IP Basics
Many AUDAC products are controllable by Ethernet. The Ethernet connection which
is used on the AUDAC products is TCP/IP based, like 99% of the computer networks.
There are some basics which you need to know to successfully make a TCP/IP Ethernet
connection.
The data in TCP/IP networks is always send in packages, all these packages must be
delivered at an unique address, just like the mailman delivers mail at your home mailbox.
In TCP/IP networks, this address is called the “IP address”. The IP address is always a
number in the following format “192.168.000.001”. As you can see, this address consists
of 4 separate numbers ranging from “000” to “255”.
In simple terms, only the latest number of an IP address can be different within a network,
so there is a maximum of 254 unique addresses within a network, ranging from “xxx.
xxx.xxx.001” to “xxx.xxx.xxx.254”. The first three numbers must be the same to make
communication between several devices possible, else the devices can not communicate
with each other.
Example:
Device 1:
IP address:
192.168.000.
001
Device 2:
IP address:
192.168.000
.002
Device 3:
IP address:
192.168.001
.003
In this example, Device 1 can communicate with Device 2, but not with Device 3, because
the first three numbers must be the same. These first three parts are called the “IP
range”, so the devices must be in the same “IP range” to communicate with each other.
