The drives use industry-standard mounting for 3 -inch full-height
Winchester disk drives.
The drives are designed such that the outer frame should be hard-
mounted to th ehost equipment; no additional/external shock mounts
should be used.
Recommend orientation is vertical on either side, or horizontal with
the Device Electronics board down; other mounting orientations may be
used.
No matter what mounting orientation is used, Micropolis specifies
that the maximum HDA casting temperature not exceed 60*C (140*F).
If the HDA casting temperature measurement cannot be made, the
ambient air temperature around the drive must be kept at or below
50*C (122*F).
Caution:
The mounting screws must be selected so that they do not penetrate
the bottom mounting holes by more than 0.20 inches or the side mount-
ing holes by more than 0.156 inches.
Screws that are too long will short to PCBA components and/or prevent
proper operation of the shock mount system.

SINGLE-ENDED Interface Electrical Characteristics
-------------------------------------------------
Interface control and status signals are digital (open collector TTL)
using industry-standard transmitters and receivers which provide
a terminated, single-ended system.
For active termination, the assigned signals are terminated with 110
ohms to +2.85V (nominal). For passive termination, the assigned
signals are terminated with 220 ohms to +5V (nominal) and 330 ohms to
ground. All signals use open-collector or three-state drivers.
Single-ended drivers and receivers allow a maximum cable length of
six meters (primarily for connection within a cabinet).
Signal transmission requires a single 50-conductor (flat or twisted
pair) cable. A characteristic impedance of 100 ( 10%) ohms is
recommended.
a. Input Characteristics
Each of the drive's signal receivers has the following
characteristics when measured at the interface connector.
1) Low-level input voltage (Signal true) = 0.0 VDC to 0.8 VDC
2) High-level input voltage (Signal false) = 2.0 VDC to 5.25 VDC
3) Low-level input current = -0.4 milliamps at 0.5 VDC
4) High-level input current = 0.1 milliamps at 2.7 VDC
5) Minimum input hysteresis = 0.2 VDC
6) Maximum input capacitance = 25 pF
b. Output Characteristics
Each of the drive's signal drivers has the following
characteristics when measured at the interface connector.
1) Low-level input coltage (Signal assertion) = 0.0 VDC to 0.5
VDC
2) High-level input voltage (Signal negation) = 2.5 VDC to 5.25
VDC
3) Minimum driver output capability = 48 milliamps (sinking) at
0.5 VDC.
c. Terminator Power (TERMPWR at Pin 26)
Terminator Power has the following requirements:
V(TERM) = 4.25 VDC to 5.25 VDC
800 milliamps minimum source drive capability, with 1.0 amp
recommended current limiting (e.g., a fuse).
1.0-milliamp maximum bus loading (except for the purposes of
providing power to an internal terminator).
The drive provides keyed connectors to prevent accidental grounding
or misconnection of terminator power.
DIFFERENTIAL Interface Electrical Characteristics
-------------------------------------------------
Differential interface signals consist of two signal lines which are
denoted +SIGNAL and -SIGNAL.
A signal is defined as true when the +SIGNAL is more positive than
the -SIGNAL.
A signal is defined as false when the -SIGNAL is more positive than
the +SIGNAL.
Differential drivers and receivers allow a maximum cable length of
25 meters.
Signal transmission requires a single 50-conductor cable. A
characteristic impedance of 100 ( 10%) ohms is recommended for un-
shielded flat or twisted pair ribbon cable.
A minimum conductor size of 28 AWG should be employed to minimize
noise effects and ensure proper distribution of optional terminator
power.
A stub length of no more than 0.2 meters is allowed off the main-line
interconnection within any connected equipment.
a. Input Characteristics
Each of the drive's signal receivers has the following
characteristics when measured at the interface connector.
I (input current on either input) = 2.0 milliamps, maximum
Note: These characteristics include both receivers and passive
drivers.
This requirement is met with the input voltage varying between
-7V and +12V, with power either on or off, and with hysteresis
equaling 35 millivolts, minimum.
b. Output Characteristics
Each driven signal has the following characteristics when
measured at the interface connector.
VOL (low-level output voltage) = 1.7V maximum at IOL
where IOL = 55 milliamps
VOH (high-level output voltage) = 2.7V maximum at IOH
where IOH = -55 milliamps
VOD (differential voltage) = 1.0V minimum, with common-mode
voltage ranges from -7 to +12
VOL and VOH are measured between the output terminal and the
SCSI device's logic ground reference.
c. Terminator Power (TERMPWR at Pins 25 and 26)
Terminator Power has the following requirements:
V(TERM) = 4.0 VDC to 5.25 VDC
600 milliamps minimum source drive capability, with 1.0 amp
recommended current limiting (e.g., a fuse).
1.0-milliamp maximum bus loading (except for the purposes of
providing power to an internal terminator).
The drive provides keyed connectors to prevent accidental
grounding or misconnection of terminator power.
Adjustments and Maintenance
---------------------------
The drives requires no adjustments or periodic maintenance;
additionally, no mechanical adjustments are required to prepare a
system for handling or shipment.
Field-Replacable Components
---------------------------
The concept of repair by replacement of complete functional
components is utilized in the drive, resulting in an MTTR of less
than 15 minutes.
Data Transfers
--------------
The drives are capable of transferring data up to 10 MBytes/sec in
synchronous mode and 5 MBytes/sec in asynchronous mode.

MICROPL. 2217/2210/2207/2205-S/D PRODUCT DESCRIPTION 135861 REV. A
The single-ended and differential interface drive is compatible with
the "ANSI CCS" and "SCSI-2" versions of the industry-standard Small
Computer System Interface (SCSI) specification.
Media Defects
-------------
Media defects are physical characteristics of the media which result
in repetitive read errors when a functional drive is operated within
specified operating conditions.
At the time of manufacture, a media test system evaluates every
drive and identifies each media defect location. The defective
areas are identified by head address (HD), cylinder address (CYL),
and number of clocks from Index (CFI).
The list of manufacturer-found defects is stored on the drive in a
reserved, write-protected area accessible by the SCSI controller.
This list is known as the MDL (Manufacturers Defect List) or PList
(Primary Defect List).
A printed listing of the defects is also shipped with each drive. The
entries it contains can be mapped out (reassigned) automatically at
format control parameter bits.

----------------------------------+--------+
Multi-Segment Read Ahead
------------------------
The Multi-Segment Read Ahead function partitions the 256K data buffer
into multiple buffers or segments.
The read-ahead function causes the drive to transfer the requested
block into its buffer and continue to read sequential blocks until
the buffer (or segment) is filled or another command is received.
On subsequent request data, the buffer will be checked for the
requested blocks. If the data already resides in the buffer, it will
be transferred to the host and no media access will be necessary.
This results in a significant improvement in performance.
