when the ID is changed the user could fail to configure both J5 and
J7 the same. The drive ID is binary coded positionwise (A2, A1, A0)
(least significant position on the right), i.e. jumper in position
A0 is drive ID 1 etc.
J7 Sync Spindle
----------------
4 Used as a cable connection for the reference index signal
(REFSIG+) for sync spindle feature. J7 pin 7 is REFSIG+, pin 8
is GND. When no cable is connected, a jumper must be installed.
OEM standard drives are shipped with jumper installed.
The Synchronized Spindle Interface (SSI) allows several drives
operationg from the same host to operate their spindles at a
synchronized rotational rate.
J7 Remote LED
--------------
5 Used if needed for a connection to a remote located LED indicator
Pin 10 top (away from PWA), the anode connection, connects in the
drive to the +5V supply through a pull-up resistor. Pin 9
(bottom), the cathode connection connects in the drive to signal
common through the emitter-collector jumction of a transistor
switch that controls the LED on/off condition.

Notes on installation
=====================
Drive Orientation
-----------------
The balanced rotary arm actuator design of the drive allows it to
be mounted in any orientation. All drive performance characterization
however, has been done with the drive in horizontal (disc level) and
vertical (drive on its side) orientations, and these are the two
preferred mounting orientations.
The drive is designed, manufactured, and tested with a "Plug-in and
Play" installation philosophy. This philosophy minimizes the
requirements for highly trained personnel to integrate the drive
into an OEM's system, whetherin a factory or field environment.
- Insure that the SCSI ID is not the same as the host adapter. Most host adapters use SCSI ID 7.
- If multiple devices are on the bus insure that the SCSI ID of the drive is not already used by other devices on the bus.
- If the drive is the only device on the bus it should be attached to end of the SCSI bus cable, and terminators should be installed (provided external terminators are not used).
- If the drive is attached to a bus already containing other devices, and the drive is not attached to the end of the bus, the terminators should be removed.
- Set all appropriate option jumpers for desired operation prior to power on. If jumpers are changed after power has been applied the drive must be power cycled for the new settings to be affect.
- In all cases additional drives or software will be necessary to logically install the drive onto the system.
Mounting Holes
--------------
Four 6-32 UNC-2A screws are required for installation. Maximum
mounting screw length into chassis is 0.125 inches (3.17 mm) and
0.20 (5.1 mm) into bottom holes.
Cooling
-------
Cabinet cooling must be designed by the customer so that the
ambient temperature immediately surrounding the drive will not exceed
temperature conditions. Specific consideration should be given to
make sure adequate air circulation is present around the components
on the PWA.
Service Tools
-------------
No special tools are required for site installation or recommended
for site maintenance. The depot repair philosophy of the drive
precludes the necessity for special tools. Field repair of the drive
is not practical since there are no user purchasable parts in the
drive.
Air Cleanliness
---------------
The drive is designed to operate in a typical office environment with
minimal environment control.
Physical Description
--------------------
Model ST1481N/ND and ST1581N/ND disc drives may be chained together
or with other compatible SCSI devices using a common cable. The Model
ST1481N and ST1581N implement an interface having single ended
drivers and receivers. The Model ST1481ND and DT1581ND implement an
interface having differential drivers and receivers. Devices having
single ended interface circuits cannot be on the same daisy chain
with devices having differential interface circuits. A maximum of
8 SCSI devices (including the Host) may be daisy chained together.
The SCSI Devices at both ends of the daisy chain are to be
terminated. Intermediate SCSI devices shall not be terminated. Remove
the terminator resistor packs, not the terminator power source
selector jumper.
Single Ended I/O Circuits
-------------------------
The maximum total cable length for use with drives having single
endeded I/O driver and receiver circuits shall be 6 metres (19.7 ft.)
when operating at line data transfer rates greater than 5 Mbytes/sec
(Fast SCSI). A stub length of no more than 0.1 metre (0.33 ft.) is
allowed off the mainline interconnection with any connected
equipment. An ideal impedance match with cable terminators implies a
cable characteristic impedance of 132 ohms.
