1. Introduction

This document provides information on the use of the Honeywell terminal emulation program WinVIEWS. WinVIEWS, or

Windows Virtual Interface to the Enhanced Warning System, is a software tool used in troubleshooting and checkout of aircraft

installations of the Honeywell Enhanced Ground Proximity Warning System (EGPWS).

2. Effectivity

This users guide is effective for WinVIEWS Version 2.0, PN 998-2846-500.

3. Reference Documents

4. OverviewThe EGPWS provides an RS-232 test connection that can be used to access internal data from the EGPWS. In addition to internal

data, other items such as unit configuration and flight history can also be viewed using a personal computer (PC).

A PC terminal emulator program called WinVIEWS is used to access information in the EGPWS. WinVIEWS runs on any PC with

Windows 3.1 or higher and communicates with the EGPWS by a serial cable connection. WinVIEWS automatically configures the

communications port of the PC.

WinVIEWS has two basic modes of operation, Terminal Mode and Data Display Mode. Terminal Mode is used to send EGPWS

commands and receive data responses. Signals (data) can be seen in real-time using the Data Display Mode. Data Display Mode

can be used to assist in the system checkout when using an appropriate command file.

5. Loading WinVIEWS

WinVIEWS Version 2.0, PN 998-2846-500, is available on diskette free of charge from Honeywell Order Administration in Redmond,

Washington (phone 425-885-8917, fax 425-885-8988). WinVIEWS may also be downloaded from our Internet site, www.egpws.com

The WinVIEWS files (~ 727 K bytes) are included in the install diskette. These files may be zipped together into one self-extracting

zip file. The files contained are:

System files

_inst16.ex_, _isdel.exe, _setup.dll, _setup.lib, data.z, setup.exe, setup.ins, setup.lst, setup.pkg, uninst16.exe

Helper files

Gen_GTP.cmd a generic command file of ground test CVT Items

Gen_FTP.cmd a generic command file of flight test CVT Items

Readme.txt information fileWinVUser.doc This document

Using a PC running Windows 3.1 or later, create a WinVIEWS directory, and copy all the files to the PC. Unzip the files if

necessary. Run the SETUP.EXE file to install WinVIEWS on the PC. Follow the on-screen instructions.

6. Starting WinVIEWS

Verify that the serial port of the PC is connected to the RS-232 port of the EGPWS via a serial cable. Verify the EGPWS power is

ON.

Note For interface directly to the EGPWS front panel RS-232 port, see Section 4, Reference Document 704-2617.

Start WinVIEWS on the PC by clicking on the WinVIEWS icon. The program will automatically choose an open serial port.

Typically, this will be COM1 or COM2. Ensure the box labeled Automatically send command file after connect is NOT selected

Press Connect to continue.

Wait a few seconds while the EGPWS scrolls through the startup screen. If the > prompt doesnt appear, press CTRL and Z

simultaneously to establish communications between the PC and the EGPWS.

Note If the EGPWS power is cycled while WinVIEWS is running, communication between the EGPWS and PC will be lost.

Once the EGPWS has regained power, press CTRL and Z simultaneously to re-establish communications between the PC

and the EGPWS.

When started by this method, WinVIEWS enters the Terminal Mode where the user can send EGPWS commands and view signal

responses. Use the drop-down command menus or type a command (followed by the Enter key) to send the command. The

EGPWS will respond to the PC. Enter help or ? for a complete list of commands.

Note If the PC has infrared (IR) port capability enabled on the COM port, this will need to disabled prior to using WinVIEWS

on the PC.

Note At the initial Connect screen, if the box labeled Automatically send command file after connect is selected, WinVIEWS

will attempt to load the command file shown at the bottom of the dialog box. The target command file can be changed by

pressing the Change button, and browsing to find the command file. If the box labeled Enter Data Display Mode after

loading Command File is selected, WinVIEWS will attempt to enter Data Display Mode after loading the command file. It

is a good practice to leave the box labeled Delete current EGPWS signal list before loading Command File always

selected.

7. Terminal Mode

Terminal Mode is the primary mode of using WinVIEWS to query the EGPWS signals. While in Terminal Mode, the user receives

a command prompt > from the EGPWS whenever it is ready to receive a command. The user can enter a command by selecting it

from the drop-down Commands menu or by typing it in after the prompt. This command will be sent to the EGPWS. The EGPWS

will respond to the PC with the requested information.

This information can be viewed on the PC or recorded as a text file for later review.

