Chapter 1 - Introduction
The WiJET is an 802.11b
connecting projectors and monitors to computers. It connects to the existing VGA
connector of the projector/monitor and offers 802.11b® connectivity up to 11Mbps.
The advantages of the WiJET become obvious in any conference room where the ideal
location of the projector or display screen makes it difficult for a laptop or desktop to
connect to it while allowing the speaker to maintain audience interest. All too frequently,
projectors placed in the middle of the room force the speaker to present from the middle
of the room, because of the VGA cable that exists between the projector and the
presenter’s laptop.
The WiJET solves this problem by allowing any laptop or desktop with an 802.11b WiFi
adaptor to give the presentation from anywhere in the conference room that the presenter
desires. Wherever the presenter feels would garner the most amount of interest from the
audience. Truly freedom from wires allows for more flexibility in meetings.
Another application of the WiJET is in a situation where multiple presenters must give
presentations in rapid succession. The WiJET allows for fast handover of the projector or
monitor without the hassle of removing and reattaching the VGA cable. Using the easyto-use Presentation Session Manager, the presenters can effortlessly connect to the
WiJET, give a presentation, and disconnect from the WiJET to allow another user to
connect to it without touching a single cable. Contrast this to physically disconnecting
and reconnecting the VGA cable as well as configuring the laptop to output to the
laptop’s VGA connector and it is easy to see how the WiJET can make multiple people
giving presentations effortless.
A third application that showcases the advantages of the WiJET is where there are
multiple conference rooms with multiple projectors. A WiJET in every conference room
will substantially save setup time when the presenter comes into the room. The presenter
only simply selects the WiJET number displayed on the projector/monitor screen and he
is instantly connected to the projector and able to start his presentation. This removes a
lot of setup time associated with presenters moving from room to room to give their
presentations, ultimately saving IT costs.
In summary, the WiJET is a tool that will change how people come to view conferences
and meeting rooms. Instead of a static meeting place, the conference rooms can now
become a dynamic meeting place where new thoughts and ideas are exchanged and
created.

Chapter 3 – Using the WiJET
Using the WiJET in a Meeting
The most important benefit of replacing a VGA cable with a wireless connection in using
a presentation projector or monitor is to enable fast handover of the projector or monitor
control among multiple meeting participants. The WiJET Presentation Session Manager
(PSM) is a simple user interface allowing quick rotation of presentation among multiple
presenters. The following simple steps sketch out how a successful WiJET Wireless
Presentation Meeting unfolds:
1. Copies of the installation CD are kept with the WiJET in the meeting room. The
meeting host, before the presentations start, identifies the meeting participants
who do not yet have the WiJET Presentation Session Manger installed on their
computers and hands them the installation CD’s. The installation is automatic and
does not require rebooting the computer.
2. The meeting host asks all meeting participants to establish a wireless connection
to the WiJET before the meeting starts. Most participants can accomplish this by
clicking just one button (“Select”, see below). This wireless connection is kept
alive throughout the meeting even if only one presenter can use the projector or
monitor at a given time. Confirming wireless connections before the meeting
starts assures a smooth presentation session.
3. At any given time, by clicking just one button (“Connect”, see below) in the PSM,
one designated presenter can start the presentation and exclude other presenters
from using the projector/monitor.
4. At the click of one button (“Stop”, see below) in the PSM, the incumbent
presenter yields the floor (the projector/monitor) to another presenter while still
maintaining a live wireless link to the WiJET.
5. At the click of one button (“Connect, see below) in the PSM, a waiting presenter,
owing to the already established wireless link, can instantaneously take over the
projector/monitor.
The normal meeting etiquettes have to be followed to determine how the control of the
projector/monitor should be rotated among presenters. The WiJET and its PSM make the
rotation easy and quick and thereby make the meeting dynamic.
Configuring your Computer to control the WiJET
The WiJET is designed to be in the “Ad-Hoc” mode instead of the “Infrastructure” mode.
This means you have to configure your Wireless card to connect to the WiJET, but do not
have to change any of your network settings (IP address, etc.).
9
Page 10
The steps below will detail how to connect to the WiJET either using the automatic
wireless device configuration (only for WiFi cards with a driver supporting MAC I/O), or
to configure your WiFi device manually.
