GENERAL DESCRIPTION AND APPLICATION DATA
1.1 GENERAL DESCRIPTION
The Kennedy Model 9600A (Figure 1-1) is a rack mount, automatic load, tape drive that
includes an embedded Formatter capable of communicating between an industry standard
interface bus and ANSI- and IBM-compatible PE 1600 BPI, PE 3200 BPI and NRZI 800
BPI tapes. The drive can operate in streaming or start/stop mode and can read in either
forward or reverse direction.
1.1.1 FEATURES
The Kennedy Model 9600A features:
1. Two independent microprocessors: one for the drive servo electronics: one for the
Formatter.
2. Tru 50-ips Start/Stop Mode with standard 0.6-inch gaps.
3. 100-ips
streaming mode provides high speed data tranSfers for backup needs.
4. Low profile height saves rack space.
5. Modular configuration that allows for future expansion.
6. Self diagnostic
capability.
7. Front-panel eight-character LED readout that displays operational status, errors,
abnormalities, and diagnostic parameters.
1.1.2 HOST INTERFACE
The 9600A Drive has the Industry Standard Interface for Formatted 1/2-inch Tape Drives.
1.1.3 MICROCOMPUTER BASED DESIGN
The 9600A uses two 8051 bit-mapped microprocessors: one in the Formatter, and one in
the Drive Control Electronics.
1.1.4 DIAGNOSTICS AND FAULT ISOLATION
The 9600A includes built-in diagnostics with front-panel eight-character LED readout for
fault isolation.

1.6.1.2 INrrIATE COMMAND
IGO
Pulse PI-8
The IGO pulse initiates any command specified by the command lines described in the
following paragraphs. Information on the command lines is latched by the Formatter on
the trailing edge of the IGO pulse. IFBY is set true now) when the IGO pulse is given to
the Formatter and the selected Drive is ready.
NOTE: Command lines must be stable
0.5 microsecon<E before and after the IGO pulse.
1.6.1.3 REVERSE/FOR
WARD IREV
Level
PI-I8
The IREV level initiates reverse tape
motion when true
now). When false (high),
this level
specifies forward tape motion.
1.6.1.4 WRITE/READ IWRT Level PI-34
Write mode is specified when IWRT is true now); read mode is specified when IWRT is
false (high).
1.6.1.5 WRITE FILE MARK
IWFM Level
PI-42
The Formatter will write a file mark on tape when both IWFM and IWRT are true -now).
1.6.1.6 EDIT IEDIT Level
PI-38
When both IEDIT and IWRT are true now), the Drive operates in the edit mode. Both
IEDIT and IREV
true Qow) modify the read reverse stop delay to optimize head
positioning for a subsequent edit operation.
1.6.1.7 ERASE IERS Level
PI-40
When IERS, IWRT, and IWFM are all true Qow), approximately 3.75 inches of tape will be
erased. Both IERS and IWRT true Qow) will cause the Formatter to execute a dummy
write command; the Formatter will issue a normal write command but no data will be
recorded. A length of tape, as defined by IL WD, will be erased.
1-9

