INTRODUCTION
The Yellowjacket™ is an 802.11b/g analysis system consist-
ing of an HP iPAQ PocketPC® coupled with custom hardware
and software designed and manufactured by BVS. This system
contains a variety of features to analyze 802.11b and 802.11g
networks including spectrum analysis over all 14 channels
(2.4 GHz), a list of AP’s and/or stations over all 14 channels
and packet-error rate information for each individual MAC
address. The Yellowjacket also contains a security feature to
warn the user of possible unauthorized AP/ STAtions in the
area based on a list of authorized MAC addresses. The data
from a Yellowjacket may be logged into resident memory,
CF or SD storage card for transfer to a desktop PC at a later
time and then be converted from binary to ASCII using BVS
Chameleon™ software. YellowjacketPLUS is identical to stan-
dard Yellowjacket in every way accept for the addition of GPS
receiver hardware and PocketPC software screens. Except
for the GPS antenna jack on the receiver, all Yellowjacket
802.11b/g models look identical.
Yellowjacket receiver (top view) has an SMA male connector
for the supplied antenna. This manual contains operational
procedures to get the user up-and-going right out of the box.
For any details regarding the iPAQ, users should read all
materials from Compaq/HP and contact them.
STARTING UP YELLOWJACKET
Power up your Yellowjacket by pushing power button in upper
right corner of unit. This power will automatically power up
the Yellowjacket receiver also. When you power down the
iPAQ, (push the power button on the upper right quickly-
holding this button will also toggle the backlight on and off)
your Yellowjacket receiver will also shut down. Connect the
included antenna to the SMA connector and remove the stylus
by pulling it up. Use your stylus to tap onto the Windows® icon
in the upper left corner. Choose Yellowjacket in the pulldown
menu. Data may be transferred to a PC via the IrDA window
or USB or serial connection. Install Yellowjacket software by
connecting your iPAQ to your PC and inserting included BVS
software CD-ROM into PC to begin installation. You may also
use the provided Compact Flash Installer card. Be sure to turn
off any internal WLAN or Bluetooth in your iPAQ before using
your Yellowjacket.
WARNING FOR USERS WITH BUILT-IN WIRELESS
(you must disable your iPAQ’s Bluetooth and WLAN)
1. Press the START button on the upper left hand side
of the touch screen.
2. Click on the “iPAQ Wireless” folder.
3. Click on the “Wireless Control” program.
4. Click on “All wireless features OFF”. The icons for
Bluetooth and WLAN will have red backgrounds when
disabled.
Your iPAQ can be reset using 2 different methods.
If Yellowjacket software loses communications with
Yellowjacket hardware, perform a soft reset with your
stylus by pressing the reset button on the back left cor-
ner just below the battery door. Perform a hard reset by
holding in the two outer buttons for at least 10 seconds
while performing a soft reset. Warning! Hard reset

YELLOWJACKET ACCESSORIES
Your Yellowjacket includes the following accessories: anten-
na, 2 sets of AA (Ni-MH) removable batteries (8 total), Simply
insert depleted batteries into charger and plug charger into AC
outlet. See top of charger for LED status indicator lights (see
end of manual for charger specs). Approximate charging time
for 4 Ni-MH batteries is just over one hour. Run time is just
over two hours. Yellowjacket uses common AA battery cells
found in any convienence store. Ni-Cad, Alkalines, Ni-MH and
Li-Ion cells may all be used. Yellowjacket does require 4 AA
cells with at least 1500 mAh per cell. BVS supplies 2 battery
sets (8 Ni-MH battery cells total) to get users working right out
of the box. Ni-MH cells are recommended for best performance
from your Yellowjacket. Batteries that are warm or hot to the
touch (from constant usage or warm ambient temperatures)
will take longer to charge than batteries of a normal tempera-
ture. Contact BVS for new Ni-MH battery packs. Expect over
500 cycles from each Ni-MH battery or battery pack.
If the Yellowjacket CF or SD Backup Installer
card has been included, it may be used to log
data files onto. It can also be used on iPAQs
that have never been initially set up at the
BVS factory, have had files erased or dam-
aged in the ROM or after a hard reset has been
performed on an iPAQ. Yellowjacket software
that has been erased/lost from RAM may be
restored at anytime by accessing the “install”
file from the SD Card or Storage Card directory.
Always make sure batteries are fully charged
when doing any software installs. Yellowjacket
software that has been erased from RAM may
be restored at anytime by accessing the “rein-
styj” file from the \\iPAQ File Store\\My Device
directory.

