4) Connecting a computer

AcomputercanbeconnectedtotheAMP523/RM523viaethernetconnection.Thisis

connectionismadebyaCAT5cable.(UsetheRJ45connectorwhichismarkedwith

followingaddressinyourinternetbrowseraddressbar:“http://192.168.0.193”(Thisis

thefactorydefaultIPaddressoftheAMP523/RM523andcanbechangedintheuser

interface).ThedefaultpasswordfortheAMP523is:‘AMP523’andfortheRM523is:

‘RM523’.

Configuring the AMP523/RM523

1) Changing the IP address

YoucanskipthisstepwhenthedefaultIPaddress“192.168.0.193”isnotusedby

anotherdeviceinyournetwork,andisOKforyou.IfyouliketochangetheIPaddress,

gotothe“Setup”menu(clicktheiconintheupperrightcornerofthemainscreen)

andclick“NetworkSettings”.NowyoucanchangetheIPaddress,andclick“OK”to

applythechangesandsave.Afterwards,yourbrowserwillbeautomaticallyredirected

tothenewIPaddressoftheAMP523/RM523,andthedefaultIPaddressisnotlonger

valid.

2) Changing the password

YoucanskipthisstepifthedefaultpasswordisOKforyou,buywealways

recommendtochangethepassword,especiallywhenyourdeviceisconnected

toapublicnetworkwhichexternalusershaveaccessto.Ifyouliketochangethe

password,gotothe“Setup”menuandclick“Passwordsettings”.Hereyoucan

changethepassword.First,theoldpasswordneedstobeentered,andsubsequently

thenewpasswordneedstobeenteredtwice(Max10characters).Pressthe“OK”