While in Terminal Mode, it is also possible to send the EGPWS a list of signals from a command file or a list of commands from a

script file. Command files contain a list of signal names that are sent to the EGPWS so that the values can be viewed. Similarly,

script files contain a list of commands to be sent to the EGPWS for processing.

Short-cut keys are available to send frequently used commands such as Present Status (F7) or Self Test Level 1 (F8). The drop-

down menu lists the short-cut key.

7.1 Present Status

Usually it is best to begin by checking Present Status; type PS and press Enter, or simply press F7. An example is shown below

for a MK V EGPWS installed in a Gulfstream IV. The following text will appear on the PC.

Note If the text overruns one screen height, the message Press to Continue (Y/N) will appear at the bottom of the screen.Press Y to continue scrolling down.

7.2 Commands

See the drop-down Commands menu (Section 7.5.1.4) for frequently used commands. Below is an alphabetical list of the

commands most often used. Press CTRL-Rto repeat the previous command. To see a list of all commands, type HELP or ?, then

press Enter.

CXR - output CVT Item's value

Example CXR RawPitch1 will list current value of #1 Pitch source (in degrees)

Note: For a list of common CVT Items, see Honeywell document 060-4199-111, Current Value Table (CVT) Item Reference List fo

EGPWS

CXL - list matching CVT Items

Example CXL GPS will return all CVT Items with string GPS in their name

COV - overwrite CVT Item's value

Example COV TerClr 750 will set computed terrain clearance to 750 feet

Note: When using the COV command, the red COMPUTER FAIL LED on the EGPWS front panel will illuminate to indicate a

software value has been overwritten.

COD - clear overwrite of specific or all CVT Items

Example COD TerClr will return computed terrain clearance to normal processing

Note: When the COD ALL command is issued, the status LEDs on the EGPWS front panel will return to normal processing.

FHE - Flight history erase (will verify and reboot)

FHF - Output flight fault history

FHG - Output ground history

FHI - Output INOP history

FHS - Output status history

FHW - Output Warning history

ST - Perform SelfTest 1-6 (L=Long Level 1; C=Cancel)

VOI - Voice a word (if word unknown it will be spelled)

7.3 Script Files

Script files are files with *.SCR extension which contain a list of commands to be sent to the EGPWS. Script files can be created

using a text editor. A sample script file is shown below. This file will set the EGPWS position to near Seattle, Washington, at an

altitude of 12,000 feet, heading true north, with a groundspeed of 200 knots. The display range will be forced to 300 nautical miles:

COV PosUncert 0

COV TAWxRng1 300

COV TACAlt 12000

COV TALatude 47

COV TALngude 122

COV TATruHd 0

COV TATruTrk 0

delay 4000

COV TAGndSpd 200

The delay statement is not an EGPWS command and is not sent to the EGPWS. Instead, the delay 4000 command causes

WinVIEWS to wait 4000 ms (4 seconds) before sending the next command.

7.4 Command Files

Ground testing of EGPWS typically uses WinVIEWS in Data Display Mode to view and verify all EGPWS inputs. The EGPWS

inputs are defined by Current Value Table (CVT) Items. While in Terminal Mode, it is possible to send the required list of CVT

Items to the EGPWS for real-time display. This is called loading a Command file and must be done prior to using the real-time Data

Display Mode.

Command files are text files with the *.CMD extension which contain a list of CVT Items to be sent to the EGPWS. Command files

can be created using a text editor. Sample command files are typically found in an appendix to the applicable ground test

procedure. Sample command files for ground and flight testing are found on the WinVIEWS diskette.

A brief sample Command File is shown below:

RawRA1 VCF

RawBAlt1

AGS1Val F

SystemRNP C

The first string is the CVT Item (example RawRA1 is the raw radio altitude from the #1 source). After a space, the second string

contains a combination of the letters V, C, and/or F, signifying if the user wishes to examine the Value, Custom and/or Flag field of

the preceding CVT Item. Specifying no letters defaults to examining the Value field.

See section 7.5.1.1 below for further instruction loading Command Files. See section 8 (Data Display Mode) for further instruction

viewing signals loaded from Command Files.

7.5 Drop Down MenusThe following drop-down menus are available in Terminal Mode, but not in Display Data Mode.

7.5.1 File Menu

7.5.1.1 Load Command File (F1)

The Load Command File menu choice allows the user to load selected CVT Item into the EGPWS. A typical Windows dialog box

for loading files will appear. Use the Directories and Drives windows to select the location where Command Files are saved on

your PC.

