOOD CHECK CONDITION BUSY RESERVATION CONFLICT 00h 02h 08h 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. 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.

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. 3 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. 4 From EXTEND MESSAGE (01h). -7- CD-ROM SCSI-2 COMMAND REFERENCE MANUAL VERSION 3.1 (OB-U0077C) The drive terminates the DATA IN phase when the specified number of bytes have been transferred or, in the case when the bytes exceed the number of bytes the drive wishes to transfer, the DATA IN phase is terminated when the number of bytes prepared have been transferred. -8- Table 2-0 Command Name SCSI-2 COMMAND LIST (by Name) Applied Model I II III Code Audio Scan (1) Audio Scan (2) Change Definition Inquiry Mode Select(6) Mode Select(10) Mode Sense(6) Mode Sense(10) Pause/Resume Play Audio (10) Play Audio (12) Play Audio MSF Play Audio Track/Index Play Track Relative (10) Play Track Relative (12) Prevent/Allow Medium Removal Read (6) Read (10) Read (12) Read Buffer Read CD Read CD-DD Read CD MSF Read CD-DA MSF Read CD-XA Read All Subcode Read CD-ROM Capacity Read Header Read Sub-Channel Read TOC Receive Diagnostic Results Release Request Sense Reserve Rezero Unit Seek (6) Seek (10) Send Diagnostic Set CD-ROM Speed (1) Set CD-ROM Speed (2) Start/Stop Unit Stop Play/Scan Test Unit Ready Verify (10) Verify (12) Write Buffer Read CDP Read Drive Status Write CDP BAh CDh 40h 12h 15h 55h 1Ah 5Ah 4Bh 45h A5h 47h 48h 49h A9h 1Eh 08h 28h A8h 3Ch BEh D8h B9h D9h DBh DFh 25h 44h 42h 43h 1Ch 17h 03h 16h 01h 0Bh 2Bh 1Dh BBh DAh 1Bh 4Eh 00h 2Fh AFh 3Bh E4h E0h E3h --yes 1 yes 2 2 2 2 yes yes yes yes yes yes yes yes yes yes yes yes ------------yes yes yes 4 yes yes yes yes yes yes yes yes --yes yes --yes yes yes yes yes yes yes --yes --yes 2 2 2 2 yes yes yes yes yes yes yes yes yes yes yes yes --yes --yes yes yes yes yes yes yes yes yes yes yes yes yes yes yes --yes yes --yes yes yes yes yes yes yes 7 7 --yes yes yes yes yes yes yes yes yes yes yes yes yes yes yes yes yes 3 3 3 3 yes 7 yes yes yes yes yes 5 yes 5 yes yes yes yes yes yes yes yes yes ----5 yes yes yes Sense Data Contents of Information Bytes Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Logical Block Address Commands 2.

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. - 25 - CD-ROM SCSI-2 COMMAND REFERENCE MANUAL VERSION 3.1 (OB-U0077C) TABLE 2-5B BLOCK DESCRIPTOR Bit Byte 7 6 5 4 3 0 Density Code 1 Number of Blocks (MSB) 2 Number of Blocks 3 Number of Blocks (LSB) 4 Reserved 5 Block Length (MSB) 6 Block Length 7 Block Length (LSB) TABLE 2-5C 2 1 0 2 1 0 PAGE DESCRIPTOR Bit Byte 7 6 0 Reserve Reserve 5 4 3 Page Code 1 Page Length 2 Mode Parameter Page Definition : : N Mode Parameter Page Definition - 26 - Mode Select(6) BLOCK DESCRIPTOR Media Type Set to “0” (ZERO).

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.

A Resume bit of one indicates that the drive release the pause and begin play at the block following the last block played. The PAUSE/RESUME command requests that the drive start or stop the current audio play operation. This command is used with PLAY AUDIO commands, issued while the immediate bit(Immed) of MODE SELECT PAGE CODE E is set to one. This command is terminated with Check Condition status if the resume bit is zero and the audio play operation cannot be paused (i.e. an audio play operation has not been requested, or the requested audio play operation has been completed). It will not be considered an error to request a pause when a pause is already in effect or to request a resume when a play operation is in progress. - 65 - CD-ROM SCSI-2 COMMAND REFERENCE MANUAL VERSION 3.1 (OB-U0077C) TABLE 2-11 PLAY AUDIO(10) (45H) Bit Byte 7 6 0 1 5 4 3 2 Operation Code (45h) Logical Unit No. Reserved 2 Starting Logical Block Address (MSB) 3 Starting Logical Block Address 4 Starting Logical Block Address 5 Starting Logical Block Address (LSB) 6 Reserved 7 Transfer Length (MSB) 8 Transfer Length (LSB) 9 Reserved - 66 - 1 0 Play Audio(10) 2.11 Play Audio(10) (45h) Operation Code is (45h). 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. - 67 - CD-ROM SCSI-2 COMMAND REFERENCE MANUAL VERSION 3.1 (OB-U0077C) TABLE 2-12 PLAY AUDIO(12) (A5H) Bit Byte 7 6 0 1 5 4 3 2 Operation Code (A5h) Logical Unit No. Reserved 2 Logical Block Address (MSB) 3 Logical Block Address 4 Logical Block Address 5 Logical Block Address (LSB) 6 Transfer Length (MSB) 7 Transfer Length 8 Transfer Length 9 Transfer Length (LSB) 10 Reserved 11 Reserved - 68 - 1 0 Play Audio(12) 2.12 Play Audio(12) (A5h) Operation Code is (A5h).

