Chapter 1: INTRODUCTION

The WiJET.G is an IEEE 802.11g 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 802.11g connectivity up to 54 Mbps.

The advantages of the WiJET.G 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.G solves this problem by allowing any laptop or desktop with an 802.11g
Wi-Fi adapter 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.G is in a situation where multiple presenters must
give presentations in rapid succession. The WiJET.G 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.G, give a presentation, and disconnect from the WiJET.G to allow
another user to connect to it without touching a single cable.

A third application that showcases the advantages of the WiJET.G is where there are
multiple conference rooms with multiple projectors. A WiJET.G in every conference
room will substantially save setup time when the presenter comes into the room. The
presenter only simply selects the WiJET.G 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.G 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 2: WiJET.G SYSTEM INSTALLATION

2.1 Safety Statements

Use only the power adapter provided with this product or the manufacturer's authorized
replacement power supply.

Connect the power adapter to a properly grounded electrical outlet that is near the
product and easily accessible.

Refer service or repairs, other than those described in the user documentation, to a
professional service person.

2.2 Hardware Installation

2.2.1 Power

Power is supplied to the WiJET.G via a 1.7 amps 5 volt DC power adapter.

Warning: use only the power supply adapter provided with this product or the

manufacturer’s authorized replacement power supply.

2.2.2 VGA Connection

This is a standard 15 pin female VGA connector where you will connect the WiJET.G

to either a monitor or a projector via a straight-thru monitor cable (either purchased
separately or with the one that comes with the projector or mon

itor).

2.2.3 Status LED’s

There are two status LED’s on the WiJET.G. From the front of the unit, the LED on the
left is the power indicator while the LED on the right is the link status and video out
indicator. During boot-up, the link status LED will initially remain unlit. When the link
LED blinks red, it means the WiJET.G is ready for connection to a PC. Upon
connection from a computer, the LED will turn solid green. Upon disconnection, the
LED will revert to blinking red again.

2.2.4 Hardware Reset Button

The hardware-reset button is located at the back of the WiJET.G. It requires a bent
paper clip to access the hardware-reset button. The main function of the hardware­reset button is to reset the WiJET.G unit back to the factory default settings. However,
to perform the reset to factory default, the procedure below has to be followed.

1. Turn on or reboot the WiJET.G

2. During the boot-up screen, a message “Reset to factory default” timer starts
appears and the user will have approximately 10 seconds to do the following
step.

3. Push the hardware reset button on WiJET.G unit before the timer ends. The
WiJET.G shall automatically reboot itself.

WiJET.G Technical Manual

4. Observe that, during the next boot-up screen after above steps, a message of
Reset to Factory Default should appear next to the Timer message. It indicates
the operation is successful.

Note: The subsequent boot-up screen should not display the Reset to Factory

Default message unless being triggered using above procedure or having

corrupted data in the WiJET.G.

Caution: Please note that resetting the WiJET.G to its factory default means losing

all configurations and encryption information you may have set through the
web interface!

2.3 Software Installation

The following details the steps involved in installing the software needed to control the
WiJET.G.

2.3.1 System Requirements for User Software

To use the WiJET.G software, your computer must meet the following requirements.

• Wi-Fi or IEEE 802.11g enabled computer (either built-in or add-on NIC);

• (Optional) Wi-Fi or IEEE 802.11g Access Point

• Windows 98/NT4/ME/2000/XP; and

• Minimum equivalent processing power of Pentium 3 at 750 MHz and 64MB of

RAM.

2.3.2 Installation for the WiJET.G Software

This step is optional for those who simply want to run WiJET.G Presentation Session
Manager (PSM) without the administration capability. WiJET.G PSM can be executed
on CD-ROM without being installed to the local hard drive. To install the WiJET.G
utility software on your local hard drive, insert the Installation CD in your computer’s
CD-ROM drive. A selection window would automatically start and the user can choose
to run the PSM from CD-ROM or to install the PSM onto the local hard drive. If the
selection window does not automatically start, go to “My Computer”, double click on
the CD-ROM Drive where the Installation CD is located, and run “setup.exe”.

