Network configuration
This menu allows you to configure the various aspects of the IP Input Modules and their relationship with the local
network. (Similar to the local network configuration procedure)
Figure 16. Remote Network Configuration
MAC address
Media Access Control address – this is the unique and unchangeable code that was hard coded within your
UltraMatrix Remote 2 unit when it was built.
Use DHCP
When Use DHCP is selected the UltraMatrix Remote 2 will attempt to locate a DHCP server on the network. If the
server is located, it will supply to the UltraMatrix Remote 2, an IP address, an IP network mask and a Gateway
address. Remote users must be informed of this IP address in order to connect to the UltraMatrix Remote 2 unit.
IP Address
The IP address can be altered to suit the network it is connected on. It can either be entered manually or configured
automatically using the DHCP option. When the DHCP option is enabled, this entry is grayed out.
IP Network 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.
IP Gateway
This is the address of the device that links the local network the UltraMatrix Remote 2 is connected to another network
such as the wider Internet. Usually the actual gateway is a network switch or router and it will be used whenever a
required address lies outside the current network.
VNC Port
This is the logical link through which communications with a remote VNC viewer will be channeled. The default setting
is 5900 which is a widely recognized port number for use by VNC software. However, in certain circumstances it may
be advantageous to alter this number.
HTTP Port
This is the logical link that communications with a remote web browser will be channeled. 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.
IP Access Control
This section allows you to optionally specify ranges of addresses which will or will not be granted access to the
UltraMatrix Remote 2. If this option is left unchanged, then the default entry of ‘+0.0.0.0/0.0.0.0’ ensures that access
from all IP addresses will be permitted. If this feature is needed, please see Appendix E for a detailed explanation of
IP access control.
