Revision 1.2 (Confidential) 3 www.national.com

1.0 User Interface

The National Semiconductor WebPAD™ s ystem’s tablet
user interface is simple and easy to use. It consists of an
interactive touch screen, scroll pad, and several user-con­figurable buttons. Speakers and a microphone are built in.
Additionally, several ports have been added to the side of
the tabletto allow for connectivity to USB devicessuch as,
an external keyboard,headphones and an external micro-

Geode™ SP3GX01

phone.
The main way to interact with the tablet is through the

touch screen. Links and menus are accessed by touching
the screen directly over their titles. Additionally, the touch
screen is sensitive enough to allow for handwriting recog­nition software to be used as a means of inputtingcharac­ters. The touch screen on the tablet works with any type of
pointer, from a stylus (included) to the simple touch of a
finger.

All of the buttons on the tablet, including the scroll pad,
are user-configurable, except the power button. The user
can change the definition of the buttons by entering the
system configuration mode (see section 2.0 "System Con­figuration"). Some of the buttons suggest clearly defined
operations, like the scroll pad, but the definitions are
changeable.

To input text, whether for an email, search criteria, or to
enter a URL, a virtual keyboard is available. The keypad

works the same as a normal keyboard and is accessed
from the QNX menu button or the Virtual Keyboard task
box at the bottom of the screen. The user touches the
screen just above the desired key and the letter appears
next to the cursor.

1.1 GRAPHICAL USER INTERFACE

When the tablet finishes booting, the graphical user inter­face (GUI) is started, as shown in Figure 1. The GUI con­tains a window area and a task bar. The background of
the window area contains an application launcher. Touch­ing either the icon or button beneath the icon invokes the
desired application. When applications are invoked, their
windows reside in this area.

The task bar contains a menu button and two icons in the
lower right corner for the vir tual keyboard and RF link sta­tus. The menu buttonis labeled “QNX” and offers the user
another method of launching applications. To use the
menu, touch the QNX button and then the desired appli­cation.

Touching either of the icons in the lower right corner starts
the corresponding application. A task box then a ppears
on the task bar (see sections 1.1.2 "RF Link Icon" and

1.1.3 "Virtual Keyboard Icon").

1.1.1 QNX Menu Button

Touch the QNX pop-up menu button to view the menu of
available applications. To invoke an application, simply
touch the name of the application.

1.1.2 RF Link Icon

The RF Link task displays the status of the radio link.
Selecting the icon on the task bar invokes the Link Status
application, showing the user the strength of the radio sig­nal from the base station (see section 1.5.4 "Link Status".
This icon indicates whether the RF link is up or down.

1.1.3 Virtual Keyboard Icon

Touching the Virtual Keyboard icon invokes the software
keyboard which allows the user to interact with the sys­tem. The soft keyboard is the main method of entering
URLs, responding to emails, etc. when no external
devices are attached.

1.2 LEDS

The tablet contains two LEDs (one amber and one green).
The amber LED is on the left side of the tablet, just above
the two user-defined buttons. It is a charge indicator. If the
LED is on, the battery is fully charged. If the LED is blink­ing, the battery is being charged. If the LED is off, the sys­tem is running off the batteries.

The green LED is on the right side of the tablet, just below
the power button. It is a status indicator. If the LED is on,
the tablet has been powered up.If the LED is blinking, the
batteries inside the tablet are low on power. If the LED is
off, the tablet has been powered off.

Geode™ SP3GX01

Scroll pad buttons are also user-defined. At their default
settings, the buttons are used to scroll around in web
pages. Pressing one of these buttons scrolls the screen in
that direction. The user can reconfigure these buttons but
it is not recommended. These buttons have a built in
repeat function, therefore, if they are reconfigured, the
function may be initiated multiple times with each press of
the button. Refer to section 2.2 "Buttons Configuration
Options" for details on configuring the user-defined and
scroll pad buttons.

1.4 RESET BUTTON

The tablet also contains a recessed reset button, located
on the left edge. This button is used to perform a hard
reset to the system which puts the system into a known
reset state. This should only be used if all other attempts
to remedy any problems have been exhausted.

1.5 APPLICATIONS

Applications range from a web browser and email reader
to MediaPlayerand touch screen calibrator. Each applica­tion has its own function.

Table 1 summarizes the available applications and their
access mechanisms. The subsections that follow provide
descriptions of each of the applications.

1.3 BUTTONS

The tablet has sevenbuttons:

• One power button

• Two user definable buttons

• Four buttons that form the scroll pad
The power button is in the upper right hand cor ner of the

tablet. To tur n the system on, simply press the power but­ton. The system will remain powered on until the button is
pressed again.