2.4 System Requirements for Web-based Administration Utility

WiJET.G has a Web-based Administration Utility for configuring the settings of the
WiJET.G. The web-based Administration utility can be accessed through the icon
located on the system tray once a session has been established. To use the WiJET.G
Web-based administration utility, the computer must meet the following requirements:

(1) A Web browser must be installed on the computer. The supported Web browsers
include Internet Explorer 5.0 and above. JavaScript for the browser must be enabled.

(2) IEEE 802.11b/g or Wi-Fi enabled computer (either built-in or add-on NIC).

WiJET.G Technical Manual

Chapter 3: USING WiJET.G

3.1 Using the WiJET.G in a Meeting

In addition to the obvious convenience with wireless connection, the most important
benefit of eliminating the VGA cable in using presentation projectors or monitors is to
enable fast handover of the projector or monitor control among multiple meeting
participants. The WiJET.G Presentation Session Manager (PSM) provides a simple
user interface allowing quick rotation of presentation among multiple presenters. The
following simple steps sketch out how a successful WiJET.G Wireless Presentation
Meeting unfolds:

1. Copies of the WiJET.G installation CD are kept with the WiJET.G in the meeting
room. The meeting host, before the presentations start, identifies the meeting
participants who do not yet have the WiJET.G Presentation Session Manger
installed on their computers and hands them the installation CDs. The
participants can either run PSM from the CDs or install the PSM onto their
system. 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.G before the meeting starts. Most participants can
accomplish this by clicking just one button. 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 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 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.G.

5. At the click of one button 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.G and its PSM
make the rotation easy and quick and thereby make the meeting dynamic.

3.2 Starting the WiJET.G

When the WiJET.G is first turned on, a boot up sequence will follow. After about
30 seconds, the WiJET.G will display the following graphic (Figure 3.1) with a few
informative messages.

WiJET.G Technical Manual

6

Figure 3.1 WiJET.G Banner Page

The messages will be displayed on the top of this image and consist of three lines. The
top line displays the SSID and the firmware version of the WiJET.G while the second
line reports the channel, radio mode, IP address, and MAC address. The last line
displays a list of detected channels that may cause interference.

An example of the messages is given below:

SSID=WiJET.G Version:1.1.b
Channel=11 Mode=Local Access Point IP=169.254.98.170 MAC=00:60:B3:25:4B:41
RF activities detected on other channels (none).

There are several variations to the message on the second line. The variations and
what they mean are as follows:

RF activities detected on other channels (none).

No other 802.11g channels detected in use other than the WiJET.G at all. Your
connection to the WiJET.G should be smooth and error free.

RF activities detected on other channels (8, 9).

WiJET.G Technical Manual

7

Existing 802.11b/g channels detected in use, but there is no interference. Your
connection to the WiJET.G should be smooth and error free.

RF activities detected on other channels (1, 5, 8, 11). WARNING:
Interference.

Existing channels detected and interference found. The WiJET.G is in a RF noisy
environment, you may have trouble connecting and maintaining connections to
the WiJET.G even if a connection can be made.

Note: WiJET.G updates this information whenever the banner page

appears. In a noisy environment, channel information might get
outdated quickly since the WiJET.G does not monitor channels
continuously.

Once you have turned the WiJET.G on and noted the above information, you can now
configure your computer to connect to the WiJET.G.

3.3 Configuring Computer to Control WiJET.G

Before starting the Presentation Session Manager, the network interface of the
computer must have a valid IP address. For computers running DHCP client mode
while DHCP server is unavailable, it may take a few moments for the computers to
obtain a system IP address. If users cannot obtain a valid IP address for the network
interface, please refer to any network administration references for how to assign IP
address to a network interface/connection.

NOTE: The computer’s network interface must have a valid IP address before PSM

starts.

