2. Setting up IP addresses for Network Devices

Once your network connections have been made, for the connected devices to communicate to each other you will need to specify the unique "IP address" for the device (i.e. like a house number, and street name so the house can be identified for posting letters).

There are two types of IP address; DHCP (Dynamic Host Configuration Protocol), which is more commonly known as dynamic addressing, and static. Dynamic is used when you have a router, set-top box modem or a PC/Mac with DHCP server enabled, as they can automatically give each device an IP address upon physical connection. We encourage the use of dynamic addressing as this is the default mode of the 640H, and therefore no further setup would be required for the 640H.

Note: With a DHCP assigned IP address, it is possible that the 640H will have a different IP address assigned to it, if left switched off over night. This is normal and will not cause a problem.

We recommend using static IP addressing for peer-to-peer networking only. The static address will not change unless you manually change it. This is particularly useful for network troubleshooting.
