4.2 SCSI Bus 4.2.1 System configuration (1) System configuration The SCSI bus connects up to eight SCSI devices, each linked with a daisy chain. The both ends of the daisy chain require a terminator. Each SCSI device operates as an initiator or a target, so that a series of operations are performed between a pair of initiator and target pair. The system may be configured with any combination of initiators and targets as long as the number of the initiators and targets combined does not exceed eight.
4.2.2 Bus signals Initiator Signal name Type of signal Target Data DB0 DB1 DB2 DB3 DB4 DB5 DB6 DB7 (Data Bus n) DBP (Data Bus Parity) Control BSY signals (Busy) Eight data>bit signals, plus a parity>bit signal that form a DATA BUS. DB(7) is the most significant bit and has the highest priority during the ARBITRATION phase. Bit number, significance, and priority decrease downward to DB(0). A data bit is defined as one when the signal value is true.
4.2.3 Bus signal drive conditions SCSI devices drive signals of the SCSI bus. The types of SCSI devices are summarized in the following table, showing the signals that they can drive for each operating phase of the interface. There are two kinds of signal driving methods, OR tied and NON>OR tied, as shown in Table 4.2. During an interface operating sequence, the BSY signal could be driven simultaneously by two or more SCSI units when the data bus is in the ARBITRATION or RESELECTION phase.
Table 4.2 Bus phases vs. signal drive sources (2/2) ID: A unique data bit (the SCSI ID) shall be driven by each SCSI device that is actively arbitrating. The other seven data bits shall be released (shall not driven) by this SCSI device. The parity bit (DB(P)) may be released or driven to the true state, but shall never be driven to the false state during this phase. I&T: The initiator and target drive the signal according to the interface operating sequence.
Reset MESSAGE OUT SELECTION COMMAND BUS FREE ARBITRATION DATA IN or DATA OUT STATUS RESELECTION MESSAGE IN Figure 4.2 Phase sequence The signal delay times for each bus phase are defined as follows: Table 4.4 Signal delay times definition (1/3) No. Item Time Definition 1 Arbitration delay 2.4 os The minimum time an SCSI device shall wait from asserting BSY for arbitration until the DATA BUS can be examined to see if arbitration has been won. There is no maximum time.
Table 4.4 Signal delay times definition (2/3) No. Item Time Definition 4 Bus free delay 800 ns The minimum time that an SCSI device shall wait from its detection of the BUS FREE phase (BSY and SEL both false for a bus settle delay) until its assertion of BSY when going to the ARBITRATION phase 5 Bus set delay 1.
Table 4.4 Signal delay times definition (3/3) No.
4.3.2 ARBITRATION phase The ARBITRATION phase allows one SCSI device to gain control of the SCSI bus so that it can initiate or resume an I/O process. The procedure for an SCSI device to obtain control of the SCSI bus is as follows: — The SCSI device shall first wait for the BUS FREE phase to occur. “ The SCSI device shall wait a minimum of a bus free delay after detection of the BUS FREE phase (i.e. after the BSY and SEL signals are both false for a bus settle delay) before driving any signal.
ARBITRATION phase bus settle delay bus free delay BSY SCSI SEL DB BSY ID7 bus set delay arbitration delay bus clear delay + bus settle delay & bus free delay SEL DB(7) bus clear delay bus set delay & BSY bus free delay ID3 SEL DB (3) arbitration delay BSY & ID1 bus free delay SEL DB (1) 4 $ 14 ID7: Succeeds in ARBITRATION ID3: Detects the SEL signal of other SCSI unit ID1: Detects the SCSI ID with higher priority than itself &: The point at which the BUS FREE phase is detected b
4.3.3 SELECTION phase The SELECTION phase allows an initiator to select a target for the purpose of initiating some target function (e.g., READ or WRITE command). During the SELECTION phase the I/O signal is negated so that this phase can be distinguished from the RESELECTION phase. — The SCSI device that won the arbitration has both the BSY and SEL signals asserted and has delayed at least a bus clear delay plus a bus settle delay before ending the ARBITRATION phase.
4.3.4 RESELECTION phase RESELECTION is an optional phase that allows a target to reconnect to an initiator for the purpose of continuing some operation that was previously started by the initiator but was suspended by the target (i.e., the target disconnected by allowing a BUS FREE phase to occur before the operation was complete). — Upon completing the ARBITRATION phase, the winning SCSI device has both the BSY and SEL signals asserted and has delayd at least a bus clear delay plus a bus settle delay.
