3 Host adapter Controller Host adapter PDTS1C34D002-A01 System Configuration The product performs the action specified input from the host adapter acts as initiator. System configuration example. Initiator Target Host computer HFD35C-xxxGT SCSI Device SCSI Device Initiator Target Host computer Logical Unit SCSI Device SCSI Device To other SCSI Device SCSI Bus Configuration SCSI bus for up to eight SCSI devices can be connected. I/O Device addressing A specific device number (SCSI-ID) is assigned to each of SCSI devices. A device for input and output operations, which is on a SCSI device operating as a target or linked to the device, is accessed in units referred to as logical units, and each has its specific device number (LUN: logical unit number) assigned. An initiator designates SCSI-ID to select a single SCSI device operating as a target device, then designates LUN to select a device on the target device or linked thereto for an input and output operation. SCSI-ID and LUN are selectable within the following ranges. SCSI-ID: selectable within the range of #0 to #7 (select by the DIP switch on the conversion adaptor) LUN: #0 fixed /56

10 Signals Name SCSI bus signals Signal Name Dir. Pin# Description -BSY I/O 36 It is busy signal. When using the bus, it asserts. When the other target has used the bus, it is asserted. -SEL I/O 44 It is the selection signal. It uses when it selects the target with the initiator. It uses when reselect the initiator with the target. -C/D O 46 It is the control/data signal. In order to display control on the data bus or data information, although it uses. The truth is control. -I/O O 50 It is the input/output signal. It controls direction of the data bus with the initiator. The input is control. -MSG O 42 It is message signal. It uses with message phase. -REQ O 48 It is request signal. It uses to request as a handshake of the information transfer of -ACK. -ACK I 38 It is the acknowledging signal. It uses to the approval with the initiator as a handshake of the information transfer of -REQ. -ATN I 32 It is the attention signal. The initiator is used in attention state. -RST I 40 It is the reset signal. Hard reset When this signal is asserted above 800ns This product is not to act as the initiator, this device may not be for-rst signal, Reset signal Dir is I. (Dir is not I/O.) -DB7-0 I/O It is the data bus signal of 8 width. -DB7 is highest and -DB0 is 16, 14, 12, 10, 8, 6, 4, 2 lowest. It uses for SCSI-ID indicate too. -DBP I/O 18 It is odd parity data bus signal. TERMPWR I 26 It is line for terminator. It is supplied from host side. GND - 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 20, 21, 22, 29, 30, 31, 33, 34, Ground. 35, 37, 39, 41, 43, 45, 47, 49 OPEN - 23, 24, 25, 27, 28 No use. It is opened state.

11 SCSI Bus phase BUS FREE phase Bus free phase is in a state where every SCSI device has not used the bus. When -BSY signal and - SEL signal both are under false, it becomes bus free. It will be bus free after reset of initial state and after SCSI device released ARBITRATION phase Arration phase allows that SCSI device get control SCSI bus. SCSI device asserts BSY signal and SCSI-ID (Data bus) when bus free. However, when initiator does not support resection, initiator will win. The won device asserts SEL signal, lose device will release BSY signal and SCSI-ID. Then sift selection phase and reselection phase. It can omit when system component is single initiator. SELECTION phase SCSI device become initiator in arration phase which is selected target in selection phase. It doesn t assert I/O signal during selection phase. Initiator set own SCSI-ID and target SCSI-ID on data but and asserts ATN signal. Initiator waits response from target after release BSY signal. Target checks SEL signal and own SCSI-ID is true and BSY and I/O signal is false. Specified target asserts BSY signal. Then sift Information transfer phases. In case of no-response from target, go process to section time out phase. <SECTION time out> Section time out process supports 2 types. Initiator-RST to generate a reset condition by asserting the signal. There is no response from the target signal-bsy, when you move to the bus free phase. RESELECTION phase Reselection phase select initiator after became target device which won at arration phase. I/O signal is asserted in reselection phase. Won SCSI device asserts BSY signal and SEL signal. The device set own SCSI-ID and initiator s SCSI-ID on data bus. Target release BSY signal. Initiator checks SEL and I/O signal is true and BSY signal reselected as false. Reselected initiator checks reselected target of SCSI-ID. Reselected initiator asserts BSY signal. Target checks BSY signal is true. And Target asserts BSY signal and releases SEL signal. Target exchange I/O signal and data bus. Reselected initiator checks SEL signal is false and release BSY signal. It continues asserting till hand over SCSI bus. Then go information transfer phases. When it doesn t response from initiator, go selection time out process. <RESECTION time out> Section time out process supports 2 types. Target -RST to generate a reset condition by asserting the signal. There is no response from the Initiator signal-bsy, when you move to the bus free phase. * The initiator is not to be a product; the product (target) to generate a reset condition is not available. Information transfer phases With using -C/D, -I/O and MSG signal discriminate deference information transfer phases. Target control each information transfer and phases. With using the 3 of signal. Initiator asserts ATN signal and request massage out phase. Target release MSG, -C/D, -I/O and BSY signal and go bus free phase. Information transfer phase uses hand shake of REQ/ACK to control information transfer. Each REQ/ACK of hand shake allows 1byte information transfer. BSY signal is true and SEL signal is false during the phase. -MSG -C/D -I/O Phase name Direction of transfer Asynchronous Synchronous F F F DATA OUT Initiator Target F F T DATA IN Initiator Target F T F COMMAND Initiator Target F T T STATUS Initiator Target T F F Reserved T F T Reserved T T F MESSAGE OUT Initiator Target T T T MESSAGE IN Initiator Target F: False(Negate), T: True(Assert) /56

