Description
1.3 INTERFACE flJECIFICATIONS
1.3.1 GENERAL
This section describes the signal requirements and characteristics of the interface
between the tape drive and the controller. The connectors and cable requirements are
described, as well as the actual lines and the com mands derived from the lines. The
interface lines are sum m arized in Tables 1-4A and 1-4B while the com mand structure
is summarized in Table 1-5.
1.3.2 INTERFACE CONNECTORS
The interface connectors on the Model 9600B/9650B are designed for standard fifty line
shielded cables. For each active connector pin there is an associated ground pin. The
mating
interface connectors are two 50~in card cage connectors.
1.3.3 INTERFACE SIGNAL CHARACTERISTICS
Signals from the controller to the Model 9600B/9650B must conform to the following
specifications:
Levels: 1 = Low = True = OV (+0.7 Vdc) NOTE:
o = High = False = +3V (+/-0.5 Vdc) Total edge transmission
Pulses: 1 = Low =
True = OV (+0.7 Vdc) Delay =<200 nanosec over
o = High = False = +3V (+/-0.5 Vdc) a 20-foot cable.
All output signals from the Model 9600B/9650B are driven by open collector type line
drivers capable of sinking up to 36 rnA (25 standard unit loads) in the low true state.
Open lines will result in false signal levels.
1.3.4 INTERFACE CABLES
Per FCC and ESD specs, interface cables should be braided and shielded with maximum
allowable
length of 20 feet.
1.3.5 RECEIVER/DRIVER CONFIGURATION AND TERMINATION
The input lines to the transport are terminated with a 220 ohm resistor to plus five
volts, and a 330 ohm
resistor to ground (Figure 1-2). All input circuits have low level
input voltage of 0.7 V maximum and a high level input voltage of 2.0 V minimum. The
input
receivers are all 74LS type circuits.
All output lines must be terminated at the far end of the daisy chained cable with a
220 ohm resistor to plus five volts and a 330 ohm resistor to ground. Output circuits
are 7438 open collector drivers as shown in Figure 1-2•

1.4.1.2 INITIATE COMMAND - GO
GO
Pulse
General Description
PI-3
A pulse which initiates any command specified by the command lines described in the
following paragraphs. Information on the command lines is copied into the unit on the
trailing edge of the GO pulse. At the end of the reinstruct window in streaming write
commands only, it is possible for the Host to extend the reinstruct window by
asserting and holding the GO pulse in a true state. The unit will continue to stream
for up to one inch waiting for the trailing edge of the GO pulse as the Host returns
GO to the false state. If one inch is exceeded and the GO pulse has yet to be
denied, the unit shall enter a reposition cycle. This feature in effect creates extended
gaps.

mode (100 ips).
1-9

General Description
93-09600-994
1.4.1.9 LONG GAP
LGP
Level
PI-36
When true during a Write Mode, this level causes the generation of a longer
Interrecord Gap (erased area on tape) to allow ample reinstruct periods as required for
Host system
latencies. Long Gap Time is limited by its setting in Setup Options, but
terminates automatically if a Write Command is received before the selected limit.
1.4.1.10 REWIND
REW
Pulse
P1-20
A pulse which causes the selected transport to rewind to load point. This pulse does
not cause the formatter to go busy. The Ready status will remain false during rewind.
In daisy chained systems, the rewind pulse can be issued to one or more of the units
in the chain while allowing data transfer operations to occur on any other unit in the
chain.
1.4.1.11 OFF LINE/UNLOAD
OFL Pulse
P2-24
This pulse causes the transport to go off line im mediately, then rewind to load point
and unload
the tape.
1.4.1.12 LAST WORD
LWD
Level
P1-4
When this level is true during a write or variable erase com mand, it indicates that the
next character to be strobed into the form atter is the last character of the record.
LWD should go true when the last data character is placed on the interface lines.
1.4.1.13 FORMATTER ENABLE
FEN Level
P2-18
When false this level causes all units in a daisy chain configuration to revert to the
quiescent state. This line may be used to disable the units if controller power is lost
or to clear unit logic when illegal commands or unusual conditions occur. When denied
during command execution, the unit will abort the command in an orderly fashion and
stop motion. The unit
Set Up options (described in Operation and Maintenance Manual)
allows
the polarity of this level to be selected.
1.4.1.14 WRITE DATA LINES
WP,
WO-W7 Level
These 9 lines transmit write data from the controller to the formatter. The 8 data
bits appearing on W O-W 7 are written onto the corresponding channels on tape; W7
corresponds
to the least significant bit of the character. Line WP is optional and is
utilized only
if it is required to check the parity bit generated by the customer. The
formatter generates odd parity internally on the basis of data contained on W O-W 7.
1-10

