Wireless projection
Introduction
This section will introduce wireless projection function for this projector. The
wireless projection function is only available for the model which is equipped
with integrated Acer Wireless Presentation Gateway (WPG) module. Acer WPG
enables multiple users to connect to an Acer projector wirelessly. This eliminates
the need to plug and unplug cables, enabling more efficient use of meeting time,
especially when there is more than one presenter in a meeting.
To perform wireless projection, you have to change the input source type to
“Wireless” by pressing the “Wireless” button on the remote control or the
“Source” button on the control panel or remote control.
System Requirements:
- Operating system: Windows® 2000 or Windows® XP
- CPU: Intel® Pentium® III at 750 MHz or equivalent with 128 MB of RAM
- Wireless LAN: IEEE 802.11b/g enabled
- Internet Browser: Internet Explorer 5.0 or above

Wireless projection
Setting up your WPG
Check the LED for the power status.
• Red indicates that the WPG is receiving power, but is inactive.
• Green indicates that the WPG is being used to project images.
You may also like to connect a LAN cable to the LAN (RJ-45) port on the side
of the dongle. This will allow you to connect to the Internet to retrieve interactive content or download firmware upgrades as they become available.
Connecting to the WPG for the
first time
If this is the first time you’ve connected to the WPG, you will need to
download and install the driver from the WPG. The software is stored
on the WPG, so there is no need for an installation CD. Ensure that
you have administrator-level permission on your computer so that
you can install the software.
To download the software, you must ensure that your browser
is set to open up a website. If your browser is set to open with a
blank page, you will not be able to download the software. To
check this, select Tools > Internet Options. Ensure that there is a
website in the text box.
English ... 36
Wireless projection
Downloading the software
1)
Switch on your notebook, and activate the wireless LAN.
2)
Scan for available WLAN APs using your preferred WLAN manager.
3)
Select the AP labeled “AcerProjector” from the list of available APs.
Connect to this AP. If there is more than one WPG listed, determine
which one is the one you want to connect to from the SSID listed in
the upper left-hand corner of the screen.
4)
If you receive any security warnings, select “Connect Anyway”.
5)
Once the connection is established, open your Internet browser. You
will automatically be taken to the Acer WPG welcome page, where
you will be able to download the driver.
37 ... English
Wireless projection
6) Click on the link to download and install the driver. If you receive
any security warnings, click “OK” to proceed with the installation
procedure. During the driver installation, your screen may flicker.
7) Once the installation is complete, the Acer Wireless Projection Gateway software will open.
English ... 38
Wireless projection
Connecting to a projector
Once you’ve installed the software, you will be able to connect to any projector
that is equipped with the Acer WPG. To connect to a projector, simply doubleclick the Acer WPG icon on your desktop to launch the application.
The application will automatically detect available WPGs. Each WPG is identifiable by the “AcerProjector” indicator in the SSID. If the projector is installed
in a permanent location, you may also choose to assign a specific SSID to that
projector, indicating, for example, the number of the room in which the projector is installed (refer to “Configuration” later in this guide).
If there are multiple WPGs within the range of your notebook's receiver (they
may be in different rooms), and the feature is enabled (refer to “Configuration”
later in this guide), you will be able to identify the correct one by the “Projector
ID” indicated in the top left-hand corner of the projected screen. The Projector
ID consists of four randomly-generated numbers. Entering these numbers into
the WPG application on your notebook will restrict your connection to only
that projector.
Only one user can use the WPG at any time; if another user wishes to use the
projector, you will need to click Disconnect to stop using the projector, and allow someone else to use the projector.
39 ... English
Wireless projection
Using the audio function
If “Wireless” is selected as the input source, you can play audio content
through the internal speakers of the projector. You can also plug external
speakers into the WPG’s audio-out jack for better audio quality.
Your audio driver may have different terminology for some of the settings required below.
If you wish to use the WPG’s audio features, please ensure that none of
the audio settings is muted.
To set up the audio, you must perform the following steps:
1) Open the Windows® audio controls by double-clicking on the speaker
icon in the task tray.
2) Select Options > Properties.
3) Select Recording in the “Adjust volume for” area.

Configuring your Acer WPG
You will need to be connected to an Acer WPG to change any configuration
settings. Once you're connected, click the Configure button in the upper righthand corner of the Acer WPG screen.

Check this feature to enable projector identification. If this option is enabled, a
4-digit number will be displayed when the projector is started up, or when the
projector is not receiving any input.
Configuration password setup
Use this to set a password to restrict access to the configuration menus. This
is useful when the WPG is used by a number of people, and you do not wish
unauthorized persons to make any changes to the configuration.
The first time you click on this link, you will see the following:
English ... 42
Wireless projection
Click on Set a new password to set a password.
Enter the password — it can be up to 16 characters in length.

need to be connected to a network with an open Internet connection to do this.
Network settings
Click on this link to change the network settings.
Here, you can set a customized SSID to identify the Acer WPG. You can also
change the IP address — either set it to automatically obtain an IP address, or
manually set a static IP address.
If necessary, you can set the RF channel used to connect with notebooks as
well.
