1Introduction
1.1 Scope
This manual describes the installation and operational features of the USB and SATA
interface Targa Series 4 Removable SATA disk Data Transfer Systems (DTS). Targa’s
Data Transfer Systems has three major components.
Data Transfer Unit (DTU)
Data Transfer Device (DTD)
Ground Support Unit (GSU)
1.1.1 Data Transfer Unit
The Series 4 DTU is a rugged, field deployed unit providing either SATA or USB
interconnections to the Host system as well as the electrical and mechanical support
infrastructures for the removable Data Transfer Device.
The DTU, conforming to the ARINC CDU style (also called Dzus panel mount) is
equipped with an RTCA-DO-160C, Cat Z compliant 28VDC power supply and two rear
panel mount, MIL-C-38999 connectors.
The DTU front panel accommodates four (4) DZUS ¼ turn fasteners and the DTD access
door. The door is opened by simply rotating the ¼ turn door latch counter-clockwise.
This action releases the door lock mechanism and as the door is opened, an optical sensor
is tripped and the DTU executes an orderly power shutdown of the DTD SATA interface
to the DTD. Once the door is open, the DTD can be inserted through the front panel slot
and gently pushed into place. The door is locked by simply rotating the latch clockwise.
1.1.2 Data Transfer Device
The Series 4 DTD is a rugged, removable media containing a 2.5" Flash SATA disk with
capacities up to 256 GBytes. Targa is continually evaluating and offering SATA FLASH
disks from the various SSD manufacturers as well as new designs from established
suppliers. The SATA disk type and or vendor is represented by the disk ID in the DTD
part number. (see below)
Note: Targa’s SATA DTD’s are configured for “fixed frequency” mode of operation
1.1.3 Ground Station Unit
The Series 4 GSU is a desktop, office grade unit providing USB or eSATA
interconnections to ground based data preparation/retrieval computer systems as well as
electrical and mechanical support for the removable Data Transfer Device.

2.6.5 DTU - Auxiliary Input/Output Signals
2.6.5.1 Input: Secure Erase –
Secure Erase is an “active low” input signal that within the Targa DTU is gated through a
Maxim MAX6817 switch de-bounce device before being sensed by the SATA disk in the
DTD. Upon detection, the SATA disk has been configured to execute a high speed
“Clear” and FLASH re-initialization sequence. Duration is approximately 60 seconds,
after which the SATA disk must be re-formatted for the target “file structures”
Note: Erase is activated upon the transition from logic high to logic low
Erase will not trigger if: Erase logic is low at power-on
Erase logic is low when door closed

3Installation & Operation
3.1 Inspection
All Targa products are carefully inspected and tested before shipping. Inspect the
packaging for any evidence of physical damage which may have occurred in transit.
Examine the DTU, DTD, GSU all accessories and documentation. If any item is missing or
damaged, contact Targa Systems.
3.2 Mounting
The Data Transfer Unit conforms to an ARINC CDU style with four DZUS 1/4 turn
fasteners and can be mounted in any orientation.
The Data Transfer Device is keyed for proper insertion into the DTU / GSU and held
securely in place by a wedge lock mechanism when the door is closed.
The Ground Station Unit is intended for desktop use with no mounting provisions.
3.3 Connector Requirements
The Data Transfer Unit is equipped with two MIL-C-38999, Series 2, Rear mount
connector refer to section 2.7 for details.
The Ground Station Unit is equipped with the designated associated interface connector
and a standard AC power connector (See section 2.7).
3.4 DTD Preparation
The DTD as shipped from Targa is formatted with the EXT3 file system directory as used
in our production test environment. In most cases, the DTD will need to be “re-
formatted” to be compatible with the “end use” system’s operating system file structures.
CAUTION - Formatting a DTD will erase existing data
3.5 Handling
The DTD is installed into the DTU via a locking access door. The DTU access door
activates the DTD clamping mechanism, the DTD power control circuit and the interface
bus control circuits.
Prior to installing the DTD into either of the DTU or GSU receptacles, check that the DTD
connector is free of any foreign matter. Failure to do this may result in damage to the
DTU or GSU internal mating connectors.
To install the DTD, open the access door and slide the cartridge into the slot until it is fully
engaged into the mating connector. To remove the DTD, open the access door and grip
the raised edges and gently pull on the cartridge.
Note: For installations where limited access makes it difficult to grasp the DTD, Targa
can provide a “self ejecting “ DTD as a “special” order item. Contact Targa for
details

3.6 DTD Startup
At startup, the DTD SATA Flash disk must mount/initialize the FLASH memory array
before media requests can be processed. The worst case delay can be 5 seconds for large
capacity drives, but the typical delay is approx 3 seconds.
Note: For the SATA DTU, the DTD must be installed during the host boot process to
ensure that the operating system recognizes the removable drive and assigns a
drive letter.
3.7 Data Reliability
The DTD provides enhanced data reliability via the following mechanisms;
· All erase/write operations are performed in a closed loop operation to verify data has
been erased and programmed correctly with the proper voltage margins.
· Data is checked with a powerful Error Correction Code (ECC) that offers a high
degree of data protection.
· Built in defect management with automatically sector reassignment based on
detected memory errors.
3.8 DTU Startup/Shutdown
The DTU door mechanism is designed with an optical sensor, upon detection of a door
opening, the DTU will remove power from the DTD before it can be removed.
- WARNING -
This controlled power down sequence cannot prevent data loss or file structure
discontinuities if the DTD is removed while writes to the DTD are in progress, or if data is
still held in the Host system cache memory. An operator initiated ‘eject’ or ‘file close’
operation should always be done prior to removing the DTD to ensure that all the host
system cached data and file structures have been written to the DTD before it is removed.
Many operating systems provide a “Safe to Remove” prompt when all of the relevant data
has been written to the removable disk .
3.9 Hardware Erase
This is an embedded function within the FLASH disks used in the DTD. The disks have
been configured to perform a “Hhigh Speed Clear” followed by an “initialization” to
prepare the FLASH array for subsequent use. In the event of a power failure during this
process, the SATA disk will automatically resume this process, before it can be accessed .
Upon completion all FLASH memory contents will have been erased and the DTD will
have to have the associated Host file system structures re-written to it before it can be
used.