Starting Up Your Yellowjacket
Unpack and assemble your Yellowjacket unit as shown. Slide the iPAQ case onto the Yellowjacket and slide your iPAQ computer
into the iPAQ case. Remove the Compact Flash cover and install the Compact Flash serial cable. The Compact Flash serial cable
is the communication link between the Yellowjacket receiver and the iPAQ. Connect both the Yellowjacket and iPAQ to external
power as shown with the “Y” power cable.
Power up the iPAQ by pushing the power button in the upper right corner of the iPAQ. Connect the appropriate frequency antenna
to the SMA male antenna input. iPAQs shipped by BVS are optimized for the Yellowjacket. If you are using your own iPAQ, see
the optimization section to set up your iPAQ.
iPAQs supplied by BVS have the Yellowjacket software pre-installed. If you need to install the Yellowjacket software, see the
software installation/re-installation section.
Tap the windows Start icon in the upper left corner and then choose Yellowjacket in the pulldown menu. If the Yellowjacket does
not appear in the pulldown menu, tap on the “Programs” folder. Tap on the Yellowjacket icon.
Running the Yellowjacket software will power the Yellowjacket receiver.
If the Yellowjacket software loses communication with the Yellowjacket, perform a soft reset by pressing the iPAQ’s reset button.
If communications problems persist, perform a hard reset by holding down the two outer buttons on the front of the iPAQ while
holding in the soft reset button. Remember, hard resets erase all data collected and software installed so backup all data and

Getting Started
To start the YellowJacket 802.11b/g software:
1. Press the Start button on the iPAQ.
2. Press the PROGRAMS option.
3. Press the “Yellow Jacket BG” icon (usually at the bot-
tom of the alphabetized list).
4. Tap anywhere on the screen when the splash screen
appears as shown below.
Note: This splash screen may vary slightly depending upon the
Yellowjacket model.
Main Menu
The main menu of the YellowJacket software contains option
buttons in the main viewing area and a series of toolbar
options. The main viewing area is shown below. There are
five choices in the main viewing area. You may choose spec-
trum analysis, which enters a spectrum analyzer-type screen
that will show all RF being received within the range of the
receiver. This mode also allows for zooming in to a particular
channel.
The next option is the access point screen. This will allow
the user to view individual access points (and stations) being
seen by the receiver and then to proceed to an individual MAC
address screen for closer examination.
The third option is the “WISP Antenna Alignment” screen.
This screen allows the user to select an access point to focus
on for antenna alignment.
The fourth option is the security screen. This screen allows the
entry and maintenance of authorized and unauthorized access
point lists. This screen is useful in determining if there are
any rogue access points in the area that can be potentially
invasive to an existing network.
The fifth option is the network utilization screen. This screen
shows the system utilization for each channel.
The sixth button shown takes the user to the GPS receiver
screen displaying LAT,LON,ALT and satellite information. This
Note: Users should normally see genuine
firmware and serial numbers on this screen
when Yellowjacket is functioning properly.
If your firmware and serial number appear
as 0.00 and XXXXXX, then the iPAQ soft-
ware is not communicating properly with
the Yellowjacket receiver. Try troubleshoot-
ing procedures found in this user’s manual.

button will only appear on YellowjacketPLUS models.
The toolbar gives the user more options on every screen.
The first icon has three colored circles. Using this option will
always return the user to the main menu.
The “record” button is for logging a data file. The “stop” but-
ton is for terminating the logging of data.
The fourth icon represents a camera. This option takes snap-
shots of the current screen for later viewing.
The fifth and sixth icons are arrows pointing upward and
downward. These options have different uses depending on
the currently active screen. For instance, on the access point
screen, the arrows are used to flip the current page of access
points.
The “checkmark” icon is used to increment the current marker
number. This starts at 1 when the software is started. It will
increment by 1 on every touch. This is of use when a file is
being logged. Any change in value will be recorded in the log
file.
The icon with the letters “ABCD” enters the system options
screen. There is an option to report any unauthorized MAC
addresses. This is discussed further in the “SECURITY” sec-
tion later in this manual. The “Enable Dolphin port” option
only applies to YellowjacketPLUS receivers with the internal
GPS receiver installed at the BVS factory.
The question mark icon reveals the application about box.
Spectrum Analysis
The spectrum analysis feature of the YellowJacket allows a
user to view any RF signals that is received by the receiver.
It uses frequency for the X-axis and RSSI (received signal
strength indicator) in dBm on the Y-axis.
Both the full spectrum and the single channel screens have
the same options for the most part. There are three available
traces, red, blue, and green traces. Only one trace can be
active at any one time.
Each of the three traces can be made visible by pressing their
respective “visible” buttons. The active trace can be peak
held by pressing it’s “hold trace” button.
Use the “marker to peak” button to move the diamond marker