93-09600-994 General Description
The first character of a record should be available on these lines within one character
period after DB Y goes true and remain until the trailing edge of the first W STR is
issued by
the unit. 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 LW D is set true by the controller when the last
character is transmitted.

1.4.2 INTERFACE OU'IPUTS (96008/96508 to host)
1.4.2.1 FORMATTER BUSY
FBY Level
PI-2
This level goes true on the trailing edge of GO when a command is issued by the
controller. FBY will remain true until tape motion ceases or optionally until DBY goes
false on 100 ips commands. The unit Setup options (described in Operation and
Maintenance Manual) allow selection of the cancellation point for FBY.
1.4.2.2 DATA BUSY
DBY
Level P2-38
This level goes true during the active execution of all commands initiated by GO. A
new command may be issued after DBY goes false.
1.4.2.3 HARD ERROR (All DENsrrmS)
HER
Pulse P2-12
When true, this pulse indicates one or more of the following error conditions has
occurred. The following
list sum marizes the errors for all three densities.
1-11

General Description 93-09600-994
NOTE: The HER may be reported as a real time pulse for each error condition as it
occurs; or the occurrence of at least one HER or CER within the block can be
captured by the Host before the falling edge of DB Y at the end of the data block.
a. Longitudinal parity error.
b. Improper record format.
c. CRCC parity error.
d. Vertical parity error on a data character.
e. Host write parity error (optional).
f. No file mark detected in Read After Write mode when executing a Write File
Mark command.
g. If a gap of 25 feet is detected while executing a Read Block, Space Block or
Search File Mark command (optional).
h. Read after Write compare error.
i. Excessive skew.
j. Postamble error.
k. Multiple channel error.
1. CRC error.
1.4.2.4 CORRECTED ERROR (PE, DDPE MODE)
CER Pulse P2-42
This pulse indicates that a single track dropout. has been detected during read or write
and the unit will perform a vertical parity correction.
1.4.2.5 CHECK CHARACTER GATE (NRZI MODE ONLY)
ID/CCG Level P2-16
This level is set true by the unit when the read information being transmitted to the
controller is the cyclic redundancy check character (CRCC) or the longitudinal
redundancy check character (LRCC) of the data block. When data characters are
transmitted, CCG goes false. Data and Check information can be distinguished by
gating Read Strobe with CCG or its inverse. After leaving load point this line should
only be used during NRZI mode.
NOTE: CCG and
the Read Strobes (RSTR) for the check characters can be disabled'
as one of the Setup options (described in Operation and Maintenance Manual).
1.4.2.6 IDENTIFICATION BURST (PE, DDPE MODE)
ID/CCG Level
The level identifies
that an ID burst is being detected for PE or DDPE.
1.4.2.7 FILE MARK
FMK
Pulse
P2-16
P2-14
File mark is pulsed when a file mark is detected on the tape during a read operation
or during a
write file mark operation. The FMK line will be pulsed after a complete
file mark has been read. When reading NRZI file marks, read strobes are issued to the
interface.
1-12