12 COMMAND phase Command phase allows with target if initiator require command information. Target asserts C/D signal and negates -I/O signal and MSG signal for hand shake of REQ/ACK. DATA IN phase Data in phase allows with target if require to send date from target to initiator. Handshake between the target -REQ/ACK,-I/O signal is asserted,-c/d and -MSG signal is negated. DATA OUT phase Data out phase allows with target if require to send date from target to initiator. Handshake between the target -REQ/ACK,-C/D,-I/O and -MSG signal is negated. STATUS phase Status phase allows with target if require to send date from target to initiator. Handshake between the targets -REQ/ACK,-C/D and-i/o signal is asserted,-msg signal is negated. MESSAGE IN phase Massage in phase allows with target if require to send date from target to initiator. Handshake between the target -REQ/ACK,-C/D,-I/O and -MSG signal is asserted. MESSAGE OUT phase Massage out phase allows with target if it request from initiator to target. Target calls attention to this phase depending on the state created by the initiator. Handshake between the targets -REQ/ACK,-C/D and-msg signal is asserted,-i/o signal to negate. Target unless you reject the message,-atn signal is negated until the conduct handshake phase, the target receives the message.

15 3. UNIT ATTENTION CONDITION Immediately after the power of the drive in this series is turned on or immediately after a reset according to the SCSI RESET and BUS DEVICE RESET messages, (POWER ON, RESET, OR BUS DEVICE RESET OCCURRED) is retained as error information at each initiator until the retention is cancelled by a command from the initiator. Response to commands in UNIT ATTENTION CONDITION and cancellation of the retention status are performed according to the following conditions. (1) The INQUIRY (12h) command is executed normally. The retention of UNIT ATTENTION CONDITION is not cancelled. (2) The REQUEST SENSE (03h) command is executed normally. As sense data transferred to the initiator, sense data that has generated UNIT ATTENTION CONDITION is returned. The retention of UNIT ATTENTION CONDITION is cancelled. (3) Commands other than those described above return the CHECK CONDITION status and cancel the retention of UNIT ATTENTION CONDITION. At this time, since UNIT ATTENTION=06h is written in a sense key in the sense data, the initiator can determine the cause of generation of UNIT ATTENTION CONDITION from the sense data by issuing the REQUEST SENSE command. 4. SENSE DATA The drive in this series generates sense data in the following cases. (1) When the CHECK CONDITION status is returned during execution of the SCSI command. (2) When UNIT ATTENTION CONDITION is generated. Generated sense data is retained for the initiator that has issued the SCSI command. The retention of the sense data is cancelled in the following cases. (1) The retention of the sense data is cancelled when the initiator issues a new SCSI command. If the new command is the REQUEST SENSE (03h), the sense data being retained is transferred. (2) A command from an initiator other than the one for which the sense data is retained is accepted normally. (3) If RESET CONDITION occurs on a SCSI bus, or if an arrary initiator issues the Bus Device Reset message, UNIT ATTENTION CONDITION is generated, the sense data that has generated UNIT ATTENTION CONDITION is retained, and the previously retained sense data is lost. * When the error code written in the text, if otherwise specified, Sense Key, ASC, ASCQ conventions are represented in order, separated by hyphens. Example) Sense Key = 05h, ASC = 24h, ASCQ = 00h: /56