Page 7
to the current highest dBm valued point. Use the “marker to
center” button to move the diamond marker to the center of
the currently displayed section.
There are also buttons for moving the diamond peak mark to
the left or right in the currently displayed screen.
Each spectrum screen displays information regarding the cen-
ter frequency of the screen as well as the span in MHz. The
current marker position and value is also displayed.
Full Spectrum
The full spectrum screen is the first one entered when going
into the spectrum analysis option. This screen shows RF
energy in dBm over all 14 channels seen by the receiver. Each
vertical section represents 10 MHz.
To “zoom in” on a single channel, simply tap one of the num-
bered boxes. For example, clicking on the channel 4 box will
zoom in to channel 4.
Single Channel Spectrum
The single channel screen displays RSSI valued data within
the channel specified. To return to the full spectrum mode,
press the “SURVEY” button.

Page 8
Access Point List
The access point list screen provides the user with a list of
access points that are seen by the receiver. The user can then
“zoom in” on a particular access point for further analysis as
well as for pinpointing the AP’s location.
MAC List
The MAC list is shown on the main access point list screen.
This list shows each of the MAC’s seen and other information
on each of them. This information includes such fields as the
channel number associated with each access point, the MAC
address and SSID of the access point, as well as the RSSI
value in dBm of the access points.
A note on the channel number. If the particular MAC address is
a client, the channel number will be what the receiver is set to
at the time. If the receiver sees the access point to which the
client is talking, the channel will be readjusted to the proper
transmitting channel. A gray background box signifies that the
channel number is that which was observed. The lack of the
gray background denotes that it is the actual channel that the
client is on.
The RSSI value may appear as a couple of dashes (--) if:
1. The MAC address is an access point.
2. The channel that the access point is truly on has not
been reached in the survey yet.
The YellowJacket will only report RSSI values from access
points when it is from the actual channel from which the AP’s
are transmitting.
Also shown is the time elapsed since the last packet received
by each MAC. This is signified by the “TE=#” next to the MAC
address. Below this is an indicator signifying whether or not
this particular MAC address is related to an access point. If
“WEP” appears next to this, WEP encryption is detected.
The color of the information text for each access point will
change as the RSSI value increases and decreases. The scale
of the colors is shown on the top of the list. White is the stron-
gest value while red is the weakest. It is loosely based on
the colors of stars, white being the hottest and red being the
coolest.
Also, there may be multiple pages of the MAC list. To flip
between pages, use the up and down arrows provided on the
bottom of the screen in the toolbar.

Page 9
To look at one particular MAC address, simply tap on the box
containing the MAC address of interest.
Single MAC Address Mode (Locator Mode)
When a single MAC address is selected, the locator mode
screen appears. This screen has individual MAC address
information as well as a visual and audio representation of
proximity to the access point.
As the signal from the access point becomes stronger, the
audio effect of a submarine ping becomes higher in pitch.
Selecting the “DF Sound Off” button on the screen will mute
this audible sound. This mode is even more useful when
coupled with a directional antenna that would allow the user
to “home” in on the transmitted signal more efficiently.
The information provided on the locator screen includes the
MAC address and the SSID, as well as the channel on which
the access point is transmitting.
The packet error rate (PER) is displayed next to the SSID. This
is the overall PER for the last 200 packets received.
The RSSI level is displayed as a numeric value in dBm, as
well as a in a bar graph format and a temporal display.
Below the RSSI readings is a table relating packets received to
their data rates. Information such as kilobytes received, pack-
ets received, and utilization percentage are displayed.
WISP Antenna Alignment
The WISP Antenna alignment screen allows the user to select
a MAC address from a list or enter one manually for setting up
an antenna. If the MAC List screen has been entered recently,
the list box will have a number of MAC addresses to choose.
Also, a MAC may be entered separately in the edit box.
After choosing the MAC, the user will then see a screen with
a gauge that shows current signal strength and allows for a
peak hold. This peak hold can be reset at any time using the
“RESET PEAK” button.
Also, the temporal and bar RSSI displays are on the bottom of
the screen. Using a direction-finding antenna with this screen
is a fast way of locating the direction of the required signal

