10.3 LAN Communication
About a network connection
Network connection is required to communicate with the projector via LAN or Internet. The setup could be
done manually (set address, subnet mask and default gateway according to network specification), or
automatically assign (DHCP).
10.3.1 Introduction to a Network connection
DHCP
Dynamic host configuration protocol. DHCP is a communications protocol that lets network
administrators manage centrally and automate the assignment of IP addresses in an organization's
network. Using the Internet Protocol, each machine that can connect to the Internet needs a unique
IP address. When an organization sets up its computer users with a connection to the Internet, an IP
address must be assigned to each machine. Without DHCP, the IP address must be entered
manually at each computer and, if computers move to another location in another part of the
network, a new IP address must be entered. DHCP lets a network administrator supervise and
distribute IP addresses from a central point and automatically sends a new IP address when a
computer is plugged into a different place in the network.
IP
Internet Protocol. The network layer of TCP/IP. Required for communication with the internet.
Subnet mask
A number that is used to identify a subnetwork so that IP addresses can be shared on a local area
network.
Default Gateway
A router that serves as an entry point into and exit point out of a network. For example, a local
network (LAN) may need a gateway to connect it to a wide area network (WAN) or to the Internet.
MAC address
Media Access Control address. Unique hardware number, used in combination with the IP-address
to connect to the network (LAN or WAN).
