DESCRIPTION
1. General
The Hand Held Download Unit (HHDLU), PN 964-0446-001; manufactured by Honeywell, Red-mond, Washington; is used to quickly copy the contents of the Crash Survivable Memory Unit(CSMU) from the SSFDR, SSUFDR, or AR-Series SSFDR while the recorder is installed on theaircraft.The Hand Held Download Unit (HHDLU), PN 964-0446-021; manufactured by Honeywell, Red-mond, Washington; is used to quickly copy the contents of the Crash Survivable Memory Unit(CSMU) from the AR Series COMBI or AT-Series COMBI while the recorder is installed on theaircraft.Once the data has been copied to the HHDLU, it's removable media can be transported to theGround Support Equipment (GSE), Automated Test/Transcription Unit, PN 964-0434-00X,where the data can be transferred and analyzed.The HHDLU may also be used as a Digital Signal Display Unit (DSDU) to monitor the input datastream information (ARINC 573, 717) to the SSFDR, SSUFDR, AR SSFDR, AR-COMBI or AT-COMBI via an RS422 interface.The HHDLU will operate in one of three modes:• Download - receives data from the recorders CSMU.
• DSDU - monitor the ARINC 573/717 data stream of the recorders.
• Self Test
2. Leading Particulars
The HHDLU is designed to operate in the environment of the aircraft flight line and is capable ofoperating in any position. Some care, however, should be taken when inserting and removingthe transportable media.• Length = 8.45 inches
The HHDLU is constructed to facilitate shop repair by having all components/assembliesmounted onto a single backplane CCA which is easily removed with the top cover. Wheneverpossible, plug in assemblies have been utilized. All HHDLU modules or subassemblies areinterchangeable with other assemblies bearing the same part number. No routine maintenanceis required (see IPL Fig. 1). For software maintenance, the HHDLU system program is able tobe updated through the PCMCIA hard disk assembly (item 35, IPL Fig. 1).

Recorders/HHDLU SystemFigure 1
4. HHDLU Operation
The HHDLU is part of the Honeywell Recorder system. The system is comprised of the on air-craft recorder, the HHDLU for data extraction to a transportable media and finally the PC Auto-mated Test/Transcription Unit. The system is shown in Figure 1. The part numbers involved inthe system description are listed below:• On Aircraft Recorder, SSFDR, PN 980-4700-XXX
• On Aircraft Recorder, SSUFDR, PN 980-4120XXXX
• On Aircraft Recorder, AR SSFDR, PN 980-4710-XXX
• HHDLU, PN 964-0446-001
• HHDLU, PN 964-0446-021
• Hard Disk Drive, PN 700-1679-00X
• Automated Test/Transcription Unit, PN 964-0434-00X
The HHDLU operates in one of three modes - Download Mode, DSDU Mode and Self TestMode. Upon power application, the HHDLU conducts an internal self test, checks for removablemedia (hard disk drive) installed in the PCMCIA slot and if so checks for a valid application pro-gram on the removable media.A. Download Mode
Upon the selection of DNLD, the HHDLU will display a series of option messages to the operator for naming the file to be downloaded, performing simple (delete only) file mainte-nance, downloading all or a portion of the data in the Recorder. When requesting a partial
Page 3Jan 05/01 1-1
HoneywellCOMPONENT MAINTENANCE MANUAL
PART NO. 964-0446
download, the operator selects the number of hours back from the time the recorder ceased recording operations (i.e., this corresponds to the most recently recorded flight information). During all data transfers, the display indicates progress with an estimate of time to comple-tion.Depending on the capacity of the removable media, the HHDLU provides enough storage capacity to allow multiple flight data files to be downloaded. In the event that the removable media is full (insufficient storage), the user is warned and prompted to delete any data file on the media to allow the transfer to take place. The HHDLU displays all files therefore permit-ting the user to delete any specific file. The storage space is always checked prior to initiat-ing any download.Errors that occur during the download are indicated to the user through error messages.
