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a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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must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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.
The“IPrange”ofhomeandofficenetworksaredefinedbythenetworkadministrator,
thismeansthattheIPrangeofyourhomeorofficenetworkcanbedifferentfromanother
network.
AUDACproductshavethefollowingIPaddressasdefault:“192.168.0.xxx”,thismeans
thestandardIPrangeofAUDACproductsis“192.168.000.xxx”.Ifyournetworkisusing
adifferentIPrange,theAUDACproductswillnotbeaccessiblefromyournetwork.You
canchangetheIPaddressoftheAUDACproductstomakethemworkproperlyinyour
network.Thiscanbedoneinthesettingsmenu,andisdescribedextensivelyinthe
“Settings”chapterofthisusermanual.
Ofcourse,tomakechangestothesettingsmenuoftheAUDACproduct’s,youmusthave

givingyourcomputeranIPaddresswithintheIPrangeoftheAUDACproduct,for
example“192.168.0.200”.AftertheIPaddressofyourcomputeriswithintheIPrange
oftheproduct,theuserinterfaceisaccessibleandtheIPaddressoftheproductcanbe
