Panasonic Part For Network Functions And SD Memory Card Functions PT-L735NTE Manual

							71
Explanation of terms
LANAbbreviation of Local Area Network, including wired LAN and wireless LAN; a
relatively small-range network developed in a company or in a building.
TCP/IPAbbreviation for Transmission Control Protocol/Internet Protocol. The standard
protocol for the Internet.
A protocol is a set of specifications and agreements which allow two computers to
communicate with each other.
IP AddressAn Internet Protocol (IP) is a protocol used for the transmission of data, and the IP
address is the address of the destination where the data is being sent to. Identical IP
addresses cannot be used for two different devices within the one LAN.
Subnet MaskLimits the range of IP addresses that can be assigned to a computer when using a
TCP/IP connection, in order to allow a network to be divided into several sub-
sections. The parameters which divide the sub-network in this way are called the
subnet mask.
GatewayA junction point where different types of networks are connected to each other.
It is used to refer to the hardware and software which is used when connecting a
particular network to another network which has been set up under different network
specifications. It makes adjustments for differences in the protocols used by the two
networks and makes it possible to connect to other networks.
DHCPAbbreviation for Dynamic Host Configuration Protocol. 
A function to automatically assign an IP address to connected devices. If a device
having functions of DHCP server is detected within the LAN, an IP address is
automatically assigned to each of connected devices. This function is not supported
by the projector side.
Ad Hoc ModeThis mode allows direct communication between the projector and a personal
computer having a wireless LAN inside or a personal computer to which a wireless
LAN card is fitted. It is necessary to establish a common channel both to the projector
and the personal computer. Some cards are not compatible to this mode.
Infrastructure ModeThis mode allows communication via an access point connected to a wired LAN.
Even a personal computer to which any wireless LAN card is not fitted can transfer
images to the projector via an access point.

802.11 Ad Hoc (peer-to-peer) ModeThis mode allows direct communication between the projector and a personal
computer having a wireless LAN inside or a personal computer to which a wireless
LAN card is fitted. It is necessary to make settings of SSID.
Access PointA point of connection between a wired LAN and a wireless LAN.
ChannelIf several access points which use the same frequency band are located near each
other, radio transmission interference between these access point can occur when
they are being used, and this can in turn result in drops in transmission speeds. In
order to reduce this problem when using wireless LANs, the frequency band can be
divided into 11 channels for communication purposes. (The number of channels
varies depending on the country.) However, because interference between adjacent
channels can occur, the channels available for use are normally spaced 2 or 3
channels apart from each other.
SSIDAbbreviation for Service Set ID. Wireless LANs that utilise access points require the
setting of SSID identification codes in order to distinguish between devices which are
a part of the LAN and devices which are not.
Wireless LAN cards of some manufacturers use the name of “ESSID” or “Network
name” instead of SSID.
WEPAbbreviation for Wired Equivalent Privacy. A method of encrypting transmitted data.
An encryption key is generated and is given only to the person who will be using the
transmitted data, in order to prevent third parties from decoding the transmitted data.
Not available with this product.
JPEGAbbreviation for Joint Photographic Experts Group. JPEG is the name of an
international organisation which was jointly established by the ISO and the ITU-TS
(formerly the CCIT), but the term is normally used to refer to the specifications for the
still picture compression algorithm which was formulated by the JPEG. This algorithm
allows still images such as photographs, single frames of moving images and
scanned images to be compressed to up to 1/100th of their original sizes. However,
images which are compressed in this way cannot be fully restored to their original
quality (some deterioration in quality occurs), so that compression rates of 1/5 to 1/30
are normally used. Because of differences in color separation, two format sub-types
are used: RGB (red, green and blue) and CMYK (cyan, magenta, yellow, black).
The projector and the Image Creator 1.0 software do not support the CMYK sub-type
of JPEG file.
BMPAbbreviation for BitMaP. This is the standard image format for the bitmapped files
(image files consisting of a collection of dots) which are handled by Windows.
Color levels of monochrome, 16 colors, 256 colors and 16.7 million colors are
supported.
Explanation of terms 
						