3.4 Starting WiJET.G Presentation Session Manager

Start the WiJET.G Presentation Session Manager (PSM) to control the WiJET.G. There
are two ways to run the WiJET.G PSM. One is to run the WiJET.G PSM directly from
the utility CD while the other is to run a locally installed WiJET.G PSM from a hard­drive.

To run the PSM directly from the utility CD, insert the installation CD into CD-Drive and
click the “Run from CD” button in an auto-start window. If the auto-run window does not
show up automatically, open My Computer and explore on the CD-Drive where the
installation CD is inserted and execute “psm.exe”.

To run the locally installed PSM from a hard-drive, start WiJET.G PSM program located
under the Programs Folder in the Windows Start menu, WiJET.G Utility as shown in
Figure 3.2. You can also double-click on the WiJET.G shortcut on Windows desktop to
start PSM.

3.5 Configuring the Wireless Adapter to Connect WiJET.G

3.5.1 Configure the Wireless Network Adapter

Look at the banner page on the projector/monitor screen in your meeting room to
determine the SSID and the channel that the WiJET.G is currently set on. The channel
number ranges from 1 – 11 for the US or 1 – 13 for Europe.

By default, WiJET.G operates as an AP (Access Point). When the WiJET.G starts up,
the SSID of the WiJET.G will be displayed on the upper left corner of the
monitor/projector. You should configure your Wi-Fi wireless network adapter so that it
connects to the SSID of WiJET.G. There are many ways to configure the wireless
adapter cards. The following is an example sequence.

Open the Wireless Configuration Utility program (which may be called a different name)
provided by the manufacturer of the Wi-Fi wireless network adapter and modify the
settings as the following:

1. Change the network type to “the “Infrastructure” mode.

2. Change the “SSID” of the wireless network adapter so that it matches the SSID of
WiJET.G

3. Observe the wireless signal indications on the wireless configuration program to
make sure there is an active wireless link between the wireless network adapter
and the WiJET.G.

3.5.2 Configure the Wireless Adapter for Windows XP

To configure your Wireless Network Adapter for Windows XP, you must first know if
your Wireless Adapter 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 3.9.

Figure 3.9 Network Adapter with native support under Windows XP

If your system tray looks like the figure shown in Figure 3.9, your wireless card is
natively supported under Windows XP and you should read the rest of this section. It
will instruct you on how to connect your wireless adapter to the WiJET.G under
Windows XP. If you do not have the addition Wireless Network Connection icon in your
system tray as shown in Figure 3.9, you should check if you have any Wireless
configuration utility in your system tray instead, as in Figure 3.10.

WiJET.G Technical Manual

3.6 WiJET.G Running as Infrastructure Station

The WiJET.G can run as a Wi-Fi Infrastructure station and join an existing Wi-Fi
Wireless Network. The benefits include that several WiJET.G units can join the same
wireless network and thus the users can use the one-to-multiple display feature (one PC
sending screen image displays to multiple WiJET.G units) For how to configure the
WiJET.G running under Infrastructure station mode, please refer to the Web-based
Administration Utility Configuration section in Chapter 4.

3.7 Start or Resume Your WiJET.G Presentation Session

Once you have successfully configured the wireless card to connect to the WiJET.G and
when it is your turn to make a presentation, click “Establish a Session” and you should
find yourself connected to the WiJET.G. There will be a confirmation window alerting you
that your session is on, and your projector or monitor should now display your Desktop.

Figure 3.17 WiJET.G Presentation Session Manager

Various abnormal conditions, such as RF interference or network time-out, however
rare in occurrence, can cause the communication between the WiJET.G and the PSM
to be interrupted. If an interruption of session is detected, WiJET.G will automatically try
to reconnect and keep the user in session. In case of failing to keep the use in session,
WiJET.G will return to the banner page and be available for a new session. Certain
abnormal conditions that cause interruption of the link may be localized on the current
presenter’s computer and/or its wireless card. If the anomaly persists but can be
localized on the current presenter’s computer system, another presenter can still make
use of the projector/monitor by clicking the “Establish a Session” button on his/her
PSM.