WiJET Presentation Session Manager
When the WiJET is first turned on, it will undergo a boot up sequence that results in a
banner screen with two important pieces of information. On the top left hand corner will
be a name like WiJET0001 or WiJET0005. This is the SSID of the WiJET and will be
the SSID used to configure your network card to control the WiJET. The number on the
right is the channel number the WiJET is on.
You have to start the WiJET Presentation Session Manager (PSM) to control the WiJET.
The WiJET PSM program is located under the Programs Folder in the Windows Start
menu, WiJET Utility as shown in Figure 1.
Figure 1 Location of WiJET program
Once the program icon is selected, the WiJET PSM will start. The PSM does not open a
window, but rather starts out as a tray icon as shown in Figure 2.
Figure 2 PSM Tray Icons
To activate the main window of the PSM, either double click on the PSM Tray Icon or
right click on the icon and select “Open” as shown in Figure 3.
10
Page 11
Figure 3 Right Clicking the PSM icon will give you a submenu
A window should appear like the window in Figure 4. There are 4 action buttons in the
PSM: “Select”, “Connect”, “Stop”, and “Cancel”. Clicking “Cancel” simply makes the
PSM vanish from your Desktop. The other 3 action buttons are described below.
Figure 4 The WiJET Presentation Session Manager
Configuring your Wireless Adaptor to Connect to the WiJET
PLEASE NOTE: For those users whose computer’s wireless adapter card (PCMCIA,
mini-PCI or external USB device) uses a driver with MAC I/O control, the WiJET
Presentation Session Manager automatically configures the card to connect to WiJET.
For users with a wireless card that has a legacy driver without the MAC I/O control or
with an external, driver-less Ethernet Station radio, such as OTC’s ACR-201, manual
configuration of your card is necessary. The WiJET Presentation Session Manager
informs you whether your card can be configured automatically or not. Please read the
details given below.
In general, the steps to configure your Wireless Adaptor should be as follows.
11
Page 12
1) Use the automatic configuration utility unless your operating system is Windows
98
2) If the automatic configuration succeeds, you are ready to use the WiJET!
3) If the automatic configuration fails, manually configure your wireless adaptor.
For Windows 98 users, please see the section “Manually Configuring the Wireless
Adaptor”. For XP users, please see the section “Configuring the Wireless Adaptor for
Windows XP”.
Automatically Configuring the Wireless Adaptor
To configure your Wireless Adaptor automatically to use the WiJET, click on the Select
button. A separate window should pop up as in Figure 5.
Figure 5 WiJET Select Window
Select your WiJET from the dropdown list. Note that you can only see two WiJET
numbers at one time and there are a total of 9 possible WiJET SSID numbers. To see the
other WiJET SSID numbers, simply click the up and down arrows at the side of the drop
down box like in Figure 6.
12
Page 13
Figure 6 Using the up and Down arrows on the Drop Down window
The WiJET number to select appears on the upper left corner of the WiJET-ready banner
page on the projector/monitor screen in your meeting room. It is important that you make
this proper determination as there may be other WiJETs operating in the vicinity.
When you have selected your WiJET number, simply click OK. You will see a
“Configuring Device” message show up on the WiJET Select window. A few moments
later, you should be seeing a window pop up telling you that configuration has succeeded
as in Figure 7.
Figure 7 Setup completed
Click the “OK” button and it should return you to the WiJET PSM window.
If, after you have made the WiJET selection and have seen the “Configuring Device”
message in the “WiJET Select” Window, the “Automatic setup not available” window
(Figure 8 below) pops up, then your computer’s wireless card either is not properly
installed or it uses a legacy driver that does not support MAC I/O. You will need to
manually configure your wireless card with its utility program. The steps are as follows.
13
Page 14
Figure 8 Automatic setup not available
Manually Configuring the Wireless Adaptor
Looking at the banner page on the projector/monitor screen in your meeting room,
determine the SSID that the WiJET is currently set on. The SSID that the WiJET is on is
displayed on the top left hand corner of the screen and is in the format of WiJET000x,
where x is a number from 1 – 9. The channel number the WiJET is on is displayed on the
top right hand corner of the screen and is a number from 1 – 11 for the US or 1 – 13 for
Europe.
Open the Configuration Utility program (which may be called a different name for your
wireless card) for your wireless card, and do the following:
1. Change the “Network type” to “Ad Hoc” or “Peer-to-Peer”. It should not be in
the “Infrastructure” mode.