							73
PNG Abbreviation for Portable Network Graphics.
A high compression rate file format that provides restorable compression for line
raster images.
Because it uses restorable compression, it does not result in any loss of image
resolution unlike JPEG.
RLEAbbreviation for Run Length Encoding. It can be used to achieve high rates of
compression for image files which contain large areas of a single colour. RLE can be
used with monochrome, 16-colour and 256-colour BMP image files. (Image Creator
1.0 does not support files compressed using RLE.)
TIFFAbbreviation for Tagged-Image File Format. This type of file is used to exchange
documents between computers. Colour levels of monochrome, 256 colours and 16.7
million colours are supported. TIFF files in 16.7 million colour format can include
transparent colour.
LZWAbbreviation for Lempel-Ziv-Welch. LZW is a compression method used for TIFF
files, and is named thus because it was developed by three people named Lempel,
Ziv and Welch. It compresses the files by converting patterns within the images into
short codes. There is no deterioration in image quality resulting from compression,
but high rates of compression which are comparable to JPEG files cannot be
expected to be obtained. (Image Creator 1.0 does not support files compressed using
LZW.)
DCFAbbreviation for Design rule for Camera File system. DCF is a standard which was
established by the Japan Electronic Industry Development Association (JEIDA) with
the aim of realising a common image file format, directory name format and file name
format for the images used with digital still cameras. It is based on recommendations
such as Exif Version 2.1.
Exif 2.1Abbreviation for Exchangeable Image File Format. This is an image file format which
was established by the Japan Electronic Industry Development Association (JEIDA).
It defines the common information format and range of application for images used
with digital still cameras, centering around TIFF and JPEG-format images. Version
2.1 is the latest version of the Exif standard.
PowerPointApplication software for creating presentations which is included as part of Microsoft
Office. 95, 97, 2000 and 2002 versions are available, but the Image Creator 1.0
software which is bundled with the projector is only compatible with the 97, 2000 and
2002 versions.

recognize the SD
card.
Writing cannot be
performed.
The image from
the PC is not
displayed.
The PC does not
recognize the
wireless card.
Transfer rate has
become lower.• Is the PC card adapter inserted into the PC card slot of the
PC until it reaches the end?
• Is the SD card inserted into the SD card slot of the PC card
adapter until it reaches the end?
• Is the driver installed?
• Are there sufficient IRQ (interrupting signal) numbers?
(Refer to the online help of Windows.)
• Is the write-protect switch of the SD card set to LOCK?
• Is the external video output of the notebook computer
properly selected? (In some cases, the setting of the output
is changed if Fn and F3 buttons are pressed simultaneously.
Since this depends on the model, refer to the instruction
manual supplied with your PC.)
• Is the wireless card inserted into the PC card slot of the PC until it
reaches the end?
• Is the driver installed?
• Had the driver been installed before the wireless card was inserted?
• Are there sufficient IRQ (interrupting signal) numbers? (Refer to the
online help of Windows.)
• If WEP is enabled, transfer operation takes a longer time
because the image data needs to be converted.
• If another wireless device uses the same channel, the
transfer rate may become lower. Select other channel for
setting.
Images displayed
too slow in live
mode• Does the personal computer CPU operate fast enough?
Operation in live mode depends on the performance of
personal computer CPU.
• With Windows XP/2000, the operation speed may decrease
remarkably but for the Administrator authority.

images and some of them cannot be displayed.
Before placing a repair order
• Immediately after the projector is turned on, it is on the way
to establish the network communication. Perform the search
again after a while.
• Check whether the distance is too far between the PC and
the projector, or if any obstacle between is making the radio
waves unstable.
• Make sure that the IP address and the subnet mask are
correctly assigned.
• Is TCP/IP installed in your personal computer?
• Does the WEP setting correspond with that of the projector?
Communication with the projector cannot be established if
the WEP function was enabled when a third-party wireless
card was used or the access point was used. Disable the
WEP function.
• In the Infrastructure mode, use the same setting for the
projector and the PC as the access point SSID.
Alphanumeric characters (case sensitive) can be used for
an SSID. Make sure that the user is not using the function
for controlling PCs that can communicate with the access
point.
• In [802.11 ad hoc (peer-to-peer)] mode, the SSID must be of
the same settings both for the projector and the personal
computer. In addition, SSID is case sensitive.
• Is any network device other than the wireless card enabled?
Check with the device manager of Windows.
• Check if the proxy-client software is in operation. Disable
the software when communicating with the projector.