Page 10
from the MAC in question.
Security
The security screen allows for entering and maintaining of
authorized and unauthorized access point lists. This is a
feature that is used for determining if there are rogue/hostile
access points within striking distance of the network.
Checking the “check for unauthorized AP’s” option in the
option screen enables the security feature.
Authorized List
The authorized list is a list that contains the MAC addresses
of access points that are authorized to broadcast in the area
to be concerned. This list can be created one of three ways.
The first way is by entering MAC addresses in the topmost edit
field on the security screen. Then the “ADD” button is pressed
to add the address to the list. The next method is to retrieve
a previously saved list or a list that has been created on a PC
or laptop.
The final method is by pressing the “GENERATE AUTHORIZED
LIST” button. This may be pressed after leaving the
YellowJacket in the access point screen for a period where all
access points have been seen. All of these MAC addresses will
be moved into the authorized list.
This list can be saved to RAM by pressing the “SAVE” button.
This list can be cleared by pressing the “CLR” button next to
the list box.
The input file format for the authorized MAC list is as follows:
It is an ASCII file separated by CR/LF’s. The first line is the
number of addresses in the list. Then each MAC is on a sepa-
Unauthorized Warning
When Yellowjacket detects any AP that is
not included in the Authorized list, an audi-
ble warning beep will be heard. Remember
that Yellowjacket will continue to sound off
the alarm each time any unauthorized AP is
detected until it is placed in the Authorized
list by the user. Check your Options Screen
to turn this security alert ON or OFF.

After creating this file, it may be imported into the Yellowjacket
software by using the ‘Retrieve’ option.
Unauthorized List
The unauthorized list is populated when the security feature
is turned on via the option screen. Any MAC addresses seen
and demodulated by the receiver which are not in the current
authorized list will be flagged and inserted into the unauthor-
ized MAC address list.
Items in this list can be saved or retrieved to/from RAM by
pressing the “SAVE” or “RETRIEVE” buttons.
If the MAC addresses in the unauthorized list are wished to be
authorized, simply select the entry in the list box and press the
“AUTH” button.
This list can be cleared by pressing the “CLR” button next to
the list box.
Network Utilization
The Network Utilization screen shows the utilization seen by
the YellowJacket for each of the 14 channels. The view can be
switched from 0-100% to 0-10% to 0-1%.
Data Recording
When the “record” button icon is pressed from the toolbar at
the bottom of the screen, the user will be prompted for a file-
name. This filename will be used to store collected data for
later conversion by Chameleon WLAN.
The data is stored in a compact proprietary binary format. The
YellowJacket will store data as it received from the hardware,
depending on the currently active screen. If the spectrum
screen is currently active, spectrum data will be stored. If the
access point screen is currently active, access point informa-
tion will be stored.
Page 11

Page 12
To save the collected data, press the “stop” button icon. To
view the size of the log file while still logging, simply return to
the main menu screen.
WARNING! : Make sure that the “stop” button is pressed to
avoid the loss of data saved.
Markers
There is a marker number associated with logged data records.
When the checkmark button is pressed on the toolbar, this
marker number is incremented. This can be useful when need-
ing to mark a specific point in time for later post-processing.
Snapshots
When the camera icon is pressed from the toolbar at the bot-
tom of the screen, a snapshot of the currently viewable display
is taken. The snapshot can be saved as a JPEG format picture
(just like a digital camera) for viewing at a later time or for
importing into documents and reports. As an example, the
images of the YellowJacket screens shown in this section of
the manual were saved using this option.
Data Conversion using Chameleon (YellowJacket Edition)
Data that has been logged by the YellowJacket is stored in a
proprietary binary format. It can be transferred to a PC or lap-
top. Once on the PC or laptop, the Chameleon (YellowJacket
Edition) utility application can be used to convert the binary
data into an ASCII-readable format that can be imported into
spreadsheet applications such as MS Excel or other applica-
tions that accept ASCII-delimited data.
YellowjacketPLUS GPS Status
The GPS screen of the Yellowjacket Plus provides position and
timing information from the Global Positioning System of sat-
ellites. The Motorola GPS receiver provides accurate informa-
tion after synchronizing with at least 3 of the 24 satellites.
The Yellowjacket Plus must have a clear view of a good por-
tion of the sky in order to communicate with the GPS satel-
lites. The GPS receiver should lock within a few minutes. The
only exception is when the unit is turned on in a new area. If
the receiver was last turned on in California and now in New
Jersey, the GPS receiver could take up to an hour to lock.
The status bar at the bottom of the Yellowjacket Plus screen
shows the current date and time (Greenwich Mean) as well as

the current latitude and longitude in decimal degrees. There
is also a separate GPS screen which shows satellite informa-
tion.
The GPS information is stored in the log file when enabled for
later conversion by Chameleon. Each record will be tagged
with GPS information if so desired.
If you require GPS time-stamping with your 802.11b/g mea-
surements and your Yellowjacket does not display the GPS
screen or the main menu screen does not show a bottom GPS
data line similar to this:
Ask about our internal GPS option to upgrade your
Yellowjacket.

Charging System
The Yellowjacket has 2 different battery sources that need charging
power. There is an internal battery for the Pocket PC and removable
batteries for the receiver module. The 4 AA Ni-MH receiver batter-
ies may only be charged using the supplied fast charger or another
comparable Ni-MH charger. The Compaq iPAQ internal battery may
be charged by either plugging in the supplied power transformer or
by inserting the iPAQ PDA into the supplied charging / data transfer
cradle. The BVS supplied charger will power the Yellowjacket receiver
AND power and charge the iPAQ PDA. Batteries for the Yellowjacket
receiver (4 AA cells) must be charged in the provided charger. See
Compaq’s documentation for complete charging instructions.
Troubleshooting
Replacing Batteries
If your Yellowjacket or Hive has difficulty connecting or col-
lecting data and you have verified the iPAQ is fully charged,
then you may need to change your AA Ni-MH batteries out for
fresh ones. To access batteries under iPAQ:
1. Slide iPAQ back and away from antenna end of receiver.
Be sure not to pull too hard on the cable in any way. NEVER
remove the Compact Flash connector from the iPAQ sled
unless troubleshooting for connectivity issues.
2. Flip over iPAQ exposing the battery compartment on the top
of the BumbleBee receiver.
3. Change 4 Ni-MH AA batteries for fresh Ni-MH batteries and
repeat steps above in reverse order.
4. When troubleshooting connectivity issues, be sure to
GENTLY remove the Compact Flash serial adapter card from
the iPAQ. Slowly slide the card out holding it by the very top of
the card and NOT the cable. Be sure it is seated properly and
slowly slide it back into the iPAQ’s CF housing.
• Cannot Open Com Port or System Not Responding – Try
restarting the application. If the system locks up completely,
press the small reset button located at the back of your iPAQ.
See HP’s usage instructions for more info on performing a
hard reset.
• Yellowjacket software is missing or corrupted -
Re-install your Yellowjacket software.

TIPS
BATTERY LIFE
Yellow Jacket™ and Yellow Jacket Plus receivers use 4 or 5 Ni-MH long-lasting “AA Cells”.
1. Ni-MH batteries do not charge to full capacity the first time they are charged.
2. Ni-MH batteries do not charge to full capacity the first time they are charged after a long period of inactivity. or after a long
period of non-use.
Cause:
When charging Ni-MH batteries for the first time after long-term storage, deactivation of reactants may lead to increased
battery voltage and decreased capacity, (which causes premature termination of charging). Because batteries are chemical
products involving internal chemical reactions, performance deteriorates with prolonged storage. This is normal in Ni-MH bat-
teries.
Resolution:
Ni-MH batteries may not charge to full capacity the first time they are charged, or after a long period of inactivity.
The first-time charge of the Ni-MH Rechargeable Battery Pack should take approximately 2 hours. If the charger indicates a
full charge, in less than 2 hours, repeat the charge cycle as follows:
First-time Charge:
1. To begin charging, provide power to charger and insert NI-MH batteries.
2. When the charge is complete, remove the batteries from charger and place back in after several seconds.
3. Repeat steps 1 and 2 three or four times or until the combined charge time is 2 hours.
Subsequent charges of the W-LAN Ni-MH Battery Pack will not require multiple charging cycles unless left uncharged for a
long period of time (greater than 2 months).