2. Change the “SSID” of the wireless card to that of the WiJET, that appears on the
projector/monitor screen.
3. Optionally, change the “Channel” to that of the WiJET, the number between 1
and 11 (or 1 and 13 for Europe) that appears on the upper right corner of the
WiJET-Ready-Image.
4. Observe the indications on the utility program of your wireless card to assure that
it is connected to the WiJET.
Configuring the Wireless Adaptor for Windows XP
To configure your Wireless Adaptor for Windows XP, you must first know if your
Wireless Adaptor is natively supported under Windows XP. The easiest way to know
this is to see if an icon is in your system tray as in Figure 9.
Figure 9 Network Adaptor with native support under Windows XP
14
Page 15
If your system tray looks like the figure shown in Figure 9, your wireless card is natively
supported under Windows XP and you should read the rest of this section as it will
instruct you in how to connect your wireless adaptor to the WiJET under Windows XP.
If you do not have the addition Wireless Network Connection icon in your system tray,
you should see if you have some sort of Wireless configuration utility in your system tray
instead, as in Figure 10.
Figure 10 Network Adaptor utility provided by 3rd party; No native support in XP.
If your system tray looks like the figure shown in Figure 10, your wireless card is not
natively supported by Windows XP and you should go to the section above labeled
“Manually Configuring the Wireless Adaptor”.
To configure the natively supported network adaptor, double-click the wireless network
connection icon in the system tray. You should get a figure much like Figure 11.
Figure 11 Wireless Network Connection Status Window
Click the Properties button. A new window much like Figure 12 should appear.
15
Page 16
Figure 12 Network Properties for Wireless Adaptors
Click on the “Wireless Networks” tab and you should see a figure like Figure 13.
Figure 13 Wireless Networks tab.
16
Page 17
Here you will find the various networks that your wireless card has been able to detect.
To allow for a connection to the WiJET, you must click the “Advanced” button. A figure
like Figure 14 should appear.
Figure 14 Advanced Network Settings Window
Set the configuration to be “Computer-to-computer (ad hoc) networks only” and click the
“Close” button. Take note of the Preferred Networks area. You should see only ad hoc
networks now as in Figure 15.
Figure 15 Preferred networks changed to Ad Hoc networks only
If there is more than one ad hoc network, you must use the “Move up” and “Move down”
buttons to move the WiJET you wish to have connected to the top. When you are done,
press the “OK” button. At that time you should be back to the desktop and your system
tray should display an image much like Figure 16.
Figure 16 Connected to WiJET
Congratulations, you have connected your XP machine to the WiJET. You are now
ready to start your WiJET presentation session.
17
Page 18
Start or Resume Your WiJET Presentation Session
Once you have successfully configured the wireless card to connect to the WiJET, either
manually or automatically, and when it is your turn to make a presentation, click
“Connect” and you should find yourself connected to the WiJET. There will be no
confirmation window alerting you that your connection is live, and your projector or
monitor should now display your Desktop. If you have a graphic background, you will
notice that it has been replaced by a generic blank gray background.
Various abnormal conditions, such as RF interference and TCP/IP time-out, however rare
in occurrence, can cause the communication between the WiJET and the PSM to be
interrupted. The WiJET continuously monitors a pre-defined exchange between the
WiJET and a presenter’s computer (even when there is no display updates) in order to
detect an interruption of the link. Certain abnormal conditions that cause interruption of
the link may be localized on the current presenter’s computer and/or its wireless card. To
prevent the WiJET from being locked up by the current presenter, the WiJET returns
itself to an “available for connection” state and alerts the users of a link interruption by
putting the WiJET-ready banner page back on the projector/monitor screen. When this
“alert” banner page unexpectedly re-appears in the middle of a presentation, the presenter
can click the “Connect” button to try to resume a WiJET Presentation Session. If the
abnormal condition is temporary, the presentation session should resume instantaneously.
If the abnormal condition persists but is localized on the current presenter’s computer
and/or its wireless card, another presenter can still make use of the projector/monitor by
clicking the “Connect” button on his/her PSM.