TRLBA The Track Relative Logical Block Address field specifies the two's complement starting logical block address relative to the beginning of the first sector on the track with an index value of one. Negative values indicate a starting location within the audio pause area at the beginning of the requested track. Starting Track Specifies the track number of the starting audio track. Transfer Length The Transfer Length Field specifies the number of contiguous logical blocks that shall be output as audio data. A length of zero indicates that no audio playback operation shall occur. This condition is not an error. Any other value indicates the number of logical blocks that shall be output. The PLAY AUDIO TRACK RELATIVE(10) command requests that the drive begin an audio playback operation. The starting address is specified as a track relative logical block address within the specified starting track. The command function (Immed and SOTC bits) and the output of audio signals shall be as specified by the settings of the mode parameters. If the logical block length is not equal to the sector size the drive will adjust the starting logical block address and the transfer length. The drive will start the audio play operation with the beginning of a sector whenever the starting logical address falls within that sector (MSF unit). If the requested transfer length causes the end of an audio play operation to fall within a sector the drive will continue the play operation through the end of that sector. If the starting address is not found, or if the address is not within an audio track, or if a not ready condition exists, the command is terminated with Check Condition status. - 75 - CD-ROM SCSI-2 COMMAND REFERENCE MANUAL VERSION 3.1 (OB-U0077C) TABLE 2-16 PLAY AUDIO TRACK RELATIVE(12) (A9H) Bit Byte 7 6 0 1 5 4 3 2 Operation Code(A9h) Logical Unit No. Reserved 2 Track Relative Logical Block Address (MSB) 3 Track Relative Logical Block Address 4 Track Relative Logical Block Address 5 Track Relative Logical Block Address (LSB) 6 Transfer Length (MSB) 7 Transfer Length 8 Transfer Length 9 Transfer Length (LSB) 10 Starting Track 11 Reserved - 76 - 1 0 Play Audio Track Relative(12) 2.16 Play Audio Track Relative(12) (A9h) Operation Code is (A9h).

This must be between 0 and 15. Allocation Length must include 4 byte header. This command is used with the WRITE BUFFER command to test the reliability of the drive command buffer memory and of the SCSI bus. This command does not cause a disc access. The drive terminates the DATA IN phase when it has transferred the header and data specified in Allocation Length, or the header and the remainder of the buffer. Mode field 00b 01b 10b 11b Definition The header, data, and buffer offset are 0s. The buffer offset indicates the offset from the start of the buffer at which the data are to be read. Reserved Reserved The 4-byte header and the following data are transferred to the initiator in the DATA IN phase. If Allocation Length is 0, neither the header nor data are transferred. The header is defined as follows: - Effective Length The number of bytes of valid data in the buffer. The effective length does not depend on the actual number of data written by a WRITE BUFFER command. The sum of the buffer offset plus the effective data length is always 16. The number of data to be transferred following the header is the smaller one, either the allocated length minus 4 bytes, or the effective length. When the drive cannot accept the specified buffer offset, a Check Condition is returned with the sense key "ILLEGAL REQUEST."

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.

The Start Track Field specifies the starting track number for which the data will be returned. For multi-session discs, this command will return the TOC data for all sessions. This format returns the first session number, last session number and the starting address of the last session. The Start Track field is reserved and should be set to zero. All Sub-Channel Q code information.(DRM-602X only) Reserved. The Start Track field specifies the starting track number for which the data shall be returned.

IMPLEMENTORS NOTE: The maximum TOC data length possible on currently available CDROM 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.

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 3rdParty 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. - 129 - CD-ROM SCSI-2 COMMAND REFERENCE MANUAL VERSION 3.1 (OB-U0077C) TABLE 2-33 REZERO UNIT (01H) Bit Byte 7 6 0 1 5 4 3 2 Operation Code (01h) Logical Unit No. Reserved 2 Reserved 3 Reserved 4 Reserved 5 Reserved - 130 - 1 0 Rezero Unit 2.33 Rezero Unit (01h) Operation Code is (01h).

