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).

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

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).
