Network Configuration (IPv4)
This page allows you to configure network
details that are mainly related to the use of
the IPv4 protocol.
MAC Address
Media Access Control address – this is the unique and unchangeable code that
was hard coded within your AdderView CATxIP 5000 unit when it was built. It
consists of six 2-digit hexadecimal (base 16) numbers separated by colons. A
section of the MAC address identifies the manufacturer, while the remainder is
effectively the unique electronic serial number of your particular unit.
View Protocol
Allows you to change between options for IPv4 and
IPv6
. See the
next page
for
details about IPv6 options.
Use DHCP
DHCP stands for ‘Dynamic Host Configuration Protocol’. Its function is
particularly useful when connecting to medium size or larger networks.
When this option is selected, your AdderView CATxIP 5000 will attempt to
locate a DHCP server on the network. If such a server is located, it will supply
three things to the AdderView CATxIP 5000: an IP address, an IP network mask
(also known as a Subnet mask) and a Gateway address. These are not usually
granted permanently, but on a ‘lease’ basis for a fixed amount of time or for
as long as the AdderView CATxIP 5000 remains connected and switched on.

IP Address
This is the identity of the AdderView CATxIP 5000 within a network. It can either
be entered manually or configured automatically using the DHCP option. When
the DHCP option is enabled, this entry is unavailable. See
IP addresses

1 From a local keyboard, log on as the
‘admin’ user.
2 Press
(hotkeys can change).
3 Press to show the Main Menu.
4 Select ‘Configuration’ and press

5 Select ‘Network Configuration’ & press

Net Mask
Also often called the ‘subnet-mask’, this value is used alongside the IP address
to help define a smaller collection (or subnet) of devices on a network. In this
way a distinction is made between locally connected devices and ones that are
reachable elsewhere, such as on the wider Internet. This process helps to reduce
overall traffic on the network and hence speed up connections in general. See
Net masks
.
Gateway
This is the address of the device that links the local network (to which the
AdderView CATxIP 5000 is connected) to another network such as the Internet.
Usually this is a network router and it will be used whenever a device to be
contacted lies outside the local network.
VNC Port
This is the logical link through which communications with a remote VNC viewer
will be channelled (see
What is a port?
). The default setting is 5900 which is
a widely recognised port number for use by VNC software. However, in certain
circumstances it may be advantageous to alter this number - see
Security issues
with ports
for more details.
Note: The VNC port and HTTP port can be set to the same port number in order
to simplify router and firewall configuration. If this is done then the AdderView
CATxIP 5000 will “listen” for both types of traffic on the single port.
HTTP Port
This is the logical link through which communications with a remote web
browser will be channelled. The default setting of 80 is an established standard
for web (HTTP – HyperText Transfer Protocol) traffic though this can be changed
to suit your local network requirements.
Clear IP Access Control
This option removes all entries from the IP access control feature within the
AdderView CATxIP 5000. The IP access control feature (configurable by a global
admin user) allows certain network address ranges to be denied access to the
AdderView CATxIP 5000. If set incorrectly, it is possible to exclude all network
users and so this option provides an emergency recovery point.