In the PocketPC’s OS, choose Settings and then
choose System settings at the bottom. Select the
battery icon for Power Settings to access this
screen. These power settings come unchecked
from the BVS factory to ensure Yellowjacket soft-
ware runs optimally. Power must remain on during
logging or else data might be corrupted.
NEVER LEAVE THE IPAQ ON FOR EXTENDED TIMES (10 HOURS OR GREATER)
WITHOUT EXTERNAL POWER. ALWAYS SAVE ANY DATA AND THEN TURN OFF
IPAQ (TOP RIGHT POWER BUTTON) WHEN NOT IN USE. NOT DOING SO WILL
RESULT IN DAMAGE TO THE IPAQ’S INTERNAL BATTERY.
NOTE: In order to prevent the Ipaq from freezing when running
YellowJacket software (therefore rendering the power button useless),
make sure to:
1. ALWAYS leave the checkboxes in the SETTINGS/SYSTEM/POWER
screen unchecked. Power-save mode will lock up the application due
to the fact that the application is stopped while communicating with
the hardware..
2. Make sure that the battery level on the Ipaq remains above 40%.
The serial card interface may cease to operate when the battery level
is under 40%.
To resolve the freeze, simply press the soft reset button on the bottom
of the Ipaq with the stylus.

SOFTWARE INSTALLATION
YELLOWJACKET SOFTWARE INSTALLATION FROM A SECURE DIGITAL (SD) CARD
Yellowjacket software comes pre-installed on your iPAQ, but as a courtesy, BVS includes a 128MB SD card
containing a Yellowjacket software installer should you provide your own iPAQ or lose the factory installed
files. This SD card may be used to store Yellowjacket data or other data.
Remember you must switch “lock” tab on side of SD card to “unlock” before storing or erasing any data.
To install the YellowJacket application from the SD card provided in the YellowJacket package, complete
the following steps:
1. Insert SD card into the SD slot on the top of the iPAQ.
2. Using the stylus, tap on the “Start” button on the top of the screen.
3. Tap on “Programs” near the bottom of the menu.
4. Tap on the “File Explorer” folder.
5. Make sure that the shaded area on the top of the File Explorer says “My Device”. If not, use the
upside-down triangle next to the text to choose “My Device”.
6. Tap on “SD Card”.
7. Make sure that the shaded area on the top of the File Explorer says “SD Card”. If not, use the
upside-down triangle next to the text to choose “SD Card”.
8. Choose your Yellowjacket receiver and iPAQ model for installation and tap on “install”.
9. When the message “Installation is Complete” appears, you have successfully installed the applica-
tion.
The YellowJacket application will be accessible by tapping on “Start” and then “Programs”. Scroll down
to the bottom and the YellowJacket application icon will appear.
DRIVER INSTALLATION
The 24xx model iPAQ needs an updated driver for the Quatech serial card which interfaces to your BVS
product. The driver installation program can be found in the “driver” directory of your product CD. Run this
executable from your PC while the iPAQ is connected via ActiveSync. After installation, soft boot the iPAQ.
Your product should be ready to go. Symptoms of an iPAQ needing this driver include loss of communica-
tion in a high-speed data transfer mode (such as spectrum on YellowJackets and Bumble Bee).
SURVEYING
While surveying, Yellowjacket achieves the most accuracy when antenna is at a vertical 90 degree angle
and completely perpendicular to the ground or floor as shown below.

Chameleon (YellowJacket Edition)
PC Application
The Chameleon application converts data logged by the YellowJacket into an ASCII delimited file for use in
post-processing. The data converted is based on correlation records collected in the measurement mode
of the iPAQ YellowJacket Receiver Interface.
To convert a file, use the following steps:
1. Copy the log file off of the iPAQ and onto your desktop or laptop.
2. Run the Chameleon application.
3. Click BROWSE on the Input File line to choose a file to convert.
4. A default output filename will be created. Change if needed.
5. Choose which fields you wish to have in the output file.
6. Choose the delimiter to place between fields.
7. Choose whether or not you would like a header record with titles for each column.
8. Press the CONVERT button.
The progress bar will monitor the progress of the conversion.
