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 to a unique address, just like the mailman delivers mail to 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 last number of an IP address can be different within a
network, so there is a maximum of 256 unique addresses within a network, ranging
from “xxx.xxx.xxx.000” to “xxx.xxx.xxx.255”. The first three numbers have to be
the same to make communication between several devices possible, otherwise 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 have to be the same. These first three parts
are called the “IP range”, so the devices have to be in the same “IP range” to
communicate with each other.