It is optional whether to erase the current signal list before loading the command file, but erasing the current signal list is

recommended to avoid confusion. If desired, the user may also choose to have WinVIEWS go directly into Data Display Modeafter loading the command file. If this option is not chosen, the user can enter Data Display Mode using the drop-down menu

choice File/Enter Data Display Mode or by pressing F6.

When the command file is finished loading, an inquiry may appear asking if you wish to view the Error file. The Error file is a listing

of commands that didnt load. Usually these are CVT Items that dont apply to the current aircraft configuration. This is expected

when using the generic command files found on the WinVIEWS diskette. You can view these errors now by selecting Yes, or

answer No to view them later (an error.txt file is generated in the directory where the command file resides).

Note: If a Command File generates errors while loading, it can be modified to remove the offending CVT Items. Prior to

modifying a Command File, it is best to review the list of errors to see what CVT Items are unknown in the current

configuration. While some may be obvious (GPS signals in a non-GPS installation), the lack of expected signals may

indicate configuration strapping errors (i.e. Display signals unknown in installations that use terrain display). For a list of

common CVT Items, see Honeywell document 060-4199-111, Current Value Table (CVT) Item Reference List for EGPWS.

7.5.1.2 Load Script File

The Load Script File menu choice allows the user to load selected commands into the EGPWS (see section 7.3 for a discussion of

Script Files). A typical Windows dialog box for loading files will appear. Use the Directories and Drives windows to select the

location where Script Files are saved on your PC.

7.5.1.3 Show Last Command / Script File Errors

When a command or script file is sent to the EGPWS using WinVIEWS, any errors are written to a log file. Only the log from the

last processed command or script file is kept, and this log may be viewed using the File/Show Last Command/Script File Errors

7/25/2019 Users G

menu item. WinVIEWS displays the log using the Windows Notepad accessory. If your PC does not have Windows Notepad

installed, this command will not work properly.

7.5.1.4 Start / Stop Recording Terminal Log (F11)

While in Terminal Mode, it is possible to save the session to a *.TXT or *.LOG file for later viewing. Either of these files can be

viewed with most text editors, including Windows Notepad (provided the log is shorter than 64 Kbytes). The name of the log file

is specified using a standard Windows file open dialog box, when the recording is started using the File/Start Recording Terminal

Log menu item. Once a terminal recording log is started, it will continue until it is stopped with the File/Stop Recording Terminal

Log menu item or until WinVIEWS exits. An example follows (using the shortcut key F11):

1. Press F11 to open the log file

2. Set the file name and directory. Using the aircraft registration number with a *.TXT extension is recommended

3. Perform a Present Status by pressing F7 (press Y to answer all continuation messages)

4. Press F11 to close the log file

This method of recording data is especially helpful during EGPWS installation. It allows installers to record and save the installed

configuration, and is easily e-mailed to Customer Service Engineering should troubleshooting assistance be required.

7.5.1.5 Enter Data Display Mode (F6)

From Terminal Mode, the user may enter Data Display Mode by choosing the File/Enter Data Display Mode menu item or

pressing F6. If there are no CVT Items currently loaded, an error message will be generated on the screen, and WinVIEWS will

automatically return to Terminal Mode.

7.5.1.6 Set Data History File (F3)

When viewing data real-time in Data Display Mode, the data on the screen may be recorded. However, while in Data Display

Mode, the display may not be interrupted with a dialog box. Therefore, the data history file name and location must be set before

entering Data Display Mode, via the File/Set Data History File menu item. The base filename is entered using a standard

Windows file open dialog box. An example follows (using the shortcut key F3):

1. Press F3 to open the history file

2. Set the file name and directory. Using the aircraft registration number with a *.HST extension is recommended. Note that

the file name cannot exceed 8 characters in length, and the last two characters will always be truncated and replaced withnumeric characters (starting with 00). If the user tries to save the file as N1234AB.HST, the file will actually be saved as

N1234A00.HST.

3. Press F6 to enter Data Display Mode. The history file name and location will appear in the F4 command line.

7.5.1.7 Exit (ALT-F4)

This menu choice exits WinVIEWS. ALT-F4 will do likewise.

7.5.2 Edit Menu

7.5.2.1 Copy

In Terminal Mode, Edit/Copy (or CTRL-C) copies the highlighted lines of text to the Windows clipboard. This menu item will not

be enabled until text is selected.

7.5.2.2 Paste

In Terminal Mode, Edit/Paste (or CTRL-V) pastes the text from the Windows clipboard onto the end of the terminal window text.

This menu item will not be enabled unless there is text in the Windows clipboard.

7.5.3 View Menu

7.5.3.1 Toolbar

In Terminal Mode, View/Toolbar toggles whether the toolbar at the top of the terminal window is visible or not. When the toolbar

is visible, there is a checkmark next to the word Toolbar. The toolbar should be turned off in this version because it is mostly

unused. Future product versions may contain a toolbar with more functions.

7.5.3.2 Status BarIn Terminal Mode, View/Status Bar toggles whether the status bar at the bottom of the terminal window is visible or not. When the

status bar is visible, there is a checkmark next to the words Status Bar. The status bar contains a short text description of the

selected menu item, for some items. The right portion of the status bar also shows the state of caps lock, num lock, and scroll lock

keys.

7.5.4 Commands Menu

7.5.4.1 Present Status (F7)

Sends the PS command to the EGPWS, which returns information about the EGPWS current status. F7 is the short-cut key for

Present Status.

7.5.4.2 Add CVT Item

Invokes a dialog box that can be used to add one CVT Item to the currently loaded list. The value, custom, and/or flag fields for

the entered signal name can be selected by checking the corresponding check boxes. To add a CVT Item to the currently loaded

list, place the name of the CVT Item to be added in the box, and press the Add button. Press F6 to return to Data Display Mode to

view the added CVT Item.

7.5.4.3 List Selected CVT Items

Sends the cml command to the EGPWS, which lists all the CVT Items currently loaded.

7.5.4.4 List Available CVT Items

Sends the cxl command to the EGPWS, which lists all the possible CVT Items the user could add, based on the current EGPWS

configuration.

7.5.4.5 Delete All CVT Items

Sends the cmd ALL command to the EGPWS, which removes all CVT Items from the PCs current list.

7.5.4.6 Flight Warnings

Sends the FHE command to the EGPWS, which lists all the flight warnings.

7.5.4.7 Flight Faults

Sends the FHF command to the EGPWS, which lists all the flight faults.

7.5.4.8 Ground History

Sends the FHG command to the EGPWS, which lists all the ground history faults.

7.5.4.9 Self Test 1 6 (F8 for Self Test 1)

Sends the ST X command to the EGPWS, where X is 1 through 6. This runs an EGPWS self test. F8 is the shortcut key for Self

Test 1. For a description of Self Test levels 1-6, see the applicable Product Specification.

7/25/2019 Users G

11/14


Note Once a self test is started, the same selection source, either the cockpit switch or the RS-232 port, must be used to

conclude self test.

7.5.4.10 Self Test Cancel

Sends the ST C command to the EGPWS. This cancels a self test in progress.

7.5.4.11 Reset EGPWS and WinVIEWS

Sends a command to the EGPWS to reset the unit and also resets WinVIEWS.

7.5.5 Options Menu

7.5.5.1 Settings

The Settings dialog box contains two items:

Suppress Continue (Y/N) ? messages? - Checking this box sets WinVIEWS to suppress these messages and the page pause

that the EGPWS generates at the end of a page of text. These (Y/N) messages are seen during replies to commands sent in

Terminal Mode.

EGPWS Data Sampling Interval - Entering a value in milliseconds sets the EGPWS data sampling rate. This value must be a

multiple of 100 milliseconds. The data sampling rate determines how often the EGPWS updates CVT Items when in Data Display

Mode. This sample rate also affects data recording. Fast sample rates (100 ms) can be used to capture fast transient conditions,

and result in better data resolution. Start with a setting of 500 ms for Pentium PCs and with 1,000 ms for 486 PCs.

7.5.5.2 Terminal Font

This menu choice allows the user to set the font (type and size) used in Terminal Mode. The font is selected using a standard

Windows font selection dialog box and the choice is saved in the WINVIEWS.INI file for future program use. Typically the font

will be set to Courier New, font style Regular, font size 10. Set the font to a larger size for easier reading. Set the font to a

smaller size to fit more information on a single screen.

Note: If the font size is set too high, all information may not be displayed on the PC screen. In this case, use the scroll bars to

view missing CVT Items or decrease the font size. In cases of extremely large font size (larger than 3000) no data will be

displayed, reduce the font size to 10-12.

7.5.5.3 Data Display Font

This menu choice allows the user to set the font used in Data Display Mode. The font is selected using a standard Windows font

selection dialog box and the choice is saved in the WINVIEWS.INI file for future program use. Typically the font will be set to

Courier New, font style Regular, font size 10. Set the font to a larger size for easier reading. Set the font to a smaller size to fit

more CVT item information on a single screen.

Note: If the font size is set too high, all CVT Items loaded may not be displayed on the PC screen. In this case, use the scroll

bars to view missing CVT Items or decrease the font size. In cases of extremely large font size (larger than 3000) no data

will be displayed, reduce the font size to 10-12.

7.5.6 Help Menu

7.5.6.1 Contents

This item opens the WinVIEWS help file to the table of contents.

7.5.6.2 About WinVIEWS

8. Data Display Mode

Data Display Mode is a real-time display of selected signals (data) in the EGPWS. The user interface in this mode is limited to

function keys (i.e. F6, F10) rather than the drop-down menus and dialog boxes used in the Terminal Mode. The available

function keys are listed on the screen during Data Display Mode.

As new values are received from the EGPWS during Data Display Mode, an airplane symbol in the lower right corner of the screen

does an eight-point roll. The aircraft symbol serves as a confidence indicator for RS-232 communication to the EGPWS. While in

Data Display Mode, it is possible to record the changing signal values in a file with a * .HST extension. These recordings use a

unique compression format and can be post-processed using special Honeywell tools. These special tools will convert the HST

file into a Microsoft Excel spreadsheet, with each CVT Item displayed in a column. HST files can be simply viewed with Microsoft

Wordpad. By this method, only CVT Items that change from the previous time interval are written to the file.

Before entering Display Data Mode you must load a command file. The command file is loaded while in Terminal Mode using a

drop-down menu or function key (F1). See section 7.5.1.1 for more details.

8.1 Recording Data History

The data viewed in Data Display Mode may be recorded for later analysis. A history file with a * .HST extension is used to log the

data. These history files use a special compressed format and must be processed by Honeywell using special tools.

The name and location of the history file must be entered in Terminal Mode (before entering Data Display Mode). See section

7.5.1.6 for more details.

The recording is started with the F4 key and stopped with the F5 key. The last two digits of the file name can be incremented using

the F10 key. When a data history recording exceeds 1.44MB (the size of a high-density 3.5 disk) the last two digits of the file

name will automatically be incremented (from 00 to 01, from 09 to 10, etc.). Also, events can be dropped in the file during recording

using the F9 key, to aid in finding a particular section of the file later.

8.2 Commands

8.2.1 F4 - Start Recording History

Press F4 to begin recording data (CVT Item values) in a data history file with a * .HST extension. During data recording, a new file

may be started by pressing the F10 key. When a data recording is started, the F4 command line will change from Start recording

data history in to RECORDING DATA HISTORY in.... If a data history file is incremented (automatically or by pressing F10)

during data collection, the original file is closed, the file name is incremented, and the recording continues in the new file.

8.2.2 F5 - Stop Recording History

While in Data Display Mode and while a data history recording is in progress, the recording may be stopped by pressing F5. It is

possible to make multiple recordings in the same file by starting and stopping the recording. When a data recording is in progress,

and the recording is stopped, the F4 command line will change from RECORDING DATA HISTORY in... to Start recording data

history in.

8.2.3 F6 - Exit Data Display Mode

While in Data Display Mode, the user can return to Terminal Mode by pressing the F6 or ESC key. If data history recording is inprogress at exit, the data history recording will be stopped automatically.

8.2.4 F9 - Drop Event Flag

While in Data Display Mode and recording the data history, it is possible to drop markers in the data history file, to later

correlate data to an event (i.e. dropping a marker when the plane banks steeply, etc.). Pressing F9 drops an event flag, and when

this is successful, the event flag number in the line at the bottom of Data Display Mode increments by one.

The event flags dropped in the data history file are of the form: Event Flag n @ t where n is the event flag number and t is the

time in ms since recording start when the event flag was dropped.

If dropping an event flag is unsuccessful for some reason, the PC speaker will beep and the event flag number will not increment.

8.2.5 F10 - Roll Data History FileIn Data Display Mode, the F4 command line displays the name and location of the data history file. This file name can be

incremented by pressing F10. The F4 command line will show the new filename after a successful increment. A data history file

can be incremented while a recording is in progress. This causes the original file to be closed and a new file with the incremented

name to be opened.
