Terminology
802.11 AD-HOC (Peer to Peer) mode
This is the mode in which computers communicate with each other directly, rather than
via access points.
Access point
These are stations for relaying electromagnetic signals between computers in a
wireless LAN. When a computer is connected to an access point, it can communicate
through the network connected to the access point.
DHCP
Abbreviation for Dynamic Host Configuration Protocol. This function automatically
assigns IP addresses to the connected equipment. If a device with the DHCP server
function is present within a LAN, it automatically assigns IP addresses to the
connected equipment. 
Gateway
This is a relay point for connecting different networks.
This refers to the hardware and software used when connecting a network with a
network that uses a different protocol, etc. It adjusts the protocol and other differences
between networks to allow connection with other networks.
Infrastructure mode
This is the mode in which communications are performed via the access point.
IP address
Internet Protocol (IP) is a protocol for distributing data, and the address corresponding
to the data distribution destination is called the IP address. The same IP address
cannot be used within the same LAN.
LAN
Abbreviation for Local Area Network. This is a network with a relatively narrow range
such as inside a company. There are wired LAN and wireless LAN.
Open System
This is an authentication of wireless signals employing a public key cryptosystem. 
						

							47
Shared Key
This is a secret key encryptosystem for wireless signals in which authentication is
performed with a key pre-set in the WEP.
Other terms for this method, in which the same key is used for both encryption and
decryption, are “shared key encryptosystem” and “common key encryptosystem”.
SSID
Abbreviation for Service Set ID. The SSID identification code must be set to distinguish
equipment included in a wireless LAN that uses access points from equipment not
included in that LAN.
This may appear as the “ESSID” or the “network name” for wireless LAN cards made
by some manufacturers.
Subnet mask
This limits the range of the IP addresses assigned to computers in order to divide the
network into a number of sections during TCP/IP connection. The value used to divide
the network at this time is called the subnet mask.
TCP/IP
Abbreviation for Transmission Control Protocol/Internet Protocol. This is the standard
internet protocol.
This protocol is a set of rules and agreements governing data communications
between computers.
WEP
Abbreviation for Wired Equivalent Privacy. This is a method for encrypting
communication data. The encryption key is created and notified only to the
communicating user, so the communication data cannot be decrypted by a third party.

Frequently Asked Questions
Check the following points once more before requesting repair.
The transfer rate is slow.
•The transfer rate may be slower in some operating environments (depending on
such factors as the location, radio signal conditions or distance).
•Avoid placing metal objects or other conductors near the wireless LAN antenna
of a personal computer, otherwise the transfer rate may be slower.
•When WEP is set the image data is converted, so transfer takes time.
Image display is slow in live mode.
•Is the computer CPU speed slow?
Live mode depends largely upon the computer CPU performance.
•When using Windows 2000/XP, the speed may drop significantly if the user
does not have administrator authority.
•The speed may be slower when any other applications are running concurrently. 
The Wireless Manager ME 2.0 color display is strange and characters are difficult to read.
•Right-click an empty location on the desktop and select [Properties]. Then, open
the [Settings] tab of the [Display Properties] window and set [Color quality] to
[Medium (16 bit)] or higher.
Screen saver is not displayed properly in live mode.
•Some screen savers may not be displayed properly in the live mode.
Disable screen saver function using [Live Mode Settings] in Options of Wireless
Manager ME 2.0. (See pages 24, 25.)
Movies are slow in the live mode.
•Did you start up Microsoft PowerPoint or Windows Media Player before starting
up Wireless Manager ME 2.0?
If so, start up the application only after you have started up Wireless Manager
ME 2.0.

Frequently Asked Questions(cont.)
No wireless connection can be made between my projector and my computer. (cont.)
•Is Wireless Manager mobile edition 2.0 running?
Wireless Manager mobile edition 2.0 must be started in the computer in order to
enable wireless transmissions of images to the projector.
•Is the wireless LAN card effective?
Even if your computer has integral LAN, the wireless LAN may still be turned
OFF. If so, turn it ON and re-start Wireless Manager mobile edition 2.0. See the
User’s Manual of your computer to learn how to turn the wireless LAN power
ON/OFF.
•Is your wireless LAN card properly recognized on the network?
Sometimes, cards are not correctly recognized by the network. Check Windows
“Device Manager” to make sure your card has been recognized.
If the Network Adapter is indicated with “?” in [Device Manager], LAN card
installation is not complete. See the User’s Manual of your card and re-install
the card driver.
To display “Device Manager”
Right-click [My Computer] on your desktop (Windows XP – in your [Start] menu)
and choose [Properties] in the menu. This will bring up the [System Properties]
dialog box.

Click the [Hardware] tab and then [Device Manager].

Click the [Device Manager] tab.
•Some wireless cards may allow simple connections to function if drivers are
updated (consult the manufacturer of your driver about updates).