The two user-defined buttons are on the left side of the
tablet. These two buttons can be configured by the user to
perform a variety of operations. The initial settings of
these buttons may vary,so the user should verify the initial
settings of the buttons before they are used (see section

2.2 "Buttons Configuration Options"). Pushing both user­defined buttons at the same time invokes the touch screen
calibration application. See section 1.5.1 "Touch Screen
Calibration" for details on this application. If the applica­tion configured for a particular button is running when the
buttonis pressed, the applicationis aborted. This includes
pressing both buttons to abort the touch screen calibration
application.

2.2 BUTTONS CONFIGURATION OPTIONS

This link allows the user to configure the operation of the
tablet's buttons. Figure 6 identifies the buttons. Figure 7
shows the button configuration screen and examples of
how buttonscan be configured. Next to each button identi­fier is a field defining the button's operation.

To change the function of a button, replace the current
operation with a new operation. The operations take the
form of:

<action>[<type>]

<action> - defines the type of operation the button pro­vides. The values are: CMD, KEY, MAC. When a button
with the action of CMD is pressed, a command is exe­cuted. The KEY action is used to define the button as a
particular key from the keyboard. The MAC action invokes
amacro.

BUT1

BUT6

BUT3

BUT5

BUT2

FIGURE 6. Button Identifier Diagram

BUT4

<type> - is dependent on the action defined. For “CMD”
actions, the type is the executable command string. For
“KEY” actions, the type is either “UP”, “DN”, “LF”, or “RT”
and refers to the Up, Down, Left and Right arrow keys on
the keyboard. For “MAC” actions, the type is NXT. NXT
cycles between all active windows.

3.0 Favorite Sites Window

Selecting the Favorites icon brings up the Favor ite Sites
window. From here, the user navigates to favorite web
pages. The WebPAD system can s tore up to 512 site loca­tions.

The Favorite Sites window is split into three s ections. The
top section contains a list of the web sites that have been
saved. Below that is a section that displays the URL

Geode™ SP3GX01

address for the selected site in the favorites list. Along the
bottom of the window is a series of buttons used to navi­gate amongst and manage the l ist of sites. The functions
provided by these buttonsare:

• Bringing up the designated home page

• Adding a page to the list

• Deleting a page from the list

FIGURE 9. Favorite Sites Window

• Sorting the list

• Navigating to a selectedlink
Figure 9 shows the Favorite Sites Window.
The browser can be sent to the designated home page at

any time by selecting the Home button in the Favorite
Sites window. This action does not effect the pages you
have already visited in this session, so the Back button
still sends the browser to the previously visited page.

Sites are added to the list using one of two methods. The
first method uses the icon supplied in the border of the
browser. Touching this icon immediately sends the site
currently shown in the browser window to the list. The
second method is to open the desired site to be saved,
bring up the Favorite Sites window and touch the “Add”
button.

To delete a page from the list of favorites, highlight the
site, then touch the “Delete” button. If a site was acci­dently deleted, the only way to replace it on the list is by
going to the site and selecting the icon in the border of the
browser, or selecting the “Add” button in the Favorite Sites
window while the site is open.

Sites are listed in the order they are added. As the list
grows, use the Sort button to alphabetize the entries. New
sites appear at the bottom of the list.

4.0 Setup and Troub leshooting

This section explains how to setup and troubleshoot a
WebPAD system. The system consists of the tablet, base
station, and cradle.

4.1 SETTING UP A WEBPAD 1.5 SYSTEM

The WebPAD 1.5 System that you receive may come with
one of two types of base stations: A DECT-based or an

802.11-based Access Point. Please refer only to the sec­tion for the type of base station accompanyingyour partic­ular WebPAD 1.5 system.

4.1.1 Dect-based Base Station

4.1.1.1 Setup Guidelines

The following is the sequence used for setting up a Web­PAD system.

1. Connect the power cord and phone cable(s) to the
base station. The phone line and power jack connec­tors are located at the rear side of the base station.
ThelinetothewallgoesinthetopdualRJ-11
connector, and the line to the phone set (optional)
goes directly below it. The single RJ-11 connector is
not used at this time. The power cord plugs into the
power jack at the bottom of the unit.

To navigate to a stored web site, select the appropriate
link in the list and touch the “Go To” button or double click
directly on the link. This page will be placed on the stack
immediately after the page currently being viewed. Pages
before the current page will be lost.

2. Power on the base station, then the tablet. If this is
the first time the tablet has been used with this base
station, they must be registered with each other (see
section 4.1.1.2 "WebPAD/Base Station Registration").
Otherwise, the tablet establishes a link to the previ­ously registered base station. The system is now
ready for use. Upon starting, the browser loads its
home page. When the base station receives the
request for the web page,it establishesits connection
to the internet.

Warning: The base station must be installed in a

location which will ensure that personnel are at
least 20 cm or more from the device.

If the 20 cm separation is not maintained, the device
may exceed the FCC RF exposure limits and use
should be avoided.