93-09600-994
1.4.2.8 WRrm STROBE
WSTR
Pulse
General Description
P2-36
This line pulses each time a data character is written onto tape. W STR samples the
write data lines WP, W O-W 7 from the Host and copies this inform at ion character by
character into the unit's write 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, no data will be written to
tape.
1.4.2.9 READ STROBE
RSTR Pulse
P2-34
This line consists of a pulse for each character of read information allowing the
transmission of data to the host. This signal should be used to sample the read data
lines RP, RO-R 7.
In a NRZI Read operation the transmission of CRC and LRC data characters will be
flagged by the check character gate (CCG) signal as described previously under Check
Character Gate.
1.4.2.10 READ DATA LINES
RP, RO-R7 Levels
These lines transmit the read data for all three densities. Each character read from
tape is made available by parallel sampling the read lines using the Read Strobe. The
data remains on the read lines for a full character period.
1.4.2.11 READY
RDY Level
P2-28
RDY is true (low) only when the transport is ready to receive external commands; the
following conditions must exist:
a. All interlocks
are made.
b. Initial load or rewind sequence is complete.
c. Transport is on-line.
d. Transport is not rewinding.
1.4.2.12 ON LINE
ONL Level
P2-44
When ONL is true (low), the transport is under host or remote control. ONL false
(high) indicates
the transport is under local control.
1.4.2.13 REW IN DIN G
RWG
Level
P2-30
RWG is true (low) when the transport is engaged in a rewind operation or returning to
the load point at the end of the rewind operation.

transport supply hub.
1.4.2.15 LOAD POINT
LDP Level
P2-4
LDP is true (low) when the load point marker is under the BOT sensor and the
transport is not rewinding. After receipt of amotion command the signal will remain
true until the load point marker leaves the BOT sensor area.
1.4.2.16 END OF TAPE
EOT LeVel
P2-22
EOT is true (low) when the EOT marker is detected in the forward direction. EOT
goes false (high) when the EOT marker is detected in reverse (REWIND).
1.4.2.1'1 DENSITY

1.4.3.1 READ FORWARD
On receipt of the Read Forward command loaded into the unit with the GO pulse, the
FBY signal goes true and the unit begins to accelerate the tape up to nominal
velocity. When the tape is up to speed and the data block to be read is detected,
DBY shall go true. Read Strobes (RSTR) accompany the decoded data. DBY will go
false after the complete block has been read indicating readiness of the unit to accept
a new command. If no command is received, the unit will either stop in the gap in 50
ips operation or enter a reposition operation in 100 ips operation and FB Y will go
false.
Rev B 1-15

General Description 93-09600-994
1.4.3.2 READ REVERSE
This command is similar to. a read forward command except that the tape motion is in
the reverse direction.
1.4.3.3 WRlI'H
On receipt of the Write command loaded into the unit with the GO pulse, the FBY
signal goes true and the unit begins to accelerate the tape up to nominal velocity.
When the tape is up to speed and the data block is ready to be written, DB Y shall go
true. Write Strobes (W srR) are transmitted to the Host by the unit and the Host
presents each data byte to be written. When LWD is received by the unit from the
Host, the unit will finish reading the block, error status shall be made available to the
Host and then the unit shall force DBY false indicating the end of the block just
written. FBY will remain true if a new command in the same direction is received
within
the com mand reinstruct period. If no com mand is received, the unit will either
stop in the gap in 50 ips operation or .enter a reposition operation in all 100 ips write
operation and FB Y will go false.
1.4.3.4 READ REVERSE EDIT
The Read Reverse Edit command besides providing data establishes the correct position
of. the tape relative to the magnetic head prior to the Host executing a Write Edit
command.
1.4.3.5 WRrm .EDIT
The Write Edit command must be preceded by a Read Reverse Edit command. The
Write Edit command allows a block
of the same leD&'th to be written over an already
existing data block on the tape.
1.4.3.6 WRITH FILE MARK
This command invokes the writing of a file mark in the density selected.
1.4.3.7 FIXED LEN GTH ERASE
This command invokes a 3.5 inch length of tape to be erased. This command is always
executed in
the forward direction of tape motion.
1.4.3.8 DATA SECURITY ERASE
This com mand invokes tape to be erased from the present tape position to a point 3
feet past End of Tape.
1.4.3.9 fPACH FORWARD AND fPACH REVERSE
These commands are similar to a Read Forward or Read Reverse command, except
that no read strobes are returned to the Host and no error checking is performed.
However,
the unit will check and report if the record is a file mark.
