Pin position 47 through 50 are used for drive address setting.

Jumpers

Jumper Setting
==============

Drive Address Setting
---------------------
A jumper is available at the interface connector to determine the
drive address.

49-Pin
When grounded, no spin-up at POR.
When open => pull-up, normal spin-up at POR.

Cable Selection
---------------
Using Cable Selection, the drive address depends on the condition of
pin 28 of the AT interface cable. In the case when pin 28 is ground
or low, the drive is a Master. If pin 28 is open or high level, the
drive is a Slave.

Cabling
-------
The maximum cable length from the host system to the HDD plus circuit
pattern in the host system shall not exceed 18 inches.

AT Signal Connector
-------------------
The AT signal connector is designed to mate with Dupont part number
69764-044 or equivalent.

   +-----------------+

The drive will operate in all axis (6 directions).

Performance and error rate will stay within specification limits if
the drive is operated in the other permissible orientations from
which it was formatted. Thus a drive formatted in a horizontal
orientation will be able to run vertically and vice versa.

The drive must be securely mounted in the system to prevent motion or
vibration during a seek operation or spindle rotation using
appropriate screws or equivalent mounting hardware.

The recommended mounting screw torque is 3.0 0.5 kgf.cm.

The recommended mounting screw depth is 3.0 0.3mm for bottom and
3.5 0.5mm for horizontal mounting.

 I/O Connector
 -------------
 PIN 39  = -DASP
 PIN 41  = +5V LOGIC PWR
 PIN 42  = +5V MOTOR PWR
 PIN 43  = GND
 PIN 44  = RESERVED

 There are two input pins for +5 Volt power supply, "+5V LOGIC" and
 "+5V MOTOR". +5V LOGIC is connected to the internal logic circuits
 and +5V MOTOR is connected to the spindle motor and motor driver.

 It is possible to turn on and off +5V LOGIC by an external switch
 circuit to reduce power consumption to the least possible. In this
 mode, a voltage drop out due to the motor spin up current can be
 reduced by connecting +5V MOTOR line into the system power source
 directly.

If the above power management option is used, all signal lines that
will be electrically active in the host system while the HDD is
disconnected from power line shall be isolated by Three-State line
drivers. Internal leakage through ESD protection circuit may pull
down LPUL (Least Positive Up Level) of Logic signal.

Use both lines in parallel, for regular HDD applications.

Air Cooling Requirement
-----------------------
The host system must provide sufficient air flow across the drive to
maintain the temperature at less than 60*C (measured at the centre of
the files top cover).