4.1.1.2 WebPAD/Base Station Registration

Before a base station and tablet can communicate with
each other, they must be registered together. The regis­tration process is a s imple one.

1. Power up the base station and the tablet.

2. Invoke the DECT Monitor utility using the QNX menu
button in the lower left corner of the screen.

3. In the Dect Monitor window, select the Utilities menu,
followed by the “Scan Base Station” entry. The tablet
scans for base stations to be used. A window
appears listing all of the base stations found.

4. Select the box next to the base station to be used.

5. Press the Registration button located on the front of
the base station.

Note: Step 8 (below) must be completed within one

minute of pressing the Registration button (step

5). If step 8 is not been completed with one
minute of step 5, repeat steps 4 through 8.

6. In the “Scan Base Station” window, touch the Select
button. Another window will appear, listing the capa­bilities of the base station.

7. Once all the capabilities of the base station have
been listed, enter the PIN code in the PIN Code text
box.

8. Press the Register button in the window of the tablet.

Note: This step must be completed within one minuteof

step 5 (above). If step 8 is not completed within
one minute of step 5, repeat steps 4 through 8.

This initiates the registration process. When completed,
the tablet and base station will have established a com­munication link between them.

4.1.1.3 Using The System

The Internet Dial-up Connector utility is now ready to con­nect to the new ISP.

4.1.1.5 Login Scripts

Login scripts search for particular text strings in a certain
order. When the dialer finds the string it is looking for, it
replies with the designated text string. These scripts are
created and edited in the Internet Dial-up Connector util­ity, in the ISP Setup window (see 4.1.1.4 "Adding a New
Dial-up Account"), on a WebPAD 1.5 system that contains
a DECT base station. In the ISP setup window, select
either an existing script or enter a new script name, then
touch the “Edit Script...” button to open the Script Editor
window.

Each step shown in the window is processed in sequence,
starting at the top. Each line is composed of three parts:
what to wait for, what to reply with, and what status is to
be posted. On the right side of the window are buttons to
insert steps or modify/remove the currently selected line.
Three boxes at the bottom of the window are used to edit
the settings of the currently selected line.

To modify a line, select it. The contents of the line are then
shown in the boxes at the bottom. Modify any or all of the
selected line. After completing the modifications, touch
the “Modify” button to save the changes.

Note: The keyboard containsa “www.”and a “.com” but-

ton to simplify the typing process).

This last step reboots the access point. When the access
point completes the reboot process, the new dial-up
account will be established.

4.2 TROUBLESHOOTING

4.2.1 Tablet Does Not Power On

If the tablet will not power on when the power button is
pressed, the batteries may not have enough power to
operate the device. Plug the AC adapter into the tablet to
charge the batteries. The tablet can be used during the
charging process.

If the tablet still does not boot and the green LED flashes
for 5 seconds, the tablet has overheated. Allow the tablet
to cool down and try again.

4.2.2 RF Link Is Down

If the RF Link icon indicates the link is down, the radio in
the tablet is not able to communicate with the radio in the
base station. This problemcan have several causes:

1. First, make sure the base station has completely
booted. If it has not, wait for it to complete booting
and check to see if the icon has changed to indicate
the RF link is up.

5. Press “Enter.” The desired web site will appear.
The browser is also capable of moving between previ-

ously loaded pages, reloading pages and stopping the
loading of a page (via the icon in the top border of the
browser). To follow links between pages, simply touch the
link and the browser will load and display that page.

4.1.2.3 Adding a New Dial-Up Account

Add a new dial-up account to the Access Point via the
web browser on the tablet, as follows.

1. Go to the configuration page Radio->Configure
Access Point. See section 2.3 "Radio Configuration
Options".

2. Touch the “Setup” link in the border on the left side of
the page. This provides the user with a summary of
the settings for the access point.

3. Before going any further, the access point requires
the user to enter a password. Enter the password. If
the password shows as a series of asterisks, the
passwordis remembered by the system and need not
be re-entered.

4. In the border on the left side of the page is a “Basic
Setup” section. Touch on the Internet Access link in
this section.

5. Enter “ISP Phone Number,” “ISP Login Name” and
“ISP Password.”

6. Touch the “Enter” button directly beneath where the
information has been entered.

7. Touch the “Save” button to save all changes.

2. If the base station has completely booted but the RF
link icon indicates the link is still down, the radio in the
tablet may not be receiving a strong enough signal
from the base station. Either the distance between
the tablet and base station may be too great or inter­ference could be a factor. Try moving the tablet closer
to the base station. If the icon has changed to indi­cate the RF link is up, operate the tablet closer to the
base station.

Refer to the following only if using a DECT-based base
station:

3. If the base station is DECT-based, run through the
registration process. If the tablet and base station are
not registered with each other, the system will not
function properly. If registered, but still not working,
please contact the service representative for assis­tance.

