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:” is not displayed, press the “Enter”
key until it appears. Enter the password. The
default password is default.
e. At the prompt, type in “config”. In the information
displayed on the screen, look for the entry
Network Name. This value should match the
system ID on the tablet.
If none of the above recommendations solves the prob-
lem, call the service representative for further assistance.
4.2.3
Received an error when trying to bring up a
web site
If the link between the tablet and base station is up, prob-
lems 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 from 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>Network”)
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 DECT-
based base station and Section 4.1.2.3 “Adding a
New Dial-Up 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 connec-
tion 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 representa-
tive 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 sta-
tion 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 one-
to-one topology.
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 box to bring up the keyboard.
2.
At the “#” prompt, enter the command:
rvplayer &
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; select 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
the proxy server. If “Use Proxy” is selected (the box
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.

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’s browser 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 into 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 representative for further assistance.
The tablet image can either be upgraded locally or
remotely. The local upgrade can only be done if the Web-
PAD system being used has a laptop base station or
another PC has been set up to act like a laptop base sta-
tion. Without a separate PC, WebPAD systems shipped
with the access point base station will not be able to per-
form a local upgrade. All WebPAD systems are capable of
performing the remote upgrade.
5.1
REMOTE UPGRADES
A remote upgrade is performed off of a web server, not a
laptop base station. This web server could be one oper-
ated by the user or the National Semiconductor™ Web-
PAD software update site. To perform a remote upgrade:
