Chapter 1 - Introduction
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 easy-
to-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.
The WiJET is an 802.11b®compliant product designed specifically for wirelessly
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.

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.).

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.

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.

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.

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.

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

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.

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.

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.

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.

19
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