Refer to the following only if using an Access Point base
station:

3. If the radio in the tablet is still not communicatingwith
the radio in the base station, check the system IDs of
the radios in both the base station and the tablet.
These IDs must match. If they do not match, change
them to match. The default system ID is “Nokia
WLAN”.

4. T o check the system ID on the tablet, refer to section

2.3 "Radio ConfigurationOptions".

5. To check the system ID on the access point base
station:

a. Disconnect the modem. Connect a null modem

cable to the back of the base station.

www.national.com 14 (Confidential) Revision 1.2

b. Connect the other end of the null modem cable to

a PC and bring up a terminal emulation program
on the PC.

c. Set the serial port on the PC to 9600 baud, 8 data

bits, no parity, and 1 stop bit.

d. If “Password:” i s not displayed, press the “Enter”

key until it appears. Enter the password. The
defaultpassword is default.

e. At the prompt, type “config”. In the information

displayed on the screen, look for the entry
Network Name. This value must m atch the
system ID on the tablet.

If none of the above recommendations solves the prob­lem, call the service representative for fur ther assistance.

4.2.3 Error Received When Accessing Web Site

If the link between the tablet and base station is up, prob­lems may still occur when trying to access a web site.
Certain problems can be resolved by the user. Others will
require assistance from another source, such as the Inter­net Service Provider (ISP).

1. Check the network settings on the tablet. Make sure
the proper proxy port address is set up for the proxy
server selected (see section 2.1.4 "Browser>Net-

work").

2. Verify that the ISP’s phone number, user name and
password have been correctly entered (see section

4.1.1.4 "Adding a New Dial-up Account" for DECT­basedbasestationand4.1.2.3"AddingaNewDial­Up Account" for the access point base station).

3. Verify the base station has established a connection
to the ISP. With an access point base station, bring
up the access point’s configuration screen by going to
the web page http://manage.ap. If an animated GIF is
active between the representation of the access point
and the world icon, the connection is up and active. If
not, touch the “Connect” button to initiate the connec­tion sequence. If you have problems connecting, go
to the “Status” web page. Select the “Modem” link,
then select “View PPP Log”. This log lists all the
activity taking place over the modem. This log will
help when discussing the connection problem with
the ISP.

If a problem still exists, contact your service representa­tive for assistance.

4.3 USING TWO OR MORE TABLETS FROM THE

SAME BASE STATION

The ability to support more than one tablet on a base sta­tion depends on the type of base station supplied with the
device. The 802.11-based access point base station is
already set up to handle this topology, without any extra
configuration.

The DECT-based base station, however, does not support
multiple tablets. These base stations only support a one­to-one topology.

Geode™ SP3GX01

4.4 REALAUDIO/REALVIDEO CONFIGURATION

The WebPAD system contains a RealPlayer application.
To configure the RealPlayer on the tablet, follow these
steps:

1. On the tablet, bring up a terminal window. Touch the
Virtual Keyboard task boxto bring up the keyboard.

2. At the “#” prompt, enter the command:

3. Once the player window appears, select the “View”
menu.

4. Select the “Preferences” submenu. A new window
labeled “Preferences” will be displayed. This window
has several tabs; s elect the “Connection” tab. Verify
that the bandwidth is correct for the base station’s
Internet connection.

5. Select the “Proxy” tab. This form notifies the player of
theproxyserver.If“UseProxy”isselected(thebox
next to it is colored), then deselect it by touching it.

6. Touch “OK” to save the changes.

Once the RealPlayer on the tablet has been set up, log
onto the network to test it. If the player is not working, call
the service representative for assistance.

5.0 Upgrading Tablet Software

As new functionality is developed and modifications are
made, the software residing in the tablet will need to be
upgraded.The tablet’sbrowser is the main source used to
access and implement upgrades. To implement an
upgrade, point the browser at the server containing the
latest software. Once the image has been selected, the
browser will download the image to the tablet. Once the
download is completed, the image is unpacked and
placed into the current directory structure. The tablet then
automatically reboots i nto the new upgraded system. If,
after the upgrade, the system is not working properly, refer
to section 4.0 "Setup and Troubleshooting" or contact the
service representativefor further assistance.

5.1 UPGRADE PROCESS

An upgrade is performed off of a web server. This web
server can be one operated by the user or the National
Semiconductor WebPAD site. To perform an upgrade:

1. Bring up the browser on the WebPAD tablet, and go
to the site which contains a link to the software
update file.

2. Locate the link to the latest version of the software
and touch it to start the download process.

3. When a question appears in the dialog box, asking if
the update should be performed, touch the “Yes”
button to install the upgrade.

If the user has modified any of the settings from the

default values, these settings will have to be reset to
the desired function upon completion of the upgrade.