Note: If the PC resolution is above 1024x768, the following message will be

displayed.

following selection box will appear when establishing a session. Select the desired unit
and establish a session accordingly. If multiple WiJET.Gs are available, multiple users
may connect to any combination of available units.

Figure 3.19 Select Unit to Connect

3.7.2 “WiJET.G is currently in session” Message

Another presenter may have an active session with the WiJET.G you are trying to
connect. In this case, a message box indicating that WiJET.G is currently in session
will be displayed for your information.

3.8 Release Your WiJET.G Presentation Session

If at any time you wish to release your computer from the WiJET.G, simply bring up the
WiJET.G PSM and click on the “Release a Session” button. The wireless connection
to the WiJET.G stays alive after clicking the “Release a Session” button so a presenter
can quickly get back to another turn of presentation.

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.

Chapter 5: TROUBLESHOOTING

5.1 Unable to Connect or Establish a Session with WiJET.G

If you could not establish a session with WiJET.G(s) and get a message box indicating
no WiJET.G is available for connection or no WiJET.G is found, the possible causes
are listed below.

1) The SSID of the wireless adapter is not set up to be the same as the
WiJET.G’s.

2) The computer’s Wi-Fi Adapter is not set to Infrastructure Station mode.

3) The computer’s Wi-Fi Adapter is not set to use the same encryption
settings as WiJET.G, if WiJET.G’s default encryption settings were
changed.

4) The WiJET.G is somehow not receiving the wireless signal, power-cycle
the WiJET.G.

5) Some DHCP-enabled wireless network connection client may take a
while to obtain a valid OS-assigned IP address. You can use “ipconfig”
command to see whether a valid IP address has been assigned or not to
the corresponding network connection.

6) With certain brands of PCMCIA 802.11g Wi-Fi cards, it might take a bit
longer to link up with the WiJET.G 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.G and the
computer to take longer. Simply try to establish a session again. If the
same issue persists, there probably is no link established between the
WiJET.G and the computer.

5.2 The Presentation screen appears frozen during a presentation

This indicates that WiJET.G has detected a link-loss. WiJET.G and WiJET.G PSM have
an intelligent built-in mechanism to detect the link-loss and can automatically restore
the connection by coordination. When a link-loss has been detected, WiJET.G PSM
displays a message box and trying to automatically restore the connection. If the auto­reconnection attempt is successful, user does not need to do anything. In this case, the
auto-reconnection is user transparent. However, if the cause to the link-loss is due to
physical disconnection, for instance, the PCMCIA card was pulled out, user needs to
restore the physical connection so that the auto-reconnection attempt can succeed.
The presentation screen won’t be updated once the link is lost, unless a reconnection
is re-established. However, if link-loss stays for an extended period, the WiJET.G will
terminate the reconnection waiting state and display the banner page indicating that a
fresh presentation session is ready for being established.

The default duration for a link-loss is 8 seconds. WiJET.G will retry 3 periods of this
duration. If no re-connection is established before the reconnection time running out,
WiJET.G returns itself to the banner page.

WiJET.G Technical Manual

5.3 The WiJET.G Session is Interrupted During a Presentation

This signals that the WiJET.G has detected a link-loss for an extended period of time or
severe communication error. Since the WiJET.G is designed to support one
presentation at a time, the WiJET.G cleans up the communication error and 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.G from being locked up with one possibly
malfunctioning user computer. With the auto-reconnection feature, this rarely occurs.

When this condition occurs, follow the steps below:

1) The current presenter should click “Establish a Session” 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 “Establish a
Session”, another presenter should try to “Establish a Session”. 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 “Establish a Session” to the WiJET.G, a
persistent abnormal condition has to be identified. Follow other trouble-shooting
tips in this chapter to identify the persistent abnormal condition.

5.4 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.G 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.G away from the microwave oven and large

metal objects.

• Consult the dealer or an experienced radio technician for help.
