Using the DPG-2000W
Using the DPG-2000W in a Meeting
Using the Presentation Session Manager (PSM) software provided, presenters
can easily display their presentations with a single click from any wirelessly-
enabled PC or laptop. The following steps demonstrate a typical scenario in an
office setting:
1.
Copies of the DPG-2000W installation CD are kept with the
DPG-2000W
in the meeting room. Prior to a meeting, participants can either run or
install the PSM onto their system. The installation is automatic and does
not require participants to reboot the computer.
2.
Meeting participants can then establish a wireless connection to the
DPG-2000W
. This wireless connection is maintained throughout the
meeting even if only one presenter can use the projector or monitor at a
given time by connecting through the PSM. Confirming wireless
connections before the meeting starts assures a smooth presentation
session.
3.
At any give time, by clicking just one button in the PSM, the first presenter
can start the presentation.
4.
When finished, with a single click, the incumbent presenter yields the
floor (the projector/monitor) to another presenter while still maintaining
a wireless link to the
DPG-2000W
.
5.
A waiting presenter, with an already established wireless link, can
instantaneously take over the projector/monitor by connecting through
the PSM.

Starting the DPG-2000W
When the
DPG-2000W
is first turned on and connected to a projector or monitor,
a boot up sequence will follow. After about 30 seconds, the
DPG-2000W
will
display the following graphic.
The wireless settings will be displayed on top of the graphic and consist of two
lines. The top line displays the SSID and the channel number of the
DPG-
2000W
while the second line reports the channels currently in use by other
802.11g equipment around the
DPG-2000W
.

Depending on the type of RF activity detected, you will see any one of the
following messages displayed:
RF activities detected on other channels (none).
No other 802.11g channels detected in use other than the
DPG-2000W
. Your
connection to the
DPG-2000W
should be smooth and error free.
RF activities detected on other channels (8, 9).
Existing 802.11b channels detected in use, but there is no interference. Your
connection to the
DPG-2000W
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
DPG-2000W
is in a RF
noisy environment, you may have trouble connecting and maintaining
connections to the
DPG-2000W
even if a connection can be made.
Note:
The
DPG-2000W updates this information whenever the banner page
appears on boot-up. In a noisy environment, channel information might get
outdated quickly since the DPG-2000W does not monitor channels continuousl
y.
Once you have turned the
DPG-2000W
on and noted the above information,
you can now configure your computer to connect to the
DPG-2000W
.
Establishing a Link with the DPG-2000W
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 a valid IP address for the network
interface cannot be obtained, please refer to a network administrator for how to
assign an IP address.
Note:
The computer’s network interface must have a valid IP address before
PSM starts.

Using Your Wireless Configuration Utility
Select the SSID matching
the
DPG-2000W
’s SSID
displayed on the banner
screen.
The banner page on the projector/monitor screen will display the SSID and the
channel that the
DPG-2000W
is currently set on. The channel number ranges
from 1 – 11 for the US or 1 – 13 for Europe and Japan.
The
DPG-2000W
operates as an Access Point (AP), with an SSID automatically
assigned at each boot up. When the
DPG-2000W
starts up, its SSID will be
displayed on the upper left corner of the monitor/projector.
Wireless configuration will vary depending on the manufacturer of the wireless
card that you are using. Open the Wireless Configuration Utility program (which
may be called a different name) provided by the manufacturer of your wireless
card and modify the settings as follows:
Change the network type to “Infrastructure” mode.
Change the “SSID” of the wireless network adapter corresponding to
the
DPG-2000W
’s SSID displayed on the banner page.
Your wireless configuration utility will indicate if a proper wireless
connection is established between the wireless card and the
DPG-
2000W
.

Windows XP Users
To configure your Wireless Network Adapter for Windows XP, your Wireless
Adapter must be natively supported under Windows XP. The easiest way to
determine native support is by the network icon in your system tray as seen
below.
If your system tray looks like the figure shown above, your wireless card is
natively supported under Windows XP. If you do not have the additional
Wireless Network Connection icon in your system tray as shown above, you
should check if you have a Wireless configuration utility icon in your system
tray.
Right-click the wireless
network connection icon
in the system tray and
select “View available
networks.”
Click Properties.
