Introduction
Functions
The EP8790NET wireless network module is equipped with the latest network functions. You can use
the EP8790NET module in combination with 3M MP8790 Multimedia Projector to make presentations
that draw on the power of your network. In addition, the wireless LAN card (*1) allows you to connect
the EP8790NET module to your network without the need to connect any annoying LAN cables.
(*1): Please use the wireless LAN card that came with your EP8790NET.
<Major Functions>
1. Live Mode
The EP8790NET module gives you the power to present PowerPoint® and other presentations with
ease and in a cable-free environment.
Get your computer ready to go! Using the EP8790NET module with PCs that are equipped with the latest
wireless LAN functions allow you to project images from your PC in real time (*2) using wireless
transmission to project a large screen with the same feel as a live broadcast.
No more annoying cables! Not only that, but you can project presentations from multiple computers at
the same! In addition, you can now project a presentation from one computer to multiple projectors.
(*2): This will depend on the type of images you are attempting to display. Images are refreshed at a rate
of every one to four seconds. Therefore, you might not be able to project extremely dynamic images
such as animation very smoothly, and, in some cases, you may not be able to project them at all.
Office meetings at a snap of the fingers! Up to four PC screens can be displayed at the
same time.
Meetings in a wireless environment! In your showroom or at a convention hall.

2. Playback Mode
Images transmitted to the projector in Live Mode can be replayed from the projector side (*3).
You can also send images to the projector from the PC in advance (*4).
Regardless of the method chosen, you can select the image you wish to display or even select
multiple images for consecutive playback by viewing the corresponding thumbnail images
stored on the projector side (*5).
(*3): Use the key on your PC keyboard to capture images for replay in Playback mode.
(*4): Refer to for detailed information on how to use FileViewer.
(*5): Refer to for detailed information on how to use ImageViewer.
3. PC-less Presentation Mode (*6)
In order to use PC-less Presentation Mode, you need to store your presentation data (*7) into a
memory card (*8). Next, insert the memory card into the projector and you are all ready to make
a presentation with just the projector. No need for a PC! The presentation is played just as
described in Playback Mode.
(*6): Since there is only one card slot, you can't use the wireless LAN card when in this mode.
(*7): You can only use still image files of the following extensions: .jpg, .bmp and .png.
(*8): You can use any of the following types of memory cards:
PCMCIA compliant memory card
CF memory card (dedicated PCMCIA adaptor required)
SD card (dedicated PCMCIA adaptor required)
Memory Stick (dedicated PCMCIA adaptor required)
HDD card (ATA compatible; less than 2GB) (IDE compatible HDD cards can't be used)

Only memory cards under 2GB can be used. Memory cards formatted to 2GB or more can't be used.
Reformat memory cards to under 2GB as necessary. (Refer to your memory card user guide for details.)
NOTE
4. Remote Control Mode
The EP8790NET incorporates the latest LAN functions, enabling you to not only make presentations,
but also control the projector using a control panel that you interface to using your Web
browser. Remote control functions available include, turning the projector's power on and off,
and selecting between image sources.
This feature also provides you with such information as when the projector's lamp needs to be
replaced. Even if the projector is located in an office room away from your current location, you
can easily operate it via remote control.
If you opt not to use the wireless LAN card, you can still directly connect your computer
using a LAN cable. Be sure to use a cross cable when directly connecting to just one PC. Use
a straight cable for connecting to the closest hub of your company LAN.

[Explanation]
A network address setting is required as you will be connecting the EP8790NET module to
the PC using the network.
You can choose to manually assign an address to each device or have an DHCP server
automatically assign the address.
When configuring the address manually, please use the following setting:
IP address = 192.168.xxx.NNN
<xxx and NNN represent decimals>
Subnet Mask = 255.255.255.0
Be sure to use the same setting for the "xxx" portion of the IP address for both the EP8790NET
module and PCs.
Then "NNN" portion can be any number from 1 to 254, but be careful so as not to assign the
same number to two or more devices connected to the same network.
● If you are attempting a wireless connection, configure the network adaptor attributes as follows
(configure all the devices, including the projector that the EP8790NET module is mounted to, with the same setting):
❍Communication Mode
•If you won't be using an access point (Peer to Peer):
Set to AD-HOC (pseudo ad hoc) or 802.11AD-HOC (depending on the hardware).
•If you will be using an access point:
Select INFRASTRUCTURE.
❍Communication Speed: This is normally set to Auto (Full Automatic, et al)
❍Communication Channel: Depending on the country or region you are in, the
channels you can use may vary. Be sure to use the same
channel setting for each device.
❍SSID (network group name): Set the same name for all devices.
❍Encryption (WEP) Setting
•Disable if you won't be using encryption
•Enable if you will be using encryption by selecting the type of encryption [40(60)bit or
128bit] and configure the encryption key as well (text or hexadecimal)
Refer to your PC user guide and wireless LAN card user guide (if you are using a wireless
LAN card) for additional information on how to configure these settings.
If there is another network nearby, it is best to use a channel that is
at least four channels away from the other network.

This section explains how to combine images from multiple PCs onto a single projector at the
same time. You can use this function for two, three and even four PCs at a time.
•Open the WNM LiveViewer on each PC.
•Press the PLAY button and close down the LiveViewer dialog.
•Right click on the LiveViewer icon residing in the system tray and then click on Multi PCs.
•Select the number of PCs you wish to use at the same time.
You can adjust this setting from any of the participating PCs. The most recent setting made is
the one that is used.
•
What if the number of PCs set is higher than the actual number of PCs being used?
The images from the participating PCs are projected in the order of top left, top right, bottom left and bottom right.
So, until you have connected the maximum number of PCs (four), you can continue to add additional PCs.
•What if the number of PCs set is lower than the actual number of PCs being used?
For example, if you make the selection for four PCs and the actual number of participating PCs is four, but then you
change the setting to two PCs, only the images of the two most recently connected PCs will remain, with the image
from the first one of the remaining two PCs being projected on the left and the other one being projected on the right.
Can I mark multiple screen images for playback?
Yes. Simply press the Print Screen key when the multiple screen is displayed. The complete
multiple screen image will be saved in the projector's internal memory.
However, that images displayed using this feature will be projected at quarter of the normal size.
NOTE
Two PCs at a time Three PCs at a time Four PCs at a time
In the above example, the images of the first two PCs to be connected will disappear from the screen. However,
no matter what the order of display, if only one PC is selected, then its image will be displayed at full screen size.

Operations (continued)
<Applied Operation: Distributing Images to Multiple Projectors>
You can simultaneously distribute the images from a single PC to a multiple number of projectors(*1) (*2).
(*1): Each image from the PC is distributed in time-share fashion to each projector and then a synchronized
command is issued to have each projector refresh its screen simultaneously.
(*2): The PC can connect to projectors with the same network address. However, the greater number of
projectors involved, the greater delay in the image refresh rate.
•Press the PROJECTOR button from the LiveViewer dialog.
•A list of available projectors is displayed. Select the names (or as the case may be, the IP
address) of the projectors you wish to use (use a left mouse click while pressing the Ctrl key
to select more than one projector at a time).
•Press the PLAY button.
You are now ready to broadcast your PC screen to all the projectors you selected.

Since there is only one card slot, you can't use the wireless LAN card at the same time.
You can only store files of the following extensions in the storage card: .jpg, .bmp and .png.
Record the data you wish to present from your PC onto the storage card you will be using.
You can only use files located in the root directory. You can't not playback files located in a
subdirectory.
You can use digital camera storage cards.
