Explanation of terms
LAN
Abbreviation of Local Area Network, including wired LAN and wireless LAN; a
relatively small-range network developed in a company or in a building.
TCP/IP
Abbreviation 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 Address
An 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 Mask
Limits 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.
Gateway
A 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.
DHCP
Abbreviation for Dynamic Host Configuration Protocol. A function which automatically
assigns IP addresses to each computer that is connected to a network. If a device
which functions as a DHCP server is located within a LAN, this device automatically
assigns IP addresses to computers which are connected to the LAN. Not available
with this product.
Ad Hoc Mode
A mode for direct communication between the projector and a computer with an
optional wireless card.
Infrastructure Mode
A mode for communication via an access point which is connected to a wired LAN.
A computer without an optional wireless card can still be used to send images to the
projector via an access point.
PEER-TO-PEER Mode
A mode that allows direct communication between the projector and a wireless LAN-
incorporated personal computer produced by some manufacturers or a wireless LAN
card. If communication is not available in ad hoc mode, try to use this peer-to-peer
mode.
