Operation on a Standard IP Network
Locating the Unit’s IP address
The unit is congured using on-board web pages. This can be done remotely once the unit has been
installed in its chosen location. The IP address of the unit is required to access these pages. When
the unit is connected to a DHCP network for the rst time, its IP address is unlikely to be known
without referring to the settings of the network switch or router it is connected to.
DHCP works by assigning an IP address at initial connection to the network. It is possible however
that this IP address can change without notication i.e. following power failure. DNS (Dynamic Name
Service) allows the unit to be assigned a meaningful name which can be used to reference the unit
instead of an IP address. This will remain constant in the event that the DHCP assigned IP address
changes. If you do not wish to assign a DNS name, a xed IP address can be assigned via the
Conguration Menu pages:Network Settings->Network->IP Address.
When the unit is powered up, the IP address can be found by viewing on a local monitor and
navigating to Conguration Menu pages:System Settings->Attributes->IP Address.
IMPORTANT: Refer to Appendix D for guidance on locating the unit’s DHCP assigned IP address
via a Serial Port connection to a PC / Laptop.
The easiest way to open the web pages remotely for the rst time and identify the assigned IP
address (via the Status page) is by connecting to the Unit using its DNS address.
Default DNS Address
The default DNS address for each unit is factory set to be its serial number. Therefore the address
can be found from the serial label on the unit or via the packaging the unit came in. The DNS
address can be typed directly into the address bar of a web browser on a desk/laptop connected to
the same local network as the unit.
Note: The unit’s DNS address can be changed subsequently to something more memorable
or meaningful than its serial number. It can be edited via the System name option in the
Attributes conguration page (System->Attributes).
Note: Following a change to the System name (DNS address), it will be necessary to reboot the
unit. The unit can be rebooted via System -> Maintain-> Reset.
The unit supports zero-conguration networking (sometimes known as Bonjour), this enables
automatic discovery of computers, devices, and services on IP networks. Zero-conguration uses
industry standard IP protocols to allow devices to automatically discover each other without the
need to enter IP addresses or congure DNS servers. By loading a suitable free add-on to your
web browser such as Bonjour for Windows for Internet Explorer or BonjourFoxy for FireFox zero
conguration devices such as this unit can easily be discovered and accessed.
The web pages loaded onto the unit can be navigated by connecting a monitor to MON A and the
provided USB mouse into one of the USB ports.
