P4 Wait Spin
-------------
7-8 CLOSED Wait spin
When a jumper is connected across pins 7 and 8, the drive will not
power-up until receipt of the START/STOP command with the Start bit
set accordingly. For remote operation of this feature it is only
necessary to connect pin 7 to ground.
The state of this pin is only monitored on removal of the internal
reset to the drive after power has been applied to the drive.
P4 Parity
----------
9-10 CLOSED Enable parity
When a jumper is connected across pins 9 and 10, the drive will
enable parity checking. The use of this jumper excludes the enabling/
disabling of parity by the use of the MODE SELECT command. For remote
operation of this feature it is only necessary to connect pin 9 to
ground.

Notes on Installation
=====================
Drive Mounting and Installation
-------------------------------
When installing the drive into an enclosure, the breather holes on
the drive top cover must not be obstructed. At least 0.1 inch
clearance must be provided between the top cover and the host frame.
There must be at least 0.1 inch clearance between the drive housing
and the host frame to ensure functional vibration isolation.
The drive may be mounted in any orientation and is supplied complete
with threaded mounting bracket. The drive is mounted using 6/32 UNC
screws with maximum engagement of 0.25 inch.
The drive installation must provide adequate air flow to ensure that
the maximum casting temperature of the head/disk assembly does not
exceed 60*C.
Physical Description
--------------------
SCSI devices are daisy-chained together using a common cable. Both
ends of the cable are terminated. All signals are common between
SCSI devices.
The RO 3000T uses single-ended drivers and receivers, which allow a
maximum cable length of six metres.
Cable Requirements
------------------
A 50-conductor flat cable or 25-signal twisted-pair cable shall be
used. The maximum cable length shall be 6.0 metres (19.8 ft).
A stub length of no more than 0.1 metres (3.94 in) is allowed off the
mainline interconnect within any connected equipment.
A minimum conductor size of 28 AWG shall be employed to minimize
noise effects and ensure proper distribution of optional terminator
power.
Connector Requirements
----------------------
The drive connector is a 50-conductor connector consisting of two
rows of 25 male pins with adjacent pins 2.54 mm (0.1 in) apart.
The cable connector shall be a 50-conductor connector consisting of
two rows of 25 female contacts with adjacent contacts 2.54 mm
(0.1 in) apart. The 3M P/N 3425-300 cable connector is recommended.
The power connector is a 4 pin AMP Mate-N-Lock P/N 350211-1 (or
equivalent) mounted on the reserve side of the PCB. The recommended
mating connector is AMP P/N 1-480424-0 (or equivalent) socket housing
using AMP pin P/N 350078-4 (or equivalent).
Electrical Description
----------------------
All assigned signal are terminated with 220 ohms to +5V (nominal) and
330 ohms to ground at each end of the cable. All signals use open-
collector drivers. The terminators are removable.
Output Characteristics
----------------------
Each signal driven by the RO 3000T has the following output
characteristics when measured at the drive's connector:
Signal assertion = 0.0 volts dc to 0.4 volts dc.
Minimum driver output capacity = 48 milliamps (sinking) at 0.5
volts dc.
Signal negation = 2.5 volts dc to 5.25 volts dc.
Input Characteristics
---------------------
Each signal received by the RO 3000T shall have the following input
characteristics when measured at the drive's connector:
Signal true = 0.0 volts dc to 0.8 volts dc.
Maximum toatl input load = -0.4 milliamp at 0.4 volts dc.
Signal false = 2.0 volts dc to 5.25 volts dc.
Minimum input hysteresis = 0.2 volts dc.
Terminator Power (Optional)
---------------------------
The RO 3000T is configured to supply terminator power,(TERMPWR), with
the following characteristics:
VTERM = 4.0 volts dc to 5.25 volts dc.
800 milliamps minimum source drive capability.
1.0 milliamp maximum sink capability.
SCSI Bus
--------
Communication on the SCSI bus is allowed between only two SCSI
devices at any given time. There is a maximum of eight SCSI devices.

===================
The following features are supported:
- Up to 48K Bytes dual ported FIFO data buffer, configured as a
intelligent cache
- Will support a logical sector size of 512 or 1024 bytes
- Disconnected operations with arbitration for reselection
- Command linking
- Supports automatic read and write reallocation
- 32 bit ECC error detection and correction
- Average data transfer rate of 1.25 MBytes/second
- 1 : 1 interleave factor
- Operation with arbitrating and non-arbitrating hosts
- Extended SCSI command set
- Diagnostics and error reporting
- Hardware parity link option
- Wait spin-up link option
- Low power standby mode when data access not occurring
Defect Handling
---------------
Disc defects are handled by the RO 3000T using a sector sparing
technique. During manufacture the drive is formatted using a format
control code of 1EH. After this format, the drive allows the
initiator access to all physical sectors. The drive is tested in this
mode and any defective sectors are entered into a list known as the
Primary Defect List or P-List. The P-List is stored in sectors 0 and
10 of the special Maintenance Track. This track is physically
Cylinder -2, Head 0 and is NOT part of the logical address space
normally available to the user. The P-List can only be altered or
erased by reformatting the maintenance track (Command E1H) or re-
formatting the entire drive (Command 04H) using format control codes
1EH or 16H.
LED Error Codes
---------------
Under certain fault conditions, the following error codes will appear
on the SELECT LED on the front panel.
HEX CODE Definition
01 The drive has detected that the spindle motor speed is out
of tolerance ( 10%).
06 After stepping the maximum number of cylinders, the drive
could not achieve correct track zero status.
07 The spindle motor did not start at power up.
08 Spindle motor failed initial 1% speed check at power up.
0A No track crossing signal during a seek.
0B No servo data.
0C +12V supply failure.
0D Hardware Interrupt Error.
All the above error codes are designatd FATAL, and resetting of the
drive can only be accomplished by powering off, then on again.
If the drive has a FATAL error, it will switch off power to both the
voice coil and spindle motors and flash the fatal error code on the
SELECT LED on the front panel. The drive will still respond to
commands sent across the SCSI interface, but will not execute any of
them except TEST DRIVE READY, INQUIRY or REQUEST SENSE.
