5.Configure the ATC-3002
■Use this section to set up your computer to assign it a static IP
address in the 192.168.2.1 to 192.168.2.254 range with a subnet
mask of 255.0.0.0. The default IP address of ATC-3002 is
192.168.2.3, the computer IP user can not set this value,
otherwise it will cause IP address conflict.
This is necessary to ensure that your computer can communicate
with your ATC-3002. Your computer must have an Ethernet card
and TCP/IP installed. TCP/IP should already be installed on
computer using Windows 98/2000/XP and later operating
systems.
■Open your web browser and type http://192.168.2.3 in the browser’s
address box. This address is the factory set IP Address of your
ATC-3002. Press “Enter”.
