ETHERNET CONFIGURATION
The Dica 220 can be used in an Ethernet network. This
network can be used exclusively for connecting this
camera and other Dica 220 cameras to a PC or it can be
part of a much larger existing network with multiple PCs
and other Ethernet devices and cameras
3.1
TCP/IP
The Dica 220 makes use of TCP/IP, which is a routable
protocol. Every client in a TCP/IP network requires a
unique IP address, which can be assigned either
permanently to the camera or dynamically via DHCP
(Dynamic Host Configuration Protocol), meaning that it
draws from a pool of addresses each time the camera
starts up.
3.2
Configuring TCP/IP
The TCP/IP protocol of the network adapter to which the
Dica 220 is connected needs to be configured properly.
When the PC and the Dica 220 are part of a larger network
contact your network administrator for assistance.
To configure the TCP/IP protocol right click on "My
Network Places" which can be found in the Start menu
(Windows XP) or on the desktop. Then choose
"properties". A list of available LAN connections will be
displayed. Right click the connection to which the Dica 220
camera(s) are connected and choose "properties". Then
click the TCP/IP protocol and click the "Properties" button.
In the general tab there are two options available.

The option "Obtain an IP address automatically" is used
when a DHCP server is available on the network that
distributes IP addresses (contact your network
administrator for this).
The second option allows you to fill in the IP address when
DHCP is not used.
In the IP address range there is one range that can be
freely used on local networks. This is the range
192.168.10.xxx, where xxx needs to be a unique number
ranging from 1 to 255 in that local network. Depending on
the configuration and the device-id of the Dica 220 it can
have a value between 1 and 127. Because of this it is best
to assign a number larger than 127 for the PC you are
configuring, like 192.168.10.200.
The subnet mask is normally 255.255.255.0 and needs to
be changed only in special cases. For more information
about how the Dica 220 determines what IP address to use
see chapter 2.5.1.
3.3
Port Number
Every package that is transmitted over Ethernet, is
accompanied by a port number. The port number used by
the Dica 220 is 3813.
3.4
Special configurations
On the host PC it is possible to create a special (optional)
initialization file, which can be used to configure some of
the special cases. This file is named RapEthernet.ini and
needs to be stored in a location that can be found by the
software (normally "Program Files/IV/Shared/Bin").