B. DSDU Mode
The HHDLU performs the Data Signal Display Unit (DSDU) function by displaying the ARINC 573 data stream contents currently being recorded into the crash survivable memory of the Recorder. The data is displayed on the HHDLU and is monitored via the RS422 inter-face. The HHDLU is capable of displaying the data information of 3 parameters from any subframe and word at any one time. The displayed parameter value (binary, decimal, hexa-decimal or octal; user selectable) is not to be converted into engineering units, but is an accurate duplication of the ARINC data word.
C. Self Test Mode
HHDLU Self Test is broken into two levels. At power on, the HHDLU performs a series of tests including a BIOS test and an internal RS422 wrap around test. This insures basic func-tionality without requiring any external hardware. A more extensive self test is available using a separate wrap around/power cable and software located on the PCMCIA hard drive media. This test includes external RS422 wrap around, PCMCIA media read/write/erase tests, keypad and display tests and is included in the Testing section.
D. Upload Mode
The HHDLU design has provided for the future capability of uploading files from the trans-portable media to an Honeywell LRU such as a Data Management Unit (DMU) or Ground Proximity Warning Computer (GPWC), via the RS422 interface. As in the download mode, the display indicates data transfer progress with an estimate of time to completion.
5. Electrical Interface
The HHDLU has two data interfaces and one power interface. The function of the data inter-faces is to provide a communication channel between the airborne equipment and the HHDLUand to provide the data to the user via the HHDLU's removable media (hard disk assembly).The power required to operate the HHDLU is derived from the airborne unit while on the aircraftor from a 115 VAC 400 Hz or 28 VDC power supply while in a test facility. These interfaces aredescribed in the following paragraphs.A. RS422 Serial Data Link
Communication with the various LRU's is accomplished via an Honeywell high speed data link. This data link is based upon the EIA422 specification and is currently in use on the Recorders. This interface is capable of a 750K baud rate and supports CTS/RTS terminal communication protocol.Transient voltage and shorts to ground protection is provided on all signal input/output lines.
B. Personal Computer Memory Card Interface (PCMCIA)
To facilitate data transportability from the HHDLU, a PCMCIA interface (hard disk assembly, PN 700-1679-00X) is provided. The HHDLU has a single slot which conforms to the PCM-
Page 4 Jan 05/01 1-1
HoneywellCOMPONENT MAINTENANCE MANUAL
PART NO. 964-0446
CIA standard. This standard provides for a removable PCMCIA media device which is an ATA mass storage protocol peripheral, i.e. hard disk assembly which emulates a hard disk drive. The HHDLU also has an internally mounted flash memory as the dedicated system program memory.
C. Power Supply
During the download process the power necessary to operated the HHDLU is derived from the LRU. The HHDLU interface cable provides the necessary data and power signals to the LRU. The HHDLU is capable of operating with input power of 115 VAC, 400 Hz or 28 VDC.
D. Software Updates
The HHDLU program software resident in the flash memory is reconfigurable via the PCM-CIA interface. On power up, the HHDLU displays the software part number and version number until a function mode is selected.
6. User Interface
The user interface has been designed to be as simple as possible. Operation of any of therequired functions is accomplished with a minimum of keystrokes. Selection of the desiredmode is made through a menu system on the display. User input to the HHDLU is made via thefour software programmable function keys. Each menu screen provides a means for canceling aparticular selection so that an operator can always have the capability to return to the mainmenu. Screen examples are shown in the Testing section.A. Menus
The main menu offers a choice of one of the three implemented modes of HHDLU operation. These are described in Para. 4 above.
B. Display
The HHDLU utilizes a 4 line, 20 characters, backlit liquid crystal display.C. Keypad
The keypad consists of four tactile feedback membrane keys. Each key is software pro-grammable with regard to its function.