Differential I/O Circuits
-------------------------
The maximum total cable length for use with drives having
differential I/O drivers and receiver circuits shall be 25 metres
(82 ft.). A stub length of no more than 0.2 metre (0.66 ft.) is
allowed off the mainline interconnection with any connected
equipment. An ideal impedance match with cable terminators implies
a cable characteristic impedance of 122 ohms.
General Cable Characteristics ----------------------------- In general, the cables having the characteristics impedances given in Differential I/O Circuits and Single Ended I/O circuits are not available; however, impedances that are somewhat lower are satis- factory. A characteristic impedance of 100 ohm + 10% is recommended for unshielded flat or twisted pair ribbon cable. However, most available cables have somewhat lower characteristic impedance. To minimize discontiuties and signal reflections, cables of different impedances should not be used in the same bus. Implementations may require tradeoffs in shielding effectivness, cable lenght, the number of loads, transfer rates, and cost to achieve satisfactory system operation. If shielded and unshielded cables are mixed within the same SCSI bus, the effect of impedance mismatch must be carefully considered. Proper impedance matching is especially important in order to maintain adequate margin at Fast SCSI transfer rates.
Only nonshielded cable connectors are applicable. A 50 conductor flat
cable or 25 twisted pair cable shall be used. A minimum conductor
size of 28 AWG should be used to minimize noise effects.
Suggested nonshielded flat cable part numbers are:
Flat cable - 35M-3365-50 Twisted pair - Spectra Twist in flat 455-248-50
Equivalent parts may be used.

DC Cable and Connector
----------------------
The disc drive receives DC power through a 4 pin rigth angle
connector mounted on the rear of the Main PWA. Recommended part
numbers for the mating connector are included below, but equivalent
parts may be used.
Type of cable: 18 AWG
Connector: AMP 1-480424-0
Contacts: AMP 60619-4 (Loose Piece); AMP 61117-4 (Strip)
Connector Requirements
----------------------
The nonshielded cable connector shall be a 50 conductor connector
consisting of two rows of 25 female contacts with adjacent contents
100 mils apart.
Recommended Mating Flat Cable Connector Part Numbers are:
Closed end 3M-3425-7000 W/O Strain Relief, No Center Key
(for cable 3M-3425-7050 With Strain Relief, No Center Key
ends) Dupont-66900-290 With Strain Relief, With Center Key
Open end 3M-3425-6000 W/O Strain Relief, No Center Key
(In Daisy- 3M-3425-6050 With Strain Relief, No Center Key
chain) Dupont-66900-250 With Strain Relief, With Center Key
Grounding
---------
Signal ground (PWA) and HDA ground are connected together in the
drives and cannot be separated by the user. The chassis ground is not
connected to the HDA and PWA ground. A chassis grounding quick
disconnect Tab is provided at the rear of the drive above the DC
power connector. Mating connector to connect a system chassis ground
to the grounding tab is AMPP/N 62137-2. If it is desired for the
system chassis ground to be connected to the HDA/PWA ground, the
systems integrator or user must provide a flexible ground strap be-
tween HDA and chassis ground point. Such a strap must not interfere
with the ability of the HDA to meet shock and vibration
specifications.
Termination ----------- The reference signal (REFSIG+) is terminated with a 2K ohm resistor. Each drive has a termination resistor located on the Main PWA. The terminator resistor is not removable and is always in the circuit.
For the Single-ended I/O ST1481N and 1581N applications the SCSI bus
MUST be terminated at both ends with ANSI SCSI-2 Standard's Alter-
native 2 termination (active termination), especially if the bus will
be operated at FAST SCSI transfer rates. The ST1481N and ST1581N
provide active termination as the on-board termination option.
Note: All terminators used in the daisychain absolutely must be
active terminators as described above.
Differential I/O models ST1481ND and ST1581ND do not have provisions
to add terminator sockets on the PWA. The user or systems integrator
must provide a terminator arrangement external to the drive.
