3 - Communication
To browse to the device you normally need a xed IP address – the IP address is the address you
enter in the browser. If you use a portal service or WDB, you can use DHCP. This means that valid
network settings are sent automatically to the device.
Enter the correct settings in the elds and click the "Update" button to send the settings to the
device. Then click "Restart". This is necessary because the settings are not applied until the device is
restarted. You will lose contact with your WMPro for a few minutes while it restarts.
Type the new address in the browser address bar and log in again. This WMPro can now be accessed
from all computers in the network.
3�6 Broadband or ADSL connection
A WMPro can be connected directly to a broadband socket or an ADSL modem. However, you are
always recommended to use a router. That way, you can combine multiple WMPro devices to form
a separate network, all sharing the same Internet connection. A building might have several WMPro
devices that need to share information with each other. This is much easier to achieve if they are in
the same network. You can nd out more about WMShare in 18.8.
Broadband sockets and ADSL modems normally use DHCP, so there is no way of knowing the IP
address allocated to a particular WMPro. That is why you also need to connect the WMPro to some-
thing called a portal, which keeps track of the allocated IP address. Otherwise the device will drop
out of the network.
If you are using a router to connect WMPro devices, the devices should have xed IP addresses
within the internal network so their location is always known.
In the router settings you can access Internet services like dyndns, which keeps track of the router's
IP address and gives it a name, e.g. building.dyndns.com – this means that all WMPro devices con-
nected to the router can be access from the Internet. The router settings depend on the manufac-
turer and model, so please consult the router manual.