D. Data Storage
HHDLU operations software is stored on the internal Flash/ROM drive. Sufficient storage space is provided to permit future HHDLU applications growth. The HHDLU operations soft-ware is programmable through the removable media port (PCMCIA).The HHDLU download file storage capability is dependent upon the data storage capacity of the removable PCMCIA compatible media (hard disk assembly). The minimum capacity for a 1X (64 word per second) recorder download is 10 megabytes, therefore the capacity of the memory card or hard disk assembly must be 10 megabytes or more. Similarly, for a 2X recorder download, 20 megabytes is needed. Honeywell will provide, as a minimum, a 42 megabyte hard disk assembly with each HHDLU.Data files are stored on the removable media with the default file name format.• DOWNLDXX.DLU
Where XX in the default is 00 and is incremented upward with each new file to download. This permits the user to determine the oldest file for deletion should insufficient memory (data storage) space exist. The HHDLU also allows the user to rename any default file pre-sented.

OPERATING INSTRUCTIONS
This section describes the operating procedures for the HHDLU.The HHDLU is connected to the appropriate Recorder as shown in Figure 1, Description and Oper-ation section.NOTE: Since the HHDLU derives its power from the recorder, the recorder power must be on for the HHDLU to operate.
Press the HHDLU red power switch to apply power to the HHDLU.1. Initialization
The HHDLU initializes when power is first applied. During this initialization the unit performs amemory test.NOTE: The HHDLU will take approximately 30 seconds to initialize. During this period, the display will be inactive.
When the removable hard disk assembly (hereafter called removable media) is inserted, therewill be an additional delay while the removable media performs its own initialization. When theinitialization is completed, the HHDLU Main Menu will be displayed.NOTE: A complete test of the HHDLU hardware may be accomplished by performing the testing in the Testing sec-
tion. This test requires the use of a wrap around test cable, PN 704-2555-001, and removable media, PN 700-1679-00X (supplied with HHDLU), with the ATP software installed.
2. Main Menu
The Main Menu options depend on the status of the removable media at the time of initialization.Three possibilities exist: • No removable media present - - this would be suitable for DSDU use only.
• Removable media present - - this is the most common configuration, suitable for down-load and/or DSDU use.
• Removable media, with application software, present - - application software has been placed on the removable media. The software, depending on its configuration, may be loaded into the HHDLU and operated or accessed directly from the removable media. This would be used, for example, to update the HHDLU embedded software or run a diag-nostic program from the removable media.

3. Downloading Recorder Data
The HHDLU provides the following download functions:• Full recorder data extraction - - depending on the data rate of the recorder, the removable
media will hold two (2X data rate) or four (1X data rate) full recorder downloads.
• Partial recorder data extraction - - the user may select anywhere from 0.1 to 27.2 hours of data to be downloaded. The HHDLU will then save only the specified amount of the most recent data from the recorder.
• Automatic/Manual data file naming - - the HHDLU provides automatic data file naming, but also allows the user to override this option and enter alternate file names.
• Memory maintenance - - the HHDLU monitors the removable media capacity and, prior to data extraction, prompts the user if there isn't enough room to store the specified amount of flight data. The user is given the option to delete data files from the removable media or insert another removable media.
A download will take anywhere from 6 to 12 minutes, depending on the recorder configuration(1X or 2X).A. The Download Menu

TROUBLESHOOTING
1. General
This section contains troubleshooting procedures for the Test System. This section also containsschematics and wiring diagrams. The information is intended as a guide in troubleshooting faultsthat occur during testing. It is not a complete analysis of all possible faults.
2. Diagnostics Techniques
Troubleshooting component failures within a circuit or network should be done as follow:A. Check the key signal or pulse faults between related circuits or networks.
B. Isolate fault to a single circuit or network if any key signals or pulses are absent or abnormal.
C. Isolate fault to one area or group of components within a circuit by checking for absent or abnormal signals or pulses between major devices.
D. Check suspected devices for internal or external fault conditions and lines for failures affect-ing circuit operation. This isolates the fault to a component or other circuit elements.