General Description
93-9600-998
1.6.1.8 mGH SPEED IHSP Level
P2-50
IHSP true (low) causes the selected on-line Drive to operate in high speed mode (100 ips).
1.6.1.9 REWIND
IREW Pulse
Pl-20
A pulse which causes the Drive to rewind to load point. IREW pulse is directly routed to
the Drive and does not cause the Formatter to go busy.
1.6.1.10 LONG GAP ILGP Level
Pl-44
ILGP true (low), during a write mode, causes gaps of 1.2 inches to be erased on tape
between data blocks instead of the normal 0.6 inch gaps.
1.6.1.11 OFF-LINE/UNLOAD
IOFL Pulse
P2-24
Asserting the IOFL pulse causes the Drive to rewind to load point, go off-line, and unload
the tape onto the supply reel.
1.6.1.12 LAST WORn ILWD
Level Pl-4
IL WD goes true (low) when the last data character is placed on the interface lines. IL WD
true (low) during a write or erase command indicates that the next character to be
strobed into the Formatter is the last character of the record.
1.6.1.13 FORMATTER ENABLE IFEN Level
P2-18
IFEN false (high) causes all formatters in the system to revert to the quiescent state.
The IFEN signal line may be used to: 1) disable the formatters if Host power is lost or
2) clear Formatter logic when illegal commands or unusual conditions occur.
1.6.1.14 WRITE DATA LINES IWP, IWO-IW7 Levels (Table 1-3)
Write Data lines are used in all densities.
The nine Write
Data lines transmit write data from the Host to the Formatter. The data
bits appearing on IWO-IW7 are written onto the corresponding channels on tape; IW7
corresponds to the least significant bit of the character.
The IWP line is optional and is utilized only if it is required to check the parity bit
specified by the customer. The Formatter generates odd parity internally on the basis of
data contained on IWO-IW7.
The first character of a record should be available on these lines within one character
period after IDBY goes true (low) and remain until the trailing edge of the first IWSTR is
issued by
the Formatter. The next character of information must then be placed on these
lines within one half of a character period. Subsequent characters of a record are
processed in this manner until IL WD is set true (low) by the Host when the last character
is transmitted.
1-10

93-9600-998 General Description
1.6.1.15 LOAD ON LINE ILOL Pulse PI-I6
'ILOL causes the Drive to be placed on line. If the Drive had been rWlning when it went
off line, but was not in Rewind, the tape retensions and positions past the point when
ILOL was asserted. If the tape is installed but not yet loaded when ILOL is asserted, the
tape loads and rewinds to BOT.
1.6.2 INTERFACE OUTPUT SIGNALS (DRIVE TO HOST)
1.6.2.1 FORMA'ITER BUSY IFBY Level
PI-2
IFBY goes true Qow) on the trailing edge of IGO when a command is issued by the Host.
IFBY will remain true until tape motion ceases.
1.6.2.2 DATA BUSY IDBY Level P2-38
IDBY goes true Qow) during the active execution of all command; initiated by IGO. A
new command may be issued 0.5 microseconds
after IDBY goes false (high).
1.6.2.3 HARD ERROR
IHER Pulse P2-I2
NRZI Mode:
IHER
true Qow) indicates a read error. IHER line will be true Qow) during read operation
when one or more of the following occurs:
1. Longitudinal parity error.
4. Vertical parity error on a data character.
2. Improper record format.
5. Read After Write Compare Error.
3. CRCC parity error.
6. Write Data Parity Error (optional).
In all cases except a vertical parity error, IHER will be pulsed after the complete record
has been read. In the case of a vertical parity error, the IHER line will be pulsed when a
read strobe (RSTR) pulse is issued for the character in error. IDBY goes false (high) after
all error information has been transferred to the Host.
PE Mode (1600 and 3200 BPD:
IHER true Qow) indicates that an uncorrectable read error has occurred and that the
record should either be reread or rewritten. The table below illustrates the possible
IHER/ICER signal combinations:

General Description
93-9600-998
1.6.2.4 CORRECTED BRROR ICER Pulse P2-42
ICER
true (low) indicates that a single track dropout has been detected and the
Formatter is performing an error correction.
1.6.2.5 CHECK CHARACTER GATE AND IDENTIFICATION BURST
ICCG/ID Level P2-16
Check Character Gate: In NRZI Read Mode, the Formatter sets ICCG true (low) when
the Formatter sends to the Host a Cyclic RedWldancy Check Character (CRCC) or a
Longitudinal RedWldancy
Check Character (LRCC). When the Formatter sends data to the
Host, it resets ICCG false (high). After the tape leaves load point, the ICCG/ID line
should be used only when the Drive is in NRZI mode.
ID Burst: In PE 1600 and 3200 Read Mode, the Formatter sets ID true (low), indicating
the ID Burst has been detected and identifying the tape in the Drive as a PE 1600 or
3200 Tape.
1.6.2.6 FILE MARK IFMK Pulse P2-14
IFMK is pulsed when a file mark is detected on the tape during a read operation or
during a write file mark operation in a rea~after-write operation. The IFMK line will be
pulsed
after a complete file mark record has been read. Error conditions should be
ignored when a file mark is detected.
1.6.2.7 ON-LINE IONL Level P2-44
IONL is
true (low) when the on-line fli{rflop is set, indicating the Drive is Wlder remote
control. IONL false (high) indicates the Drive is Wlder local control.
1.6.2.8 READY IRDY Level P2-28
IRDY is true Uow) only when the Drive is ready to receive external commands; the
following conditions must exist:
1. All interlocks are made.
2. Initial load or rewind sequence is complete.
3. Drive is on-line.
1.6.2.9 FILE PROTECT IFPT Level P2-32
IFPT is true (low) when a reel of tape without a write-enable ring is mounted on the
Drive supply hub.
1.6.2.10 LOAD POINT ILDP Level P2-4
ILDP is
true (low) when the load point marker is mder the BOT sensor and the Drive is
not rewinding. After receipt of a motion command the signal will remain true until the
load point marker leaves the BOT sensor area.
1-12

93-9600-998 General
Description
1.6.2.11 END OF TAPE IEOT Level P2-22
IEOT is true Uow) when the EOT marker is detected in the forward direction. mOT goes
false (high) when the EOT marker is detected in reverse (REWIND).
1.6.2.12 REWINDING
IRWD Level P2-30
IRWD is true Uow) when the Drive is engaged in a rewind operation or returning to the
load point at the end of the rewind operation.
1.6.2.13 WRITE STROBE IWSTR Pulse P2-36
IWSTR pulses each time a data character is written onto tape. IWSTR samples the write
data lines IWP, IWO-IW7 from the Host and copies this information character by character
into the Formatter logic. The first character should be available prior to the first write
strobe pulse and succeeding characters should be set up within half a character period
after the trailing edge of each write strobe pulse. The write strobe is also active during
variable length erase command; however, the data being copied into the Formatter will
have no meaning.
1.6.2.14 READ STROBE IRSTR Pulse P2-34
IR:3TR is pulsed for each character of read information to be transmitted to the Host.
IRSTR is used to sample the read data lines IRP and IRDO-IRD7.
In NRZI formatters, the transmission of CRC and LRC data characters will be flagged by
the check character gate (ICCG) signal as described above under IHER.
1.6.2.15 READ DATA LINES IRP, IRO-IR7 Levels (Table 1-3)
The
read data lines transmit the read data for NRZl, and PE 1600 and 3200 modes. Each
character read from tape is made available by parallel sampling the read lines using the
Read Strobe. Since the data remains on the read lines for a full character period, the
corresponding IRSTR pulses are timed to occur after approximately the center of the
character period.
1.6.2.16 SPEED ISPD Level P2-40
!SP D
true Uow) indicates the selected Drive is in the high speed streaming mode.
1.6.2.17 NRZI INRZI Level P2-26
INRZI true Uow) indicates the selected Drive is operating in NRZI mode. A false (high)
level on INRZI indicates the selected Drive is operating in the PE 1600 or 3200 mode.

Data
1.6.3.1 READ FORWARD
READ FOR WARD command causes tape on the selected Drive to be accelerated to the
normal Drive operating speed. The Drive generates the delays necessary for proper
positioning of the Drive read head in the interblock gap. Another read command can be
issued before the tape decelerates to a stop, reducing the access time by at least one
ramp time.
1.6.3.2 READ REVERSE AND READ REVERSE EDIT
Read Reverse command is similar to a Read Forward command except that tape motion
is in the reverse direction. During the reverse operation, the unit always resets to the
quiescent state when the BOT signal is present. In this operation the head can be
repositioned further back in the gap by issuing the Edit command, to optimize head
positioning for rewriting the block.
1.6.3.3 WRITE
Write command causes the unit to accelerate tape, and after the appropriate prerecord
delay time, to begin transfering data from the Host to the Drive. This process continues
lDltil a Last Word input is recei ved from the Host.