Stop Your WiJET Presentation Session
If at any time you wish to disconnect your computer from the WiJET, simply bring up the
WiJET PSM and click on the “Stop” button. Clicking the “Stop” button does not
terminate the wireless connection between your computer and the WiJET. It simply
yields the control of the WiJET so that the next presenter can have control of the WiJET
and make a presentation. The wireless connection to the WiJET stays live after clicking
the “Stop” button so a presenter can quickly get back to another turn of presentation.
Exit the WiJET Presentation Session Manager
Either clicking the “Close” button in the PSM, or right-click the WiJET Tray Icon and
then click “Exit” will terminate the WiJET User Software. The Tray Icon will disappear
from your Windows start menu.
Upon termination, the WiJET software restores your wireless card to its original settings
if the card has been automatically configured.

Chapter 4 – Using the Web Based Utility
Introducing the Web Based Utility
Along with the software based utility that is available on the install CD, the WiJET also
has a Web Based Utility that allows you to configure other aspects of the WiJET. This
includes the initial banner page that you see when the WiJET is first powered.
Accessing the Web Based Utility
There are two ways of accessing the Web Based Utility. One way is to install the WiJET
Administration Tool as described in Chapter 2 – Installation for the WiJET
Administration Tool. The other way is to configure your radio manually, and then
manually opening your web browser to access the web based utility.
Configuring Your PCMCIA Adaptor Automatically
To configure your PCMCIA Adaptor automatically to access the Web Based Utility,
click on “Start”, “Program Files”, and then “WiJET Utility”. You should see a screen like
Figure 17 below.
Figure 17 WiJET Utility
If you click on “Administration”, a window like Figure 18 will appear.
Figure 18 WiJET select Screen for Administration Tool
19
Page 20
Select from the WiJET list the WiJET number and click “OK”. There should be a
message that states “Configuring your Wireless Card” before a “Setup Completed”
window appears.
Click OK on the Setup Completed window and click on connect. A web browser should
appear and you should be prompted with a User Name and Password.
Configuring Your WiFi Adaptor Manually
To access the Web Based Utility on the WiJET, you must setup your WiFi card as
instructed in Chapter 3 - Configuring your computer to Control the WiJET. Once you
have setup your Wireless Card to be able to control the WiJET, you must connect to the
WiJET using the PSM.
After you have connected your computer to the WiJET via the PSM, open a web browse
and enter your computer’s current IP address plus one; For example, if your computer’s
current IP address is 192.168.11.224, try entering 192.168.11.225.
When you successfully reach the web site, you should reach the following web page.
Figure 19 Logon Screen
The User Name is admin and the password is public. Once you have pushed the OK
button you should see the following web page as in Figure 20
20
Page 21
Figure 20 WiJET Web Utility Screen
There are several details worthy of notice on this webpage and it shall be explained
below in greater detail.
WiJET Firmware Version
This is the current WiJET firmware version. It is important when you are calling or
emailing tech support to know which WiJET firmware version you have.
Configuration
When you click on the Configuration hyperlink, you should see the following screen as in
Figure 21
Figure 21 Configuration screen
21
Page 22
This is the configuration screen where you set the security for the WiJET. The
description of each feature is as detailed below.
WEP enabled:
This check box allows users to enable or disable WEP feature. The WiJET
currently supports only the default (shared) WEP key scheme defined in the 802.11
standard, not the mapped key scheme. A set of four keys needs to be created in the
default-key scheme.
WEP key length: The 64-bit encryption is currently the 802.11 standard. The 128-bit
encryption is supported by equipment from a limited number of vendors. Note that the
“user-controlled” portion of the 64-bit encryption is just 40 bits (10 Hex digits) and that
for the 128-bit encryption is just 104 bits (26 Hex digits)—3-bytes of the encryption key
are internal to the encryption algorithm.
Authentication Type:
When the “Open system” option is chosen, no encryption is applied
to the exchanged packets between this Station radio and another radio. Communication
with another radio (a station or an AP), however, can be successful only if the other radio
also is set up to communicate in the “Open system” mode. When the “Shared key” option
is chosen, the “Encryption” page of the Utility program must be properly filled out. See
“Encryption” page for details.
Transmission key selection: One of the four default keys needs to be selected for
transmitting data frames. The radio can de-encrypt received data encrypted in any one of
the four default keys, but it uses only one of the default keys for transmitting its data.
Channel Selection Mode: Automatic or Manual. This is to set the WiJET to be in
automatic channel selection mode (default) or manual. The recommendation is to leave
the WiJET on automatic channel selection mode unless you have very crowded
communications and are sure only certain channels are open.
Channel:
Available only if you select the Channel Selection Mode checkbox. You can
select a channel from one to eleven.
Reset to Factory Default: This will set the WiJET back to its factory default settings for
the configuration page.
22
Page 23
Administration
When you click on the Administration hyperlink, you will see the following page as on
Figure 22.
Figure 22 Administration Screen page
User Name: This is where you can change the default user name of “Admin” into
something else you desire. The character limit is 16 characters for this field.
Enter New Password: This allows you to change the password of the WiJET. The
default is “public”, but you can change it to anything you like. Character limits on the
password is also 16 characters.
Confirm New Password: To confirm the password that you entered in the above field.
Reboot WiJET:
This will reboot the WiJET. Note that it will not change the User name
or password if you did not click Apply beforehand.

Firmware and Banner Page Upload
When you click on the Firmware and Banner Page hyperlink, you should see the
following page appear.
Figure 23 Firmware and Banner Page Upload
Upload Options: To select which functionality you wish to perform on the WiJET,
whether it is a firmware upload or a Banner page upload. Select which of the two
options you wish to select and check the appropriate selection circle.
File path/name: If you click the browse button to the right of the field, you will get a file
selection box. For Firmware file, you will want to get the file with the extension of
.tar.gz. For Banner page file, you will want to get a file with the extension of .jpg. For
the best picture on the WiJET banner screen, the picture file should be of 1024 x 768
resolution. The maximum .jpg size is 2 megabytes or 2048 bytes. When uploading the
firmware or banner page, do NOT power off or disconnect the WiJET. Doing so may
damage the equipment.

Connect Status shows up but the WiJET only displays the banner screen
If you see this screen (Figure 24) for an extended period of time, with the connect bar
increasing, then you will most likely not be able to connect to the WiJET.
Figure 24 Unable to Connect to the WiJET symptoms
Eventually, you should see the screen as in Figure 25
Figure 25 Target Not Found
There are several causes for this.
1) The computer’s WiFi adaptor’s SSID is not set up to be the same as the WiJET’s.
2) The computer’s WiFi Adaptor is not set to Ad-Hoc or Peer-to-Peer mode.
3) The WiJET is somehow not receiving the wireless signal, power-cycle the
WiJET.

4) With certain brands of PCMCIA 802.11b WiFi cards, it might take a bit longer to
link up with the WiJET than with other brands of PCMCIA cards. The reason for
this is that the drivers and features set of each brand might cause the link up time
between the WiJET and the computer to take longer. Simply click “Retry” as you
see on Figure 15 and let the Connect Status screen show up again. If the “Target
Not Found” window appears again, there probably is no link established between
the WiJET and the computer.
The WiJET banner page unexpectedly re-appears in the middle of a presentation
This signals that the WiJET has detected a link-loss lasted more than 8 seconds. Since the
WiJET is designed to support one presentation at a time, the WiJET returns itself to the
initial state (where displaying the banner page is a part) of being “available for
connection” in order to prevent the WiJET from being locked up with one possibly
malfunctioning user computer.
When this condition occurs, follow the steps below:
1. The current presenter should click “Connect” to try to resume the presentation. If
the presentation is successfully resumed, the abnormal condition is just temporary
and no further action is required.
2. If the current presenter failed to resume presentation by clicking “Connect”,
another presenter should try to “Connect”. If this new presenter can successfully
start a presentation, the problem was localized on the previous presenter’s
computer and/or its wireless card. Address that problem after the meeting.
3. If a second presenter also fails to “Connect” to the WiJET, a persistent abnormal
condition has to be identified. Follow other trouble-shooting tips in this chapter to
identify the persistent abnormal condition.
Radio Interference
You may be able to eliminate RF interference by trying the following:
• Find the “channel” used by the source of the interference and coordinate your
network and the interference source to be on channels that are at least 20MHz, but
preferably 30MHz, apart.
• Reseat the WiJET to a location where the interference is minimized; in general,
increase the distance between the wireless computers and the device causing radio
interference.
• Avoid using 2.4GHz cordless phone in the vicinity of the radio
• Keep the computer with the WiJET away from the microwave oven and large
metal objects.
• Consult the dealer or an experienced radio technician for help.