Mode specifies meaning of the Buffer Offset field. Buffer ID is not supported. This byte must be 00h. Buffer Offset is the byte offset in the buffer where the data shall be stored. This must be 0 through 15. Transfer Length is the number of bytes to be transferred in the DATA OUT phase. This must be the data length to be sent plus 4 bytes (header size). This command is to be used with the READ BUFFER command to test the reliability of the command buffer memory in the drive, and of the SCSI bus. The drive does not access any discs. Mode 00b 01b 10b 11b Definition Header, data, and buffer offset are 0s. Buffer offset indicates the offset of the buffer at which data are to be stored. Reserved Reserved The transfer length must include the 4-byte header, therefore, the actual data length to be stored is the transfer length minus 4 bytes. As the buffer length of the drive is 16 bytes, the maximum number of bytes that can be specified for Buffer Offset is 15, and the maximum for Transfer Length is 20. If Transfer length is larger than 20, a Check Condition is returned with the sense key "ILLEGAL REQUEST." Check Condition will also be returned if the Buffer Offset + Transfer Length is larger than 20. If Buffer Offset is not 0 when Mode is 00h, Check Condition is returned.

Transfer Length is the number of bytes of CDP command data to be sent. This command sends alphanumeric Player Control commands to the drive. The drive returns the command status after the player control command is transferred to the drive controller chip. A GOOD status indicates only that the command was syntactically correct. The READ CDP command must be used to determine the results of the operation. (See Appendices A and B for details on audio functions.) The Player Control command data can contain up to 21 characters including a Carriage Return (0Dh). If Transfer Length is larger than 21, Check Condition is returned with sense key ILLEGAL REQUEST and sense code 24h, "Invalid Command Block Other Than 20 or 21". IMPORTANT: THE COMMAND STRING MUST BE TERMINATED WITH A CARRIAGE RETURN Data after a Carriage Return is ignored. When there is no Carriage Return, Check Condition is returned with sense key ILLEGAL REQUEST, sense code "Error in Parameter List" (26h).

Operation Code is (D8h). The READ CD-DA command requests that the drive transfer CD-DA data and/or Sub Code data. The Starting Logical Block Address specifies the block where the READ operation begins. The definition of the starting logical block address is as follows: Starting Logical Block Address = (M-Ms) * 60 * 75 + (S-Ss) * 75 + (F-Fs) (M, S, F) = absolute MSF address of the requested starting logical block (Ms, Ss, Fs) = absolute MSF address of the first block of the first track Sub Code Field: Sub Code Field CD-DA block length 00h 2352 bytes CD-DA data with no Sub Code 01h 2368 bytes CD-DA data with Sub Q Code 02h 2448 bytes CD-DA data with all Sub Code 03h 96 bytes 04 ~ FFh Description All Sub Code only Reserved If the Sub Code field is set to 00h, the drive returns the CD-DA data without Sub Code data. (Each block consists of 2352 bytes of digital audio data without any Sub Code data.) If the Sub Code field is set to 01h, the drive returns the CD-DA data with Sub Q data. Each block consists of 2368 bytes which includes 2352 bytes of digital audio data, 10 bytes of Sub Q data and 6 bytes of zeros. Note: 16 bits of CRC for the Sub Q data are not transferred. If the Sub Code field is set to 02h, the drive returns the CD-DA data with all Sub Code data. (Each block consists of 2448 bytes which includes 2358 bytes of digital audio data and 96 bytes of Sub Code data.) If the Sub Code field is set to 03h, the drive returns 96 bytes of all Sub Code data only. The Transfer Length specifies the number of contiguous CD-DA data blocks to be transferred. - 157 - CD-ROM SCSI-2 COMMAND REFERENCE 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. - 158 - Read CD-DA (this page has been left intentionally blank) - 159 - CD-ROM SCSI-2 COMMAND REFERENCE MANUAL VERSION 3.1 (OB-U0077C) TABLE 2-47 READ CD-DA MSF (D9H) Bit Byte 7 6 0 1 5 4 3 2 Operation Code (D9h) Logical Unit No. Reserved 2 Reserved 3 Starting M Field 4 Starting S Field 5 Starting F Field 6 Reserved 7 Ending M Field 8 Ending S Field 9 Ending F Field 10 Sub Code 11 Reserved - 160 - 1 0 Read CD-DA MSF 2.47 Read CD-DA MSF (D9h) 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. - 165 - 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.
