5. Installation
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.
DNS server
Computers, Projectors, Touch panels connected to a network are referenced by their IP ad-
dress. The only problem is that remembering IP addresses is not easy. If you need to use
hundreds of addresses then it will become impossible to remember them. This is why domain
names are created. Internet names (domain and host names) are just aliases to these IP ad-
dresses. When you use an Internet address it is automatically translated to an IP address. In
fact a program or device that translates those Internet names to IP addresses is called a DNS
Server.
Host name
This is the name that will be returned, along with the IP address in response to the UDP broad-
cast query for projectors/touch panels.
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 organi-
zation'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 ad-
dress 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 ad-
ministrator 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.
UDP
User Datagram Protocol
What should be set up for the Ethernet address
2 ways can be used to assign addresses:
• use the DHCP setting so that a automatic address will be assigned.
• Assign manually an IP address, Subnet-mask, default gateway and DNS server address.
- Set the IP-Address field to the desired value. This must NOT be 0.0.0.0 for static IP-Address as-
signment. The IP address identifies a projector's location on the network in the same way a street
address identifies a house on a city block. Just as a street address must identify a unique residence,
an IP address must be globally unique and have a uniform format.
- Set the Subnet-Mask as appropriate for the local subnet.
- Set the Default-Gateway to the IP-Address of the local router (MUST be on the local subnet!) on
the same network as this projector that is used to forward traffic to destinations beyond the local
network. This must not be 0.0.0.0. If there is no router on the projector's local subnet then just set
this field to any IP-Address on the subnet.
- Set the DNS server address to the IP address if the DNS server obtained from your network ad-
ministrator or Internet Service Provider. That address can be any address.
