All output signals from the Model 9610/9660 are driven by open collector type line drivers
capable of sinking up to 36 rnA (2S standard unit loads) in the low true state. Open lines will
result in false signal levels.
1.3.4 INTERFACE CABLES
To meet FCC and Electrostatic Discharge (ESD) specifications, 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
Pl-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.

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 Set-Up Options (described in Section IV), but
terminates automatically if a Write Command is received before the selected limit.

General Description
1.4.1.10 REWIND
REW
Pulse
93-09610-004
Pl-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 immediately, then rewind to load point and unload
the tape.
1.4.1.12 LAST WORD
LWD
Level
PI-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 formatter 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 Section IV) allows the polarity of this level to be selected.
1.4.1.14 WRITE DATA LINES
WP, WO-W7
Level
Pl-22, 10, 12, 30, 26, 6, 32, 28, 24
These 9 lines transmit write data from the controller to the formatter. The 8 data bits
appearing on WO-W7 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 WO-W7.
The first character of a record should be available on these lines within one character period
after DBY goes true and remain until the trailing edge of the first WSTR 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 LWD is
set true by the controller when the last character is transmitted.

If tape is not loaded, the selected unit will execute a load sequence. Upon completion of the
load sequence, the unit will go on-line. If tape is loaded and the selected unit is not on-line, it
will go on-line.
1.4.2 INTERFACE OUTPUTS (9610/9660 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 Set-Up Options (described in Section IV) 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 DENSITIES)
HER Pulse P2-12
When true, this pulse indicates one or more of the following error conditions has occurred. The
following
list summarizes the errors for all four densities.
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 DBY 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 wri te 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.
m. ACRC error.
n. Simultaneous dropouts in two or more tracks during a write operation.
o. Simultaneous dropouts in three or more tracks during a read operation.
1.4.2.4 CORRECTED ERROR (PH, 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.
1-11

General Description
93-09610-004
1.4.2.5 CORRECTED ERROR (GCR)
CER Pulse
P2-42
This pulse indicates the following:
a. A single or dual track dropout has been detected and the drive performs an error
correction in a Read operation.
b. A single
track dropout has been detected and the drive performs an error correction in
a Read
after Write operation.
Note:
Corrected error reporting can be disabled in GCR mode as one of the Set-Up Options.
1.4.2.6 CHECK CHARACTER GATE (NRZI MODE ONLy)
IDIC CG 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
Set-Up Options (described in Section IV).
1.4.2.7 IDENTIFICATION BURST (PH, DDPH, GCR MODE)
ID/CCG Level
The level identifies
that an ID burst is being detected for PE, DDPE, or GCR.
1.4.2.8 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 fUe mark has been
read. When reading NRZI file marks, read strobes are issued to the interface.
1.4.2.9 WRITE STROBE
WSTR Pulse
P2-36
This line pulses each time a data character is written onto tape. WSTR samples the write data
lines WP, WO-W7 from the Host and copies this information 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.
1.4.2.10 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-R7.
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.

1.4.2.16 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 a motion command the signal will remain true until the load point
marker leaves the BOT sensor area.
1.4.2.17 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).

General Description
1.4.2.18 DENSITY
DENO,DENI
93-09610-004
Level
Pl-14, P2-26
Binary-coded signals that indicate the current density of the Drive. Two coding schemes are
available. These schemes are:
DENS OUT DENS OUT
NRZONLY CODED
DENSITY DEN 1 DEN 0 DEN 1 DEN 0
800 1 0 1 1
1600 0 0 0 1
3200 0 0 1 0
6250 0 0 0 0
The coding scheme used can be selected as one of the Set-Up Options (described in Section IV).
1.4.2.19 SPEED
SPD
Level P2-40
SPD true (low) indicates the selected transport is in the high speed streaming mode. A false
level indicates low speed (50 ips).
1.4.3 COMMAND EXECUTION
The following section describes the appropriate combinations of signal lines required to achieve
Command Execution followed by a description of the responses of the Model 9610/9660.
