A third party equipment could be a TMS, an automation device, an IMB/IMS installed in the projector or any
other equipment which need to operate the Freya projector. The commands available are controlling the basic
features of the projector such as Light ON/OFF, Dowser Open/Close, Execute Macro

Discard button (reference 7) allows to restore last configuration (removing unsaved user modifications).
Save button (reference 8) allows to save modifications.
Ethernet Connections
Ethernet is a networking technology commonly used to communicate with local area network (LAN) and wide
area network (WAN). This protocol requires an IP address, Subnet-mask, default gateway and DNS server
address.
These parameters can be automatically applied from DHCP server or need to be adjusted manually.
IP
Internet Protocol. The network layer of TCP/IP. Required for communication with the internet.
A new projector is delivered with a default IP address : 192.168.100.2
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.
DNS server
Computers, Projectors, Touch panels connected to a network are referenced by their IP address.
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 addresses. 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 broadcast
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 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.
UDP
User Datagram Protocol
