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.

Installing the Hardware
Power
Power is supplied to the WiJET via a 1.7 amps 5volt DC power adaptor.
WARNING: Do not exceed more than 12A@120VAC/10A@240VAC total
current connected to the WiJET!
VGA Connection
This is a standard 15 pin female VGA connector where you will connect the WiJET 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 monitor).
Status LED’s
There are two status LED’s on the WiJET. 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 is ready for connection to a PC. Upon connection
from a computer, the LED will turn solid green. Upon disconnection, the LED will revert
back to blinking red again.
Hardware Reset Button
The hardware reset button is located at the back of the WiJET. It requires a bent paper
clip to access the hardware reset switch.
The hardware reset button has two functions. The first function is to reboot the WiJET,
the second function is to set the WiJET back to its factory default.

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.).
