Appendix F:
The scalable nature of Axia Livewire audio networks makes it possible to construct systems of any size - from a
single room to an entire multi-studio facility.
Since Livewire components – Audio Nodes, Elements, StudioEngines, etc. – are connected with Ethernet, each
one requires a unique IP (Internet Protocol) address. IP addresses are four bytes long and are written in "dotted
decimal" form, with each byte represented decimally and separated by a period. For example, in the IP address
193.32.216.9, the 193 is the value for the first byte, 32 for the second, etc. Since a byte can hold values from 0 to 255,
this is the range for each decimal value. If you run a public network, Host IP addresses are assigned to your organiza-
tion by your internet service provider and parceled out to individual host computers by your network administrator.
He may give you this number to be entered manually, or could opt for DHCP (Dynamic Host Configuration Protocol)
to let your computer get the address automatically from a pool. Because Livewire devices are permanently attached
and because it is more desirable to know the IP address attached to a particular node (and perhaps assign them in
some kind of logical pattern), we do not support DHCP for our hardware nodes. Therefore, you will need to enter an
IP address into each node.
Using the audio nodes, Livewire systems can support 32,766 channels of audio; this necessitates giving each audio
source or destination its own unique identifier, called Channel ID numbers.
As you can imagine, keeping track of so many unique IP addresses and Channel ID numbers is a big job. There-
fore, on the next few pages, we've provided you with worksheets that you can use to keep track of the numbers you've
assigned.
For a more detailed explanation of IP addresses, subnet masks and related issues, we highly suggest that you refer
to "Network Engineering For Audio Engineers", Chapter 8 of our Introduction to Livewire: System Design Reference
and Primer.