4.3.5 INFORMATION TRANSFER phases Note: The COMMAND, DATA, STATUS, and MESSAGE phases are all grouped together as the information transfer phases because they are all used to transfer data or control information via the DATA BUS. The actual content of the information is beyond the scope of this section. The C/D, I/O, and MSG signals are used to distinguish between the different information transfer phases (see Table 4.5).
INFORMATION INFORMATION TRANSFER phase bus settle delay Min. 0ns TRANSFER phase bus settle delay BSY SEL C/D, MSG, I/O REQ ACK DB The INFORMATION TRANSFER phases use one or more REQ/ACK handshakes to control the information transfer. Each REQ/ACK handshake allows the transfer of one byte of information. During the INFORMATION TRANSFER phases the BSY signal shall remain true and the SEL signal shall remain false.
After the ACK signal is false, the target may continue the transfer by driving the DB(7>0, P) signals and asserting the REQ signal, as previously described. bus settle delay deskew delay + cable skew delay deskew delay + cable skew delay BSY SEL C/D, MSG I/O REQ ACK DB b. Asynchronous transfer from initiator to target If the I/O signal is false (transfer to the target), the target shall request information by asserting the REQ signal.
bus settle delay deskew delay + cable skew delay deskew delay + cable skew delay BSY SEL C/D, MSG I/O REQ ACK DB 4.4 Commands Commands are directions issued from an initiator to a target.

4.6 Messages This section describes the detection of an ATN signal and explains the types of messages supported by this scanner. 4.6.1 ATN detection The following table summarizes the timing at which this scanner detects an ATN signal.
Code 00 COMMAND COMPLETE 05 INITIATOR DETECTED ERROR 06 ABORT 07 MESSAGE REJECT 08 NO OPERATION 09 MESSAGE PARITY ERROR 0C BUS DEVICE RESET 80 to FF (1) Message IDENTIFY 04 DISCONNECT 02 SAVED DATA POINTER 03 RESTORE POINTERS COMMAND COMPLETE (X©00π) : MESSAGE IN phase (target Æ initiator) This message indicates that a command has been terminated and a valid status has been reported to the initiator.
When this scanner receives the INITIATOR DETECTED ERROR message, this scanner enters the MESSAGE IN phase and sends the RESTORE POINTERS message to the initiator. Then this scanner returns to the original phase and makes a retry. After issuing the RESTORE POINTERS message, this scanner takes action as shown in the following table.
This scanner does not have a function that clears input/output operation for certain initiators. The scanner must have been reserved when it is operated in multi> initiator environment. (4) MESSAGE REJECT (X©07) : MESSAGE IN/OUT phase (initiator Æ target) This message indicates that a transferred message was rejected by the receiver as invalid or unexecutable. The initiator does not intend to issue another message by activating ATN before it deactivates the ACK of the MESSAGE REJECT message.
(6) MESSAGE PARITY ERROR (X©09π) : MESSAGE OUT phase (initiator Æ target) This message indicates that the initiator detected a parity error in the message received. The target resends only that message. The initiator does not intend to issue another message by activating ATN before it deactivates the ACK of the MESSAGE PARITY ERROR message. Upon receiving the MESSAGE PARITY ERROR message, this scanner takes action as shown in the following table.

D.1 Enhanced Functions and Functional Differences This section explains the functions added to M3096G image scanners and the functional differences between M3096G and M3097G image scanners. This is useful when installing M3097G image scanners. Table D.1.1 lists the added functions. Table D.1.1 Added functions Section to be referenced Remarks The paper size detection function is added for an automatic document feeder (ADF).
Functions added D.1.1.1 Paper size detection f f Restrictions - This function is operable only when using ADF. If this function is used for flat bed (FB) reading, the results from the scanner are not guaranteed. - If paper listed in OEM Manual Appendix A.3 is used, the results from the scanner are not guaranteed. - The applicable paper sizes are DL or A3, Lt or A4, A5, B4, and B5. The scanner cannot distinguish DL from A3, or LT from A4.
f Description - Upon receiving the detected paper information from the read command (Data type code = Xπ81π), the driver or application software must specify the window area (Set window command Byte 6 to 15) and the paper size (Set window command Vender unique parameter byte 35) using the set window command. - The detected paper information is accessed with the read command (Data type code = Xπ81π).
D.1.1.2 Job separation sheet detection f Notes on using this function f - This function must be used to separate different jobs. - For the sheet format, refer to OEM Manual Appendix A.5. Restrictions f - The sheet format must be in accordance with OEM Manual Appendix A.5. - The sheet quality must be in accordance with OEM Manual Appendix A.2.