Drivers and Receivers
---------------------
The driver circuits have the following electrical specifications:
Negated (False): 0.0 V to +0.4 V @ I = - 48 mA (max). Asserted (True): +2.24 V to +5.25 V @ I = +250 uA
Synchronized Spindle operation ------------------------------ The interface consists of a twisted pair cable that connects the drives in the synchronized system in a daisy chain configuration. Master/slave operation will be automatically set by the drives in the system at power up time, or each drive in the system can be configured by the host (using Mode Select command) to operate in either the master or slave mode. While loading heads after power up, a drive checks for occurrences of the reference signal (REFSIG+). If there are no reference pulses occuring, the drive takes over as a master and begins sending the reference index signal. Drives can be re-configured by the host any time after power up to be master or slave by use of the Mode Select command Rigid Disc Drive Geometry page. The master provides the reference signal to which all other drives phase lock, including the master. There is only one master per system, and that can be a drive or the host computer. All drives may be configured as slaves allowing the host to provide the reference signal. All drives default to the synchronized mode when powered up.
Each drive can later be configured for the non-synchronized mode in
which it ignores any reference signal that might be present. The
connection of the synchronized reference signal to the host is
required only if the host is to provide the reference signal. If the
host does not provide the reference signal, the host should not be
connected and the master should be drive #1.
Features
SEAGATE ST1481/1581-N/ND PRODUCT MANUAL 77738471-A
Standards
---------
The ST1481N/ND, ST1581N/ND has been developed as a system peripherals
to the highest standards of design and construction. The drives
depends upon its host equipment to provide adequate power and
environment in order to achieve optimum performance and compliance
with applicable industry and governmental regualations. Special
attention must be given in the areas of safety, power distribution,
shielding, audible noise control, and temperature regulation.
The ST1481N/ND, ST1581N/ND is a UL Recognized component per UL1950
and a CSA Certified Component per CSA C22.2, No. 950-M89. It also
meets the requirements of DIN VDE 0805/05.90 and EN 60950:1988 (IEC
950).
The ST1481N/ND, ST1581N/ND, as delivered, is designed for system
integration before use. It is supplied as a component or
subassembly. as defined to the FCC Rules and Regulations, Part 15,
Subpart J governing EMI of computing devices end the Radio
Interference Regulations of the Canadian Department of
Communications. The drives are, therefore not directly subject to
the FCC rules and regulations or the Radio Interference Regulations
of the Canadian Department of Communications.
Media Description
-----------------
The media used on the drive has a diameter of approximately 3.5
inches (89mm). The aluminium substrate is coated with a thin film
magnetic material, overcoated with a proprietary protective layer
for improved durability and environmental protection.
Defect and Error Management
---------------------------
The drive, as delivered, complies with this specification. The read
error rate and specified storage capacity are not dependent upon use
of defect management routines by the host (initiator).
Defect and error management in the SCSI systm involves the drive
internal defect/error management and SCSI systems error
considerations (errors in communications between Initiator and the
drive).
Power Sequencing
----------------
Power sequencing is not required for the drive. The drive protects
against inadvertent writing during power up and down. Daisychain
operation requires that power be maintained on the terminated unit
to ensure proper termination of the peripherals I/O cables.
Temperature
-----------
The drive will meet all specification over 41*F to 122*F (5*C to
50*C) operating ambient temperature range with a maximum gradient of
36* F (20* C) per hour.
Heat/Power Dissipation
----------------------
For drives with single ended interface circuits, typical dissipation
is 12 watts (41 BTUs per hour) of DC power average at nominal
voltages. Typical power dissipation under idle conditions is 9.5
watts (32.4 BTUs per hour).
For drives having differential interface circuits, typical power
dissipation is 13.7 watts (46.8 BTUs per hour) of DC power average
at nominal voltages. Typical power dissipation under idle conditions
is 11.2 watts (38.2 BTUs per hour).