E. Typical Failure Modes
Most failures will fall into 1 of 3 groups: timing or sequence failures, transient or anomalous failures, and internal and external device failures.As a rule, timing or sequence failures do not occur often. Timing parameters of digital inte-grated circuits are rarely out of tolerance or marginal. The exception to this rule is power supply variations. When supply voltages are too high, speed of device operations increases. Likewise, speed decreases when supply voltages are too low. So, if operations timing is marginal or critical, hardware failures can result. A drastic change in supply voltage, espe-cially a low voltage, can affect anything from 1 device to system operations.Transient or anomalous faults are equally rare, but much more difficult to troubleshoot. Usu-ally, transient faults are related to timing or random faults that depend on the operation being performed. If that operation is not executed, then the fault does not occur, or the factors combining to cause the failure may occur only once.Anomalous or one-of-a-kind faults also result from a combination of factors that never occurred before. Such faults frequently correct themselves before they can be isolated, and those that are isolated and corrected, generally do not recur. The most numerous failures, internal device failures, and those occurring externally in the circuit are:(1) Open Bond -- either the inputs or outputs driven by a particular device are left to float,
usually at approximately 1.4 to 1.5VDC.
(2) Short -- either between an input and output, or supply voltage (Vcc) to ground, affect all connecting signal lines. Input-to-output shorts cause a low or ground, while supply shorts cause high or Vcc level.
(3) Short -- between 2 pins, neither of which is a supply ground. If either pin goes high or low, or if both pins go low, then both pins are pulled low and the output goes low. How-ever, if both pins go high, the output goes high.
(4) Internal Control -- failure of control or steering circuitry inside a device often has unpre-dictable effects. Generally, device outputs are stuck either high or low, but sometimes float between high and ground.
Page 2 Jan 05/01 3-1
HoneywellCOMPONENT MAINTENANCE MANUAL
PART NO. 964-0446
(5) Short -- between a point and supply Vcc or ground behaves like a device internal short. Connecting lines are either pulled high to Vcc or low to ground.
(6) Short -- between 2 points, neither of which is a supply or ground, causes a low output when either point is high or low, or both are low, but when both points are high, the out-put is high.
(7) Open Line -- a break in external lines causes device inputs or output to float, usually at approximately 1.4 to 1.5VDC.
(8) External Component Failure -- a fault in another device affects this one. Lines between devices may be stuck high or low, or may float, depending on the type of fault.
F. The HHDLU functional test in the Testing section provides the testing.

ILLUSTRATED PARTS LIST
1. Introduction CAUTION: ELECTROSTATIC DISCHARGE SENSITIVE (ESDS) ITEMS ARE SUBJECT TO DAMAGE BY
EXCESSIVE LEVELS OF VOLTAGE. REFER TO DOD-HDBK-263 FOR PROPER HANDLINGPROCEDURES.
A. The Illustrated Parts List (IPL) provides a breakdown of the equipment covered by this man-ual. All parts are listed in order of disassembly, showing relationships to higher and lowerassemblies, and are identified by corresponding index numbers on board-layout andexploded-view illustrations.
B. All items are assigned an item number. Parts listed but not illustrated are identified by adash -- preceding the item number.
C. For identification of detail parts and assemblies, the NOMENCLATURE column employs theindenture system. Each assembly is listed with its detail parts listed in the next indenturebelow and to the right. Conversely, the next higher assembly of any detail part may be deter-mined by its location in the indenture above and to the left.
D. Attaching parts immediately follow the part or assembly which they attach and have thesame indenture. They are preceded by the words ATTACHING PARTS and followed bythree asterisks * * *.
E. Effectivity codes (A, B, C, etc.) are assigned, and listed in the EFF CODE column, when twoor more similar assemblies are broken down in the same IPL figure. These codes show thata part or subassembly is used only on the assembly(ies) with the same effectivity code(s). Apart or subassembly with no effectivity code is used on all of the assemblies listed in that fig-ure.
Although the same effectivity codes (A, B, C, etc.) may be used in more than one IPL figure,there is no relation between the codes of one figure and the codes of any other figure.To determine end-item effectivity; i.e., on which end item a part, subassembly, or assemblyis used when multiple end items are listed, find the effectivity code(s) of the item in question.This leads to the assembly(ies) on which the item is used, to the Next Higher Assembly(NHA), etc., and subsequently, to the end-item figure and the end item(s).
F. Unless otherwise indicated by a vendor code number in parentheses following the part namein the parts list, all parts are either commercial standard, military standard, or Honeywellparts.
